bsLstGroupOperStateChanged

Module: BAY-STACK-LINK-STATE-TRACKING-MIB

OID (symbolic): BAY-STACK-LINK-STATE-TRACKING-MIB::bsLstGroupOperStateChanged

OID (numeric): 1.3.6.1.4.1.45.5.43.0.2

Node type: NOTIFICATION-TYPE

Description: This notification is generated when the operational status of a link-state tracking group changes due to an interface status change. For example, when the last interface of an link-state tracking group becomes down, the operational status of the group changes to down.

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> '' BAY-STACK-LINK-STATE-TRACKING-MIB::bsLstGroupOperStateChanged
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.45.5.43.0.2

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:
