•
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
: Traffics 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.

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
: Traffics 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
: Traffics 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
: Traffics 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.
