Server VLAN Tag Settings
VLAN tunneling support
You can tunnel VLAN tags and map VLAN tags in the same domain. As of VC 3.30, tunneling and mapping
is configured at the network level, not at the domain level. Server VLAN tunneling is supported only on
networks with dedicated uplinks and cannot be used with shared uplink sets.
Server VLAN tagging support
When the 'Force server connections to use same VLAN mappings as shared uplink sets' check box is
selected, server ports connected to multiple VC Ethernet networks are forced to use the same VLAN mappings
as those used for the corresponding shared uplink sets. This action forces all server connections mapped to
multiple networks to be linked to a shared uplink set. Server administrators cannot override this selection
when creating or editing a profile. When this check box is selected, server network connections can only be
selected from a single shared uplink set.
When the 'Force server connections to use same VLAN mappings as shared uplink sets' check box is not
selected, server network connections can be selected from any VC Ethernet network and the external VLAN
ID mappings can be manually edited. However, administrators must ensure that no server connection VLAN
ID conflict exists.
The 'Force server connections to use the same VLAN mappings as shared uplink sets' check box can be
selected if no server profile connections are assigned to multiple networks that are not linked to a shared
uplink set.
VLAN capacity
Virtual Connect imposes certain limits on the number of networks (VLANs) in the domain and the server
connections carrying multiple VLANs. In a VC domain that does not contain legacy (1/10Gb) VC Ethernet
modules, these restrictions can be relaxed to provide support for more VLANs and enhance the flexibility of
