Interface Configuration
7750 SR OS Interface Configuration Guide Page 209
• The 7750 supports automatic IMA version changing when the far end IMA group version 
matches the configured version. The group will remain operationally down until one of 
the IMA groups changes version.
• When adding member links to an IMA group, the clock-source of the e1 or ds1 
link must be set to node-timed.
The following example illustrates creation of an IMA bundle with 3 group members residing on a 
channelized OC-3 ASAP MDA in slot 5/2/1:
A:ALA-A>config# port bundle-ima-5/2.1
A:ALA-A>config>port# multilink-bundle
A:ALA-A>config>port>ml-bundle# member 5/2/1.1.1.1
A:ALA-A>config>port>ml-bundle# member 5/2/1.1.2.1
A:ALA-A>config>port>ml-bundle# member 5/2/1.1.3.1
