To view detailed protocol information:

Step 1 Highlight the packet number about which you want more information.

Detailed information about that packet is displayed in the Protocol Decode and hexadecimal dump panes at the bottom of the window.

Note If you highlight the details in the Protocol Decode pane, the corresponding bytes are highlighted in the hexadecimal dump pane below it.

Step 2 To review the information, use the scrolling bar in the lower panes.

Note When you decode SCCP traffic, the NAM lists the protocol as skinny, not SCCP.

Tip	•	Protocols are color coded both in the Packet Browser and the Protocol Decode pane.
