Link Aggregation on the Switch

commands. It can be thought of as the logical port representing the entire port group, and it serves as
the LAG Group ID.
To create a LAG for LACP, issue the following command, take the following steps:
1 Create a LAG, using the following command:
enable sharing <port> grouping <port_list> {algorithm [port-based | address-based {L2|L3}]} {lacp}
The port you assign using the first parameter becomes the logical port for the link aggregation group
and the LAG Group ID when using LACP. This logical port must also be included in the port list of
the grouping itself.
2 If you wish to override the default prioritization in LACP for a specified LAG, issue the following
command:
configure sharing <port> lacp system-priority <priority>
This step is optional; LACP handles prioritization using system MAC addresses.
3 Add or delete ports to the LAG as desired, using the following commands:
configure sharing <port> add ports <port_list>
configure sharing <port>
delete ports <port_lis

NOTE
Always verify the LACP configuration by issuing the show ports sharing command; look for the ports listed as being
in the aggregator.
Configuring LACP on BLackDiamond 8800 Family of Switches and Summit X450 Switch. The following rules
apply to the number of LACP ports in one LAG on the BlackDiamond 8800 family of switches and on
the Summit X450 switch:
â—Ź Up to 16 link per LAG
â—Ź Up to 8 selected links and 8 standby links
â—Ź Only address-based LACP algorithm
Configuring LACP on BLackDiamond 10K Series of Switches. The following rules apply to the number of
LACP ports in one LAG on the BlackDiamond 10K series of switches:
â—Ź Up to 32 link per LAG
â—Ź Up to 16 selected links and 16 standby links
â—Ź Cannot specify L2 or L3 address-based LACP algorithm
Load-Sharing Examples
This section provides examples of how to define load sharing, or link aggregation, on stand-alone and
modular switches, as well has defining dynamic link aggregation.
Load Sharing on a Stand-alone Switch
The following example defines a static load-sharing group that contains ports 9 through 12, and uses
the first port in the group as the master logical port 9:
enable sharing 9 grouping 9-12
