Figure 2-3 VLAN partitions

VLAN technique can partition a physical LAN into different broadcast domains logically.
Hosts without intercommunication requirements can be isolated by VLAN, so VLAN
partitions improve network security, and reduce broadcast flow and broadcast storm.
The ISCOM2600G-HI series switch complies with IEEE 802.1Q standard VLAN and
supports 4094 concurrent VLANs.

The ISCOM2600G-HI series switch supports VLAN partitions by interface. The
ISCOM2600G-HI series switch has two interface modes: Access mode and Trunk mode. The
method for processing packets for the two modes is shown as below.

 If the VLAN ID of the
packet is equal to the
Access VLAN ID, the
interface will receive the
packet.

If the VLAN ID of the
packet is not equal to the
Access VLAN ID, the
interface will discard the
packet.

 If the VLAN ID of the
packet is equal to the
Access VLAN ID, the
interface will remove the
Tag and send the packet.

If the VLAN ID of the
packet is excluded from the
list of VLANs of which
packets are allowed to pass
by the interface, the
interface will discard the
packet.
