dresses.
It should be noted that if the cpu port (i.e. the switch port connected to the management workstation)
is disabled, without doubt, the communication link between user and the switch will not proceed
further. It is recommended to locate the link your PC used before disable the port state.
Flow Control
This feature enables or disables the Flow Control function of the port. Flow control can eliminate
frame loss by "blocking" traffic from end stations or segments connected directly to the switch when
its buffers fill. IEEE 802.3x flow control is used for full duplex. Note that flow control should not be
used if a port is connected to a hub.
3.4 VLAN Config
The SGSW-4802 supports Virtual LAN, which logically groups the connection into VLANs for traffic
isolation and security purposes. Both tagged and untagged based VLAN are supported with a total
maximum of 32 groups. Each VLAN group only forwards traffic within its member ports. For tagged
VLAN, each port can be a member of more than one VLAN group and it also supports priority with eight
levels. There is also provision for creating an untagged VLAN, which support a connection with a
legacy untagged port. The VLAN configuration feature also allows you to build, delete and view tagged
/ untagged VLAN groups and setting priority for tagged VLANs. The range of VID starts from 3 to 4091,
as VID 001 and VID 002 is the default for Group 1 and Group 2.
