GS728TS, GS728TPS, GS752TS, and GS752TPS Gigabit Smart Switches
To configure global flow control settings:
1. From the Global Flow Control (IEEE 802.3x) Mode field, enable or disable IEEE 802.3x
flow control on the system. The factory default is Disable.
• Enable. The switch sends pause packets if the port buffers become full.
• Disable. The switch does not send pause packets if the port buffers become full.
2. Click Cancel to cancel the configuration on the screen and reset the data on the screen to
the latest value of the switch.
3. If you change the mode, click Apply to apply the changes to the system.
Link Aggregation Groups
Link aggregation groups (LAGs), which are also known as port-channels, allow you to
combine multiple full-duplex Ethernet links into a single logical link. Network devices treat the
aggregation as if it were a single link, which increases fault tolerance and provides load
sharing. You assign the LAG VLAN membership after you create a LAG. By default, the LAG
becomes a member of the management VLAN.
A LAG interface can be either static or dynamic, but not both. Dynamic LAGs use Link
Aggregation Control Protocol (LACP) Protocol Data Units (PDUs) to exchange information
with their link partners to help maintain the link state. A static port-channel interface does not
require a partner system to be able to aggregate its member ports. When a port is added to a
LAG as a static member, it neither transmits nor receives LACP PDUs.
The GS728TS, GS728TPS, GS752TS, and GS752TPS Smart Switches each support four
LAGs.
From the LAGs link, you can access the following pages:
• LAG Configuration on page 105
• LAG Membership on page 107
• LACP Configuration on page 108
• LACP Port Configuration on page 109
LAG Configuration
Use the LAG (Port Channel) Configuration page to group one or more full-duplex Ethernet
links to be aggregated together to form a link aggregation group, which is also known as a
port-channel. The switch treats the LAG as if it were a single link.
To access the LAG Configuration page, click Switchingï€ > LAG > Basic > LAG Configuration.
