Constructing Multipacket Frames
•
If the Layer 2 protocol is a NAM interface, each Expand packet is treated as a
separate NAM message.
•
If the Layer 2 protocol is NETIP, each Expand packet is treated as a separate UDP
frame.
•
If the Layer 2 protocol is NETATM, each Expand packet is treated as a separate
ATM frame.
Figure 18-19 shows how Expand packets are sent over a direct-connect (HDLC)
connection when the multipacket frame feature is not selected.
In Figure 18-19, a message is passed to a direct-connect Expand line-handler process
that requires six Expand packets. The Expand line-handler process sends each packet
in a separate HDLC-type frame.
Figure 18-20 shows how the same message is handled when the multipacket frame
feature is selected.
