6.8 Link Aggregation
6.8.1 Static Trunk
Link Aggregation (Trunking) is the grouping of physical ports into one logical higher-capacity
link. You may want to trunk ports if for example, it is cheaper to use multiple lower-speed links
than to under-utilize a high-speed, but more costly, single-port link.
However, the more ports you aggregate then the fewer available ports you have. A trunk group
is one logical link containing multiple ports. The Switch supports both static and dynamic link
aggregation.
Note: In a properly planned network, it is recommended to implement static link aggregation
only. This ensures increased network stability and control over the trunk groups on your Switch.
6.8.1.1 CLI Configuration
The command displays the current trunk
configurations.
This command changes the node to
configure node.
link-aggregation [GROUP_ID]
(disable | enable)
The command disables / enables the trunk
on the specific trunk group.
link-aggregation [GROUP_ID]
load-balance (mac|ip)
The command configures the load balance
algorithm for the trunk group.
link-aggregation [GROUP_ID]
interface PORTLISTS
The command adds ports to a specific
trunk group.
no link-aggregation [GROUP_ID]
interface PORTLISTS
The commands delete ports from a
specific trunk group.
Example:
L2SWITCH#configure terminal
L2SWITCH(config)#link-aggregation 1 enable
L2SWITCH(config)#link-aggregation 1 ports 1-4
