NTERFACE ONFIGURATION
Use the undo ima ima-group
group.
By default, no IMA group is created.
Before adding an ATM E1/T1 interface to an IMA group, you need to remove the
network layer service-related configurations of the interface. for example, the IP
address assigned to the interface by using the undo ip address command.
n
The first link in the IMA group is the primary link. You can remove it only when
you remove the IMA group.
# Add the link of ATM E1 interface 5/0 to IMA group 1.

IMA group interface view
ctc: Common transmit clock configuration. In this mode, all links in the IMA group
share the same clock source, which can be an external clock or the one extracted
from a member link.
link-number number: Number of the E1/T1 link that provides the clock source. It
ranges from 0 to 7.
itc: Independent transmit clock configuration. In this mode, the links in the IMA
group use at least two clock sources.

When the IMA group adopts ITC mode, you must set the clock mode of each
member ATM E1/T1 link to slave with the clock slave command.
When the IMA group adopts CTC mode, you must set the clock mode of each
member ATM E1/T1 link to master with the clock master command.
# Set the clock mode to ITC on IMA group 1.
