DXS-3600 Series Layer 3 Managed 10Gigabit Ethernet Switch CLI Reference Guide
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
The tunneling of the Layer 2 protocol packets will consume CPU processing power when encapsulating,
decapsulating and forwarding packets. Use this command to restrict the CPU processing bandwidth
consumption by specifying a threshold in the tunneling of the specified Layer 2 protocol packets received
by a port before it is dropped. When the threshold is exceeded, the excessive incoming packets are
dropped.
If protocol type is not specified, the setting applies to all protocol types.
The l2protocol-tunnel drop-threshold command can be used together with the l2protocol-tunnel
shutdown-threshold command to restrict the processing bandwidth. If the shutdown threshold is also
configured on the interface, the drop-threshold value must be less than or equal to the shutdown-
threshold value.
Example
This example shows how to configure the drop threshold for the STP protocol.
Switch# configure terminal
Switch(config)# l2protocol-tunnel drop-threshold stp 2000
Switch(config-if)#
56-5 l2protocol-tunnel global drop-threshold
This command is used to specify the maximum number of Layer 2 protocol packets that can be
processed by the system per second. Use the no form of the command to reset to the default setting.
l2protocol-tunnel global drop-threshold PPS
no l2protocol-tunnel global drop-threshold
Parameters
PPS
Default
By default, this option is disabled.
Command Mode
Global Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
The tunneling of the Layer 2 protocol packets will consume CPU processing power in encapsulating,
decapsulating, and forwarding of the packet. Use the command to restrict the CPU processing bandwidth
consumed by specifying a threshold on the number of all Layer 2 protocol packets that can be processed
Specifies the maximum rate of incoming Layer 2 protocol packets that
can be tunneled. This value must be between 100 and 20000.
