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.
Beginning in privileged EXEC mode, follow these steps to configure the switch to send MAC address
table threshold notification traps to an NMS host:
Command
Step 1
configure terminal
Step 2
snmp-server host host-addr {traps | informs} {version {1
| 2c | 3}} community-string notification-type
Step 3
snmp-server enable traps mac-notification threshold
Step 4
mac address-table notification threshold
Step 5
mac address-table notification threshold [limit
percentage] | [interval time]
Step 6
end
Step 7
show mac address-table notification threshold
show running-config
Step 8
copy running-config startup-config
OL-26520-01

Managing the MAC Address Table
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.
(Optional) For limit percentage, specify the
•
percentage of the MAC address table use; valid
values are from 1 to 100 percent. The default is
50 percent.
(Optional) For interval time, specify the time
•
between notifications; valid values are greater
than or equal to 120 seconds. The default is 120
seconds.
