    ISL is out-of-sync

    Solution 1

    Cause

    Mismatch with the ISL version or switch platform or both.

    Action

    1. Run theshow vsx statuscommand.

      2. In the following example, the ISL channel is shown as in-sync; however, if the ISL channel was not in-sync, a different status would be provided.

      switch#show vsx statusVSX Operational State --------------------- ISL channel : In-Sync ISL mgmt channel : operational Config Sync Status : in-sync NAE : peer_unreachable HTTPS Server : peer_unreachable Attribute Local Peer ------------ -------- -------- ISL link 1/1/43 1/1/43 ISL version 2 2 System MAC 48:0f:cf:af:70:84 48:0f:cf:af:c2:84 Platform 8320 8320 Software Version 10.0x.xxxx 10.0x.xxxx Device Role primary secondary

      switch(config)#user admin password改变密码用户管理员输入密码:* *********** Confirm password:************

    2. If there is an ISL version mismatch, update the software so the ISL version is the same on the local and peer VSX switch.
    3. If the switches have mismatching platforms, create an ISL link that connects two VSX switches with the same platform.

    Solution 2

    Cause

    The role is not configured on any of the VSX switches or the same role is configured on both VSX switches.

    Action

    1. Run theshow vsx statuscommand.

      If the roles are set incorrectly, the command displays therole inconsistentstatus.

    2. Set the roles correctly so that one of the VSX switches has the primary role and the other switch has the secondary role. To set a switch role, enter therole {primary | secondary}command.

    Solution 3

    Cause

    The ISL interface is down on any one switch in the VSX pair.

    Action

    1. Check ISL state and ISL link status by entering:switch#show vsx status inter-switch-link

      2. In the following example, the ISL state and link status are shown as in-sync and up; however, if the ISL interface is down, a different status would be provided.

      switch#show vsx status inter-switch-linkState : In-Sync Link Status : up Mgmt state : operational Inter-switch link Statistics ---------------------------- Hello Packets Tx : 4572 Hello Packets Rx : 4573 Data Packets Tx : 80634 Data Packets Rx : 80637 Mgmt Packets Tx : 25946 Mgmt Packets Rx : 25167 Mgmt Packet Drops : 0
    2. Re-enable the ISL interface by going to that interface context and enteringno shutdown:
      switch(config)#interface 1/1/1switch(config-if)#no shutdown
