DELL N3000 User Manual

Configuring SNMP

This section provides information about the commands you use to manage 

and view SNMP features on the switch. For more information about these 

commands, see the 

Dell Networking N2000, N3000, and N4000 Series 

Switches CLI Reference Guide at 

.

To use SNMPv3, the switch must have engine ID. You can specify your own 

ID or use the default string that is generated using the MAC address of the 

switch. If the SNMPv3 engine ID is deleted, or if the configuration file is 

erased, then SNMPv3 cannot be used. Since the EngineID should be unique 

within an administrative domain, Dell recommends that you use the default 

keyword to configure the Engine ID.
the following guidelines are recommended:

• For standalone switches use the default keyword to configure the Engine 

ID.

• For a stack of switches, configure your own EngineID, and verify that is 

unique within your administrative domain.

Changing the value of SNMP EngineID has important side-effects. A user's 

password (entered on the command line) is converted to an MD5 or SHA 

security digest. This digest is based on both the password and the local engine 

ID. The command line password is then destroyed, as required by RFC 2274. 

Because of this deletion, if the local value of engineID changes, the security 

digests of SNMPv3 users will be invalid, and the users will have to be 

reconfigured.
Beginning in Privileged EXEC mode, use the following commands to 

configure an engine ID for SNMP.
