Types of VLANs

ExtremeWare XOS 10.1 Concepts Guide 63

Spanning Switches with Port-Based VLANs

To create a port-based VLAN that spans two switches, you must do two things:

1 Assign the port on each switch to the VLAN.

2 Cable the two switches together using one port on each switch per VLAN.

Figure 2 illustrates a single VLAN that spans a BlackDiamond switch and another Extreme switch. All

ports on the BlackDiamond switch belong to VLAN Sales. Ports 1 through 29 on the other Extreme

switch also belong to VLAN Sales. The two switches are connected using slot 8, port 4 on system 1 (the

BlackDiamond switch), and port 29 on system 2 (the other switch).

Figure 2: Single port-based VLAN spanning two switches

To create multiple VLANs that span two switches in a port-based VLAN, a port on system 1 must be

cabled to a port on system 2 for each VLAN you want to have span across the switches. At least one

port on each switch must be a member of the corresponding VLANs, as well.

Figure 3 illustrates two VLANs spanning two switches. On system 2, ports 25 through 29 are part of

VLAN Accounting; ports 21 through 24 and ports 30 through 32 are part of VLAN Engineering. On

system 1, all port on slot 1 are part of VLAN Accounting; all ports on slot 8 are part of VLAN

Engineering.
