We have experienced some errors that are preventing us from a full firmware update to several devices. The primary error occurs when attempting to make a TELENT connection. We are able to enter username and password, but then the session immediately hangs:
no display, no cursor, no keyboard responses.
The error occurs on multiple platforms while migrating from various versions of firmware to either v126.96.36.199 or v188.8.131.52. Here are a sampling of some of the affected devices:
Equip Model Current F/W New F/W
x650-24x 184.108.40.206 220.127.116.11
x650-24x 18.104.22.168 22.214.171.124
x460-48t 126.96.36.199 188.8.131.52
x460-24x 184.108.40.206 220.127.116.11
x450-48t 18.104.22.168 22.214.171.124
x450-48t 126.96.36.199 188.8.131.52
x350-48t 184.108.40.206 220.127.116.11
We're not sure if there is a problem with the XOS, setting, etc. The TELNET session hang DOES NOT OCCUR on all devices. We have successfully updated approx 75 already, but had to stop the update process once this error was discovered.
We have approximately 80 more devices to update, to which afterwards, they’ll have the SSH xmod installed. We appreciate any help or input you can offer.
