Configuring Mac Threshold Notification Traps - Cisco Catalyst 3750-X Software Configuration Manual

Chapter 7 Administering the Switch
Beginning in privileged EXEC mode, follow these steps to configure the switch to send MAC
address-move notification traps to an NMS host:
Command
Step 1
configure terminal
snmp-server host host-addr {traps | informs}
Step 2
{version {1 | 2c | 3}} community-string
notification-type
Step 3 snmp-server enable traps mac-notification
move
Step 4 mac address-table notification mac-move
Step 5
end
Step 6
show mac address-table notification mac-move
show running-config
Step 7
copy running-config startup-config
To disable MAC address-move notification traps, use the no snmp-server enable traps
mac-notification move global configuration command. To disable the MAC address-move notification
feature, use the no mac address-table notification mac-move global configuration command.
This example shows how to specify 172.20.10.10 as the NMS, enable the switch to send MAC address
move notification traps to the NMS, enable the MAC address move notification feature, and enable traps
when a MAC address moves from one port to another.
Switch(config)# snmp-server host 172.20.10.10 traps private mac-notification
Switch(config)# snmp-server enable traps mac-notification move
Switch(config)# mac address-table notification mac-move
You can verify your settings by entering the show mac address-table notification mac-move privileged
EXEC commands.

Configuring MAC Threshold Notification Traps

When you configure MAC threshold notification, an SNMP notification is generated and sent to the
network management system when a MAC address table threshold limit is reached or exceeded.
OL-21521-01
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 move notification traps
to the NMS.
Enable the MAC address move notification feature.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
