4.3.4 Port Trunking
Port Trunking configuration allows you to group multiple Ethernet ports in parallel
to increase link bandwidth. The aggregated ports can be viewed as one physical
port so that the bandwidth is higher than merely one single Ethernet port. The
member ports of the same trunk group can balance the loading and backup for
each other. Port Trunking feature is usually used when you need higher
bandwidth for backbone network. This is an inexpensive way for you to transfer
more data.
There are some different descriptions for the port trunking. Different
manufacturers may use different descriptions for their products, like Link
Aggregation Group (LAG), Link Aggregation Control Protocol, Ethernet Trunk,
Ether Channel…etc. Most of the implementations now conform to IEEE standard,
802.3ad.
The aggregated ports can interconnect to the other switch which also supports
Port Trunking. Westermo Supports 2 types of port trunking. One is Static Trunk,
the other is 802.3ad. When the other end uses 802.3ad LACP, you should assign
802.3ad LACP to the trunk. When the other end uses non‐802.3ad, you can then
use Static Trunk.
There are 2 configuration pages, Aggregation Setting and Aggregation Status.
Aggregation Setting
Trunk Size: The switch can support up to 8
trunk groups with 2 trunk members. Since
the member ports should use same
speed/duplex, max trunk members for
100Mbps would be 8, and 2 for gigabit.
Group ID: Group ID is the ID for the port
trunking group. Ports with same group ID
are in the same group.
Type: Static and 802.3ad LACP. Each Trunk
Group can only support Static or 802.3ad
LACP. Choose the type you need here.
Aggregation Status
This page shows the status of port aggregation. Once the aggregation ports are
negotiated well, you will see following status
.
