Parameters
group-number: IMA group number in the range of 1 to 8.
Usage guidelines
Before adding an ATM E1/T1 interface to an IMA group by using the ima ima-group command, remove
network layer service-related configurations on the interface. For example, remove the IP address
assigned to the interface by using the undo ip address command.
You can remove the first link assigned to an IMA group only after all the other links in the IMA group are
removed. Removing this link also removes the IMA group.
Examples
# Add ATM E1 interface 1/0 to IMA group 1.
<Sysname> system-view
[Sysname] interface atm 1/0
[Sysname-Atm1/0] ima ima-group 1
ima-clock
Use ima-clock to configure the clock mode of the IMA group.
Use undo ima-clock to restore the default.
Syntax
ima-clock { ctc [ link-number number ] | itc }
undo ima-clock
Default
The clock mode is CTC.

Parameters
ctc: Specifies the common transmit clock mode. 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: Specifies the number of an E1/T1 link that provides the clock source. The value
range for the number argument is 0 to 7.
itc: Specifies the independent transmit clock mode. In this mode, the links in the IMA group use at least
two clock sources.
