Usage guidelines
The MTU only influences the packet assembly and disassembly at the IP layer at the ATM interface. Due
to the limit of QoS queue length, MTU that is too small might cause numerous fragments. Thus, it might
be dropped by the QoS queue. The length of the QoS queue can be increased appropriately. The default
queue dispatching mechanism used by PVC is FIFO. You can use the qos fifo queue-length command in
the PVC view to change its queue length.
This command applies to ATM main interface and subinterface simultaneously.
Examples
# Set the MTU to 1492 bytes for interface ATM 1/0.
<Sysname> system-view
[Sysname] interface atm 1/0
[Sysname-Atm1/0] mtu 1492
