Note The shutdown threshold factor should exceed the drop threshold factor. After reaching th e drop threshold
factor, the port or range of ports starts dropping PDUs. After reaching the shut down threshold factor, the
port or range of ports goes into errdisable state and is restored after timeout.
Note With software release 8.4(1) and later releases, you can specify the drop and shutdown thresholds for
individual protocols on a per-port basis. If you configure thresholds only and do not specify a proto col,
the packets are rate limited cumulatively irrespective of protocols. If you specify a threshold for a
protocol on a port, the packets are rate limited on a cum ula tive basis, and t hen p er-pro toco l th resh olds
are applied to the packets. The range for the per-port protocols drop threshold and shutdown threshold
is from 0 to 65535.
Examples This example shows how to enable CDP on a range of ports:
Console> (enable) set port l2protocol-tunnel 7/1-2 cdp enable
Layer 2 protocol tunneling enabled for CDP on ports 7/1-2.
Console> (enable)
This example shows how to enable STP and VTP on a range of ports:
Console> (enable) set port l2protocol-tunnel 7/1-2 stp vtp enable
Layer 2 protocol tunneling enabled for STP VTP on ports 7/1-2.
Console> (enable)
This example shows how to disable CDP, STP, and VTP on a range of ports:
Console> (enable) set port l2protocol-tunnel 7/1-2 cdp stp vtp disable
Layer 2 protocol tunneling disabled for CDP STP VTP on ports 7/1-2.
Console> (enable)
This example shows how to set the drop threshold to 1000 and the shutdown threshold to 20000 on a port:
Console> (enable) set port l2protocol-tunnel 7/1 drop-threshold 1000 shutdown-threshold
20000
Drop Threshold=1000, Shutdown Threshold=20000 set on port 7/1.
Console> (enable)
This example shows how to specify a drop threshold of 100 and a shutdown threshold of 400 fo r CDP
packets on a port:
Console> (enable) set port l2protocol-tunnel 3/1 drop-threshold 200 shutdown-threshold 400
cdp
Drop Threshold=200, Shutdown Threshold=400 set on port 3/1.
Console> (enable)
