SPECIFYING A REMOTE
ENGINE ID
Use the Administration > SNMP (Configure Engine - Add Remote Engine)
page to configure a engine ID for a remote management station. To allow
management access from an SNMPv3 user on a remote device, you must
first specify the engine identifier for the SNMP agent on the remote device
where the user resides. The remote engine ID is used to compute the
security digest for authentication and encryption of packets passed
between the switch and a user on the remote host.
COMMAND USAGE
◆ 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. (See "Configuring
Remote SNMPv3 Users" on page 243.)
PARAMETERS
These parameters are displayed:
◆ Remote Engine ID – The engine ID can be specified by entering 9 to
64 hexadecimal characters (5 to 32 octets in hexadecimal format). If
an odd number of characters are specified, a trailing zero is added to
the value to fill in the last octet. For example, the value “123456789” is
equivalent to “1234567890”.
◆ Remote IP Host – The IP address of a remote management station
which is using the specified engine ID.
WEB INTERFACE
To configure a remote SNMP engine ID:
1. Click Administration, SNMP.
2. Select Configure Engine from the Step list.
3. Select Add Remote Engine from the Action list.
4. Enter an ID of a least 9 hexadecimal characters, and the IP address of
the remote host.
5. Click Apply
