Parameter  Description 
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.
