[c-nsp] Cisco VSS monitoring through Syslog/SNMP-traps

[Sukumar Subburayan (sukumars)]

For Complete VSL failure, we have SNMP trap, that can be configured using:

vss(config)#snmp-server enable traps vswitch ?
  vsl  Enable SNMP Virtual Switch Link (VSL) notification
 
For Active supervisor failure, you can monitor the following syslog message:

PFREDUN-SW2_SPSTBY-6-ACTIVE: Initializing as Virtual Switch ACTIVE processor

If the message comes from 'SW2' it means that previous active(SW1) went down.

For standby supervisor failure, the VSL link will go down, as entire standby is down. So, you could use the 
VSL link trap. 

Additionally following syslogs are printed on the active, when standby goes down:

%VSLP-SW2_SP-2-VSL_DOWN:   All VSL links went down while switch is in ACTIVE role

or this:

%PFREDUN-SW2_SP-6-ACTIVE: Standby supervisor removed or reloaded, changing to Simplex mode

Hi,

Does anybody know what syslog messages are supposed to be sent when a VSS failover occurs?
Would it be easier to monitor it through SNMP traps? In that case what kind of traps should I enable and what are the corresponding OID to handle from the server?
The main idea is to detect any failures within the VSS domain. I identified
3 types of failures I would need to detect thanks to the syslog messages or SNMP-traps. Then, corresponding alarms will be generated. Here they are:
-> Active Supervisor Engine Failure (=Active Virtual Switch Chassis 
-> Failure) Hot-standby Supervisor Engine Failure (=Standby Virtual 
-> Switch Chassis
Failure)
-> Complete VSL Failure (Dual Active)

If someone knows or identified syslog messages and/or SNMP traps corresponding to each of these three failures, could you please get back to me with these informations?
Many thanks.

Anthony
