Syntax

Description

Specifies the connectivity association key (CAK) for a preshared key.

A preshared key includes a connectivity association key name (CKN) and a CAK. A preshared key is exchanged between two devices at each end of a point-to-point link to enable MACsec using dynamic security keys. The MACsec Key Agreement (MKA) protocol is enabled once the preshared keys are successfully exchanged. The preshared key—the CKN and CAK—must match on both ends of a link.

Default

No CAK exists, by default.

Options

hexadecimal-number

The key name, in hexadecimal format.

The key name is 32 hexadecimal characters in length. To maximize security, we recommend configuring all 32 digits of a CAK. If you enter a key name that is less then 32 characters long, the remaining characters are set to 0. However, you will receive a warning message when you commit the configuration.

Required Privilege Level

admin—To view this statement in the configuration.
