  • 1.  Spanning Tree on MDF/IDF's

    Posted Jun 02, 2017 01:05 PM

    Hi,

    I have seen/read mutiple posts on spanning-tree but still wanted some clarification.

    My core is Cisco routers - 6807's and I have multiple MDF and IDF's. We are starting to implement more and more HP 5400 zl chassis. So there is mixed HP and Cisco environment.

    My root switch is and/or should be the Cisco Router. This is what I have been told.

    My questions :

    1.  If the root switch is Cisco 6807 - I will have to have all VLAN's with a pripority of 0. Is that correct?

    2. What about all the MDF's - do I set - spanning-tree priority 2 force-version rstp-operation" or spanning-tree force-version rstp-operation (default of 8)

    3. What about the IDF's ? do I leave them at - spanning-tree force-version rstp-operation (default of 8)

    The reason I am asking is because - sometimes we are getting "errdisable" on the LACP links on the Core 6807.

    Thanks,

    P
