community string for authentication. Access to the switch from clients using SNMPv3 provides
additional security features that cover message integrity, authentication, and encryption; as
well as controlling user access to specific areas of the MIB tree.
This tab provides global parameters, views, group profile, group membership, communities
and notification recipient functions for the switch system.
SNMP Tab—Global Parameters
The Global Parameters screen includes configuration settings for the local and remote engine
identifiers used by SNMPv3, and enabling or disabling trap messages sent to designated
management stations.
SNMPv3
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 1 to 26 hexadecimal characters. If less than 26
characters are specified, trailing zeroes are added to the value. For example, the value "1234" is
equivalent to "1234" followed by 22 zeroes.
User Default—Check this box to restore the default local engine ID.
