Cannot ping network or gateway from VM even if VLAN is on 4095

hi.  i just setup a ESXi cluster.  i have 2 of the hosts on network A, and 1 of them on network B.  i've setup the 2 hosts on network A to all access network tag of 4095.  

shouldn't the 2 hosts on network A see network B fine?  i am told from the networking group the ports have been trunked to see all networks.

when i migrate a VM from network B to a host on network A, i cannot ping or access but the NIC is said to be configured.  is there anything i need to do on the vsphere still or is this still a networking configuration issue on switches?

    Accepted Solution

    Why are you using VLAN Tag 0f 4095, that is a special VLAN tag for VMware.

    If you network switches/ports that have been presented to your ESXi servers have been trunked.

    You need to specify the VLAN Tag, that corresponds to the VLAN Tag, configured on the trunk.

    So what VLANs have been configured on the trunk network and create Virtual Machine Network Portgroups with VLAN Tag, to send the traffic over.

    i think because it is allowed all for now.  i am not a networking person but i am seeing that network B has no VLAN tag to it, none (0).

    i think this is matter of trunking the ports correctly for network A/B.  thx hanccocka.
