Enabling subinterface rate statistics collection on a
serial interface
CAUTION:
Use this function with caution, because it is system resource demanding.
After enabling subinterface rate statistics collection on a serial interface, the device periodically refreshes
the rate statistics for the subinterfaces of the serial interface. You can use the display interface command
to view the rate statistics.
Serial interfaces that support this feature include synchronous serial interfaces and sub-channel serial
interfaces.
To enable subinterface rate statistics collection for a serial subinterface:

Configuring a CE1 interface
A CE1 interface can operate in either E1 mode (also called non-channelized mode) or CE1 mode (also
called channelized mode).
1. A CE1 interface in E1 mode provides 2.048 Mbps data bandwidth and cannot be divided into
timeslots. It has the same logical features as the synchronous serial interface. It supports link layer
protocols such as PPP and FR and the network protocol IP.
2. A CE1 interface in CE1 mode is physically divided into 32 timeslots numbered 0 to 31. Timeslot
0 is used to transmit synchronizing information. All the other timeslots can be randomly bundled
