Remark:
1. A packet is dropped if the time it stays in output queue is more than the configured Aging time. "Disable"
setting forces a packet never aged out.
2. VLAN Striding
In normal case, a uni-cast packet is not allowed to be forwarded to a port not in a VLAN member port list
and the uni-cast is dropped. "Enable" VLAN Striding allows the uni-cast packet to be forwarded cross a
VLAN. That means uni-cast packets are forwarded as no VLAN limitation.
3. IGMP Snooping
When this function is enabled, the switch will monitor multicast router ports and maintain IP multicast
group information. The switch also listens on IGMP messages to maintain the associated member ports of
each multicast group. Multicast packets are forwarded only to the group's member ports. The ports not in
the member list are not affected by the multicast traffic.
4. VLAN Uplink Ports
With VLAN uplink enabled, a packet which is filtered in a VLAN is forwarded to VLAN uplink ports instead.
The VLAN uplink port must be a member of the same VLAN. Two VLAN uplink ports can be designated,
one port in one VLAN. "Clear" option is to disable uplink forwarding.
