  • 1.  Struggling with an odd issue with three aruba switches, 1-6200 and 2- cx 8320's

    Posted Feb 22, 2024 04:16 PM

    So i've got a "core" switch that is the 1gb with 4 sfp port 6200 and two 10gb cx8320 switches.  Both 8320s have 10gb trunk ports to the 10gb ports on the 6200.   Here's where things get weird.  One of the cx8320's is communicating just fine, no issues at all.  The other 8320 (which houses vmware VMs on default vlan 1), I can ping from my laptop plugged into to the 6200 without issue, however that's the only communication I can achieve with the devices on that 8320.   The other is receiving data through the firewall without issue.  I've set ip routes on both the problematic 8320 and 6200 "core", including making that the ip address of vlan 1 without any success.  Here's my core config, I'm about at the end of my rope with this one, someone please help!

    Hi, given the description of your switches interconnections (two 10G links from two Aruba 8320 switches - one link for each 8320 - to one 6200) and given this part of 6200's uplink interfaces configuration:

    interface 1/1/49
        description Core to 10gb Internal <----- Aruba 8320
        no shutdown
        no routing
        vlan trunk native 1
        vlan trunk allowed 1,20
    interface 1/1/50
        shutdown
        no routing
        vlan trunk native 1
        vlan trunk allowed all
    interface 1/1/51
        description Core to ISCSI/DMZ <----- ?
        no shutdown
        no routing
        vlan trunk native 1
        vlan trunk allowed 30,110-122,140-142
    interface 1/1/52
        no shutdown
        no routing
        vlan trunk native 1
        vlan trunk allowed all

    where is the second 10G link to 8320?

    Were the two Aruba 8320 deployed as a VSX (thus clustered) or are they working independently each other (two standalone switches)?

    Hello,

    Yes it's port 51 and they were deployed as two stand alone switches and the 8320 connected to port 51 is the one that is working properly.

    Thanks!

    Ports 1/1/49 and 1/1/51 show different (allowed) VLANs membership and identical (native) VLAN membership: is this correct considering your current network design (I mean: compliant with the way your VLANs are needed and transported across your switches)?

    Who is doing the IP Routing duties to permit inter-VLAN traffic (you cited a Firewall...)?

    Yes, they are separate networks on those vlans, the 8320 switch that's working (attached to port 51 contains our DMZ and ISCSI networks) whereas the 8320 that isn't working properly (attached to port 49) contains our internal network and vmotion network only.  Ports 1 and 2 on the 6200 are connections to our two palo alto 440's, which are the virtual routers for all networks.

     

    Thanks!

    If, as you told, the VLAN Ids memberships are correct on each ports (you know), then the issue could be at higher level...personally I use another approach while assessing a problem but each network is the results of its design...so it's up to you to check each involved piece.
