Appendix C
About QoS
The SMCHPAV-ETH2 allows 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 is used for voice and network management frames, 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 default priority mapping of packets that do not
have a VLAN tag. Settings are available for unicast (directed to a host).
z
IGMP - (default CAP 3) - set the channel access priority for IGMP frames -
these are the group management frames, not the stream data
z
Unicast - (default CAP 1) - set the default channel access priority for
unicast frames not matching any other classification or mapping.
z
IGMP managed Multicast Stream (Fixed to CAP 2) - set the default
channel access priority for stream data belonging to a snooped IGMP
multicast group.
z
Multicast/Broadcast - set the default CAP for multicast frames not in a
snooped group and for broadcast frames.
The following are the factory default settings for VLAN Tags and TOS Bits:
