This chapter describes the Cisco NX-OS TrustSec commands that begin with C.

clear cts policy

To clear the Cisco TrustSec security group access control list (SGACL) policies, use the clear cts policy command.

clear cts policy {all | peer device-id | sgt sgt-value}

Syntax Description

all	Clears all the Cisco TrustSec SGACL policies on the local device.
peer device-id	Clears the Cisco TrustSec SGACL policies for a peer device on the local device.
sgt sgt-value	Clears the Cisco TrustSec SGACL policies for a security group tag (SGT) on the local device.

Command Default

None

Command Modes

Any command mode

Command History

Release	Modification
5.1(3)N1(1)	This command was introduced.

Usage Guidelines

To use this command, you must first enable the 802.1X feature by using the feature dot1x command and then enable the Cisco TrustSec feature using the feature cts command.

When you clear the SGACL policies, the operation does not take effect until the interface is flapped. If the interface is a static SGT interface, the SGT value is set to zero (0) after the flapping. To undo this operation, use the following commands:

switch(config-if-cts-manual)# no policy static

switch(config-if-cts-manual)# policy static sgt sgt-value

switch(config-if-cts-manual)# 

If the interface is a dynamic SGT interface, the SGT is downloaded again from the RADIUS server after the flapping.

This command does not require a license.

Examples

This example shows how to clear all the Cisco TrustSec SGACL policies on the device:

switch# clear cts policy all

switch#
