\
    --no-enabled 

Replace INTERCONNECT_CONNECTION_NAME with the name of your Cloud Interconnect connection.

Console

1. In the Google Cloud console, go to the Cloud Interconnect Physical connectionstab.

   Go to Physical connections

2. Select the connection that you want to view.

3. The Link circuit infosection displays the following information:

   • Google circuit ID:the name of the link circuit.

   • Link state:the LACP member link's physical state displays a check_circle Checkand Activeto indicate that the LACP member link is up.

   • MACsec key name:the field is empty when MACsec is disabled.

   • Receiving optical power:a check_circle checkindicates an acceptable connection. The optical light level that the physical interface detects from the remote transmitter is displayed in dBm .

   • Transmitting optical power:a check_circle checkindicates an acceptable connection and the optical light level that the physical interface is transmitting to the remote receiver is displayed in dBm.

4. MACsec configurationdisplays Disabledto indicate that MACsec encryption is disabled on the link.

gcloud

To verify your Cloud Interconnect MACsec configuration, run the following command:

 gcloud compute interconnects describe INTERCONNECT_CONNECTION_NAME 
 

The output is similar to the following:

The following items specify the MACsec connections's configuration:

• macsec.failOpen :the connection's behavior if Cloud Interconnect can't establish an MKA session with your router. The value is either of the following:

  • false :if an MKA session can't be established, then Cloud Interconnect drops all traffic.

  • true :if an MKA session can't be established, then Cloud Interconnect passes unencrypted traffic.

• macsec.preSharedKeys.name :the list of all pre-shared keys configured for Cloud Interconnect on this link.

• macsec.preSharedKeys.startTime :when the current pre-shared key became valid. All keys have infinite validity.

• macsecEnabled :MACsec status for Cloud Interconnect on this link. The value is either of the following:

  • false :MACsec for Cloud Interconnect is off.

  • true :MACsec for Cloud Interconnect is on.

This command doesn't display MACsec operational status.
