Configuring SNMP (CLI)
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 EMC Networking N1100-ON, N1500, N2000,
N2100-ON, N2200-ON, N3000E-ON, N3100-ON, and N3200-ON Series

Configuring the SNMPv3 Engine ID
To use SNMPv3, the switch must have an engine ID configured. The default
string that is generated using the MAC address of the switch can be used, or
another value can be specified. 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 for
stand-alone switches.
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.
Use the following commands to configure an engine ID for SNMP.
