Configuring Slots and Ports on a Switch
ExtremeWare XOS 11.3 Concepts Guide
126
In this example, logical port 9 represents physical ports 9 through 12.
When using load sharing, you should always reference the master logical port of the load-sharing group
(port 9 in the previous example) when configuring or viewing VLANs; the logical port serves as the
LAG Group ID. VLANs configured to use other ports in the load-sharing group will have those ports
deleted from the VLAN when load sharing becomes enabled.
Cross-Module Load Sharing on a Modular Switch
The following example defines a static load-sharing group on modular switches 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, or LAG Group ID:
enable sharing 5:7 grouping 3:9-3:12, 5:7-5:10
In this example, logical port 5:7 represents physical ports 3:9 through 3:12 and 5:7 through 5:10.
When using load sharing, you should always reference the LAG Group ID 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 static 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, or LAG group ID:
enable sharing 3:9 grouping 3:9-3:12
In this example, logical port 3:9 represents physical ports 3:9 through 3:12.
LACP Example
The following configuration example:
â—Ź Creates a dynamic LAG with the logical port (LAG Group ID) of 10 that contains ports 10 through
12.
â—Ź Sets the system priority for that LAG to 3.
â—Ź Adds port 5 to the LAG.
enable sharing 10 grouping 10-12 lacp
configure sharing 10 lacp system-priority 3
configure sharing 10 add port 5
Displaying Switch Load Sharing
Beginning with ExtremeWare XOS version 11.3, you can use either static or dynamic load sharing (link
aggregation). LACP is used to create, configure, and display dynamic link aggregation. In the link
aggregation displays, the types are shown by the following aggregation controls:
● Static link aggregation—static
