The official names of these configurations are an 802.1q Tunnel and an EtherChannel over an 802.1 q Tunnel.Lets start with the basic 802.1q Tunnel (aka The Tube or more commonly QinQ tunneling). The first item of note is that in order for this to work, you will need to change the system mtu to 1504 By using 802.1Q tunneling the layer 2 domain of a customer can be extended across multiple sites. A Q-in-Q frame can be identified by the Ethertype fieldIn order to support frames larger than 1500 bytes on Ethernet ports we can use the command system mtu in global configuration mode. When configuring Q-in-Q tunneling the ports connected directly to the customer switch are configured with the command switchport trunk encapsulation dot1q. The customer ports are configured as per normal and require no extra configuration. The Juniper Networks Junos operating system implementation of Q-in-Q tunneling supports the IEEE 802.1ad standard. Note: This task uses a Junos OS release that supports the Enhanced Layer 2 Software (ELS) configuration style. Any tunnel port in a tunnel VLAN is a tunnel entry and exit point.
An 802.1 Q tunnel can have as many tunnel ports as are needed to connect customer switches.Chapter 17 Configuring IEEE 802.1Q Tunneling. 802.1Q Tunneling Configuration Guidelines and Restrictions. The following configuration on the C-VLAN interface ge-0/0/1 enables Q-in -Q tunneling and maps packets from C-VLANs 100 through 200 to logical interface 10, which is in turn associated with S-VLAN v10. Layer 2 Switching Configuration. Q-in-Q Basic Port Configuration. Q-in- Q tunneling allows service providers on Ethernet access networks to extend a Layer 2 Ethernet connection between two customer sites. SCENARIO PURPOSE .

Cisco Systems 3750-X инструкция : Configuring IEEE 802.1Q and Layer 2 Protocol Tunneling 12.2.2 802.1Q Tunneling Configuration Guide. In configuring the 802.1Q, it is required to confirm that the connection with the 802.1 Q tunnel is an asymmetric link, with a VLAN dedicated for each tunnel. Q-in-Q Configuration To display Q-in-Q tunnel and Layer 2 protocol tunneling configuration information, perform one of the following tasks: Command clear l2protocol tunnel counters [interface if-range] Purpose Clears all the statistics counters. switchport mode dot1q-tunnel. This configuration will transport and preserve all the vlan information of the customer. Here in example, As fa0/13 is a trunk port, CP1 will transmit all the tagged frames on it. 802.1Q tunneling expands VLAN space by using a VLAN-in-VLAN hierarchy and tagging the tagged packets, and the maximal VLAN number can reach 4096 This example shows how to configure a switchport to basic dot1q-tunnel port. You can use show the configuration on the switchport. However, this is very limiting, both in that it removes the customers flexibility to choose their own VLAN numbers, and there may not be enough VLAN numbers (we can only use a maximum of 4,094 or so) available on large networks.802.1Q Tunnel Configuration. VLANs configured for a VLAN-transparent service and a VLAN-specific service follow the VLAN-specific service configuration. If you need to configure 802.1Q tunneling, configure this VLAN-transparent service in the normal manner, see the " Configuring IEEE 802.1Q Tunneling" section. 802.1Q Tunnel Configuration.Howie (guest) January 21, 2015 at 2:20 p.m. UTC.
