ENABLE SNMP COMMUNITY (SEC)

Syntax

ENABLE SNMP COMMUNITY=name [ TRAP ]

Description The ENABLE SNMP COMMUNITY command enables a SNMP community for access or

enables the generation of trap messages for the community. This command does not,

however, allow the user to enable the community and trap generation at the same time.

In order to enable both the community and trap, the user must run the command twice;

once with the TRAP parameter and another time without. The following describes the

behavior of the command:

- ENABLE SNMP COMMUNITY=comm_name command allows access to the device

through the specified community. If the community was created with READ-ONLY

access, the user can perform read operations on any accessible and supported SNMP MIB

variable. A community has READ-ONLY access by default. If the community was created

with READ-WRITE access, the user is allowed to perform SNMP SETs as well GETs.

- ENABLE SNMP COMMUNITY=public TRAP command enables trap generation for the

community. The device only generates traps if one or more communities are enabled for

trap generation.

Note: Since community and trusted host checks are the only security mechanisms avail-

able in SNMPv1/SNMPv2c, a READ-WRITE community must NOT be trap enabled. Since

the community acts as a crude password and the community name is included in the trap,

the trap would reveal how to access the device for configuration changes. Typically only

one community is trap-enabled on a device unless a user intends to use the trap commu-

nity as a trap filter on the Network Management Station.

Options The following table gives the range of values for each option that can be specified with

this command and a default value (if applicable).
