43-30 enable address_binding roaming
Description
This command is used to enable IMPB roaming. When a client was authenticated on the specified
port, using the DHCP/ND snooping function, the Switch will allow this authenticated client (VLAN
ID and MAC address) to change to another port if it detects a new DHCP/ND process caused by
the Station Move function. This behavior is known as roaming.
When IMPB roaming is enabled, the dynamic authenticated MAC address which learned through
DHCP/ND snooping on specific port can change to another port if it detects (1) a new DHCP
process belong to same IP and MAC address or (2) a new DAD process belong to same IP and
MAC.
Format
