Adding VLANs to Teams
Each team supports up to 64 VLANs (63 tagged and 1 untagged). With multiple VLANs on an adapter, a server
with a single adapter can have a logical presence on multiple IP subnets. With multiple VLANs in a team, a
server can have a logical presence on multiple IP subnets and benefit from load balancing and failover. For
instructions on adding a VLAN to a team, see Adding a VLAN for Windows operating systems.
VLAN #3 Includes the Main Server, the Accounting Server and PC #4. This VLAN is an
accounting group.
Main Server A high-use server that needs to be accessed from all VLANs and IP subnets. The
Main Server has a Broadcom adapter installed. All three IP subnets are accessed
via the single physical adapter interface. The server is attached to one of the switch
ports, which is configured for VLANs #1, #2, and #3. Both the adapter and the
connected switch port have tagging turned on. Because of the tagging VLAN
capabilities of both devices, the server is able to communicate on all three IP
subnets in this network, but continues to maintain broadcast separation between all
of them.
Accounting Server Available to VLAN #3 only. The Accounting Server is isolated from all traffic on
VLANs #1 and #2. The switch port connected to the server has tagging turned off.
PCs #1 and #2 Attached to a shared media hub that is then connected to the switch. PCs #1 and
#2 belong to VLAN #2 only, and are logically in the same IP subnet as the Main
Server and PC #5. The switch port connected to this segment has tagging turned
off.
PC #3 A member of VLAN #1, PC #3 can communicate only with the Main Server and PC
#5. Tagging is not enabled on PC #3 switch port.
PC #4 A member of VLAN #3, PC #4 can only communicate with the servers. Tagging is
not enabled on PC #4 switch port.
PC #5 A member of both VLANs #1 and #2, PC #5 has an Broadcom adapter installed. It
is connected to switch port #10. Both the adapter and the switch port are configured
for VLANs #1 and #2 and have tagging enabled.
Note: VLAN tagging is only required to be enabled on switch ports that create trunk links to other
switches, or on ports connected to tag-capable end-stations, such as servers or workstations with
Broadcom adapters.
Note: Adapters that are members of a failover team can also be configured to support VLANs.
Because VLANs are not supported for a third-party NIC, if an third-party NIC is a member of a failover
team, VLANs cannot be configured for that team.
