Figure 7-7. SDLC Port Statistics
The SDLC Port Statistics window provides the following statistical data:
Invalid LS Addr
The number of frames received by this port with invalid link station (LS)
addresses, expressed as a rate (frames/second).
Dwarf Frames (Received)
The number of frames received by this port which were delivered intact by the
physical layer, but were too short to be legal. A frame is considered to be too short
if it is less than two bytes for a Modulus of 8, or less than three bytes for a
Modulus of 128 (not counting the frame check sequence (FCS)). The number is
expressed as a rate (frames/second).
I-Frames (Received and Transmitted)
The number of I-frames received or transmitted by the SDLC link stations on this
port, expressed as a rate (frames/second).
