Use the tca command to set the parameters for threshold crossing alerts.Use the no form of this command to return a special instance (that is, specific values for a named tunnel) to the default values.tca <tca-name> default {rising | falling} raise-threshold <value> clear-threshold <value> [sample-count <number of samples>]tca <tca-name> <tunnel-name> {rising | falling} raise-threshold <value> clear-threshold <value> [sample-count <number of samples>]tca <tca-name> {pass-through | pass-through-unshaped} {rising | falling} raise-threshold <value> clear-threshold <value> [sample-count <number of samples>]
tca <tca-name> Specifies which threshold crossing alert to configure. Some apply to one or more types of traffic. Others only have default values.
• file-system-utilization
How much of the file system space has been used, expressed as a percentage.

•
•
• oop-post-poc
Tunnel out-of-order packets, as tenths of a percent, after applying Packet Order Correction (POC).
• oop-pre-poc
Tunnel out-of-order packets, as tenths of a percent, before applying Packet Order Correction (POC).

•
• total-flows
Total number of flows.

• Sets the tca <tca-name> argument values for any tunnels that weren’t specifically named in configuring an argument. For example, if you configured latency values for tunnel_1 but not for tunnel_2 and tunnel_3, then configuring default would only apply values to tunnel_2 and tunnel_3. raise-threshold <value> clear-threshold <value>
• For a rising alarm, the clear-threshold value is equal to or less than the raise-threshold.
• For a falling alarm, the clear-threshold value is equal to or more than the raise-threshold Sets the number of samples that the metric must sustain below (or above) the threshold in order to raise (or clear) the alert.

n Use the no form of this command to return a special instance (that is, specific values for a named tunnel) back to the default values.
n To raise an alert when the percent reduction for tunnel_a falls below 60% and to clear the alarm as soon as reduction reaches 70%:
