I thought I will ask the question here as the problem switches that I have is very old.
A client of ours have a few hundred B2G switches deployed.
Recently these switches started showing the same problematic symptoms:
The Management interface freezes.
This results in no SNMP, SSH or console access.
We have also seen that all the devices that is connected to the switch continues to operate.
When you connect a new device it does not get an IP, as if the MAC address table does not populate.
The switch is running the last released firmware.
The only config that was changed over the past 6 months was a change in SNMP from v2 to v3
We have noticed that all the switches displaying these symptoms is running for more than 700 Days.
Anyone else seen this (Trying my luck)
