newRootBridge
Module: ALCATEL-IND1-TIMETRA-SERV-MIB
OID (symbolic): ALCATEL-IND1-TIMETRA-SERV-MIB::newRootBridge
OID (numeric): 1.3.6.1.4.1.6527.3.1.3.4.5.0.7
Node type: NOTIFICATION-TYPE
Description:
The newRootBridge notification is generated when this bridge has been elected as the new root bridge. A new root bridge creates a new spanning tree topology and may denote loss of customer access or redundancy. Check the new topology against the provisioned topology to determine severity of connectivity loss.
What is newRootBridge?
A critical alert that fires when this switch becomes the new root of the spanning tree. Indicates the network topology just changed and could mean redundancy or customer connectivity was lost. A NOC operator receiving this alarm would immediately investigate whether the topology change was planned or signals a network failure.
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> '' ALCATEL-IND1-TIMETRA-SERV-MIB::newRootBridge snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.6527.3.1.3.4.5.0.7
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
