Callmanager 5.0(4) and NIC redundancy

Hi,
I am currently installing a two callmanager cluster running 5.0(4).Everything works fine apart from the dual nic config.
I have used the set network failover ena command and both nics flash on the front of the server and the switches report that the link is up.
However when i go into OS admin the callmanager thinks that one of the NICs is down.
Anyone seen anything like this.
cheers
mark

What type of server is it. Cisco dont support NIC teaming on IBM platforms. It is supportd only on HP platforms.

645E Max HD and NIC problems?

I'm having three problems with my 645E Max and I'm not sure if they're with the motherboard or the hard drive and NIC.
Here are the problems:
1. Occasionally when I start my computer I get a "Hard drive: Imminent failure. Backup and Replace" error message.
2. Sometimes when I boot up, my computer goes in an very long loop. It restarts itself about 20-30 times before getting into windows.
Up until this point it sounds like a HD problem... but the HD seems to be working fine otherwise.
3. The NIC sometimes doesn't seem like it's getting power (the lights on the back don't light up) when I turn it on. Restarting usually doesn't help, but moving the NIC to another PCI slot usually fixes the problem. ((It's not a bad PCI slot, since moving it from one to another, and then back to the original one also fixes the problem))
Suggestions?

hehe..ok.. i had the same problem with my hdd's.
all i did was to switch places on the ide cable. fixed the problem. strange =)

Load Balancing and NIC Teaming

Hi! i have been looking through lots of links and none of them actually can fully answer my queries.
I am to do a writeup on load balancing and NIC Teaming, is there any1 that knows what are the commonly used load balancing and NIC Teaming methods, when to use each method, and the advantages and disadvantages of each method and the configuration for each
method!
Sorry its lots of questions but i have to do a detailed writeup!
Many thanks in advance :D

HI
NIC Teaming - On a single server, you will have mutiple NIC. You can Team the NIC so that both NIC will act togather to provide better bandwidth and High avaliblity.
Example : NIC 1 - 1 GB and NIC -2 1 GB so in Team it can act a 2 GB single NIC, If one fails speed will be reduced but it will have HA
Loadbalancing : Two servers hosting same content:
Example : Microsoft.com can be hosted in two or even more servers and a loadbalancer will be used to split load to each server based of the current load and traffic.
No disadvantages

Relationship between coherence and NIC teaming

Hi,
We are using Tangosol coherence for clustering purpose in our product Webmethods Integration server.
When our server starts up it tries to jojn tne cluster.
Our scenario is this :-
We have 2 servers running on 2 separate boxes A&B.
They are on same network segment.
Multicast test is working properly .
The issue is only one of the nodes(which is started first) in becoming the part of the cluster and other one remain disabled.
We found out that the NIC teaming was disabled in the boxes.
When we enabled NIC teaming with smart load balancing then both the nodes are able to join the cluster.
My specific question is,
Is there any relationship between Tangosol coherence and NIC teaming? If yes, what's the relationship.
Regards,
Ritwik Bhattacharyya

I did some tinkering a while back trying to get 4Gb/s bonded etherchannels going on linux boxes but I had issues with out of order and missing packets:
4Gb/s bonded ethernet test results - finally...
But to answer your question there is no reason that you would need NIC teaming on in order to make Coherence work. It sounds like something is not configured correctly with your NIC or switch. Maybe try connecting the machines with a crossover cable instead of a switch just to eliminate the switch as a possible problem. It sounds like maybe you're just using the wrong ethernet port on a server or something.

CSS sticky and load redundancy

CSS has been configured with one VIP which has four real servers behind the VIP. We would like that clients always being dispatched to server #1 for application access, and be able to access the rest of servers if server 1 fails, in other word, we just like the CSS support sticky base on Soruce IP and load redundancy, not load sharing, is this feasible? is there is any parameter could be twicked? Thanks in advance

The CSS allows you to use cookies or URL strings to stick to a particular server. In the past, this has required the Web hosters to modify their applications to set particular cookies or strings in the URL. For more information have a look at the following URL.

Firefox keeps crashing randomly. I've tried refreshing, reinstalling, and clearing redundant plugins. Help please...

Hi,
My Firefox keeps crashing, seemingly randomly. It could be when I open a new page, or when just reading through a page of text.
I've tried starting in safe mode, doing multiple refreshes, reinstalling Firefox, and disabling redundant plugins like multiple shockwave.
Any help would be appreciated. I love Firefox, but this has been making it extremely frustrating to use.
Here are just a few of the crash reports from the last few days:

Thanks,

hi Josh, that looks like a crash triggered by your nvidia graphics driver in relation to hardware acceleration in firefox - please try [[Upgrade your graphics drivers to use hardware acceleration and WebGL|updating the graphics driver]] for your model on the nvidia website, or in case this doesn't solve the issue or there is no new version available at the moment, disable hardware acceleration in the firefox ''menu ≡ > options > advanced > general'' (that setting will take a restart of the browser to take effect).

Gross up Taxes and NICs together(taxes+NICs)

s there any way you can Gross up both Taxes and NIC together? How do I go about this? Any step by step procedure or SAP note about this?

ok

VIP and Interface Redundancy

Yet another question...
I am running two CSS 11501 using VIP and INT Redundancy. One thing I am a little confused about, based on the sample configs and documentation is the following statment.
"Typically, you configure VIP redundancy on the public side of CSS peers that are positioned in front of a server farm. You configure virtual interface redundancy on the private-side interfaces attached to the Layer 2 device in front of the servers"
This sort of makes sense to me. Except if I only configure VIP redundancy on the public side of the CSS how do I route my packets from my firewall to the CSS for servers behind the CSS that are not VIPed - if I do not use Interface redundancy on the public side as well, then I have to route the packets to the physical interface.
I guess the question is - can I use interface redundancy on both the public side and the Server sid of the CSS as well as VIP Redundancy on the Public side??
Thanks,
Heath

Heath,
that's no problem.
You can turn on interface redundancy wherever you want.
The documentation just refers to the most common situation.

Gilles.

Jabber for Windows 10.5 and global redundancy

Hi All,
I implement J4W 10.5 in a full redundant environment, that contains:
- 3 x CUCM 10.5
- 2 x Unity Connection 10.5
- 2 x IM&P 10.5
- 2 x Expressway-C 8.2.2
- 2 x Expressway-E 8.2.2
After testing, I notice that the redundancy/failover does not act the same way depending the product, sometime no.
As it is not clearly stated in the documentation, what is clearly supported as automatic failover, and what's not, when using Jabber for Windows 10.5?
In my first test, I saw that Jabber does not support failover with UnityConnection: if the primary peer is down, no more voicemail on Jabber.
If jabber run in Mobile and Remote Access, and the Expressway where it's conencted goes down, it doesn't switch to the other peer.
It will be good to have a document that relate all the redundancy and failover support with Jabber, what can we expect during the failover process.
It will help a lot of people.
Thanks
Gabriel

Yep, that's what I did now.
But keep in mind this is not really explained, even if crossing all the documentations.
There is no document explaining what behaviour to expect in Jabber in case of redundancy of all the UC components.
For the CUCM, it's not clear, and nothing is mentionned in case of MRA.
IM&P is documented, but nothing for MRA.
Expressays states about redundancy, but the behaviour to expect is not. Same for XMPP federation, no idea.
UnityConnection as well, nothing is explained.

Losing network connection and NIC acts weird from warm/hot weather/temperatures?

Hello.
Is there a known issue on MSI P43 NEO3-F (MSI-7514) motherboards' onboard RealTek RTL8168C (P)/8111C(P) PCI-E Gigabit Ethernet NIC network disconnecting and acting weird during warm/hot weather?
I noticed lately and back on 1/11/2009 night when weather got warm/hot (e.g., my room can get over 85F degrees, but lately it has been 80F degrees), my network would lose its connection. See http://img9.imageshack.us/img9/5580/screenshots.gif for a few SpeedFan's sensor readings when the incidents occurred. I have never seen this happen when the weather is cooler (60-70F degrees in my room).
I also think this only happens if I am using the PC lightly (nothing intensive) like watching fullscreen videos (video overlay), surfing the Web, etc. I don't see any errors or evidences that it happens when idled (e.g., asleep or out). Uptime doesn't seem to matter since I have seen days to 3.5 hours.
I tried upgrading network driver twice (e.g., Realtek_XP_5714_0219 from
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false ...), disabling Kerio Personal Firewall v2.1.5 (XP's disabled already), releasing and renewing IP address (works, but still no network -- can't even ping my router!), unplugging and replugging the cat5 cable (do see the network port lights on), touching the network jack and hardware inside and outside of the case (not hot), trying another cat5 cable and a network port on a switch instead router's), changing from "Minimal Power Management" to full power (no underclocking/slowing down when idled), etc.
During the disconnections, I tried:

I also noticed the disconnections usually start with red X icon in my taskbar with its bubble and then later the long disconnection even though no red X (1 GB and connected). If I were to disconnect the cat5 cable from NIC, then it wouldn't even detect it is missing the cable!
The only way to fix this was to reboot (best way and last longer) OR disable network connection and re-enable it (Windows XP's Network Connections) or the NIC itself (Device Manager), but that doesn't always last long (maybe a minute). Example of my pings right after disabling and re-enabling NIC:

Force your NIC to run at 100Mbps full duplex and see how it goes.
Check your router / switch ports as well as cables.
I will try 100 Mbps if it happens again. So far, it hasn't occurred after installing the driver supplied by MSI's Web site and not RealTek's Web site. The room temperatures even got warmer like 83F degrees.
As for router and switch, what am I checking for? Other computers didn't have any problems. As for cat5 cables, I already tried another one like I said in my original post.

Hard Drive and NIC Serial #/ID

How can a LabVIEW program get a hard drive and/or NIC serial number/ID in
Windows?
I'd like to programmatically get this information to provide an "unlock"
code for software that has been paid for.

It is the volume serial number. Is this something that can be changed in
the registry?

RMAN retention policy - backup spfile and then redundancy = 5 removes it.

I have a database that is Oracle Standard Edition and it is version 9.2.0.6.
The spfile has not changed since November, 2005. A list backup does not show an spfile backup with a tag of "hot_database_spfile_backup_full". I took a close look at the RMAN script log and was shocked to discover that the spfile backup from the current day is being deleted. Is that because of the redundancy = 5? I'm trying to figure out why a backup piece from the current day is being deleted?
Examples follow.
The script deletes obsolete with redundancy = 5, however, I believe the intent was to keep 25 days because one of the configure clauses is set to a recovery window of 25 days. I realize that the redundancy overrides the configure retention policy command. I can fix the script and remove the redundancy = 5.
In the RMAN run statement, I first resync the catalog, backup the spfile, a full backup of the database including current controlfile plus archive log (delete input), resync catalog, switch logfile, and backup any additional archive logs. The backup looks fine.
Then, I allocate a channel for maintenance type sbt. The script then has a "delete noprompt expired backup;" a "delete noprompt obsolete redundancy = 5;" and finally, a crosscheck;
example of backup piece that is later deleted:
Starting backup at 07/18/2006 20:00:14
channel t1: starting full datafile backupset
channel t1: specifying datafile(s) in backupset
including current SPFILE in backupset
channel t1: starting piece 1 at 07/18/2006 20:00:14
channel t1: finished piece 1 at 07/18/2006 20:00:15
piece handle=P*****_2338_1_596145614_FULL comment=API Version 2.0,MMS Version 5.2.0.0
channel t1: backup set complete, elapsed time: 00:00:01
Finished backup at 07/18/2006 20:00:15
deletion:
Deleting the following obsolete backups and copies:
Type Key Completion Time Filename/Handle
<other lines deleted>
Backup Set 27453 07/18/2006 20:00:14
Backup Piece 27454 07/18/2006 20:00:14
P*****_2338_1_596145614_FULL
deleted backup piece
backup piece handle=P*****_2338_1_596145614_FULL recid=2039 stamp=596145614
Deleted 12 objects
Why is a backup piece created on 7/18 being deleted in the maintenance step?
Thanks in advance!

In the next step in the script, the controlfile and spfile are backed up:
backup
full
skip inaccessible
tag hot_database_backup_full
format '%d_%s_%p_%t_FULL'
(Database
include current controlfile)
Plus Archivelog delete input;
Even though my backup script is redundant by backing up the spfile twice, when I list the backup of the spfile, I would have expected to find 5 backups with a tag of hot_database_spfile_backup_full and 5 with a tag of hot_database_backup_full. That is not the case. I only find spfiles with a tag of hot_database_backup_full. i am still perplexed by RMAN.
I will modify my script - remove the backup of the spfile, and crosscheck before the delete commands. I will also remove the redundancy = 5. The intent is to keep 25 days of backups.
Thanks for your comments

NEED HELP PLEASE Setting up 2 VLANS and a redundant WAN connection

I have a remote branch office which is actually a huge bar/lounge. The bar wants to enable patrons to access the Internet with their wireless laptops. I want to prevent those patrons from accessing our private network, and also prevent them from traversing our static VPN tunnel back to HQ.
The bar processes all credit cards via the T1 connection, and this has caused us to lose money every time the T1 goes down while we're open, since there is no WAN redundancy right now.
Here is my current hardware configuration:
1) one PIX 501 50-user 3des.
2.) two Dell 3024
3.) one Aironet 1100(g) AP.
Current LAN Network: 10.35.35.0
(internal employees only, static VPN tunneled to remote HQ network)
Current Wireless SSID's:
SSID1=PRIVATESSID
SSID2=PUBLICSSID (not currently in use, waiting to figure this out)
Current WAN: one T1 connection.
WHAT I WOULD LIKE TO DO AND NEED HELP FIGURING OUT:
#1a) I want to create two separate VLAN's that are able to share the WAN connection, but not be able to "see" each other.
#1b) These VLAN's would be mapped to their respective SSID's on the AP (PRIVATESSID>10.35.35.0 and PUBLICSSID>192.168.1.0).
#1c) The 192.168.1.0 network should not be able to traverse the static tunnel between the branch site and HQ.
#2) I would like to install a backup WAN connection such as a modem 56k dial-up to an ISP or a cable modem to an ISP. In case the primary T1 goes down, I would like the router to automatically dial out over the modem conection and route all Internet bound traffic over that backup WAN connection, until the primary comes back online.
Question 1:
I'm assuming I need a router to do the intervlan routing. Could this router also do the on-demand WAN backup dialing to an ISP via analog modem?
What IOS version and flavor (IP base, IP+, etc.) would I need? What is the cheapest router I can do all that with (i.e. 2620/2621/1720/3600 series)? What WIC's or NM's would I need?
Question Two:
I would like to prioritize PRIVATESSID's traffic over PUBLICSSID's traffic, which I know I can do on the access point. Can I do this on the router so that any 10.35.35.0 traffic takes priority over any 192.168.1.0 traffic?
Question Three
If the primary T1 WAN connection goes down, I don't want the router to re-route the 192.168.1.0 traffic over the backup 56k dial-up WAN connection. That traffic can wait until the T1 comes back up.
Any help you can provide would be very much appreciated.

Assuming your access points can place SSID into separate vlans and support 802.1q trunks then I can attempt to answer your questions. There are seperate secuity issues with both SSID for protection and VLANs for seperation but in your case in may be minimal.
q1
Any cisco router that will run 802.1q trunking will work. Since you are looking at older routers you will need IP+ to get it. Even 2610's will support 802.1q on their 10m ethernet at the correct code level but 10m and 802.1q is sorta nonstandard. Since your backup is only 56k you can use the internal modem port as a dial backup. A wic-2a/s will also work if you prefer not to use the modem port. You will need some wic to run your t1 line. If you are planning to leave the t1 on another router it makes the next 2 questions much harder.
q2
This is fairly simple and depends on your ios level. "priority queing" is supported on even the older software. I assume you do not control the far end of the t1 line since it sounds as if this goes to a ISP.
You will need to have them do the QoS since most issues with the internet are inbound and not outbound. You can only control outbound traffic.
q3
If the T1 is on the same router then this is fairly simple. You can just put a floating static default route in that will cause the dialer to come up if the the t1 goes down. There is no easy way to protect against the line being up but no traffic passing. This is also why it would be best to have the t1 on the same router. If its not you will need to get very creative to solve this. You could build a GRE tunnel to a remote location and montior the tunnel or run a routing protcol over the tunnel. In the newest software you could use SAA and policy routing to force the traffic over the dialer but the router must support ios 12.4.
3a. You mentioned a cable modem as a backup. That can be much easier sometimes since it is all routing and no dialer interfaces with nasty modem issues. This does not make the issue of the t1 not on the same router easier.

Switch and Router Redundant Network

I am trying to learn as much as possible about networking and cisco. I trying to build the following network to practice redundancy. I set up HSRP on my routers because it the only protocol available on packet tracer. The following setup works but how would I go about adding the vlans to switch ALPHA and switch BETA. I would like to use access list for security, for example Sales can't access Accounting but Accounting can access sales. I can do that with one layer 3 switch but how do I do it with 2? Do I add the same VLans to both switches? Should the configurations to both switches be exactly the same? Because I tried that and for some reason the Vlans could not communicate unless I changed the interface to dot1q and trunk mode. I thought it be easier to change all interfaces at one time but when I tried that STP failed. I tried setting only the interfaces being used to dot1q and trunk mode on one switch it worked but as soon as I did it for the other STP failed again. Read layer 3 switches can have HSRP but seems like a waste of a switch. Ive looked online and can't seem to figure it out. So my question is how do I set this up, I would like to add hosts and a server later but I can't even get this to work. Hopefully someone can help me out with this as I find it very interesting and am eager to figure it out.

Ok thanks again John. I will set that up as soon as I can. But the issue I was having don't know if its because of HSRP not configured but when I did identical configs on both switches I couldn't ping between Vlans unless I changed the interface, for example the interfaces between Sales to Alpha then Alpha to Marketing, using the command
Switch(config-if)#int f0/?
Switch(config-if)#switchport trunk encapsulation dot1q
Switch(config-if)#switchport mode trunk
for both interfaces.
It worked ok until I did the same thing for the interfaces between Alpha and Beta then STP turned off and everything started blinking. But I had to because I couldn't get to Accounting without doing that to Beta since STP blocks ports and sends traffic through Beta also.The I tried using the same command on all the interfaces for Vlan switches Sales, Marketing, Acc instead of Alpha or Beta to try something different and same thing happened. Not sure if you know why its happening? Wrong interface encapsulation or mode on either side? needed HSRP?
Basically if I change all interfaces on Alpha and Beta to dot1q and trunk mode STP fails or if I change all the interfaces and the bottom switches to dot1q and trunk mode everything also fails.
I guess I try what you said first if it fails I show you what I'm talking about.
Thanks,
John

Itunes wont start unknown error (-69) and cyclic redundancy check

I use an ipod shuffle and am on itunes 6 (or 6.1 maybe) on my windows compaq presario laptop. I was burning a number of disc from itunes and all seemed ok. The shut the computer down and the next day came to do the same thing and itunes wouldn't start the application with an unknown error (-69). I am also getting a cyclic redundancy error when I try to delete some music or picture files now aswell. I have tried to uninstall itunes and reinstall but this hasn't helped. I thought I might delete all my music and pictures off the hard drive as they are also copied and stored on an external drive but it wont let me delete certain music and picture files now. Can anyone help. Have tried to do a CHKDSK on my pc but that's not helping either and it is running very slowly now. Anyone had the same problem and been able to resolve it??

When you install from a CD, that CD could have been manufactured several months prior, and not have the latest anti-virus definitions.
While an internet connection is probably the most common vector for an infection, its not the only possible one. Any CD, removable drive, etc could be the source for a virus.
Because the computer is also running slow, its possible you have other applications running in the background. Some of which may have been inadvertantly installed.
