encapsulation dot1q vlan-identifier
Choose the item 11 of prompt, it will display:
(00)dot1Q
Please Input the code of command to be excute(0-0): 0
Input 0 and the value of vlan-identifier，then the encapsulation of protocol for the sub-interface is
complete.
3. Configuring Serial Interface
For hardware technical descriptions and information about installing interfaces, refer to the hardware
installation and configuration publication for your product. For a complete description of serial interface
commands used in this chapter, refer to the "Interface Command" chapter. To locate documentation of
other commands that appear in this chapter, use the command reference master index or search online,
which is include following content:
3.7.5 Configuring Synchronous Serial Interface
The configuration of synchronous serial interface consists of following steps. The first step is
prerequisite and others are optional.
Please see the "Example of interface configuring" in the last place to find the example of configuration
task.
1. Specify Synchronous Serial Interface
In the global configuring mode, each following commands is use for assign the synchronous serial
interface and enter the status of interface configuring (if asynchronous card be chose, e.g. 16
asynchronous card provides only asynchronous communication, use async to replace serial):
Command
interface serial slot/port
interface
slot/port:set-channel-group
Input the command "interface" and it will list all the parameters：
(00)FastEthernet
(01)Ethernet
(02)Serial
......
Please Input the code of command to be excute(0-10): 2
Input 2, choose the item "serial", it will prompt:
Please input a interface name:
Input the serial, slot and port names, enter the interface configuration.
Input the name of the serial, slot, port and channel-group, enter the configuration of channelized E1
interface.
2. Specify Synchronous Serial Interface Encapsulation
By default, synchronous serial lines use the High-Level Data Link Control (HDLC) serial encapsulation
method, which provides the synchronous framing and error detection functions of HDLC. The
synchronous serial interfaces support the following serial encapsulation methods:
♦ High-level Data Link Control (HDLC)
Command
IEEE 802.1Q Virtual LAN
