 Aging Time: This command allows user to disable the feature or configure the
aging timeout time to 200ms, 400ms, 600ms or 800ms.
 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
