Chapter 8 Configuring IEEE 802.1Q Tunneling and Layer 2 Protocol Tunneling

Configuring 802.1Q Tunneling on the Switch

These sections describe how to configure 802.1Q tunneling:

• Configuring 802.1Q Tunnel Ports, page 8-4

• Clearing 802.1Q Tunnel Ports, page 8-4

• Disabling Global Support for 802.1Q Tunneling, page 8-5

Note See Chapter 5, “Configuring Ethernet VLAN Trunks,” for information on using the global set

dot1q-all-tagged enable command.

Configuring 802.1Q Tunnel Ports

Caution When you configure tunneling in any VLAN, make sure that you configure only the appropriate tunnel

ports and that you use one VLAN for each tunnel. Incorrect assignment of tunnel ports to VLANs can

cause traffic forwarding problems.

To configure 802.1Q tunneling on a port, perform this task in privileged mode:

This example shows how to configure tunneling on port 4/1 and verify the configuration:

Console> (enable) set port dot1qtunnel 4/1 access

Dot1q tunnel feature set to access mode on port 4/1.

Port 4/1 trunk mode set to off.

Console> (enable) show port dot1qtunnel 4/1

Port Dot1q tunnel mode

----- -----------------

4/1 access

Clearing 802.1Q Tunnel Ports

To clear 802.1Q tunneling support from a port, perform this task in privileged mode:

Task Command

Step 1

Configure tunneling on a port. set port dot1qtunnel {all | mod/port access |

disable}

Step 2

Verify the configuration. show port dot1qtunnel [mod[/port]]

Task Command

Step 1

Clear tunneling from a port. set port dot1qtunnel {mod/port} disable

Step 2

Verify the configuration. show port dot1qtunnel [mod[/port]]
