show ports sharing

show ports port_list sharing distribution configuration

Description

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

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 30.3 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

Link State: A-Active, D-Disabled, R-Ready, NP-Port not present, L-Loopback
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
Custom Hash Seed: Switch MAC address (0x969BF582)
Number of load sharing trunks: 2
