Avamar: snmpwalk command failing to Avamar server

When testing the Simple Network Management Protocol (SNMP) connectivity to an Avamar grid with the snmpwalk utility, it fails as follows: 

snmpwalk labavamar.company.com -v2c -cpublic .1.3.6.1.4.1.15597 

SNMPv2-SMI::enterprises.15597 = No Such Object available on this agent at this OID

The SNMP subagent is not running on the Avamar grid.

This can be verified by running the following:

admin@avamarlab:~/#: mccli server show-services

0,23000,CLI command completed successfully.

1. Start the SNMP subagent from the UI:

• • Management Console Server (MCS) Java UI:
    • Log in to the Avamar Administrator Console
    • Browse to Administration
    • Services Administration tab
    • Right-click snmp subagent, and select 'Start snmp subagent'
  • Avamar Web User Interface (AUI):
    • Log in to the Avamar AUI
    • Browse to Server
    • Services
    • Under Additional Services, Locate SNMP DAEMON
    • Click the 3-dots (kebab menu) and select Start
       

2. Retry the snmpwalk command.

For example:

snmpwalk labavamar.company.com -v2c -cpublic .1.3.6.1.4.1.15597 

The expected output from a successful snmpwalk command:

SNMPv2-SMI::enterprises.15597.1.1.2.3.1 = INTEGER: 2
SNMPv2-SMI::enterprises.15597.1.1.3.2.1 = INTEGER: 10

SNMP and snmpwalk:

Support for snmpwalk was introduced in Avamar 5.0 SP1 and is an SNMP application that uses SNMP GETNEXT requests to query a network entity for a tree of information.

The snmpwalk utility can be useful when troubleshooting SNMP issues or testing functionality after changing the configuration file /etc/snmp/snmpd.conf.

Issuing an snmpwalk query tests functionality by making a connection to the host using the public community string.
