Description

SNMP process may crash when polling Ethernet Connectivity Fault Management protocol statistics using OID - 1.3.111.2.802 (lan-man-stds).

 

Symptoms

The router should have at least below CFM configuration:

# set chassis network-services enhanced-ip
# set protocols oam ethernet connectivity-fault-management maintenance-domain BNG level 2
# set protocols oam ethernet connectivity-fault-management performance-monitoring hardware-assisted-keepalives enable

Solution

When the OID - 1.3.111.2.802 (lan-man-stds) is polled by the SNMP server, the SNMPD process crashes with coredump.

Workaround is the exclude this OID in a SNMP view and associate the view with the community string. 

Example: 

set snmp view test-view oid .1 include

set snmp view test-view oid .1.3.111.2.802 exclude

set snmp community public view test-view

set snmp community public authorization read-only
