A PIM neighbor relationship was lost.

Alarm ID	Alarm Severity	Alarm Type
1.3.6.1.2.1.157.0.1	Major	communicationsAlarm(2)

Name	Meaning
oid	Indicates the MIB object ID of the alarm.

NbrAddrType	Indicates the inetAddressType of neighbor address. The value can be: 1: IPv4 address 2: IPv6 address
NbrAddr	Address of a neighbor
NbrUpTime	Time elapsed since a neighbor relationship was established

The PIM neighbor relationship will be interrupted and multicast services will be affected.

Cause 1:

The timer of a PIM neighbor expired.

Cause 2:

The switch received a Hello packet with the Holdtime field of 0.

Run the display pim interface interface-type interface-number command on a PIM neighbor. Check whether PIM is enabled on the interface connecting the PIM neighbor to the local switch.
- If PIM is enabled on the interface, go to step 3.
- If PIM is disabled on the interface, go to step 2.
Run the pim dm or pim sm command to enable PIM on the interface connecting the PIM neighbor to the local switch. Run the display pim neighbor neighbor-address command on the PIM neighbor to view the PIM neighbor relationship status.
- If the PIM neighbor relationship is established, go to step 6.
- If the PIM neighbor relationship is not established, go to step 3.
Run the display ip routing-table ip-address command on the PIM neighbor to view the route to the local switch.
- If the route is reachable, go to step 5.
- If the route is unreachable, go to step 4.
Rectify the route fault to clear the trap. After the route becomes reachable, run the display pim neighbor neighbor-address command on the PIM neighbor to view the PIM neighbor relationship status.
- If the PIM neighbor relationship is established, go to step 6.
- If the PIM neighbor relationship is not established, go to step 5.
Collect alarm information and configuration information, and then contact technical support personnel.
