(Continued)

TABLE 2

Field

Description

MAC-Address

The MAC address that has moved to a different port.

from-Port

The port from which the MAC address moved.

to-Port

The port to which the MAC address moved.

Last Move-Time

The time of the last move occurred.It uses the system up time If there is no
time server configured.

Vlan-id

The VLAN for the port where the MAC address movement was detected.

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.

device(config)# mac-movement notification interval-history 10

To disable the feature and the corresponding SNMP trap, enter the no version of the command, as
shown in the following example.

device(config)# no mac-movement notification interval-history 10

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.

device# show notification mac-movement interval-history

Configured Interval : 30 seconds

Number of macs that moved in the interval : 100

Total number of moves in the interval : 98654
