• When a channel is deleted from an IMA group, it is recommended that a deletion
take place at the far end first if the far end supports graceful deletion. This is to
ensure no cell loss takes place on the 7705 SAR Rx end of the channel. When a
channel is deleted on the 7705 SAR end first, a small data loss will take place on the
7705 SAR Rx side (depending on the time required for the far end to deactivate its
Tx on the link being deleted).
• If no member links are configured on an IMA group, the speed of an E1 channel will
be used to compute the maximum IMA group bandwidth that may be allocated to
shaped services.
• 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 group with three group members
residing on a channelized 16-port T1/E1 ASAP Adapter card in slot 1/3/1:
ALU-A>config# port bundle-ima-1/3.1
ALU-A>config>port# multilink-bundle
ALU-A>config>port>ml-bundle# member 1/3/1.1
ALU-A>config>port>ml-bundle# member 1/3/2.1
ALU-A>config>port>ml-bundle# member 1/3/3.1
IMA Test Procedure
Use the following CLI syntax to perform an IMA Test Pattern Procedure on a member link
of an IMA group.
CLI Syntax: configure# port bundle-ima-slot/port.bundle-num
multilink-bundle
ima
test-pattern-procedure
test-link port-id
test-pattern [pattern]
no shutdown
An operator can deploy IMA test procedures to verify operations of an IMA group and its
member links. The following is a list of key points about the test pattern procedure.
1. The test procedure is performed as defined by the IMA specification version 1.1.
That is, a test pattern is sent over the specified link and is expected to be looped back
over all the links in the group. ICP cells are used to perform the test.
2. The test procedure is not traffic-affecting; that is, data traffic will not be affected by
the ongoing test.
3. There can only be a single test executed per IMA group at any given time.
4. The IMA member link must exist in the specified group for the command to be
accepted.
