### Description

```asn1
swL2IpMacBindingAllPortState OBJECT-TYPE
SYNTAX INTEGER {other(1), enable-strict(2), disable(3), enable-loose(4)}
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"This object enables/disables IP-MAC binding on all ports of the system.
This action is only applicable when users have write privileges,
and can only be viewed when users have read privileges.
Note:
enable-strict (2): This means strict mode (SW learning). All packets are sent
to the CPU. If the user chooses, the port will check ARP packets
and IP packets by IP-MAC-PORT Binding entries. If the MAC
address can be found or not found by the entry, the MAC will
be set as dynamic learned or it will set as blocked, respectively. Other
packets will be sent to the CPU and dropped.
enable-loose (4) : This means loose mode (HW learning): Only ARP packets and IP
broadcast packets will be sent to the CPU. If the user chooses ,
the port will learn the MAC address on non-ARP and non-IP
broadcast packets directly, so these packets will be bypassed.
But if the switch receives the ARP or IP broadcast packets and
Can not bypass the IP MAC Binding checking, the switch will set
this MAC address as blocked and all packets from this MAC
address will be dropped."
