Sample Configuration 2: VC Uplinks Connected to Cisco VLAN Trunk Ports
The figure below shows a VC and Cisco VLAN Trunking scenario and the minimum configuration
required on the Cisco switch. The uplinks on VC-Enet module VC1 are assigned to a vNet named
“vNet_VLANTunnel1” that is functioning as a 802.1Q tunnel for external VLAN IDs 2 thru 4 to server 1
and 2 (both ESX servers using VLAN tagging on NIC 1). The uplinks on VC-Enet module VC2 are
assigned to a Shared Uplink Set and are VLAN Trunk ports. The Shared Uplink Set is configured with
VLAN IDs 2 thru 4 corresponding to vNets “vNet_VLAN2_B”, “vNet_VLAN3”, and “vNet_VLAN4”
respectively. Server 2 NIC 2 and all NICs on Servers 3 and 16 are untagged and assigned to single
VLANs from the Shared Uplink Set. In addition, the Shared Uplink Set and vNet_VLANTunnel1 both
have their connection mode set to “failover”.
