Configuring Multilink ATM Inverse Multiplexing (IMA) Bundles

IMA bundles are supported on Channelized ASAP MDAs. The bundles aggregate E1 or DS1
ATM channels into a single logical ATM interface.

IMA Bundles

Use the following CLI syntax to configure IMA bundle parameters:
CLI Syntax: configure# port bundle-type-slot/mda.bundle-num
Configuration notes:
An IMA group has common interface characteristics (for example, configuration that applies to a
logical ATM interface either configured via the IMA group context or taken from the primary
link) The following list details those common IMA group interface characteristics:
•
•
•
•
Member links inherit those common characteristics from the IMA group that they are part of and
as long as they are part of an IMA group. Characteristics derived from the primary link (MTU,
interface mode type) can be changed on the primary link only and not on other links in the bundle
or a bundle itself. The primary link is the member which has the lowest ifindex. When a member
is added/deleted the primary member may be changed based on ifIndicies of all member links.
Once a path becomes part of an IMA group logical link, the path ceases to exist as a physical ATM
path interface. This means that:
