    Hi there

    I have HP Aruba 3810 on one end and HP Aruba 8360 on the other end . I created a lag interface on 8360 sw for the trunk port to hp 3810. Here's the configuration

    HP Aruba 8360:

    interface lag 19

        no shutdown

        no routing

        vlan trunk native 50

        vlan trunk allowed all

        lacp mode active


    HP Aruba 3810:

      trunk 15 trk15 trunk

    But it doesn't ping. How can we create a trunk port at hp aruba 3810 switch to connect with core switch hp aruba 8360.?


    Regards


    Khan

    Lag 19 needs a member port like your trunk 15. You will need to add configuration to the physical port you are using on the 8360 and add the "lag 19" command.

    Also, on the 3810 side, make sure you are untagging VLAN 50 on trunk 15 to match the native VLAN on the 8360 side.

    I assigned interface 19 to lag 19 on core switch.

    HP Aruba 3860

    CoreSW# show run int lag 19
    interface lag 19
    no shutdown
    no routing
    vlan trunk native 50
    vlan trunk allowed all
    lacp mode active
    exit


    CoreSW# show run int 1/1/19
    interface 1/1/19
    no shutdown
    description Link To AOA
    lag 19
    exit
    ---------------------------------------
    HP Aruba 3810
    vlan 1
    name "DEFAULT_VLAN"
    no untagged 15
    untagged 12-14,Trk1-Trk11,Trk16,Trk15
    ip address 172.22.x.x 255.255.255.0
    ipv6 enable
    ipv6 address dhcp full
    exit

    trunk 15 trk15 trunk

    vlan 50
    name "Management"
    untagged 15
    ip address 172.30.x.x 255.255.255.0
    exit

    Can you check the 3810 trunk configuration. I am sure there's something wrong on sw 3810 trunk port configuration.

    Is the usage of LAG (Link Aggregation Group) on Aruba 8360 and Port Trunking (Links Aggregation) on Aruba 3810 intentional? I mean...you're using just on physical port per side...that's a simple link (no necessity to setup a LAG/Port Trunking).

    In any case the Port Trunking on Aruba 3810 shouldn't be of type "trunk" but it should be instead of type "lacp" (to match the LAG type on Aruba 8360 side).

    Yes, LAG 19 on Aruba 8360 and try to port trunk on Aruba 3810. 

    Let me explain. On HP Aruba 8360 core switch  port number 19 . I assigned to LAG 19. 
    On HP Aruba 3810 Port 15 I want to link with hp aruba 8360 on port 19. 

    So should I create port 15 on hp aruba 3810 like this as follow.

     trunk 15 trk15  lacp

    I am new to hp and don't know how to establish this link between core switch 8360 and 3810 sw.

    Parnassus was asking if you were truly creating a port-channel (Trunk on 3810, and Lag on 8360). These take two interfaces on the same device and make a bonded logical interface.

    If you are looking to just create a trunk as in a port that carries multiple vlans, then there is no need for the trunk or lag commands.  For instance lets say your default or untagged vlan is 50. You also want to carry traffic for vlan 10, 11, and 12 on the same link. You would do the following:

    On the 3810:
    config t
    vlan 50 untagged 15
    vlan 10-12 tagged 15

    On the 8360:
    config t
    interface 1/1/19
    no routing
    vlan trunk native 50
    vlan trunk allowed 10-12,50
