Looking through the firmware release notes, it looks like this was a known issue, that http/https was not following the exec-timeout setting. The command # ip http timout-policy, was added in 6.2.6.6. I would test altering the timeout setting using the command # ip http timeout-policy.  Example from release notes: console(config)#ip http timeout-policy idle 3600 life 86400 Let us know if this works.
All my N4032 and N3024 switches with 6.2.7.2 firmware automaticlly break http and https session after ~180 seconds of inactivity. Commands:line telnetexec-timeout xdon't workDoes anyone have a similar experience?Is this a known issue?
Auto Logout after 180 sec. inactivity (http and https)
