I have several IOS based switches that when I issue the "show cdp nei detail" command I get a Device ID that includes the domain name of the device. I can't for the life of me get rid of the domain name (I don't want it to show). I've removed all references to any domain name from the switch config yet it still shows. Any idea how the domain name is being attached to the Device ID name when doing a show cdp neig?
You need to make sure NOT to use "ip domain-name my.domain.com" form of the command as this will append the domain name to the DeviceID. I use the "ip domain-list my.domain.com" form instead. Also, you need to pay SPECIAL ATTENTION to VOIP gateways and Call Manager configs. For VOIP gateways such as 2851's using MGCP the Call manager will configure the gateway with whatever name you gave it originally. So if you change (remove) the domain name then you'll need to make sure the call manager's config is also changed within CallManager otherwise the callmanager will unregister the gateway.
Jack, as far as I'm aware this is not documented on cisco.com anywhere however I did find a bug associated to this problem. Later versions of code should have this fixed.
Thanks a lot for your clarification. Could you advise is there any bug ID for this issue ? In some support activities, we require vendor info. to support our solution, so if there is a bug ID then it is easier for us to search. Many Thx.
The bug numbers include: CSCsc41856 and CSCee50559. Note that the first one is a duplicate of the second, but it's the only one externally visible to you guys through the Bug system.
