wwpLeosMstpSelfLoopNotification

OID (symbolic): WWP-LEOS-MSTP-MIB::wwpLeosMstpSelfLoopNotification

OID (numeric): 1.3.6.1.4.1.6141.2.60.37.0.5

Node type: NOTIFICATION-TYPE

Description: A wwpLeosMstpSelfLoopNotification is sent whenever device detects same cable connected to a port in a loop back. This determination is made by comparing the layer-2 address of the received frame with that of the bridge. This occurs before the frame data reaches the MSTP state machine logic. Also if loop-back blocking is enabled on the device then mstp will block this port (self disable).

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> '' WWP-LEOS-MSTP-MIB::wwpLeosMstpSelfLoopNotification
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.6141.2.60.37.0.5

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:
