We currently have ntp sevrers defined in network as ip address, we need to change ntp server ip address and I though I would configure them in router and switches as their DNS name and then change the ip address in the server. When I go do that it shows still ntp with its ip address instead of a name and in Cisco 3560 it doesn't like ntp server <name>.
Any idea what could be wrong. I have dns server and ip domain-name is already defined.
No, this is not what I meant. I already have ntp and dns sever definied in my touers and switches. I need to replace ntp sevrer ip address configuration with its name for example I have
ntp server 10.1.1.1 and I need to replace this 10.1.1.1 with time1.mydomain.com and Cisco 3560 doesn't like this command. I have Cisco 6509 with CatOS, they take the command but when i do show config it show ntp server 10.1.1.1 instead of ntp time1.mydomain.com
That's because IOS resolves the name to the IP address and then stores the IP in the config. No way to change that. Your 3560 probably doesn't have 1) name servers defined or 2) has "no ip domain-lookup" configured.
