• 802.3x Flow Control – if the port is configured in full
duplex mode, a MAC PAUSE packet is sent to
inhibit the flow of packets to the port for a short
amount of time.
• Enable Jamming Signal – if the port is configured in
half duplex mode, a jamming signal is sent for a
short amount of time.
Spanning Tree Protocol
The VH-2402-L3 switch complies with the IEEE 802.1D
Spanning Tree Protocol standard and allows for the
blocking of links between switches that form loops
within the network. When multiple links between
switches are detected, a primary link is established.
Duplicated links are blocked from use and become
standby links. The protocol allows for the duplicate
links to be used in the event of a failure of the primary
link. Once the Spanning Tree Protocol is configured
and enabled, primary links are established and
duplicated links are blocked automatically. The
reactivation of the blocked links (at the time of a
primary link failure) is also accomplished automatically
– without operator intervention.
Port Trunking
Port trunking is used to combine a number of ports
together to make a single high-bandwidth data pipeline.
The participating parts are called members of a Port
Trunking group, with one port designated as the
master port of the group. Since all members of the
Port Trunking group must be configured to operate in
the same manner, the configuration of the master port
is applied to all members of the Port Trunking group.
Thus, when configuring the ports in a Port Trunking
group, you only need to configure the master port.
