Command Usage
â—† Local users (i.e., the command does not specify a remote engine identifier)
must be configured to authorize management access for SNMPv3 clients, or to
identify the source of SNMPv3 trap messages sent from the local switch.
â—† Remote users (i.e., the command specifies a remote engine identifier) must be
configured to identify the source of SNMPv3 inform messages sent from the
local switch.
â—† The SNMP engine ID is used to compute the authentication/privacy digests
from the password. You should therefore configure the engine ID with the
snmp-server engine-id command before using this configuration command.
â—† Before you configure a remote user, use the snmp-server engine-id command
to specify the engine ID for the remote device where the user resides. Then use
the snmp-server user command to specify the user and the IP address for the
remote device where the user resides. The remote agent’s SNMP engine ID is
used to compute authentication/privacy
digests from the user’s password. If the
remote engine ID is not first configured,
the snmp-server user command
specifying a remote user will fail.
â—† SNMP passwords are localized using the engine ID of the authoritative agent.
For informs, the authoritative SNMP agent is the remote agent. You therefore
need to configure the remote agent’s SNMP engine ID before you can send
proxy requests or informs to it.
