Manual VLAN pruning on a Cat 3550

    I realize that VLANS 1,1002-1005,1006-4094 are prune ineligible with
    VTP pruning, but I'm wondering about the correct procedure for manually
    pruning these VLANs from trunks. Since you can manually specify what
    VLANS are allowed on a trunk, and since you can allow only the VLANS
    that contain ports on both ends of the trunk, here's the
    question.....Should you manually prune and observe the prune ineligible
    VLANS in the 'switchport trunk allowed vlan' statement, or is it OK to
    only specify the VLANS that are common to the endpoint switches? I'm
    asking this primarily as to what might be expected on the CCIE Lab exam.
