vsiSessionDown

Module: CISCO-VSIMASTER-MIB

OID (symbolic): CISCO-VSIMASTER-MIB::vsiSessionDown

OID (numeric): 1.3.6.1.4.1.9.9.162.2.4

Node type: NOTIFICATION-TYPE

Description: This notification is generated when the vsiSessionState object transitions from any of unknown(1), configuring(2), or established(8) state to shutdownStarting(9) states. This notification is also generated when the vsiSessionState transitions from configuring(2) or established(8) state to the unknown(1) state.

The vsiSessionState object identifies the state and instance of the session, after the session has made the transition that caused the notification to be generated.

The agent will not generate this notification if the vsiSessionTrapEnable object is equal to 'false'.

Examples

Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):

snmptrap -v2c -c public <manager> '' CISCO-VSIMASTER-MIB::vsiSessionDown
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.9.9.162.2.4

Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):

snmptrapd -f -Lo -c /dev/null authCommunity log public

Example snmptrapd log entry:

zoo11-linux.zoo [UDP: [192.168.30.111]:58737->[192.168.30.10]:162]:
