Cannot establish MKA sessions between MACsec devices

The devices cannot establish MKA sessions when the following conditions exist:

• The link connecting the devices is up.

• The ports at the ends of the link are MACsec capable.

The symptom might occur for the following reasons:

• The ports at the link are not enabled with MKA.

• A port at the link is not configured with a preshared key or configured with a preshared key different from the peer.

To resolve the problem:

1. Enter interface view.

2. Use the display this command to check the MACsec configuration:

   • If MKA is not enabled on the port, execute the mka enable command.

   • If a preshared key is not configured or the preshared key is different from the peer, use the mka psk command to configure a preshared key. Make sure the preshared key is the same as the preshared key on the peer.

3. If the problem persists, contact Hewlett Packard Enterprise Support.
