  1. Rene,
    Hi. In a normal working state, what does the interface status look like if one were to say issue a “show interface status” or “show interface F0/16” in this case?

    Many thanks.

  3. Hi Zaman,

    The backup link is not used at all…unless the primary link fails. One flexlink has 1 primary and 1 backup link, you can configure multiple flexlink pairs though…the maximum number depends on the platform.

  4. Hei Rene,

    Cisco says something else:

    If port 1 goes down, port 2 comes up and starts forwarding traffic to switch C. When port 1 comes back up, it goes into standby mode and does not forward traffic; port 2 continues forwarding traffic.

    But I Strongly agree with you! because i have done it on ME3400 live with customer:

    When it was nothing connected to Gig 0/2 on ME3400:
    GigabitEthernet0/1 GigabitEthernet0/2 <strong>Active Up/Backup Down</strong>

    When he connected the lan cabel to Gig 0/2:
    GigabitEthernet0/1 GigabitEthernet0/2 <strong>Active

    Thanks
