•Set port 3 to be a member of VLAN 10 and VLAN 20; and don’t change default PVID (=1) for both switches.
•Leave port 1 and port 2 are untagged (untag) ports for both switches.
•Set port 3 to be a tagged (tag) port for both switches.
•Generate untagged packets from TG port 1 and port 2.
EXPECTED RESULT: Tracs are segregated between VLAN 10 & VLAN 20. TG port 3 only receives untagged packets from TG
port 1; and TG port 4 only receives untagged packets from TG port 2.

Test Network Topology
2. TG sends tagged packets to switch and receive untagged packets from switch.Connect TG port 1 to Switch A port 1.
•Use the same test environment as #1.
•From TG port 1, generate tagged packets with VLAN ID = 10.
•From TG port 2, generated tagged packets with VLAN ID = 20
EXPECTED RESULT: Tracs are segregated between VLAN 10 & VLAN 20. TG port 3 only receives untagged packets from TG
port 1; and TG port 4 only receives untagged packets from TG port 2.
3. TG sends untagged packets to switch and receive tagged packets from switch.
•Use the same test environment as 1, except Switch B’s port 1 and port 2 configurations.
•Change Switch B port 1 and port 2 to “tag” port.
•From TG port 1 and port 2, send untagged packets to Switch A.
EXPECTED RESULT: Tracs are segregated between VLAN 10 & VLAN 20. TG port 3 only receives tagged packets (with VLAN
ID 10) from TG port 1; and TG port 4 only receives tagged packets (with VLAN ID 20) from TG port 2.
4. TG sends tagged packets to switch and receive tagged packets from switch.
•Use the same test environment as 3.
•From TG port 1, send tagged packets with VLAN ID 10 to Switch A.
•From TG port 2, sends tagged packets with VLAN ID 20 to Switch A.
EXPECTED RESULT: Tracs are segregated between VLAN 10 & VLAN 20. TG port 3 only receives tagged packets (with VLAN
ID 10) from TG port 1; and TG port 4 only receives tagged packets (with VLAN ID 20) from TG port 2.
QoS
ProSAFE Plus Gigabit Switches support 4 priority level queues. The queue service rate is based on the Weighted Round Robin (WRR)
algorithm. The weight ratio of high-priority and low-priority queue is 4:1 for Fast Ethernet models, 24:8:2:1 for gigabit models ,
and 8:4;2:1 for 10G model.
