I have XenServer installed on a HS21 blade server. The blade server has 2 NICs connected to an ESM which is connected to a Nortel 5520 switch via a trunk. I need to create an isolated VLAN to isolate a copy of the PROD network but do not have any spare NIC ports available. It appears that my best option is to use VLAN tagging and I am unsure how to configure this within the current setup. I cannot break the current trunk as this servers Production servers. The HS21 blade has 2 NICS that plug into 2 ESM ports, EXT0 and EXT1. This is then trunked in to 2 ports on the nortel switch, unit 1 port 1 and unit 1 port 2. I then have a virtual machine running on ESX which has an uplink assigned to a virtual switch which is plugged in to a separate port in the same switch as the trunk is plugged into, unit 1 port 4. I want to use VLAN ID 100. I have created a network VLAN in the XenServer with an ID of 100. I have also created a virtual switch in ESX and have specifed VLAN ID 100. I need to configure the trunk and the port the ESX uplink plugs in to, to be in the same VLANID of 100.
Can anyone point me in to the right direction?
