I could get some information using layer2info as shown below.

# echo "/layer2info interface"|nc 127.0.0.1 2009
wlan1    74    02:00:00:00:01:00                    2.412 GHz    0 Hz    
20 MHz    0  Hz

I used the following configuration entries.

dlep_radio.conf
===============
[global]
         plugin          dlep_radio
         plugin          layer2info
         plugin          nl80211_listener

[dlep_radio=tap0]
         source          wlan1

[nl80211_listener]
         if              wlan1
         interval        1.0

[layer2_viewer]

I am not sure whether layer2_viewer is in effect or not. Because, when I 
tried "olsrd2_static --set global.plugin=layer2_viewer 
--schema=layer2_viewer" to know the plugin options, I got the following 
message,

WARN(plugins) src-api/core/oonf_subsystem.c 544: Loading of plugin 
layer2_viewer failed.
Unknown section type 'layer2_viewer'
