The SNMP agent provides read-only access in this release.
Procedure
-
Enable the SNMP agent on either the management interface, or the switch data ports, with the command
snmp-server vrf
. For example, use the command
snmp-server vrf mgmt
to enable SNMP on the management interface. Use the command
snmp-server vrf default
to enable SNMP on the
default
vrf which is initially assigned to all data ports.
-
Set the system contact, location, and description for the switch with the commands
snmp-server system-contact
,
snmp-server system-description
, and
snmp-server system-location
.
-
If required, change the default SNMP port on which the agent listens for requests with the command
snmp-server agent-port
.
-
By default, the agent uses the community string
public to protect access through SNMPv1/v2c. Set a new community string with the command
snmp-server community
.
-
Configure the trap receivers to which the SNMP agent will send trap notifications with the command
snmp-server host
.
-
To support SNMP v3 users, define one or more SNMPv3 contexts with the command
snmpv3 context
, then define credentials for one or more users with the command
snmpv3 user
. Finally, associate defined users with an SNMPv3 context with the command
snmpv3 user context
.
-
Review your SNMP configuration settings with the commands
show snmp agent-port
,
show snmp community
,
show snmp system
,
show snmpv3 context
,
show snmp trap
,
show snmp vrf
,
show snmpv3 users
and
show tech snmp
.
NOTE: Configuring
snmpv3 informs
is not supported.
