Configuring SNMP

Configuring SNMP

To configure SNMP for the Nortel SNAS network, access the SNMP menu
by using the following command:

/cfg/sys/adm/snmp

From the SNMP menu, you can configure and manage the following:

•

general settings for SNMP management of the cluster (see

“Configuring SNMP settings” (page 325)

)

•

parameters in the standard SNMPv2 MIB (see

“Configuring the SNMP

v2 MIB” (page 326)

)

•

monitor, control, and trap community names (see

“Configuring the

SNMP community” (page 327)

)

•

SNMPv3 users (see

“Configuring SNMPv3 users” (page 328)

)

•

SNMP managers (see

“Configuring SNMP notification targets” (page

331)

)

•

SNMP monitors and events (see

“Configuring SNMP events” (page

332)

)
