Parameters
interval interval-value: Sets a detection interval for MAC address moves, in the range of 1 to 60
minutes. If you do not specify this option, the default setting of 1 minute is used.
Usage guidelines
With MAC address move notifications enabled, the system displays the MAC address move logs
when it detects MAC address moves. Each record of the MAC address move logs contains the
following information:
•
MAC address.
•
VLAN ID of the MAC address entry.
•
Current port and source port of the MAC address moves.
•
Number of MAC address moves within a MAC move detection interval.
After you execute this command, the system sends only syslog messages to the information center
module. If the snmp-agent trap enable mac-address command is also executed, the system also
sends SNMP information to the SNMP module of the device.
Within a detection interval, an IRF member device can display a maximum of 20 MAC address move
records. The latest record will override the oldest one.
Within a detection interval, an IRF member device can display a maximum of 20 MAC address move
records, and the subsequent records will be discarded. The latest record will override the oldest one
generated in the preceding detection interval.
