Use the undo frame-format command to restore the default, that is, CRC4
ADM for ATM E1 interfaces and ESF ADM for ATM T1 interfaces.
ATM Direct Mapping (ADM) directly maps ATM cells transmitted over the E1/T1
line into E1/T1 frames. This process is defined by ITU-T G.804 and ATM forum.
Example # Configure no-CRC4 ADM framing on ATM E1 interface 5/0.
<Sysname> system-view
[Sysname] interface atm 5/0
[Sysname-Atm5/0] frame-format no-crc4-adm

Parameter 32, 64, 128, 256: Specifies the number of ATM cells in an IMA frame.
Description Use the
frame-length command to configure the number of ATM cells in an IMA
frame.
Use the
undo frame-length command to restore the default, that is, 128 ATM
cells in an IMA frame.
Example # Set the number of ATM cells in an IMA frame to 64 on IMA group interface 1.
<Sysname> system-view
[Sysname] interface atm 5/0
[Sysname-Atm5/0] ima ima-group 1
[Sysname-Atm5/0] interface ima-group 5/1
[Sysname-Ima-group5/1] frame-length 64
ima ima-group
Syntax ima ima-group group-number
undo ima ima-group
View ATM E1/T1 interface view
Parameter group-number: IMA group number, in the range 1 to 8.
Description Use the
ima ima-group command to add an ATM E1/T1 interface to an IMA
group. If the specified IMA group does not exist, it is created first.
