Release 5.2, Part Number OL-6484-01 Rev. C0, September 2005
Chapter 4 AXSM Card Management
Managing IMA Groups
In the example that follows, the user modifies the IMA group 1.16 as follows:
• the minimum number of links that will allow the IMA group to be operating is 16
• the transmitted IMA ID is 255
• the transmitted frame length is 128 megabytes
• maximum differential delay is 276 milliseconds
MGX8850.2.AXSME.a > cnfimagrp 1.16 -min 128 -id 255 -txm 128 -dd 276
MGX8850.2.AXSME.a >
Step 5 Enter a dspimagrp command to verify IMA group configuration changes.
Configuring an IMA Link
Enter the cnfimalnk command as follows to add one or more lines to an IMA group:
cnfimalnk -lnk <link>, -uplif <lifUpTime>, -dnlif <lifDnTime>, -uplods <lodsUpTime>,
-dnlods <lodsDnTime>
Table 4-15 describes the parameters for the addlns2imagrp command.
In the following example, the user modifies the IMA link 1.1 to have an LIF integration up time, LIF
integration down time, LODS integration up time, and LODS integration down time of 20,000
milliseconds.
M8850_LA.12.AXSME.a > cnfimalnk -lnk 1.1 -uplif 20000 -dnlif 20000 -uplods 20000
-dnlods 20000

Table 4-15 Parameters for addlns2imagrp Commands
Parameter Description
link The bay number (1–2) and the IMA link number (1–16) in the format bay.link.
For example: 1.16
lifUpTime Loss of IMA Frame (LIF) integration up time. Range: 0–400000 milliseconds.
The LIF defect is the occurrence of persistent OIF (Out of IMA Frame)
anomalies for at least 2 IMA frames.
lifDnTime Loss of IMA Frame (LIF) integration down time. Range 0–100000
milliseconds. The LIF defect is the occurrence of persistent OIF (Out of IMA
Frame) anomalies for at least 2 IMA frames.
lodsUpTime Link Out of Delay Synchronization (LODS) integration up time. Range:
0–400000 milliseconds. The LODS is a link event indicating that the link is not
synchronized with the other links within the IMA group.
lodsDnTime Link Out of Delay Synchronization (LODS) integration down time. Range
0–100000 milliseconds. The LODS is a link event indicating that the link is not
synchronized with the other links within the IMA group.
