unacknowledgedTCN
Module: TIMETRA-SDP-MIB
OID (symbolic): TIMETRA-SDP-MIB::unacknowledgedTCN
OID (numeric): 1.3.6.1.4.1.6527.3.1.3.4.5.0.8
Node type: NOTIFICATION-TYPE
Description: The unacknowledgedTCN notification is generated when a TCN sent towards the root bridge on the root port (SAP or SDP binding) has not been acknowledged within the allowed time. A portion of the spanning tree topology may not have been notified that a topology change has taken place. FDB tables on some devices may take significantly longer to represent the new distribution of layer-2 addresses. Examine this device and devices towards the root bridge for STP issues.
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> '' TIMETRA-SDP-MIB::unacknowledgedTCN snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.6527.3.1.3.4.5.0.8
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]:58570->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (353010890) 40 days, 20:35:08.90 SNMPv2-MIB::snmpTrapOID.0 = OID: TIMETRA-SDP-MIB::unacknowledgedTCN
SNMPv3 example:
snmptrap -v3 -l authPriv -u snmpv3user -a SHA -A "AuthPass1" -x AES -X "PrivPass1" <manager> '' TIMETRA-SDP-MIB::unacknowledgedTCN
