Figure 7. 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 8 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 ports on slot 1 are part of VLAN Accounting; all ports on slot 8
are part of VLAN Engineering.
Figure 8. Two Port-based VLANs Spanning Two Switches
VLAN Accounting spans system 1 and system 2 by way of a connection between system 2,
port 29 and system 1, slot 1, port 6. VLAN Engineering spans system 1 and system 2 by way
of a connection between system 2, port 32, and system 1, slot 8, port 6.
Using this configuration, you can create multiple port-based VLANs that span multiple
switches, in a daisy-chained fashion. Each switch must have a dedicated port for each VLAN.
Each dedicated port must be connected to a port that is a member of its VLAN on the next
switch.
