Configuring SNMPv3 Management Access
To configure SNMPv3 management access to the switch, follow these steps:
1.
If you want to change the default engine ID, it must be changed first before
configuring other parameters.
2.
Specify read and write access views for the switch MIB tree.
3.
Configure SNMP user groups with the required security model (i.e., SNMP v1,
v2c or v3) and security level (i.e., authentication and privacy).
4.
Assign SNMP users to groups, along with their specific authentication and
privacy passwords.
Setting the Local Engine ID
An SNMPv3 engine is an independent SNMP agent that resides on the switch. This
engine protects against message replay, delay, and redirection. The engine ID is
also used in combination with user passwords to generate the security keys for
authenticating and encrypting SNMPv3 packets.
A local engine ID is automatically generated that is unique to the switch. This is
referred to as the default engine ID. If the local engine ID is deleted or changed, all
SNMP users will be cleared. You will need to reconfigure all existing users.
A new 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, entering the
value "123456789" sets the engine ID as "1234567890".
