15.1.39 vlan internal
Command: vlan <2-4094> internal
Function: Specify the internal VLAN ID. After an ID is specified as the internal VLAN ID,
it is not allowed to be used by other VLAN. Internal VLAN is only used to LOOPBACK

Usage Guide: Set 1006 as the default internal VLAN ID, the internal VLAN ID needs to
be modified when the network set 1006 as VLAN ID. Internal VLAN ID must select an
unused ID or else affect other VLAN. This command takes effect after save the
configuration and reboot the switch.
Example: Set 100 as the internal VLAN ID.
Switch(config)#vlan 100 internal
15.1.40 vlan ingress enable
Command: vlan ingress enable
no vlan ingress enable
Function: Enable the VLAN ingress filtering for a port; the “no vlan ingress enable”
command disables the ingress filtering.
Command mode: Global Mode
Default: Enable VLAN ingress filtering function.
Usage Guide: After VLAN ingress filtering is enabled on the port, when the system
receives data it will check source port first, and forwards the data to the destination port if
it is the VLAN member port, or else drop the data.
Example: Disable VLAN ingress rules on the port.
Switch(config)#no vlan ingress enable
