Figure 5-613 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 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.
Action
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.
Tunneled 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.
Protocol MAC
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.
Protocol MAC
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.
