In the lab, I configured a Dell PowerConnect 3324 and a 3348 to trunk with each other, carrying 12 VLANs between the two switches. The trunk was configured on one of the gigabit ports of each switch, with VLAN configuration data shared via GVRP. Ports on the switch were assigned to various VLANs, with the two remaining gigabit ports assigned to the same VLAN. Two gigabit-equipped servers were linked to those ports, and throughput testing began.
Gigabytes of data were passed through the switches between systems connected at gigabit and 100 megabit on a continuous basis, and actual throughput was measured with netperf and TTCP on Linux. Tests were run with no ACL or QoS configuration, as well as with 12-line ACLs and rudimentary QoS configurations. VLAN trunking tests were conducted with Cisco Catalyst 2950 series switches.
Switch were configured via the CLI, the Web interface, and Dell’s Network Manager.
