The above sample configuration specifies that any frames on VLAN2, VLAN3 and VLAN4
will be processed or have their PCP value adjusted according to QoS values set.
VLAN1
•
VLAN1 is an untagged VLAN so there are no 802.1Q tags on the frames.
VLAN2
•
Any frames received on VLAN2 destined to VLAN2 with PCP priority of 1 will be
forwarded without altering the priority; it will be still set to 1.
•
Any frames received on VLAN2 destined to VLAN2 with a PCP priority set to 0 will
have a priority of 1 set as they leave the router on VLAN2.
VLAN3
•
Any frames received on VLAN3 destined to VLAN3 with a PCP priority of 3 will be
forwarded without altering the priority; it will be still set to 3.
•
Any frames received on VLAN3 destined to VLAN2 with PCP priority set to 0 will
have a priority of 3 set as they leave the router on VLAN3.
VLAN4
•
Any frames received on VLAN4 destined to VLAN2 with PCP priority of 5 will be
forwarded without altering the priority; it will be still set to 5.
•
Any frames received on VLAN4 destined to VLAN2 with PCP priority set to 0 will
have a priority of 5 set as they leave the router on VLAN4.
