Chapter 8 Configuring IEEE 802.1Q Tunneling and Layer 2 Protocol Tunneling
After reaching the shutdown threshold factor, the port or range of ports goes into the errdisable state and
Note
is restored after the errdisable timeout interval. The shutdown threshold factor should exceed the drop
threshold factor. After reaching the drop threshold factor, the port or range of ports starts dropping
PDUs.
The default for the drop threshold and the shutdown threshold is zero (0). A zero indicates that no limit
is set.
With software release 8.4(1) and later releases, you can specify the drop and shutdown thresholds for
Note
individual protocols on a per-port basis. If you configure thresholds only and do not specify a protocol,
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 cumulative basis and then per-protocol thresholds
are applied to the packets. The range for the per-port protocols drop threshold and shutdown threshold
is
from 0
To specify the drop and shutdown thresholds on a port, perform this task in privileged mode:
Task
Step 1 Specify the drop and shutdown thresholds on a
port.
Step 2 Verify the configuration.
This example shows how to specify a drop threshold of 500 and a shutdown threshold of 1000 on a port:
Console> (enable) set port l2protocol-tunnel 3/15 drop-threshold 500 shutdown-threshold
1000
Drop Threshold=500, Shutdown Threshold=1000 set on port 3/15.
Console> (enable)
This example shows how to specify a drop threshold of 100 and a shutdown threshold of 400 for the 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.
