Ip Subnet-Based Vlan Configuration; Introduction; Configuring An Ip Subnet-Based Vlan - H3C S5120-EI Series Operation Manual

Do not configure both the dsap-id and ssap-id arguments in the protocol-vlan command as 0xe0
or 0xff when configuring the user-defined template for llc encapsulation. Otherwise, the
encapsulation format of the matching packets will be the same as that of the ipx llc or ipx raw
packets respectively.
When you use the mode keyword to configure a user-defined protocol template, do not set etype-id
in ethernetii etype etype-id to 0x0800, 0x8137, 0x809b, or 0x86dd. Otherwise, the encapsulation
format of the matching packets will be the same as that of the IPv4, IPX, AppleTalk, and IPv6
packets respectively.
A protocol-based VLAN on a hybrid port can process only untagged inbound packets, whereas the
voice VLAN in automatic mode on a hybrid port can process only tagged voice traffic. Therefore, do
not configure a VLAN as both a protocol-based VLAN and a voice VLAN. For more information,
refer to Voice VLAN
After you configure a command on a Layer-2 aggregate interface, the system starts applying the
configuration to the aggregate interface and its aggregation member ports. If the system fails to do
that on the aggregate interface, it stops applying the configuration to the aggregation member ports.
If it fails to do that on an aggregation member port, it simply skips the port and moves to the next
port.

IP Subnet-Based VLAN Configuration

Introduction

In this approach, packets are assigned to VLANs based on their source IP addresses and subnet masks.
A port configured with IP subnet-based VLANs assigns a received untagged packet to a VLAN based on
the source address of the packet.
This feature is used to assign packets from the specified network segment or IP address to a specific
VLAN.

Configuring an IP Subnet-Based VLAN

This feature is only applicable on hybrid ports.
Follow these steps to configure an IP subnet-based VLAN:
To do...
Enter system view
Enter VLAN view
Configuration.
Use the command...
system-view
vlan vlan-id
1-13
