Description
Use the snmp-agent trap if-mib link extended command to extend the standard linkUp/linkDown traps defined in RFC. An extended linkUp/linkDown trap is the standard linkUp/linkDown trap defined in RFC appended with the interface description and interface type information.
Use the undo snmp-agent trap if-mib link extended command to restore the default.
By default, standard linkUp/linkDown traps defined in RFC are used.
A standard linkUp trap is in the following format:
#Apr 24 11:48:04:896 2015 Sysname IFNET/4/INTERFACE UPDOWN: Trap 1.3.6.1.6.3.1.1.5.4<linkUp>: Interface 983555 is Up, ifAdminStatus is 1, ifOperStatus is 1
An extended linkUp trap is in the following format:
#Apr 24 11:43:09:896 2015 Sysname IFNET/4/INTERFACE UPDOWN: Trap 1.3.6.1.6.3.1.1.5.4<linkUp>: Interface 983555 is Up, ifAdminStatus is 1, ifOperStatus is 1, ifDescr is GigabitEthernet1/0/1, ifType is 6
A standard linkDown trap is in the following format:
#Apr 24 11:47:35:224 2015 Sysname IFNET/4/INTERFACE UPDOWN: Trap 1.3.6.1.6.3.1.1.5.3<linkDown>: Interface 983555 is Down, ifAdminStatus is 2, ifOperStatus is 2
An extended linkDown trap is in the following format:
#Apr 24 11:42:54:314 2015 Sysname IFNET/4/INTERFACE UPDOWN: Trap 1.3.6.1.6.3.1.1.5.3<linkDown>: Interface 983555 is Down, ifAdminStatus is 2, ifOperStatus is 2, ifDescr is GigabitEthernet1/0/1, ifType is 6
The format of an extended linkup/ linkDown trap is the standard format followed with the ifDescr and ifType information, facilitating problem location.
When this command is configured, the device sends extended linkUp/linkDown traps. If the extended messages are not supported on NMS, the device may not be able to resolve the messages.
