    Participating Nodes Time not Synchronized

    Problem

    Description: If the time is not synchronized in the participating nodes, MKA session is not established and packet drops happen.

    Solution

    Use the following command to check whether MKA session is established:

    user@host> show security mka sessions

    If the session is not established, check whether the participating nodes are time synchronized:

    user@host> show ntp associations
    user@host> show ntp status

    If the servers are not time synchronized, execute the following command in the participating nodes.

    user@host> set date ntp ntp-server-name

    Sample Output

    user@host>show security mka sessions
