unable to telnet to 4948 switch from a routed network
03-03-2009 11:38 PM
Hello Venoy,
can you ping the 4948 management ip address ?
if you cannot ping it, a default gateway can be missing on it.
if you can ping it but telnet access is not possible it is possible that a filter is configured under the line vty to allow telnet only from specific ip addresses/subnets
something like
line vty 0 15
access-class 11 in
access-list 11 permit 10.10.10.0 0.0.0.255
this allows telnet only from 10.10.10.0/24
third option: the device allows only ssh sessions and not telnet.
Hope to help

Hi Giuseppe,
Thanks for your reply.
I am able to ping the device and also telnet the device locally.
There is no filter configured on the vty.
The default gateway is also set.
But i ma not able to access the swith either ping or telnet from a routed network.

Can you ping the default-gateway from the switch ?
If you have no filters and you can ping/telnet locally then it is a routing issue. What is the default-gateway device and
1) does it have a route back to your source IP address that you are trying to telnet to
2) could you post ouput of a traeroute from your PC to the switch

Check if you address is Nated through the network.
Also check tht telnet is filtered accross dhe network
