Usage guidelines
This feature enables the device to detect and record user port migrations. A user port migrates if an
incoming NA packet has the same source IPv6 address and source MAC address as an existing
ND entry but a different port. The device generates a user port migration record, logs the migration
event, and sends the log to the information center. For information about the log destination and
output rule configuration in the information center, see the information center in
Network
Management and Monitoring Configuration Guide .
Each IRF member device can generate a maximum of 10 user port migration logs per second.
When this maximum number is reached, the member device suppresses generating user port
migration logs and records the suppression times. Each IRF member device can save a maximum
of 200 user port migration records.
When the number of saved user port migration records reaches the upper limit, new records
overwrite old ones.
