Configuring Expand-Over-IP Lines
Expand Configuration and Management Manual—523347-008

Profile Modifiers
Example 8-13 shows how to add an Expand line from \NodeC to \NodeB.
Profile Modifiers
This subsection lists the recommended modifiers for single-line Expand-over-IP
line-handler processes and describes the modifiers provided for configuring special
features. It also describes default values and value ranges for all the modifiers
contained in the PEXQSIP profile.
Recommended Modifiers
Recommended modifiers are modifiers that should be used to obtain optimum
performance and efficiency.
L4CONGCTRL_ON
Default: ON for single-line paths, OFF for multi-line paths (because it is shared by all
line types)
Units: Not applicable
Range: ON or OFF
This modifier enables the congestion control mechanism. Because data transfer with
the UDP is not guaranteed, the Expand End-to-End protocol is used to achieve reliable
communications for Expand-over-IP connections. You can avoid congestion and
improve error recovery by using the L4CONGCTRL_ON modifier.
Example 8-13. Add an Expand Line to \NodeB
allow all errors
abort line $giplba1
stop device $zzwan.#giplba1
delete device $zzwan.#giplba1

Note. A different profile is provided for Expand-over-IP lines that are part of a multi-line path;
this profile is described in Section 14, Configuring Multi-Line Paths
