HP Procurve 5406ZL - Network Issue.

[10101010]

Advice welcome

 

I currently use a HP Procurve 5406zl as my core switch which has been working solidly over the past few years. However, yesterday was the 2nd time in 9 months I had no other option than to completely power down the switch to resolve the network issues we were experiencing - clients were unable to recieve dhcp addresses from DC's, which would then have a knock on affect for other services.

 

In my HPE management software the switch was showing as 'normal' and no 'major' or 'warnings' highlighted , but I was unable to telnet into the core switch which left me little option other than to power down the switch. The moment the switch is backup, normal service resumes and I can telnet back in.

 

Any advice on troubleshooting would be appreciated.

 

I have been running the same verion of firmware for a number of years now.

I'd look at a firmware update after looking at the release history notes between your current one and the latest. HP are pretty good at documenting what each release fixes, you can find these at: https://h10145.www1.hpe.com/support/SupportLookUp.aspx don't forget though you have a lifetime warranty on these so you can always log a job with HPE before doing anything

Also worth checking for packet storms/loops around the place. We've had these eventually work our 5406zl into a strop and refuse to respond. Tracing and pulling the loops brings it back.
