Migration from 8212zl to 5412r: Inter-VLAN routing

  • 1.  Migration from 8212zl to 5412r: Inter-VLAN routing

    Posted Jul 27, 2020 02:55 PM

    Hello all;

     

    This weekend I swapped out my MDF old 8212zl switch for a newer 5412r. Most of it went smoothly, but I am having major problems between VLANs. I cannot consistenly reach or ping one side of the network to another on VLAN-10. I have not changed the configuration on any of my IDF switches, and copied the config from the 8212zl onto the 5412r.

    From MDF 5412r to client:

    mdf-hp5412r# ping 10.17.10.243
    10.17.10.243 is alive, time = 1 ms
    mdf-hp5412r# ping 10.17.10.243
    Request timed out.
    mdf-hp5412r# ping 10.17.10.243
    10.17.10.243 is alive, time = 1 ms
    mdf-hp5412r# ping 10.17.10.243
    10.17.10.243 is alive, time = 1 ms
    mdf-hp5412r# ping 10.17.10.243
    Request timed out.

     

    Client to client:

    Request timed out.
    Request timed out.
    Request timed out.

    IDF Switch to client (switch that client is directly connected to):

    Request timed out.
    do-hp-e3500yl-0# ping 10.17.0.243

  • 2.  RE: Migration from 8212zl to 5412r: Inter-VLAN routing

    Posted Aug 17, 2020 01:11 PM

    Hi,

     

    just to start some troubleshooting I have a few questions:

     

    First I see that you ping 10.17.10.243 from MDF and client but from IDF you ping 10.17.0.243. Is it a typo maybe?

     

    Did you configure an IP address on the user VLAN on IDF while pinging then client from there? Because if you don't do this the ping will be send to MDF first an then routed from there to user VLAN.

     

    Did you double check the trunks? What are all the trunks on MDF used for? I guess three are for IDF (one each). And the last one?

    It would help if you show the trunking in your picture more detailed.
