I have 6509 with SUP2 and CATOS 8.1.3 and IOS 12.1(22)E2 and I'm running Single router mode. I have started to see this strange problem when I can no longer access to active router by session 16, I get the error
session: Unable to tunnel to Router-16 (57)" I had to reboot the standby to make it work. I don't want to reboot this time. anyone seen this?
Can you console into the MSFC using "switch console 16" and then verify that the vty lines are in use?
You can issue the command "sh line" which will probably show them all in use. You can clear the lines your want by issuing the command "clear line vty #" from an enable prompt. If you want to enable additional vty lines for telnet, you can issue the command "line vty 5 8" in global config mode. This will give you 4 more vty lines if you so desire.
Exec timeout is configured but I suspect that the lines are still occupied (not sure why) but since I'm not able to get into active router mode and if I clear the line in standby router it clears the line only for standy router (am I right?) I guess my last option is to travel to the side and do switch console 16. DO you have any other suggestion that it can be done remotely?
