ISL Trunking X6-8 and M6505

  • 1.  ISL Trunking X6-8 and M6505

    Posted 12-12-2019 10:46 AM
    Hello I have added some additional connections between an edge switch M6505 and our san directors a pair of X6-8s. When I added more ISLs I made sure to cable the new connection within the same ASIC I believe. I expected to see a 2X32GB trunks instead of the 4x16GB trunk masters that I am seeing now. I don't know if I need to move one of the sets of cables, or disable one of the ports to get the connection I need. Thanks

    9/29
    10/29

    new ISLs on X6-8s
    9/35
    10/35

    Hello,

    you don't met requirements for forming of trunk.

    From admin guide:

    One of the conditions is that all of the ports in a trunk group must belong to
    the same port group. A port group is a group of eight ports, based on the user port number, such as 0-7, 8-15, 16-23, and up to the
    number of ports on the switch.

    You can see portgroups with command:
    /
    porttrunkarena --show all

    In your particular case in switch blade No. 9:

    205 9 29 65cd00 id N16 Online FC E-Port 10:00:88:94:71:39:2b:75 "sw102" (downstream)(Trunk master)
    323 9 35 65cb80 id N16 Online FC E-Port 10:00:88:94:71:39:2b:75 "sw102" (Trunk master)

    You choose port which they are not on same portgroup. So you have to recable for example 9/35 in ports 9/24 - 9/31


    Same issue there with second connection on slot 10.

    Be aware that ports must met this requirement on both switches which would like to form Trunked ISL.
    It's not necessary to use same ports. Its' enough to use ports from same port group.
