Figure 4-2: Single port-based VLAN spanning two switches
To create multiple VLANs that span two systems 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 systems. At least one port on each BlackDiamond must be a member of the
corresponding VLANs, as well.
Figure 4-3 illustrates two VLANs spanning two switches. On System 1, all ports on slot
1 are part of VLAN Accounting; all port on slot 8 are part of VLAN Engineering. On
System 2, all port on slot 3 are part of VLAN Accounting; all ports on slot 7 are part of
VLAN Engineering.
