Monitoring MAC address movement
Configuring an interval for collecting MAC address move
notifications
To configure an interval for collecting statistical data about MAC address moves, enter the
mac-movement notification interval-history command at the privileged EXEC level. This command
enables a corresponding SNMP trap. This history includes statistical information such as the
number of MAC addresses that move over the specified period, the total number of MAC address
moves, which MAC addresses have moved, and how many times a MAC address has moved.
The software places an upper limit on the number of MAC addresses for which MAC
address-specific data is reported. This limit is necessary to do this because it is not possible to
report on all MAC addresses when many move.
The following example configures a history interval of 10 seconds.
To disable the feature and the corresponding SNMP trap, enter the no version of the command, as
shown in the following example.
Syntax: [no] mac-movement notification interval-history <interval>
The <interval> variable represents the amount of time in seconds during which the MAC address
movement notification data is collected. It has no default value.
Viewing MAC address movement statistics
for the interval history
To display the collected history of MAC address movement notification, enter the show notification
mac-movement interval-history command at the privileged EXEC level. This command displays how
the history interval is configured in addition to the MAC address move data itself.
Brocade(config)# mac-movement notification interval-history 10
Brocade(config)# no mac-movement notification interval-history 10
Brocade# show notification mac-movement interval-history
