Q in Q
1. Port-based Q in Q
2. Add SVLAN tag to either untagged or single tagged packets and
generate double tagged packets
3. Support Selective Q-in-Q. Add SVLAN tag based on
- PVID (for untagged packets only)
- CVLAN tag
4. Support untagged / single tagged / double tagged at same
physical port
UNI Port:
 For packets ingress from UNI port, the packet can be
untagged, or CVLAN tagged
 Based on user configuration, SVLAN tag can be added
to the packet, or CVLAN tag be replaced with SVLAN
tag
 The learning and forwarding is based on SVLAN.
NNI Port:
 For packets ingress from NNI, it can be untagged, or
single SVLAN tagged, or double tags. The switch's
learning and forwarding is based on SVLAN.
(CVLAN tag is identified by CVALN TPID. SVLAN tag is
identified by SVLAN TPID.)
5. Per port configurable SVLAN TPID
6. Support up to 4 SVLAN TPID ( Per port & per system)
7. Per system configurable CVLAN TPID

FCS
IGMP Snooping
1. Support IGMP snooping v1, v2, v3
2. 1K IGMP snooping groups;
3. Support 64 static multicast addresses;
4. Can configure a port as a static router port, or can forbid a port
to be learnt as a router port.
5. Per VLAN IGMP Snooping
8. Support Host-based IGMP Fast Leave
9. IGMP Snooping Report Suppression: When IGMP report
suppression is enabled, the switch sends the first IGMP report
from all hosts for a group to all the multicast routers. The
switch does NOT send remaining IGMP reports for the group to
the multicast routers. This feature prevents duplicate reports
from being sent to the multicast devices.
10. Support IGMP messages rate limit per port / per VLAN
11. Support snooping counter
13. Support snooping switches (RFC4541)
RFC2236,
3376, 4541 FCS
