Usage Guidelines
You must enable flow control on the interface by using the flowcontrol {send | receive} command.
When you enter the no encrypt pause-frame command, the pause frames are sent as unencypted. When you
enter the encrypt pause-frame command, pause frames are sent encrypted over the Cisco TrustSec link.
You cannot enable Cisco TrustSec on interfaces in half-duplex mode. Use the show interface command to
determine if an interface is configured for half-duplex mode.
F1 Series modules, F2 Series modules, F2e Series modules, and the N7K-M132XP-12(L) module support
only clear pause frames. All other M1 Series modules support both secure (encrypted and decrypted) and
clear pause frames.
Note
For the pause frame encryption or decryption configuration to take effect, you must enable and disable
the interface, which disrupts traffic on the interface.
Caution
This command does not require a license.
Examples
This example shows how to decrypt an interface:
switch# configure terminal
switch(config)# interface ethernet 2/2
switch(config-if)# cts dot1x
