show ports sharing
Description
Displays port load-sharing groups, or link aggregation groups (LAGs).
Syntax Description
This command has no arguments or variables.
Default
N/A.
Usage Guidelines
Output from this command displays the following information:
- Config Master—The port that is configured as the master logical port of the link aggregation group (LAG). This number is also the LAG group ID.
- Current Master—In LACP, this is the port that is currently the LAG group ID, or master logical port for the LAG.
- Agg Control—This is the aggregation control for the specified LAG; it can be either static, LACP or health-check. In LACP, it is the aggregation control for the specified LAG.
- Min Active—The minimum number of active links that must be up for the trunk to remain up.
- Ld Share Algorithm—The algorithm used for the link aggregation. The available link aggregation algorithms vary among platforms; see the ExtremeXOS 22.1 User Guide for more information.
- Ld Share Group—The specific ports that belong to each LAG, or the port numbers in the trunk. A port can belong to only one LAG, either static or dynamic.
- Agg Mbr—In LACP, this shows whether the port has been added to the aggregator or not; it will be either Y for yes or - for no.
- Link State—This is the current status of the link.
- Link Up transitions—Number of times the link has cycled through being up, then down, then up.
- LAG distribution mode—Displays the configured distribution mode and distribution port lists for LAGs.
Example
Following is sample output displaying link aggregation on a Summit series switch:
