Aggregated Links
Aggregated links are connections that allow devices to communicate
using up to two links in parallel. Aggregated links are supported on the
10/100/1000BASE-T ports only
.
These parallel links provide two benefits:
■
They can potentially double the bandwidth of a connection.
■
They can provide redundancy — if one link is broken, the other link
can share the traffic for that link.
Figure 1
shows two Switches connected using an aggregated link
containing two member links. If the ports on both Switch units are
configured as 1000BASE-T and they are operating in full duplex, the
potential maximum bandwidth of the connection is 2 Gbps.

Aggregated Links and
You r Swi tch
Each Switch supports up to two aggregated links. Each aggregated link
can support up to two member links.
When setting up an aggregated link, note that:
■
The ports at both ends of a member link must be configured as
members of an aggregated link.
■
A member link port can only belong to one aggregated link.
■
The member link ports can have different port configurations within
the same aggregated link, that is, auto-negotiation, port speed, and
duplex mode. However, please note the following:
■
To be an active participant in an aggregated link the member link
ports must operate in full duplex mode. (If a member link port does
not operate in full duplex mode it can still be a member of an
aggregated link but it will never be activated.)
