Link Aggregation on the Switch
ExtremeWare XOS 11.3 Concepts Guide

● Dynamic link aggregation—LACP
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 Summit X450 switch:
Load Sharing Monitor
Config Current Agg Ld Share Ld Share Agg Link Link Up
Master Master Control Algorithm Group Mbr Status transitions
==============================================================================
5 5 LACP L2 5 Y A 3
L2 6 Y A 3
L2 7 Y A 3
L2 8 Y A 3
L2 9 - A 3
L2 10 - A 3
12 Static L2 12 - R 0
L2 13 - R 0
===========================================================================
Link Status: A-Active, D-Disabled, R-Ready, NP-Port not present
Load Sharing Algorithm: (L2) Layer 2 address based, (L3) Layer 3 address based
Default algorithm: L2
Number of load sharing trunks: 2
NOTE
The Agg Mbr column displays which ports in the LACP LAG are added to the aggregator at the hardware level. Only
those ports that are added to the aggregator actually send and receive traffic. The Y means the port is added to the
aggregator.
To verify LACP configuration, issue the following command:
show lacp
The following is an example of the output you see when you display the LACP information on the
modular switch:
LACP Up : Yes
LACP Enabled : Yes
System MAC : 00:04:96:10:33:60
LACP PDUs dropped on non-LACP ports : 0
Lag Actor Actor Partner Partner Partner Agg
Sys-Pri Key MAC Sys-Pri Key Count

4:9 677 0x0fa9 00:01:30:f9:9c:30 87 0x0fa9 8
To display information for the specified LAG, issue the following command:
show lacp lag <group-id> {detail}
The following is an example of the output you see when you display the LACP information for this
command on a modular switch:
