    hello


    I need your help for spanning tree.
    These are 5130 switches with a firmware: 5130ei-cmw710-boot-r3208p08 where is set the spannin-tree to global and loopback detection on the interfaces
    global :

    <code>

    loopback-detection global enable vlan 1 to 4094
    loopback-detection interval-time 5

    shutdown-interval 0

    #
    stp region-configuration
    region-name test
    revision-level 1
    instance 1 vlan 1 to 199
    instance 2 vlan 200 to 399
    active region-configuration
    #
    stp instance 0 to 3 priority 8192
    stp bpdu-protection
    stp global enable

    Sur les interfaces:

    port link-type hybrid
    undo port hybrid vlan 2
    port hybrid vlan 3 untagged
    port hybrid pvid vlan 3
    broadcast-suppression pps 2001
    multicast-suppression pps 15001
    undo stp enable
    sflow flow collector 2
    sflow sampling-rate 1025
    sflow counter collector 2
    sflow counter interval 121
    qos trust dscp
    poe enable
    loopback-detection enable vlan 2 to 4094
    loopback-detection action shutdown

    </code>

    the problem is that when there is a loop on the switch or on a mini switch connect to the switch.
    There is a frame that goes back to the firewall for tan on the heart of networks hp5500 there is a parameterized stp:

    <code>

    stp region-configuration
    region-name test
    revision-level 2
    instance 2 vlan 1 to 199
    instance 3 vlan 200 to 399
    active region-configuration
    #
    stp instance 1 priority 0
    stp instance 2 priority 0
    stp instance 3 priority 0
    stp bpdu-protection
    stp enable

    </code>

    and on the interfaces of connections to the firewall there must have been: stp root-protection
    On hp5131 on hybrid interfaces there is loopback-detetion control enable.
    is that you have an idea to prevent the firewall receiving Tran.?
