    Hi All,

    I want to know the exact difference between Ethernet Port Channel and Switchport mode trunk. For verification I am appending an example below

    interface Port-channel5
    description DOUNC0420-xtrem-a-port45-lacp-portchannel5-vlan490,2,3,-g9/5
    switchport
    switchport trunk encapsulation dot1q
    switchport trunk allowed vlan 420-422
    switchport mode trunk
    no ip address

    interface GigabitEthernet3/15
    description DORNC0418-RAN-TPEXT-RP-VLAN418-vlan428-CajunA
    switchport
    switchport trunk encapsulation dot1q
    switchport trunk allowed vlan 420-422
    switchport mode trunk
    no ip address
    udld port disable
    no cdp enable
    spanning-tree port-priority 112

    For these 2 interface configuration I don't see much difference. I don't know why they have created this port channel since it does not have multiple interface to tie together.

    I would appreciate if anybody can post an explanation about this.

    Thanks,

    Mansur
