community string is associated with SNMPv1 or SNMPv2 clients in the
SNMPv3 Communities table
Engine ID - The SNMPv3 engine ID. (Range: 10-64 hex digits,
◆
excluding a string of all 0's or all F's; Default: 800007e5017f000001)
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 local SNMP users will be cleared. You will
need to reconfigure all existing users.
SNMP Trap Configuration
Trap Mode - Enables or disables SNMP traps. (Default: Disabled)
◆
You should enable SNMP traps so that key events are reported by this
switch to your management station. Traps indicating status changes
can be issued by the switch to the specified trap manager by sending
authentication failure messages and other trap messages.
Trap Version - Indicates if the target user is running SNMP v1, v2c, or
◆
v3. (Default: SNMP v1)
Trap Community - Specifies the community access string to use when
◆
sending SNMP trap packets. (Range: 0-255 characters, ASCII
characters 33-126 only; Default: public)
◆ Trap Destination Address - IPv4 address of the management station
to receive notification messages.
Trap Destination IPv6 Address - IPv6 address of the management
◆
station to receive notification messages. An IPv6 address must be
formatted according to RFC 2373 "IPv6 Addressing Architecture," using
8 colon-separated 16-bit hexadecimal values. One double colon may be
used to indicate the appropriate number of zeros required to fill the
undefined fields.
Trap Authentication Failure - Issues a notification message to
◆
specified IP trap managers whenever authentication of an SNMP
request fails. (Default: Enabled)
Trap Link-up and Link-down - Issues a notification message
◆
whenever a port link is established or broken. (Default: Enabled)
Trap Inform Mode - Enables or disables sending notifications as
◆
inform messages. Note that this option is only available for version 2c
and 3 hosts. (Default: traps are used)
The recipient of a trap message does not send a response to the switch.
Traps are therefore not as reliable as inform messages, which include a
request for acknowledgement of receipt. Informs can be used to ensure
