On a frame relay port, the C/R, FECN,BECN, and DE bits will be displayed separately, then the remainder of eachframe will be displayed as data.Q Enables/disables display of QData packets.R Enables/disables display of Restart/Reset packets on an X.25 port, or LMIDLCI information on a frame relay port. (Only the sequence numbers will bedisplayed for Link Integrity Verification messages on a frame relay port.)T Enables/disables timestamps and lengths of packets.2 Enables display of all LAPB level 2 frames (if appropriate to the port).3 Changes LAPB display (see 2 above) back to level 3.
