sw0657840StpTopologyChanged

Module: PRIVATE-SW0657840-MIB

OID (symbolic): PRIVATE-SW0657840-MIB::sw0657840StpTopologyChanged

OID (numeric): 1.3.6.1.4.1.5205.2.9.1.20.102

Node type: NOTIFICATION-TYPE

Description: Send the trap when RSTP determines a port should enter the FORWARDING state (a topology change occurs). The OID value is the ifIndex of the port that produces the topology change.

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> '' PRIVATE-SW0657840-MIB::sw0657840StpTopologyChanged
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.5205.2.9.1.20.102

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]:58497->[192.168.30.10]:162]:
