Do not change the default value.
= 1, the switch will discard packets whose VID
port membership in VLAN table bits [18:16] does
not include the ingress port.
= 0, no ingress VLAN filtering.
= 1, the switch will discard packets whose VID
does not match ingress port default VID.
= 0, no packets will be discarded
= 1, will always enable full duplex flow control on
the port, regardless of AN result.
= 0, full duplex flow control is enabled based on
AN result.
= 1, enable port’s half duplex back pressure
= 0, disable port’s half duplex back pressure
= 1, enable packet transmission on the port
= 0, disable packet transmission on the port
= 1, enable packet reception on the port
= 0, disable packet reception on the port
= 1, disable switch address learning capability
= 0, enable switch address learning
