L2 Protocol Tunnel This window is used to display and configure the Layer 2 protocol tunnel settings. To view the following window, click L2 Features > L2 Protocol Tunnel, as shown below: Figure 5-62 L2 Protocol Tunnel (L2 Protocol Tunnel Global Setting) Window The fields that can be configured are described below: Parameter Description CoS for Encapsulated Packets Select the CoS value for encapsulated packets here. This value is between 0 and 7. Select the Default option to use the default value. Drop Threshold Action Tunneled Protocol Protocol MAC MAC Address Enter the drop threshold value here. This value must be between 100 and 20000. By default, this value is 0. The tunneling of the Layer 2 protocol packets will consume CPU processing power in encapsulating, decapsulating, and forwarding of the packet. Use this option to restrict the CPU processing bandwidth consumed by specifying a threshold on the number of all Layer 2 protocol packets that can be processed by the system. When the maximum number of packets is exceeded, the excessive protocol packets are dropped. Select the Default option to use the default value. Select the action that will be taken here. Options to choose from are Add and Delete. This is used to add or delete an L2PT tunneling multicast address to or from the specified protocol. Select the tunneled protocol here. Options to choose from are: • GVRP - Specifies that GVRP packets will be tunneled to the configured address. • STP - Specifies that STP packets will be tunneled to the configured address. • MAC - Specifies that protocol packets with the specified destination address will be tunneled to the configured address. • All - Specifies that all packets will be tunneled to the configured address. After selecting the MAC option as the Tunneled Protocol, select the destination address that will be tunneled to the configured address here. Options to choose from are 01-00-0C-CC-CC-CC and 01-00-0C-CC-CC-CD. Enter the MAC address which the specified protocol will be tunneled to here. This MAC address should not be an address reserved or used by other protocols. Click the Apply button to accept the changes made. 164
