show ports sharing

show ports port_list sharing distribution configuration


Displays port load-sharing groups, or LAG (Link Aggregation Group)s.

Syntax Description

This command has no arguments or variables.



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 22.2 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.

Minimum Active: (<) Group is down. # active links less than configured minimum
Load Sharing Algorithm: (L2) Layer 2 address based, (L3) Layer 3 address based
                        (L3_L4) Layer 3 address and Layer 4 port based
                        (custom) User-selected address-based configuration

Custom Algorithm Configuration: ipv4 L3-and-L4, xor
Number of load sharing trunks: 2
