Configuring VLAN Trunks

Load Sharing on Trunk Ports

Figure 4: Load Sharing by Using STP Port Priorities

Trunk 1 carries traffic for VLANs 8 through 10, and Trunk 2 carries traffic for VLANs 3 through 6. If the active trunk fails, the trunk with the lower priority takes over and carries the traffic for all of the VLANs. No duplication of traffic occurs over any trunk port.

Network Load Sharing Using STP Path Cost

You can configure parallel trunks to share VLAN traffic by setting different path costs on a trunk and associating the path costs with different sets of VLANs, blocking different ports for different VLANs. The VLANs keep the traffic separate and maintain redundancy in the event of a lost link.

Trunk ports 1 and 2 are configured as 100BASE-T ports. These VLAN path costs are assigned:

•VLANs 2 through 4 are assigned a path cost of 30 on Trunk port 1.

•VLANs 8 through 10 retain the default 100BASE-T path cost on Trunk port 1 of 19.

•VLANs 8 through 10 are assigned a path cost of 30 on Trunk port 2.

•VLANs 2 through 4 retain the default 100BASE-T path cost on Trunk port 2 of 19.
