Displaying And Maintaining Serial Interfaces; Configuring A Ce1 Interface - H3C SR6602-X Configuration Manual

Step
3. Enable subinterface rate
statistics collection on the
serial interface.

Displaying and maintaining serial interfaces

Execute display commands in any view and reset commands in user view.
Task
Display serial interface information.
Clear statistics for serial interfaces.

Configuring a CE1 interface

The following TDM systems are available in the data communications system:
•
E1 system—Recommended by ITU-T and widely used in Europe and China.
•
T1 system—Recommended by ANSI and widely used in North America and Japan. (Japan
uses the J1 system. This system is considered to be a T1 system because of their similarity.)
A CE1 interface can operate in channelized or unchannelized mode. Support for the channelized and
unchannelized modes depends on the card type.
Channelized mode is also called CE1 mode. In CE1 mode, a CE1 interface is physically divided into
32 timeslots numbered 0 to 31. Timeslot 0 is used to transmit synchronizing information.
In CE1 mode, you can bundle all timeslots except timeslot 0 into a maximum of 31 channel sets.
For each channel set, the system automatically creates a serial interface named serial
interface-number:set-number. This interface has the same logical features as a standard
synchronous serial interface. The interface supports settings including:
•
Data link protocols, such as PPP, HDLC, or FR.
•
IP addressing.
•
Interface backup settings if the interface is used as a primary or backup interface.
•
NAT and packet filtering.
Unchannelized mode is also called E1 mode.
For a CE1 interface in E1 mode, the system automatically creates a 2.048 Mbps serial interface
named serial interface-number:0. This interface has the same logical features as a standard
synchronous serial interface. The interface supports settings including:
•
Data link protocols, such as PPP, HDLC, or FR.
•
IP addressing.
•
Interface backup settings if the interface is used as a primary or backup interface.
•
NAT and packet filtering.
