CSS 11501 - Network reconnection issue

Using a CSS 11501 switch to configure both Load balancing and server hot standby between two servers (of same config). Clients are connecting to the server using tcp/ip sessions.
The configuration used is shown below:
=========================================
configure
ip route 0.0.0.0 0.0.0.0 10.167.50.1 1
!************************* INTERFACE
interface e2
bridge vlan 9
interface e3
bridge vlan 9
!************************** CIRCUIT
circuit VLAN1
ip address 10.167.50.108 255.255.254.0
circuit VLAN9
ip address 10.167.70.1 255.255.254.0
!************************** SERVICE
service abc_service1
ip address 10.167.70.2

!*************************** OWNER
owner xxxxx
content abc_crule
vip address 10.167.50.109
add service abc_service1
add service abc_service2
protocol tcp
port 6300
balance aca
active
===============================
We conducted three tests to verify the hot standby while client sending the data to server app thro tcp/ip.
1) Brought down the service on one server 2) Restarted the OS (Windows 2003) on one server 3) Removed a network cable of one of the server connecting to CSS.
client app lost the conn to the service/server, but when it tried reconnecting to the alternate server, it was successful.
CSS status reflected the actual status of the service/server.
But in third test (removing network conn) the service state changed from "Alive" to "Down" and client app lost conn to the server. Client app tried reconnecting and it was successful connecting to the alternate server.
But when we connected the network cable back, the CSS state was continue to be in "Down". Also,the network connection between CSS and server was not available after reconnection. Also, the status of alternate server changed to "Down", but still client app was successfully transmitting to the alternate server. Stopping the client app and tried reconnecting,
the connection was not going thro.
The connection could be established between CSS and server boxes only after restarting the OS(running windows 2003).
Issues:
1. Service status in CSS continue to be down even after reconnecting the cable with the service running.
2. CSS status of the first service also went down after reconnecting the other server.
3. Client app could not reconnect to any of the servers.
Are we missing any configuration parameter in CSS which will address the above?
regards
Param

Param,
what software version for the CSS ?
Did you see an ARP entry on the server for the CSS ?
Did you see an ARP entry on the CSS for the server ?
is the server directly connected to the CSS or is there an L2 switch inbetween ?
Could you configure 'bridge spanning-tree disabled' on the CSS and see if this improves the situation.

Gilles.

CSS 11501 Load Balancing Issue

Hi,
We are facing some issue in load balancing in cisco CSS 11501 as we are not able to access the application through virtual IP. Below is the ruuning configuration of the CSS:

Observation : We are able to telnet on VIP: 132.186.199.146 on port 5001, but not able to access the application.
In Actual scenarion customer access application by accessing URL: http://132.186.199.243:5001/emi and once he enter this URL in web browser the request redirects ( by server itself) to URL: https://132.186.199.44:6002/cas/login?service=http%3A%2F%2F132.186.199.243%3A5001%2Femi%2Findex.jsp&acceptStrength=BASIC on backend server for user authenticaton and once user is authenticated then it again redirect to main URL ( http://132.186.199.243:5001/emi ) to access the application but when we are trying to access the application through VIP ( URL: http://132.186.199.146:5001/emi) we are not getting the login page as the request is not gettting redirected to backend server for user authentication.
Please suggest a solution here.

The problem is that you are in one-armed mode.
So you need to configure client nat.
Without nating the client ip address, the server response goes back directly to the client and bypasses the CSS.
Therefore the client receives a response from an unknown server ip address (not the vip).
So configure a group.
For example
group Client
    vip address 132.186.199.146
    add destination service Server1
     add destination service Server2
    active
Also, remove the url command from your content rule.
It is useless in your case and will just make performance worst.

Cellular reconnectivity issues with 3rd Gen iPad 3G/4G/LTE

I've read a few other threads regarding a reconnection issue with the new (3rd Gen) iPad. I'm creating a discussion so people can put there thoughts here regarding the issues they are having with reconnection of cellular data connections.
I have AT&T 64B iPad Gen 3 with 4G/LTE. Black. Works just fine on wifi and my LTE screams at home and work. Faster than my cable at home. I have noticed something behavior regarding data connection when it's lost (like in a tunnel). I ride DC Metro to work and go through a few tunnels. Of course, my data connection drops in the tunnels. When I come back out the indicator on the iPad indicates 5 bars signal and LTE again. Problem is the data connection isn't there, no matter what app I try. I even get a popup window say my cellular data plan has not been activated (huh?). This isn't true since I am on, and have been using a plan. It does this whether it's 4G or LTE reconnection. Not sure about 3G because I haven't seen 3G icon popup on this iPad yet.
I'm thinking this may be an authentication issue? Else, why would it popup that warning? Anyway, all I do is is go into settings turn cellular data off and back on again and everything is fine.
I'm guessing that there could be a software fix for this in the future as there are quite a bunch of people having this problem with reconnection to cellular.
Please post your issues here in this discussion if you have this problem. Maybe we can figure something out.

I have the same iPad (3rd gen, 4G ATT, 64GB, Black). When it arrived last Friday, everything seemed to work fine, except the cellular data connection. It would constantly drop, and I had to toggle cellular data off and back on to get it back. Also, I was getting really slow speeds (on cellular data only - wifi works fine). I tried some simple fixes (restarting, resetting the network settings, restoring), but I kept having the problem. I finally made an appointment at the Genius Bar, and they immediately gave me a new iPad, saying "it could be a bad antenna." Here is the bad news. Even with the replacement, the connection seems to drop less often, but it still drops. The part that concerns me most is that the data speeds on my iPad are considerably slower than on my iPhone 4S when I test them in the exact same spot (I use the Speed Test app). So on my iphone, I get speeds around 3 Mbps, and on the iPad, I get speeds of less than 1Mbps. I can't see any logical reason that the 3rd gen iPad would not get at least as good or better data speeds as an iPhone 4S. The fact that I have now had two 3rd gen iPads with cellular data problems concerns me. However, it is very hard to tell if this is a software, hardware, or network issue. The fact that my iPhone is running the same update of iOS (5.1), and has no problems would seem to eliminate the software and network as causes, but I can't really be sure. I am going to watch the posts in the support communities for another day or two and then head back to the Genius Bar. Overall I love the new iPad, but this has been a real downer.

CSS 11501 StartUp Problem

Hi all,
After i boot up for the first time, the CSS asked for change User/Pass, wich i perform a well known ones.
After that it's always impossible to login.
Is there any way of return to factory default Settings?
or
Is there any password recovery procedure?
or
What are the default User/Pass of the equipment?
I already done a Power Off/On on it with no results.
Best Regards,
Petr?nio

Hi,
I perform the password recovery, as it was documented and then its always getting the "CSS 11501 Offline Diagnostic Monitor menu (OffDM)" Menu, even if i dont press the Y key in the bootup question "Would you like to access the Offline Diagnostic Monitor? (Y)"
Any ideias?
How can i test the login i changed before?
Here is the bootup logging that appear's.
I'm not pressing any key.

CSS 11501 - SNMP sysname

Hi All
Had a basic query on SNMP polling for CSS 11501..
Im polling a CSS through Ethernet Management Interface, and the SNMP servers are detecting the system name as "Support" instead of the hostname of the device..
SNMP get sysname from x.x.x.x with ****
.1.3.6.1.2.1.1.5.0 = Support
Is there a way to alter the SNMP sysname, to be identical to the hostname of the device ? I dont have issues with other components like routers, switches etc..
Raj

Hi Sachin,
Use the snmp name command to set or modify the SNMP name for this system.
You can specify only one name.
The syntax for this global configuration mode command is as follows:
snmp name "name"
Enter the SNMP name as the unique name assigned to a system by the administrator.
Enter a quoted text string with a maximum of 255 characters.
The standard name convention is the system's fully qualified domain name (for example, [email protected]).
For example:
(config)# snmp name "[email protected]"
To remove the SNMP name for a system and reset it to the default of "Support", enter:
(config)# no snmp name
Best regards,
Sachin Garg

CSS 11501 Trouble shooting data throughput

I have two groups of servers that talk to each other through the Load Balancer. It appears that on certain transactions where there is a "get", "head" or "trace" in the actual http data, the transaction is not forwarded through the CSS 11501. This happens maybe once in 11,000 transactions. It appears the word get, head or trace has to be in a certain part of the data payload to cause this problem too occur. Has anybody heard of such an issue? If so, do you have a work around? If not, any suggestion on how I can further isolate the issue. FYI I have a TAC case open but it does not appear to be going any where any time soon.

is it happening in the middle of a persistent connection or with the first request ?
There are 2 possibilities I can think off.
First one would be a flow timeout and the next request is just dropped because the css reclaim the fcb.
The 2nd option is that by default the CSS does not support the "TRACE" http method.
It must be enabled.
See info at :
http://www.cisco.com/en/US/products/hw/contnetw/ps792/products_command_reference_chapter09186a008040c3cf.html
So, configure a flow-timeout-multiplier and enable parsing of rfc2518 methods.

Thanks
Manish

Hi Nicolas,
Why i am asking about DOS attack as i am facing some issues for the 2 VIPs configured in cisco CSS 11501.
Can you help me troubleshooting the issue?
I have coming across some Load Balancing issues for the 2 VIPS configured on Cisco CSS11501.
We have cisco CSS 11501. We have 2 VIPs configured on it for FE and BE servers.Now Client calls to FE VIP and LB forwarding it to server and then FE server calls the BE VIP which goes through the same LB and forward to BE server under the VIP.When we start load test, we have observed after 2 hour test, application team getting HTTP timeout.As this application is used by Call center so getting timeout is bad.
Need to troubleshoot this issue if there is any problem from LB End.
Please find the attached file for VIP configs.

Auto Network reconnect with Airport Express - tried all solutions so far

My G4 quicksilver will not auto network reconnect after sleep, or after turning Airport off and on again.
* I tried deleting and re-issuing a new LOCATION and new WPA mentioned at:
http://discussions.apple.com/thread.jspa?threadID=121824&tstart=150
* I also tried deleting network and airport preferences.
* I also made sure that I have the "distribute IP addesses" unchecked.
I still need to manually reconnect!
It used to work and show a nice scrolling network name when it found my network. After messing around with the AE configuration for another unrelated reason, this problem came up... OSX-4.2, without any change in months...
Help?

I have an iBook & an iMac on an Airport Express Network with WPA2 password security. Both are running OS 10.4.3, & are current with all security updates etc.
I set up both computers according to the suggestions of "Topic: Tiger and Lost Wireless Network Connectivity" by Duane, Henry B, iFelix, Alan Macdougal, & Dr Smoke. I created New Locations for each computer.
The iBook, now auto-connects just fine, but for the life of me, I can't get it to work on the iMac. The iMac is 3 feet from my Airport Express; the iBook is downstairs. What do I try next?

CSS 11501S GSLB DNS

Hi
I am in the process of planning for a GSLB failover solution for a web site. I have attached a very basic diagram showing an example of the topology.
The aim is to have two sites. A primary site and a DR site to be used as a failover solution.
The main site has two web servers that will need to be load balanced and the failover DR site will only have 1 web server.
My initial plan was to use 2 Cisco CSS 11501S devices as I believe this would provide the load balancing and GSLB functionality I require.
To achieve this I was going to use the CSS's as the primary and secondary name servers for the domain. This has raised a few question marksâ¦.
Both of our sites are connected to a private WAN (with private IP ranges). See attached diagram. Our internet access is provide through a third party âFirewall Portâ directly off the WAN. We don't manage the firewall that connects to the internet. This third party firewall provides the NAT for our public facing services (web servers, mail servers, ftp servers etc).
So my questions areâ¦
* Because the CSS's and web servers are located on a private network will the CSS's be able to respond to the DNS requests with the PUBLIC IP address (as seeen from the internet) of the servers as apposed to the private IP address of the servers? If the firewall in front of the CSS's was connected to the internet this could be done via DNS doctoring but our firewall is on a private subnet!
* Is it possible to get the CSS's to respond to DNS requests for other domain devices that do not reside behind the CSS - E.g. a MX record for a mail server that resides on another 'private' network?
*Is there a better way to achieve this?
Any assistance would be much appreciated!!

Thanks for the reponse Gilles. When you say
"If you configure the css to answer with the public ip address, you can't access your vip from the internal network anymore."
Do you mean that you will only get the public ip address from a DNS query and therefore this won't work locally?
If I have a host file entry providing the private address resolution for my internal hosts will this work?
"Also, be aware we do not support GSLB on the CSS anymore.
So, if this is a new install, it is better to start with a solution that we support - GSS"
Why is this no longer supported? Are there a lot of problems with GSLB on the CSS? It is pretty hard to justify the cost of a solution including 2 GSS's for GSLB and 1 CSS for server load balancing when comapred to the price of 2 CSS's with the enhanced license for both GSLB and server load balancing.
I have one client that wants to use their existing CSS's for a solution like this and another that is starting from scratch.
Thanks

Local director 417 replacement? CSS 11501 software 8.20

Hi,
i would like to ask if CSS 11501 (software 8.20) is still the replacement hardware for local director 417? currently we use this local director to load balance http and https traffic using a flat network implementation meaning virtual IP is in the same netwoork as the physical server. will CSS 11501 can support this implementation?
Current Local Director setup example
web server virtual IP   10.10.10.1
real server ip 1   10.10.10.2
real server ip 2   10.10.10.3
rgds,
mc.malinao

local director is well before my time, so I can't comment on those and their official replacement.
I'd say you're better off going straight to ACE modules or appliances.
They're the latest generation of Cisco's load balancers.
We're very happy w/ our ACE-20 modules.

High CPU utilization on CSS 11501 version sg0750303

Hi everyone,
I have the problem about High CPU utilization on CSS 11501 version sg0750303.
Our customer has used one pair of CSS 11501 (active-standby).
As a matter of convenience, called "Old CSS" after here in this post.
However traffic via Old CSS had been increasing so customer decided to add one more
pair (active-standby) of CSS to separate traffic.
Yesterday we installed new two CSS 11501 version sg0750303 (active-standby).
As a matter of convenience, called "New CSS" after here in this post.
Today, active CSS 11501 and standby CSS 11501 which were installed yesterday (New CSSs)
indicates High CPU utilization.
Active CSS 11501:
Peak CPU utilization: about 85%
Average CPU Utilization: about 60%
Standby CSS 11501:
Peak CPU utilization: about 40%
Average CPU Utilization: unknown
I do not understand why CPU utilization of both New CSSs become high.
The traffic pass through New CSS less than Old CSS, because the traffic is separated into
Old CSS and New CSS.
And CSS's configuration parameters (service, content, access-list) also less than Old CSS,
because real servers are also separated into Old CSS and New CSS.
Old CSS indicated average of CPU utilization about 20% before installing New CSSs yesterday,
in spite of all traffic pass through Old CSS only.
I wrote "New CSS remains High CPU utilization", however end users do not feel the
performance issue (e.g., performance delay, communication failure and so on) and
the traffic pass through New CSS normally.
So I have the question "CSS 11501 sg0750303 remains High CPU utilization on normal situation ?"
And customer uses MTRG to poll SNMP for Old CSSs and New CSSs.
So I have the question "CSS 11501 sg0750303 become High CPU utilization in case of receiving
SNMP polling ?".
Or if this situation is abnormal we need to start investigation.
Would you please let me know how do we investigate this situation.
I found the DDTS CSCek57080 "Performance issue using arrowpoint-cookie with ASR".
Release note of this DDTS says that
A customer was using a CSS pair configuration where arrowpoint-cookie
is being used along with a redundant-index on many content rules. When
the flow rate increased to a few hundred flows/sec, the peer message
queue of the CSS receiving ASR related message began to fill up.
When the peer message queue became over subscribed, the CPU increased
and the CSS became unstable.
New CSSs have configured redunrant-index on two content rules, and end users do not feel the
performance issue (e.g., performance delay, communication failure and so on) and
the traffic pass through New CSS normally.
So I think this DDTS does not related to this case.
Your information would be greatly appreciated.
Best regards,

Gilles,
Thank you very much for your cooperation.
I got the capture you instructed us.
The following are additional information from our customer.
At time user traffic path through the active CSS, active CSS indicates;
CPU utilization always range of 30% - 40%
Peak CPU utilization about 60% - 80%
At time there is no user traffic pass through active CSS, active CSS indicates;
CPU utilization always range of 0% - 5%
Attached files are named "Active CSS.log" and "Standby CSS.log".
"Active CSS.log" is captured on active CSS and "Standby CSS.log" is captured on
standby CSS.
I found the following process is using resource by looking the output of
"shell 1 1 spyReport" command.
On active CSS,
tFlowMgrPktR 8ba24070 50 26% ( 1469) 20% ( 26)
On standby CSS,
fmPeerMsgTas 8a511510 50 16% ( 176) 10% ( 7)
Your comment would be greatly appreciated.
Best regards,

EA4500 – Smart Wi-Fi interface and Windows Network Map issues

I purchased this Router about 2 weeks ago as a phased upgrade of our Home Network, primarily to enhance media streaming. It has the latest firmware preinstalled from the factory. Prior to the purchase and installation of the EA4500 Router I replaced my old Motorola SurfBoard SB6120 DOCSIS 3.0 Cable Modem with a Motorola SurfBoard SB6141 DOCSIS 3.0 Cable Modem. My old Linksys E2000 Router worked perfectly with the SB6141, with the exception that the E2000 wasn’t IPv6 enabled, but does have 10/100/1000Base-T Ethernet (RJ-45) and Internet ports.
The EA4500 has been installed for about 10 days and seems to have improved local network speeds and I don’t seem to be having any Internet connectivity issues. However, there are some disturbing issues with the EA4500 and the AE3000 I purchased. There are 11 devices connected through the Router; a Dell Desktop (wireless with the AE3000), a Dell Desktop (Ethernet), a Dell Laptop (wireless), 2 Canon Printers (1 Ethernet and 1 Wireless), 2 Western Digital 1TB MyBookLive Network Drives (both Ethernet), a WD TV Live Streaming Media Player (wireless), an Apple TV media player (wireless), an iPad (wireless), and an Android Smartphone (wireless).
Issue 1 – The Linksys Smart Wi-Fi interface appears to be unreliable at times!!! I’ve read about this problem here on the Community involving the EA6500, so I don’t know if this is a Linksys Server issue, as suggested in a few responses, or a bug in the Router firmware, or defective hardware. However, when the interface locks up, it can’t be accessed from a wireless or wired connection. Usually, powering down the Router and then powering it back up and restart will allow it to function again. However, at times before the interface completely locks up it shows either just a white screen or the security screen will show no firewall features enabled. This is a little scary, so I’ll do a complete reset and setup; this is becoming a pain in the rear!!!!! Is there any hope for this being fixed, in this Router, not the next generation??????????
Issue 2 - All of my network devices show up in the Router’s Device List. Except for the Apple devices they also show up, when they are online, in Windows 7 Explorer under Network and when you click on Network they are correctly displayed as Computers, Media Devices, Network Infrastructure, or Storage. However, when you click on “Open Network and Sharing Center” and then click on “See Full Map”; it fails with the response “Windows cannot create the network map. Responses from other devices on the network are delayed or there is an incompatible router on the network”; no device map is shown. When I follow the link for more information, the only thing that stands out is “A device on the network, such as a hub or switch, is not working properly or is not compatible with the Link Layer Topology Discovery (LLTD) protocol, which Windows uses to create the map. To fix this problem, disable the device, turn it off, or remove it from your network”. All of my network devices showed up on the Network Map with the old E2000. This issue is the same on all of my computers, either wired or wireless. Any known solutions for this, or is it as Windows suggests; an incompatible Router????
Thanks in advance for any insight or solutions. With the issues I’m having with the EA4500 and the AE3000; they are both probably going back to Amazon.

thebluemamba_24; Thank you for your suggestion; I finally found time yesterday to perform an extensive evaluation before I return the Router. However, rather than trying to add devices manually, my rationale was if the EA4500 can’t process them correctly, automatically, it needs to be returned anyway, so I added devices normally letting the device an Router handle the process.
In thinking through this issue, all devices on our network are detected and identified by Windows Explorer on Windows 7 computers; except of course the Apple and Android devices (Apple TV, iPad, and Smartphone). So, I wondered if one of those three devices being added to the Router’s device list was somehow causing issues or interfering with Windows 7’s ability to generate a Network Map. Therefore, my approach was to turn off or disable all devices on our network, reset the Router to factory defaults, reestablish the Router to my custom Home Network configuration using a Windows 7 PC that has LAN and Wireless access to the Router, then add one device at a time and check with each addition to see if Windows 7 could still generate a Network Map.
With the Router reset and reestablishment complete; I began the process of adding one device at a time and checking to see if a Network Map was being generated. What I discovered was when a recent addition to the network, a Western Digital WD TV Live Streaming Media Player, was connected (wirelessly), Windows 7 could no longer generate the Network Map and the failure was consistent. The only way to get the Network Map to work again was to remove power from the WD TV Live, although it remained in the EA4500’s Device List; simply turning it off didn’t help. Since I’d originally witnessed the Windows 7 Network Map working with the Linksys E2000 Router that the EA4500 replaced, I decided to test the WD TV Live with that Router. It worked initially, but it failed consistently after the first success. Interestingly, the failure indication was a little different, but nevertheless generation of the Network Map failed.
I’ve tried changing a few settings on the EA4500 as well as the WD TV Live, but nothing helped. There was a recent firmware update to the WD TV Live, so I might try rolling back the firmware to see if it makes a difference.
The Network Map issue might very well be an issue with the WD TV Live, not the Router, but after reading many threads on this Community I have reservations that the problems I’m experiencing with the Smart interface lockup will be fixed. I suspect new emerging replacement products will be the focus and these older products will be abandoned and no more firmware fixes will be forthcoming and I don’t want to spend more money for a new product just to fix old problems and get something that works properly. The Network Map issue is troublesome, but the lockup of the Router’s “Linksys Smart Wi-Fi” interface is a serious matter to me. It appears that once it locks up, the only way to correct it is a power off restart; not practical if you’re traveling and trying to access settings remotely; the selling point for this feature.
Given the problems I’m experiencing with the EA4500 and AE3000, I guess I’ll return them. Too bad, because otherwise the EA4500 seems like it’s a good Router. I’ve been brand loyal since the Linksys WRT54G came out, but after reading this Community and with my personal experience with the EA4500 and AE3000, now I’ll probably give the NETGEAR N900 equivalents a try.

The Game Center is "unable to load data due to network connectivity issues or errors".

The Game Center is "unable to load data due to network connectivity issues or errors".
My internet is fine: all other apps that do not rely on the Game Center work, as does my browser and other online functions; additionally, a friend's iPhone connects to his Game Center perfectly while he is sitting next to me.
Closing the Game Center app and then reopening it is ineffective. Opening the options for the Game Center in the settings, logging out of my Apple ID, then logging back in, and then reopening the Game Center is ineffective. Opening the options for the Game Center in the settings, logging out of my Apple ID, then reopening the Game Center app and logging back in from there is ineffective.
This issue has gone on for more than a month, and so the phone has gone through all variations of "turn it off then back on again, refresh the system, etc etc" that are the basic first suggestions for trouble shooting.
One game app, which required a Game Center profile to launch, stopped working entirely, and would return a message saying something like "connect to the Game Center". I eventually deleted it to free up space. Other games which can be linked to the Game Center to connect with friends simply fail to link, returning "Game Center unavailable". This is the aspect that is currently bothering me the most: I cannot play games with friends unless the app can also link to Facebook and connect to friends from there.
When I open the Game Center, I see the following screen. The bubbles float gently, and it seems as if I had the ability to update my "status". However doing so results in a message that has vanished once the app is reopened.
Upon tapping Games, either the bubble from the main screen or the option on the ribbon at the bottom, the following screen appears. Clicking on Challenges shows a message that achievements must be viewed to issue a challenge. Clicking achievements results in a message that games must be connected (and from my friend's phone I know I have several apps that should appear).
Upon tapping friends, it does show me a list of suggested friends pulled from Facebook, but attempting to send a friend request results in the following screen. After accepting the error box, the "send" button for the request is grayed out and unavailable regardless of adding or deleting friends and/or an accompanying message.
In short, the Game Center is completely unresponsive for no discernible reason, and this problem began with no warning and is now long term. Though my iPhone is older (a 4s), my friend's is even older (a regular 4) and works fine.

I am having the very same problem on my iPad running ios 7. All is fine on my iPhone it opens no problem - this is running on ios 8. I wish they would fix it.

How to reset password on Cisco CSS 11501?

Hi,
I have changed the password for the Admin user (which was SuperUser) but when I changed it I forgot to add "SuperUser" at the end, now I don't have SuperUser access to the CSS 11501.
Can anyone shade some light on this problem and explain how can I reset the password for a SuperUser?
Thanks in Advance,
Shai

Hi Shai,
You need to reboot the CSS. When prompt, hit any key to go into the Offline Diagnostic Menu.
When you get in the menu, you will go to Administrative options and create an additional Admin user. When you do this, DO NOT use "admin", use something totally different.
Get out of the Offline DM and reboot the CSS. When the CSS comes up, login as the new user (which will have Superuser rights) and run the "username" cli to change the password of "admin" and add the superuser part this time.
