    Hi

     

    Am still a bit confused with the staging of both switches

     

    Config:

    There are 2 VLAN's per switch.  Two switches in total.  (sw1 & sw2)

    Default VLAN

    Data VLAN

    Software revision: W1470

     

    Servers are connected to the both switches in the data VLAN.  Two ports have been configured for trunks (2x1GB) between both switches.The trk2 resides in the data vlan.

     

    For testing purposes I plugged a server into sw2 data vlan but can not ping an ip in the data vlan in sw1.  This should work or not?

     

    Referance I looked at but is not clear to me.

    Thank you in advanced

    That should work. Could you paste some config?

    Should work if you tagged both trunk ports on the two switches data VLAN

    Thank you for your responce.

    Ports 17-20 are the candidates to link both 2910al switches

    Switch1 is current the primary switch and switch2 will be added to the config. Traffic must flow in an active/active state

    From switch2 ports 9-12 will be moved to switch2

     

    On switch1 it is TRK3 and switch2 its TRK2.  Tried the Trunk or LACP mode but still can not ping from switch2 to switch

    Be aware that the word "trunk" has a different meaning on ProCurve than most other switches. Here, trunk means link aggregation. What you need is not only to set up the trunk, but also configure the right VLANs on the trunk (which is the Cisco meaning of trunk).

    Are you really sure you want two separate 2 Gbps trunks? In most cases it would be better for them to share a single trunk, in a configuration like this:

    switch 1:

    vlan 1
    name default
    untagged ...,trk1
    ip address 1.2.1.1 255.255.255.0
    vlan 2
    name data
    tagged ...,trk1
    ip address 1.2.2.1 255.255.255.0
    trunk 17-20 trk1 lacp

    switch 2:

    vlan 1
    name default
    untagged ...,trk1
    ip address 1.2.1.2 255.255.255.0
    vlan 2
    name data
    tagged ...,trk1
    ip address 1.2.2.2 255.255.255.0
    trunk 17-20 trk1 lacp
