Virtual Edition on ESXi Multiple VLANS on Interface

For the "internal" vlan I have the ESX network adapter (type VMXNET 3) associated with several vlans (port group listing specific vlans), also using a distributed switch. I have self IPs associated with each vlan address range. The issue is that some vlans work and others do not. Ping or ICMP node monitor does not work for a node in vlanA address range even though the vlan is defined with associated self IPs. A couple of the vlans associated with the adapter work. The route table looks good but there are incomplete entries in the ARP table for the troubled vlan.

    Mmm... I'd check the VLAN config on the VMWare side... Are you running the VMWare basic switch or something like the Nexus v1000?

    VLAN Group? Why do you want to use a VLAN group? Do you need the BigIP to bridge VLANs?

    Well... That looks like no continuity between the two VM's for that VLAN (i.e. Nothing obvious wrong with the dump). You might need to talk to a VMWare guy to see what they can verify on the virtual switch itself.

     

    Had a thought... Do you still see the outgoing traffic if you tcpdump on the interface itself, rather than 0.0 (i.e. 1.1 or whatever you're using).

    Cool. I just wanted to make sure... It certainly sounds like a problem in ESX. Not in your BigIP config.
