Checking Low Latency Transport operation

Use the

lltstat

command to verify that links are active for LLT. This command

returns information about the links for LLT for the system on which it is typed.
See the

lltstat

(1M) manual page.

In the following example,

lltstat

-n

is typed on each system in the cluster.

To check LLT operation

Log into system01.

# lltstat -n

Note: Each system has two links and that each system is in the

OPEN

state. An

asterisk (*) denotes the system on which the command is typed.

With LLT configured correctly, the output of

lltstat

-n

shows all of the

systems in the cluster and two links for each system. If the output shows
otherwise, you can use the verbose option of

lltstat

. For example, type

lltstat

-nvv | more

on a system to view additional information about

LLT. In the following example,

lltstat

-nvv

|

more

is typed on a system in

a two-node cluster.
