Westermo OS Management Guide
Version 4.17.0-0
The next subsections provide additional information on WeOS support for link
aggregates:
(static) and
(LACP) contain information on
the methods to control link aggregates in WeOS, while
include
more details on using link aggregates in various low-layer features in WeOS.
17.1.2
Static Link Aggregates
For static link aggregates the including member ports are the only settings that
have to be specified in the configuration. The members in an aggregate do not
need to have the same speed settings, although that is the preferred setting
(otherwise the capacity of the aggregate will be unbalanced).
Ports that are included in an aggregate and have link up will be qualified as active
ports, and the network traffic will be sent on those links. If a link goes down or up
in the aggregate the network traffic will be distributed over the new set of active
links. Because an active link in an aggregate is qualified on the link status no
media converters are allowed between statically aggregated ports. Below is a
CLI configuration example where the static link aggregate a1 is configured with
member ports 3 and 7 on a WeOS switch.
Example
example:/#> configure
example:/config/#> aggregate a1
example:/config/aggregate-a1/#> ports 3,7
example:/config/aggregate-a1/#> type static
example:/config/aggregate-a1/#> show
Name
: a1
Status
: Enabled
Type
: static
Ports
: 3,7
example:/config/aggregate-a1/#> end
example:/config/#>
17.1.3
LACP Controlled Link Aggregates
The Link Aggregation Control Protocol (IEEE 802.3ad/802.1AX [
]) is a standard
method for aggregating member links that have the same speed and duplex
mode. The primary advantage over static link aggregation is the ability to confirm
that the remote partner can handle aggregation. It is also possible to handle
failover when media converters are present.
