ZyXEL Communications IES4005M - Transparent VLAN Commands

Chapter 25 VLAN
IES4005M User’s Guide
185
This example shows the settings on VLAN 100. From the command output, The STPID is 88a8 and
packets sent by the IES are with C tag. Port 1 of the line card in slot 2 and Gigabit Ethernet ports 1
and 2 are the members.
This example adds Gigabit Ethernet port 2’s VLAN ID to 100 only. By default, the IES adds all
Gigabit Ethernet ports to all VLANs. You have to remove port 2 from all VLANs before adding it to
VLAN 100.
25.3 Transparent VLAN Commands
Transparent VLAN does not change the type of the VLAN tag in uplink and user (DSL) ports. You can
configure the S-tag TPID on the uplink port to be the same as the C-tag TPID on the DSL port
(0x8100) so the behavior appears truly transparent.
A port configured as transparent VLAN cannot join other VLAN modes.
See Section 25.1.1 on page 180 for more on transparent VLAN and command examples.
Note: Use the interface ge-nni <portlist> and vlan all commands to add Gigabit
Ethernet uplink ports to all VLANs (1 ~ 4093) to make sure VLAN transparent
traffic can go through the uplink.
