GP-L200MP User Manual

Appendix C About QoS

PLC 200AV allows for 4 levels of Channel Access Priority (CAP (0 – 3)). The 8 levels

of VLAN Ethernet tags must be mapped to the 4 levels of CAP priority, where CAP 3

is the highest priority and CAP 0 is the lowest. CAP 3 priority might be used for voice

and network management frames, and CAP 2 is used for streaming video and music

while CAP 1 and CAP 0 are used for data.

Default CAP

The ‘Default CAP’ group allows for default priority mapping of packets that do not

have a VLAN TAG. The settings are available for Unicast (directed to a host).

IGMP - (default CAP 3) - sets the channel access priority for IGMP

frames - these are the group management frames, not the stream data.

Unicast - (default CAP 1) - sets the default channel access priority for

unicast frames not matching any other classification or mapping.

IGMP managed Multicast Stream (Fixed to CAP 2) - sets the default

channel access priority for stream data belonging to a snooped IGMP

multicast group.

Multicast/Broadcast - sets the default CAP for multicast frames not in a

snooped group and for broadcast frames.
