Decodes

The Agilent Advisor provides the ability to decode correlated Frame Relay

network traffic with its enhanced decode view. Decodes can be configured to

see: Summary of the frame, detailed decode of the frame, and a hex

representation of the frames as depicted in figure 17.

The analyzer decodes and displays the following fields and protocols:

• DLCI, DE, FECN, BECN, E/A and FCS

• Auto LMI detection and decoding for ANSI T1.617 Annex D, ITU-T Q.933

Annex A, original LMI

• Consolidated Link Layer Management (CLLM) messages, found on DLCI

1007.

• Multi-Protocol over Frame Relay (Network Layer)

• The Frame Relay applications will decode the multi-protocol encapsulation

over Frame Relay automatically according to RFC-1490, RFC-2427, Ethertype

or FRF.3.1, CLLM, and Annex G (X.25 over Frame Relay).

• Voice over Frame Relay (VoFR) monitoring FRF.11

• Committed Information Rate according to ANSI T1.606a

Double clicking on a field in the Detailed Pane of the decode Window will

cause the appropriate fields in the Hex decode pane to be inverse highlighted

giving the user greater analysis capabilities in the decode view.
