Huawei quidway s7700 - Dividing a LAN into Vlans Based on Policies

l The optional parameter priority specifies the 802.1p priority value related to the
protocol. The value ranges from 0 to 7. The greater the value, the higher the priority.
The default value is 0. After the 802.1p priority value is specified, frames with high
priorities are first forwarded when traffic is congested.

3.3.6 Dividing a LAN into VLANs Based on Policies
VLANs configured based on policies are also called policy VLANs. Policy VLANs allow
terminals to plug and play and data for different users to be separately transmitted.
Context
A LAN can be divided into VLANs based on MAC and IP addresses or based on MAC and IP
addresses and interfaces.
To divide a LAN into VLANs based on policies, configure MAC and IP addresses of terminals
on a switch and associate pairs of MAC addresses ,IP addresses and interfaces with VLANs.
Only users matching a policy can be added to a specified VLAN. If the IP or MAC addresses
of users added to a VLAN are changed, they will exit from the VLAN.
Policy VLANs process only untagged frames. and treat tagged frames in the same manner as
VLANs configured based on ports.
After receiving an untagged frame, the device finds a VLAN matching both MAC and IP
addresses of the frame, and transmits the frame in the VLAN.
The configuration roadmap is as follows:
1. Create VLANs.
2. Associate pairs of MAC and IP addresses with VLANs to divide a LAN into VLANs based
on both MAC and IP addresses.
3. Configure the port type and features.
(1) Set the port type to hybrid.
(2) Configure a port to allow frames with specified MAC and IP addresses to pass through.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
vlan vlan-id
A VLAN is created, and the VLAN view is displayed. If the specified VLAN has been created,
the VLAN view is directly displayed.
The VLAN ID ranges from 1 to 4094. If VLANs need to be created in batches, run the vlan
batch { vlan-id1 [ to vlan-id2 ] } &<1-10> command to create VLANs in batches, and then run
the vlan vlan-id command to enter the view of a specified VLAN.
