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

Giuseppe

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
