16 Compex 24-Port + 1 Expansion Slot Switch
SAS2224B
English
VLAN Function:
Normally, any broadcast/multicast and unicast packet all not allowed switching between
VLANs. For example, Port 1 broadcast packet will only flood to port 2 and 3, and port 1
unicast packet is not allowed to forward to any member of another VLAN.
If the leaky VLAN function is enabled, 3 types of specific frame could be forward to
different VLAN destination port:
♦ Unicast packet leaky control
♦ ARP broadcast leaky control
♦ IP multicast leaky control
These 3 types of leaky control are useful for a switch to be broken into many VLANs
and want to enable a host-to-host communication between different VLANs without any
router or with router but improve the router performance.
Unicast Packet Inter-VLAN Leaky:
Unicast is a term to describe the communication in the network that packets are being
sent out from one point to another point.
Upon enabling this option, Compex SAS2224B allows the packet to be forwarded to a
destination port at different VLAN.
ARP broadcast Packet Inter-VLAN Leaky:
ARP broadcast refers to the ARP packets that are being sent out from one point to all
connected points in the network.
Upon enabling this option, Compex SAS2224B allowed ARP frame to be broadcasted
to all switch ports.
IP Multicast Packet Inter-VLAN Leaky:
IP multicast provides dynamic many-to-many connectivity between a set of senders (at
least 1) and a group of receivers.
Upon enabling this option, Compex SAS2224B allows the IP multicast packet to be
flooded to all multicast address group members.
