Sometimes default values under the configuration may not still be present,
or visible.
So according the following test, it looks like "no frame-relay adaptive
shaping becn" is the default:
r5(config)#map-class frame-relay TEST
r5(config-map-class)#frame-relay cir 800000
r5(config-map-class)#frame-relay mincir 128000
r5#show run
map-class frame-relay TEST
frame-relay cir 800000
frame-relay mincir 128000
now adding the becn adaptive shaping command
r5(config-map-class)#frame-relay adaptive-shaping becn
r5#show run
map-class frame-relay TEST
frame-relay cir 800000
frame-relay mincir 128000
frame-relay adaptive-shaping becn
