Shared VLAN uplinks

[dingding]

i created a virtual switch with 2 portgroups, say pg1 with VLAN id 100, pg2 with VLAN ID 2. since they share uplinks, how can i tag the unlinks with 2 VLAN ID?

i am not familiar with network.

or i must create 2 vswitches, each with 1 portgroup, and with different uplinks?

You now need your network administrators to configure the physical switches to allow 802.1q on the connected ports from these 2 uplinks.

Basically the physical switch is configured with a trunk port and then network team can decide which VLANs to allow through here.

Your ESX virtual switch will apply the tag to each packet and this will be read by the physical switch when it arrives.

Hope this helps.

so if i have only one virtual switch with 2 uplinks, and at network switch, configured this 2 uplinks as trunk, this trunk can transfer more than 1 VLAN traffic(say VLAN 101, VLAN 102), is that true?

Correct, you can have multiple VLANs in the valid range.
