Recommended Settings for NIC cards on call managers

Unanswered Question
Apr 21st, 2008

Hello there,


What is the Cisco recommendation for setting port speed on the servers.


I know on older servers that were 100 meg nic cards, you hard coded as 100meg full duplex on the call manager as well as the switchport


what is the official stance on the new 1gig server NIC, since you can't hardcode 1000 on an IOS. (unless i am missing something)


thanks!

thanks!


I thought thats what it was but couldn't find the link you had.


We are having some weird issues that we are trying to resolve and I wanted to cross off speed/ duplex as an issue.

Hi,


I've been asked to change the NIC on my CUCM servers from auto/auto to 100 full. We had new CUCM servers installed, and they were left on auto. The switch is set to 100/full and getting mismatch errors constantly.


Can someone tell me how to change the NIC speed? 7825H3 CUCM 6.1.3


Thanks so much,

Liz

Thanks Brandon,


I will try tomorrow morning as this:


"If you continue, this command causes a temporary loss of network connections while the NIC gets reset. Do you want to continue ?"


leads me to believe the phones will reset. I can't do this during business hours. Do you agree?

Your phones will not necessarily reset, but I would recommend doing this after hours.

Thanks again Brandon,


I don't make changes via CLI and I'm super nervous. I ran the show command and got:


admin:Auto enabled, Half, 100MB/s


I need to know what to type to change to 100/full without auto.


I've know this much:


set network nic eth0


but don't know the rest.


Can you help?

The command would be:


set network nic eth0 auto dis speed 100 duplex full


Hope this helps.

Thanks Brandon,


I made the changes this morning, without dropping the phones. I couldn't type the whole line, but had to do each alone. But, they took and I'm happy.


Thanks again and sorry for hijacking this tread!
