VLAN Striding:
Purpose:
For some network environment, the network administrator
probably want to filter undesired broadcast or multicast packet to
enhance the network bandwidth utilization and forward meaningful
unicast to a specific destination. VLAN is a good mechanism to block
broadcast packet, but it can also block the unicast packet
communication between VLANs. To solve this issue, a special
function called “VLAN striding” is designed to achieve this purpose. If
VLAN striding is enabled, the packet will be forwarded to the
destination port directly, the unicast packet can stride across VLAN.
VLAN Striding:
By selecting this function, the switch will forward
uni-cast packets to the destination port, no matter whether destination
port is in the same VLAN.
IGMP Snooping V1 & V2:
Purpose:
A switch will, by default, flood multicast traffic to all ports in a
broadcast domain. Multicast can cause unnecessary load on host
devices by requiring them to process packets they have not solicited.
The IGMP snooping is a feature that allows the switch to listen in on
the IGMP conversation between hosts and routers. By listening (also
known as snooping) to these conversations, the switch maintains a
map of which ports (clients) need which multicast stream (source).
Multicast may be filtered which do not need them, Multicast may be
forwarded only to the IGMP group it joined.
IGMP Snooping:
When this function is enabled, the switch will
execute IGMP snooping version 1 and version 2 without the
intervention of CPU. The IGMP report and leave packets are
automatically handled by the switch. The next setting, IGMP Leave
Packet can be enabled or disabled. After enabled, the Leave packet
will be forwarded to IGMP router ports.
VLAN Uplink:
Purpose:
This switch does not implement Independent VLAN (IVL)
MAC address table, it utilizes VLAN uplink to emulate the function of
IVL. An independent VLAN MAC address table is based on both the
source MAC address and the VLAN. In some application, if the
