  • VLAN to VLAN trunking

    Hi ,

    I have two 6509 Cisco Switches both are in HSRP with identical config.

    Currently all the vlans created are communicating with a single trunk port between the two switches.

    Now new requirement is that I need to have two of the vlans to have its own trunk port..

    e.g Vlan - 1 to Vlan -5 has trunkport Gb eth 1/48
    Vlan -21 trunkport Gb eth 2/2
    Vlan-31 trunkport Gb eth 2/3

    What commands should i need to use for this.

    Current Spanning tree setiing is PVST.

    Will this affect the new setup with any loop?

    Pls advise.

    Thanks and regards

    Why trunk a port that's only carrying one vlan?

    In any case you would trunk the port as normal and do something like this:


    >e.g Vlan - 1 to Vlan -5 has trunkport Gb eth 1/48
    switchport trunk allowed vlan 1-5

    >Vlan -21 trunkport Gb eth 2/2
    switchport trunk allowed vlan 21

    >Vlan-31 trunkport Gb eth 2/3
    switchport trunk allowed vlan 31
