Purpose
Enter global configuration mode.
Specify the recipient of the trap message.
•
For host-addr, specify the name or address of the
NMS.
•
Specify traps (the default) to send SNMP traps
to the host. Specify informs to send SNMP
informs to the host.
Specify the SNMP version to support. Version 1,
•
the default, is not available with informs.
For community-string, specify the string to send
•
with the notification operation. Though you can
set this string by using the snmp-server host
command, we recommend that you define this
string by using the snmp-server community
command before using the snmp-server host
command.
For notification-type, use the mac-notification
•
keyword.
Enable the switch to send MAC address traps to the
NMS.
Enable the MAC address notification feature.
Enter the trap interval time and the history table size.
•
(Optional) For interval value, specify the
notification trap interval in seconds between
each set of traps that are generated to the NMS.
The range is 0 to 2147483647 seconds; the
default is 1 second.
(Optional) For history-size value, specify the
•
maximum number of entries in the MAC
notification history table. The range is 0 to 500;
the default is 1.
Enter interface configuration mode, and specify the
interface on which to enable the SNMP MAC
address notification trap.
Enable the MAC address notification trap.
•
Enable the MAC notification trap whenever a
MAC address is added on this interface.
Enable the MAC notification trap whenever a
•
MAC address is removed from this interface.
Return to privileged EXEC mode.
