Configuring Slots and Ports on a Switch

Load-Sharing Examples

This section provides examples of how to define load sharing, or link aggregation, on modular switches.
Cross-Module Load Sharing on a Modular Switch
The following example defines a load-sharing group that contains ports 9 through 12 on slot 3, ports 7
through 10 on slot 5, and uses the port 9 in the slot 3 group as the primary logical port:
enable sharing 3:9 grouping 3:9-3:12, 5:7-5:10
In this example, logical port 3:9 represents physical ports 3:9 through 3:12 and 5:7 through 5:10.
When using load sharing, you should always reference the primary logical port of the load-sharing
group (port 3:9 in the previous example) when configuring or viewing VLANs. VLANs configured to
use other ports in the load-sharing group will have those ports deleted from the VLAN when load
sharing becomes enabled.
Address-based load sharing can also span modules.
Single-Module Load Sharing on a Modular Switch
The following example defines a load-sharing, or link aggregation, group that contains ports 9 through
12 on slot 3 and uses the first port as the master logical port 9:
enable sharing 3:9 grouping 3:9-3:12
In this example, logical port 3:9 represents physical ports 3:9 through 3:12.

Displaying Switch Load Sharing

To verify your configuration, use the following command:
show ports sharing
The following is an example of the display you see when you display load sharing, or link aggregation,
on the BlackDiamond 10K switch:
