WLC-2106 and multiple interfaces on the same network
Hi there,
I recently created a TAC request to the Cisco support regarding our WLC-2106, but they could not help me. Basically I just learned that you can create new interfaces for the wireless LAN controller and then dedicate them to a given wireless network (SSID). This way I could more effectively utilize network bandwidth also. Problem is that all of the interfaces have to be in a different network segment in order to work, which is not what I want. I specifically want to have several interfaces on the same network segment.
Has anyone tried to accomplish the same?
Basically what I've misunderstood is that all the traffic generated by our wireless clients have been going through the single 100Mbit/s ethernet port on the wireless LAN controller (management interface), and to mitigate this I thought I could create new interfaces (ports) and dedicate those to given WLAN networks.. I see now that this is not supported. Not inside the same network at least.
So, by reading further and consulting my best friend Google I learned about a setting called "AP Mode". Changing that from Local (the default) to H-REAP the APs should not route their traffic anymore through the management interface on the wireless controller, but instead route all the client traffic directly to the local LAN. This way you effectively remove the 100Mbit/s bottle-neck when all the APs were using the management interface both for configuration and client data traffic.
It seems you also have to enable H-REAP Local switching from a given WLAN network in addition to changing the AP Mode of your access points to H-REAP. I'm still in the testing phase here so should anyone have any insight to this, I'd be greatful to hear more.

How to use multiple Interfaces for the same BS?
Hi @ ,
Is it possible to have a scenarion where i am using multiple interfaces in the same BS based upon some conditional field in the message.
I amnot able to get the solution I know with condition editor I can have multiple receivers but in my scenarion based upon message fiels i have to decide which BAPI to be used and wht mapping and then post it to the same System
Any help will be highly rewarded
RegardsHi-
Yes it is possible you can use multimapping for mapping the interfaces.
To know more about multimapping see

please help - thanks!Hello Marek,
I suppose you are not planning to do any kinds of advanced config using several VLANs and multiple SSIDs so let's just make your configuration simple and working.
In short, you need to remove all references to VLAN 1 and to any subinterfaces possibly related to the VLAN 1. This means in particular (follow these steps in sequence):
Remove the Dot11Radio0.1 subinterface entirely
In the Dot11Radio0 section, remove the encryption vlan 1 mode ciphers tkip command
In the dot11 ssid ciscowifi section, remove the vlan 1 command
After performing these steps, make sure that the ssid ciscowifi and encryption mode commands are still present in the Dot11Radio0 configuration, and if not, reenter them.
Best regards,

Hello
I am wondering if it is possible to configure one ACE context to support both routed and bridge interface?
I would like to have a bridge-mode context but in the same time I would like to have a separated OOB interface for management.
If it is possible how they could interact to each other?
Thank you in advance for any answer

Hello
We've just tried to configure bridged and routed interfaces at the same time in the lab and we've had a problem.
When we added the def gw for the bridged config we noticed that we had an issue with the traffic src by the rservers in the routed config.
When we deleted the new def gw, the problem disappeared.
I am attaching the lab config.
When we added to it the following line
ip route 0.0.0.0 0.0.0.0 10.1.1.163
reals B1-B10 could not communicate to the outside world.
Do you know why it does not worked and what could we do to fix it ?
Thank you in advance.

Use two interfaces on the same network
Hello every one,
I actually starting to work on a cisco project. I'm a beginner on networking and cisco technologie.
For my project we use a router 2921.
We got two network:
- Network A: 192.198.0.X / 255.255.255.0 / Gateway 192.198.0.1
- Network B: 162.168.0.X / 255.255.0.0 / Gateway 162.168.0.1
Each network use switch, Switch A (connecting to network A) is connected to interface G0/0.
And Switch B (connecting to network B) is connected to interface G0/1.
Router well configured as:
- G0/0: ip address 192.198.0.1 255.255.255.0 (network A)
- G0/1: ip address 162.168.0.1 255.255.0.0 (network B)
Every think working fine.
The problem is with this one, we need to connect a computer on G0/2. This computer is configure as network A (192.198.0.10 / 255.255.255.0 and same gateway).
I can't configure G0/2 as 192.198.0.1 255.255.255.0 (network A), cause G0/0 use this adresse.
I can't put this computer on the switch A, my only physical possibilité is to connect him on G0/2.
We just need to use interface G0/0 and G0/2 as a switch on the router with the same gateway (192.198.0.1)
How can i connect this computeur? How can i configure two interfaces on the same network and same gateway?
Thanks youI would just put the PC on a different network, but if you really want it to be in the same network, you could use IRB to connect two of the interfaces on the router at layer 2.
Here is an example config for IRB:
interface FastEthernet0/0
bridge-group 1
interface FastEthernet0/1
bridge-group 1
bridge irb
interface BVI1
ip address 192.168.0.1 255.255.255.0
bridge 1 route ip
Notice that the physical ports do not have IP addresses on them, the IP for the subnet is on the BVI interface. -
My MacBook Pro, running 10.7.3, does not recognize when my iPhone and iPad are on the same network, thus it does not synch. Any ideas?
Try the basics first:
Change your router channel number. Most times this works & is all you have to do.
Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.

All my devices except my iPhone 4S can airprint. Only the 4s tells me no airprint printers found. I see no differences in the settings and I am on the same network as the printer. Like I said, two iPads and an iPhone 4 airprint like a champ!
Appreciate the suggestion and tried it, but still, no joy. I even had another iPhone brought into the network and it found the printer, no problem. It's just this one iPhone 4s. Sounds like a trip to the Genius Bar for me!

Timesten replication with multiple interfaces sharing the same hostname
Hi,
we have in our environment two Sun T2000 nodes, running SunOS 5.10 and hosting a TT server currently in Release 7.0.5.9.0, replicated between each other.
I would like to have some more information on the behavior of the replication w.r.t. network reliability when using two interfaces associated to the same hostname, the one used to define the replication element.
To make an example we have our nodes sharing this common /etc/hosts elements:
151.98.227.5 TBMAS10df2 TBMAS10df2-10 TBMAS10df2-ttrep
151.98.226.5 TBMAS10df2 TBMAS10df2-01 TBMAS10df2-ttrep
151.98.227.4 TBMAS9df1 TBMAS9df1-10 TBMAS9df1-ttrep
151.98.226.4 TBMAS9df1 TBMAS9df1-01 TBMAS9df1-ttrep
with the following element defined for replication:
ALTER REPLICATION REPLSCHEME
ADD ELEMENT HDF_GNP_CDPN_1 TABLE HDF_GNP_CDPN
CHECK CONFLICTS BY ROW TIMESTAMP
COLUMN ConflictResTimeStamp
REPORT TO '/sn/sps/HDF620/datamodel/tt41dataConflict.rpt'
MASTER tt41data ON "TBMAS9df1-ttrep"
SUBSCRIBER tt41data ON "TBMAS10df2-ttrep"
RETURN RECEIPT BY REQUEST
ADD ELEMENT HDF_GNP_CDPN_2 TABLE HDF_GNP_CDPN
CHECK CONFLICTS BY ROW TIMESTAMP
COLUMN ConflictResTimeStamp
REPORT TO '/sn/sps/HDF620/datamodel/tt41dataConflict.rpt'
MASTER tt41data ON "TBMAS10df2-ttrep"
SUBSCRIBER tt41data ON "TBMAS9df1-ttrep"
RETURN RECEIPT BY REQUEST;
On this subject moving from 6.0.x to 7.0.x there has been some changes I would like to better understand.
6.0.x reported in the documentation for Unix systems:
If a host contains multiple network interfaces (with different IP addresses),
TimesTen replication tries to connect to the IP addresses in the same order as
returned by the gethostbyname call. It will try to connect using the first address;
if a connection cannot be established, it tries the remaining addresses in order
until a connection is established.
Now On Solaris I don't know how to let gethostbyname return more than one interface (the documention notes at this point:
If you have multiple network interface cards (NICs), be sure that “multi
on” is specified in the /etc/host.conf file. Otherwise, gethostbyname will not
return multiple addresses).
But I understand this could be valid for Linux based systems not for Solaris.
Now if I properly understand the above, how was the 6.0.x able to realize the first interface in the list (using the same -ttrep hostname) was down and use the other, if gethostbyname was reporting only a single entry ?
Once upgraded to 7.0.x we realized the ADD ROUTE option was added to teach TT how to use different interfaces associated to the same hostname. In our environment we did not include this clause, but still the replication was working fine regardless of which interface we were bringing down.
My both questions in the end lead to the same doubt on which is the algorithm used by TT to reach the replicated node w.r.t. entries in the /etc/hosts.
Looking at the nodes I can see that by default both routes are being used:
TBMAS10df2:/-# netstat -an|grep "151.98.227."
151.98.225.104.45312 151.98.227.4.14000 1049792 0 1049800 0 ESTABLISHED

151.98.226.5.44949 151.98.226.4.14005 1049792 0 1049800 0 ESTABLISHED
Tried to trace with ttTraceMon but once I brought down one of the interfaces did not see any reaction on either node, if you have some info it would be really appreciated !
Cheers,
MikeHi Chris,
Thanks for the reply, I have few more queries on this.
1.Using the ROUTE CLAUSE we can use multiple IPs using priority level set, so that if highest priority level set in thr ROUTE clause for the IP is not active it will fall back to the next level priority 2 set IP. But cant we use ROUTE clause to use the multiple route IPs for replication simultaneously?
2. can we execute multiple schema for the same DSN and replication scheme but with different replication route IPs?
for example:
At present on my system, I have a replication scheme running for a specific DSN with stand alone Master-Subscriber mechanism, with a specific route IP through VLAN-xxx for replication.
Now I want to create and start another replication scheme for the same DSN and replication mechanism with a different VLAN-yyy route IP to be used for replication in parallel to the existing replication scheme. without making any changes to the pre-existing replication scheme.
for the above scenarios, will there be any specific changes respective to the different replication schema mechanism ie., Active Standby and Standalone Master Subscriber mechanism etc.,
If so what are the steps. like how we need to change the existing schema?
Thanks In advance.

Cant open external links and multiple instances of the same profile.
I have multiple firefox profiles.
I constantly have two profiles running at the same time.
I use microsoft outlook and see an external link, I click it wishing firefox to open it in the default or new browser. It does not and says "FIrefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system."
Firefox is running fine.
How can I open external links with a profile based setup?
Also, how can I open multiple instances of the same profile? I find that if I click and drag a tab to another monitor, it opens a new "instance" or browser window.You say
''I have multiple firefox profiles. <br />
I constantly have two profiles running at the same time. ''
So you will have discovered ''-no-remote'' Note NOT to use that on the default browser; profile, only on secondary profiles.
* http://kb.mozillazine.org/Profile_in_use#Common_causes
You will NOT be able to open multiple instances of the same profile, clone the profile if necessary.
If you are trying to run multiple Webmail accounts in one profile then you may well find the webmail is identifying and setting the user account that is opened. Use a Private Browsing window to get round that and open a second account.

Multiple Users Mounting the Same Network Share?
Hello, first time posting...
I'll cut right to my main question: Is it possible, on OS X v10.3.9, for multiple users to simultaneously connect to the same network share?
Here in my office, we have a single Mac that is used by multiple people throughout the day. It has two accounts on it, 'Communications' and 'Studio'. 'Communications' is an Admin account that is used by a co-worker who spends the most time on the Mac. He created the no-limitation 'Studio' account for the rest of us to use.
There is a certain Windows network share that we both frequently use. We've found that if one user connects to the share first, the other user will not have access to it; using 'Go -> Connect to Server' will result in the share being greyed out in the list, and the share will not show up in the Finder.
However, there is one way around it. If Studio connects to the share first and then Communications (the admin account) attempts to make a connection of it's own *through a shortcut on the dock*, then a 'clone' of the share will be created on Comm's desktop, with a "-1" after the name (though it might be some other number).
This may sound like I've answered my own question, but what I'm looking for is a way for the non-Admin account to access the share after the Admin account already has (so that we don't have to log-in and disconnect Communications everytime Studio needs to manage files on the share).
We have Thursby Software's DAVE installed on the Mac, but I'm not sure how it fits into all this.
Any thoughts, suggestions or advice?
Thanks.Bizarre. It turned out I could merge them, but only in to the mapped drive - L: - and only by explicitly clicking on the drive icon - if I typed L:\series in to dialog box it converted it back to \\nas\share\series... Not helpful.

Multiple printers on the same network problem
I have 2 HP OJ Pro 8600 printers and one HP OJ Pro 8500 Plus printer on the same network. My question is whether it is possible to change the network name of these printers so that it is easier to identify them.
The printers are in three different buildings so there is little stress to run around to find out where the print comes.Hi JObbern
If all the printers are on the same network you won't be able to change the network name on the printer.
You can change the name of the printer though on each computer. Depending on the operating system you are using, go to the printers window, right click and rename. Example Office1, Office 2.
If the option isn't available you can go to the printer window and add a printer and change the printer name through the wizard.
Hope that helps.

How do I merge multiple instances of the same network share?
In my (large) Lightroom 5.2 (Windows) library I have three instances of, essentially, the same network share (a Drobo NAS) which appear separately in the library.
One appears as Share (\\nas) L:, one as \\nas\Share and one as \\nas\share. The contents of the share are spread randomly across the three - so one might contain the folders series\event1, series\event4 and series\event5 and another series\event2, series\event3 and series\event6.
Is there an easy way to convince Lightroom that they're all the same physical location and merge them in the library? No amount of dragging, dropping, importing or synchronization seems to have had any effect so far!

Airplay from Multiple Sources on the Same Network
Hi,
I have a question that I was hoping someone could answer. I recently upgraded to iTunes 11 and bought a B&W A7 Airplay system. It works fine (bar the odd drop out). My question is, if I buy another A7 for another room and someone else in my house on the same network wants to airplay music from thier iOS device to that speaker whilst I am using iTunes to play music through the speaker in my room will that cause a problem?
In other words, can you have 2 different speakers recieving an airplay stream from 2 different devices?
Thanks in advance.Hi JObbern

Wired and wireless computers on the same network?
Here’s the scenario: I’ve got Verizon FIOS which comes with a modem with four Ethernet ports. I have an Airport Extreme plugged into the modem. There are six macs in the house (three desktops and three laptops) and they can all connect wirelessly although the signal fades in the living room and in my son’s room. I decided to run an Ethernet cable from the modem to the G5 that is in the living room and another one to my son’s room. Everything works fine but the “wired” computers are now no longer on the same network.
(At first I thought it was neat: if I was near the G5 and the signal from the Airport Extreme was weak, I could just hop onto the G5’s network (which has “Internet sharing” via airport enabled) but it’s become a nuisance because we always seem to be needing to change from one network to another: The computer connected to the printers is on Airport Extreme so I can’t print from the G5 unless I change the settings; if we’re in the bedroom connected to the Internet via the AirPort Extreme, we can’t access our iTunes music from the G5 without switching networks.)
I don’t know if there is a solution but it seems there should be.
I’d like to have two computers hard-wired and have all of them be part of the same home network. Is that possible?The solution is simple. Configure the AirPort Extreme base station (AEBS) so that the option to distribute IP addresses is DISABLED.
This will disable the AEBS's DHCP server and NAT. The net effect will be that anything connected to the AEBS's WAN port (anything connected to Verizon's router's LAN ports like your Ethernet computers) on the same subnet as the AEBS's LAN and wireless clients.
