Cannot ping hostname ....

Hi,

I cannot ping using hostname but it works when I ping using IP ... The below is the output that I get.

Translating "switch1"

% Unrecognized host or address, or protocol not running.

I have the following commmands in the 3550 switch ...

ip domain-name aaa.bbb.com

ip name-server 190.x.100.100

ip name-server 190.x.100.101

Anyone know what could be the possible cause of this ?

Thanks a bunch ...

Re: Cannot ping hostname ....

Hi

Do you have an entry for switch1 in your DNS servers 190.170.100.100 & 101 ?

The other way to do this is to create a local host entry on your 3550 eg:

ip host switch1 192.168.5.1

Re: Cannot ping hostname ....

problem indicates that DNS server and domain configured is not able to resolve IP address of the device you are trying to access.

you can define a static host name-to-address mapping in the host cache, use the ip host global configuration command.

configure below command and then check if you are able to ping using hostname or not.

ip host switch1

HTH, rate if it does ...

Hi

I think your missing the command "ip domain-lookup" in global configuration mode.

Thanks
