    I have a problem: management crash issues at Enterasys B5G124-48

     

    The switch still works, but only the management crashes. I can connect via telnet and ssh, but on the Netsight Console its still out. Can anyone help me to solve this problem?

    There´s no problem about the temperature or system process.

    Is it marked as down or is it red because of critical alarms e.g. SNMP contact lost?

    Is it a stack?

    Use the command “show snmp counter”, does this give any hint? e.g. usmStatsWrongDigst, usmStatsUnknownEngineId?

    Can you try to set the SNMP settings on the switch again, even though they appear to be correct?

    Best regards

    Stefan, thanks for your help! Here below my answers:

     

    Is it marked as down or is it red because of critical alarms e.g. SNMP contact lost?

    Answer: Sometimes ate netsight console lost contact, and send a critical alarm.

    Is it a stack?

    Answer: No.

    Use the command “show snmp counter”, does this give any hint? e.g. usmStatsWrongDigst, usmStatsUnknownEngineId?

    Answer: I´ll collect some logs to check if the count of these stats is increasing or not.

     

    Can you try to set the SNMP settings on the switch again, even though they appear to be correct?

    Answer: I tried twice time and still crashing. The management comes back without any action.

     

    Best regards,

    Do you have the possibility to upgrade the firmware as it is 7 years old? Whats your NetSight/XMC version?

    In addition:

    Use the command “show snmp counter”, does this give any hint? e.g. usmStatsWrongDigst, usmStatsUnknownEngineId?

    Answer: Both are increasing from time to time

    Well, this is even older than your switch firmware. :)  (current Version is NetSight 8.5)

    Is this the only switch that has this problem? Are others working fine? Do they maybe have another firmware?

    If I understand it correctly, this problem only occurs sometimes and is not always the case?

    Answer: Yes, it´s the only equipment. Most of my equipments have this version of firmware.

    Answer: The problem occurs sometimes, but data and voice still work, just the management that fails.
