Question of ipmi command "Set User Access" in phosphor-host-ipmid

[Thomaiyar, Richard Marian]

Hi Tony,

Yes, that's correct. We already support  channel configuration using 
json(channel_config.json under phosphor-ipmi-config), and sync channel 
can be identified by the first LAN medium channel number - else we can 
add one more configuration as well).

I am ok if you want to go ahead and fix it, else will try to fix the 
same in couple of weeks.

Regards,

Richard
