by the system. When the maximum number of packets is exceeded, the excessive protocol packets are
dropped.
Use the l2protocol-tunnel global drop-threshold command and the l2protocol-tunnel drop-threshold
command in the global configuration mode to leverage the bandwidth restriction.
Example
This example shows how to enable rate limiting globally.
Switch# configure terminal
Switch(config)# l2protocol-tunnel global drop-threshold 5000
Switch(config)#
56-6 l2protocol-tunnel shutdown-threshold
This command is used to specify a threshold in the tunneling of the specified Layer 2 protocol packets
received by a port before the shutdown. Use the no form of the command to reset to the default setting.
l2protocol-tunnel shutdown-threshold [gvrp | stp | protocol-mac {01-00-0c-cc-cc-cc | 01-00-0c-
cc-cc-cd}] PACKETS
no l2protocol-tunnel shutdown-threshold [gvrp | stp | protocol-mac {01-00-0c-cc-cc-cc | 01-00-
0c-cc-cc-cd}]
Parameters
gvrp
stp
01-00-0c-cc-cc-cc
01-00-0c-cc-cc-cd
PACKETS
Default
By default, this option is disabled.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
Use the command to restrict the CPU processing bandwidth consumption by specifying a threshold for
tunneling of the specified Layer 2 protocol packets received the port. When the threshold is exceeded, the
port is put in error-disabled state.
If protocol type is not specified, the setting applies to all protocol types.
The l2protocol-tunnel shutdown-threshold command can be used together with the l2protocol-tunnel
drop-threshold command. If drop threshold is also configured on the interface, the shutdown-threshold
value must be greater than or equal to the drop-threshold value.
Example
(Optional) Specifies GVRP tunneling.
(Optional) Specifies STP tunneling.
(Optional) Specifies the protocol packets with this destination DA.
(Optional) Specifies the protocol packets with this destination DA.
Specifies the threshold in number of packets per second This value
must be between 1 and 4096 packets.
