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. For AES-128 the CAK key length is 32 hexadecimal characters, and for AES-256 it is 64. If you enter a key name with fewer characters than the standard (32 for cipher-suite gcm-aes-128, and 64 for cipher-suite gcm-aes-256), Junos will automatically fill in the remaining characters with zeros. |
