You cannot delete a protocol-based VLAN on a port while the port is associated

with the VLAN.
The following sections describe the IP subnet-based VLAN configuration tasks:
Associating/dissociating a specified port with/from an IP subnet-based VLAN

Configuring an IP subnet-based VLAN
■
Use the following commands to associate/dissociate a specified port with/from an
IP subnet-based VLAN.
Perform the following configuration in Ethernet port view.
Table 41 Associate/dissociate a port with/from an IP subnet-based VLAN

The CPU is a special port in the Switch 8800 Family series routing switches. By
default, because the CPU port is in a VLAN, when common broadcast packets and
unknown multicast packets are broadcast within a VLAN, these packets will also
be broadcast to the CPU. To prevent waste of CPU resources, you can move the
CPU port out of the VLAN, so that common broadcast packets and unknown
multicast packets will not be handed to the CPU for processing.
You can use the following command to move the CPU port out of the VLAN.
Perform the following configuration in VLAN view.
Table 43 Move the CPU port out of/into the VLAN
Operation
Move the CPU port out of the VLAN
Move the CPU port into the VLAN
By default, the CPU port is in the VLAN.
