Advanced Link Aggregation Troubleshooting
To verify that the link aggregate software recognizes all the available slices, perform the following steps:
Note. Dshell commands should only be used by Alcatel personnel or under the direction of Alcatel.
Misuse or failure to follow procedures that use Dshell commands in this guide correctly can cause lengthy
network down time and/or permanent damage to hardware.
1 Use the lagg_Sock_cmm_boardupprint Dshell command, which displays all Network Interface (NI)
modes that are currently operating.
2 Verify that all NIs are present in the output.

LAGG boards up :
board in slot : 2 slice : 0 is up
board in slot : 5 slice : 0 is up
board in slot : 6 slice : 0 is up
board in slot : 7 slice : 0 is up
board in slot : 8 slice : 0 is up
value = 0 = 0x0

To view the status of all ports and weather they are part of an aggregate use the la_pm_port_prt Dshell
command, which displays the the status of port mirroring and whether any ports are part of a link aggrega-
tion group. Note that status=2 indicates that port is part of an aggregate.

To display an aggregate’s configuration use the command la_cmm_agg_prt Dshell command. This will
display the aggregate as well as the individual ports that are configured. Note the ifindex as it will be
needed.
