session: Unable to tunnel to Router-15 (57)

Ten minutes ago I had a problem on a Catalyst 6500 with a couple of supervisor II with MSFC.

Module 15 and 16 are in SRM and the 15 was in active state and the 16 in standby, but (very strange), when I tried to connect the first one, from the L2 module, I received this message:

C6500> (enable) sess 15

Trying Router-15...

session: Unable to tunnel to Router-15 (57)

The system logs doesn't say nothing while the "show modules" saw:

C6500> (enable) sh module

Mod Slot Ports Module-Type Model Sub Status

--- ---- ----- ------------------------- ------------------- --- --------

1 1 2 1000BaseX Supervisor WS-X6K-S2U-MSFC2 yes ok

15 1 1 Multilayer Switch Feature WS-F6K-MSFC2 no ok

2 2 2 1000BaseX Supervisor WS-X6K-S2U-MSFC2 yes standby

16 2 1 Multilayer Switch Feature WS-F6K-MSFC2 no standby

It seems that there was some problems to the first msfc, so I reseted the module 15 and then the modules started to work properly.

On the L2 I'm using the 7.6.1 while on the msfc the 12.1(13)E8.

Any ideas?

thanks

Are you able to telnet to the router from another device using one of the IP addresses configured on the MSFC's VLAN interfaces?

You should also be able to access it through the console port using the "switch console" command.

once you get in via telnet or switch console, try the following:

1. switch console into the msfc

2. Do a show run, and look under the vty statement at the end of the sh run

It should read like this:

line vty 0 4

login

transport input all

If you do not have the "transport input all", please do the following:

LTD-18-3-MSFC(config)#line vty 0 4

LTD-18-3-MSFC(config-line)#transport input all

This should hopefully resolve the problem for you.
