Enabling Hdlc On An Interface; Configuring An Ip Address For An Interface - H3C SR6600 Configuration Manual

The information field can be an arbitrary binary bit set. The minimum length can be
zero and the maximum length is decided by the Frame Check Sequence (FCS) field or
the buffer size of the communicating node. Generally, the maximum length is between
1000 and 2000 bits.
The checksum field can use a 16-bit CRC to check the content of a frame.

Enabling HDLC on an Interface

Follow these steps to enable HDLC on an interface:
To do...
Enter system view
Enter interface view
Enable HDLC on the interface
To check the configuration result, use the display interface command.
To clear the existing statistics on an HDLC interface and start collecting new statistics,
run the reset counters interface command on the interface.

Configuring an IP Address for an Interface

Follow these steps to configure an IP address for an interface:
Enter system view
Enter interface view
Configure an
IP address for
the interface
To configure an HDLC interface to borrow the IP address of another interface, the HDLC
interface (IP unnumbered interface) should be able to learn the network routes of the peer
interface.
When configuring an interface as an IP unnumbered interface, you can use routing
protocols or static routes to learn the peer routes following these guidelines:
system-view
interface interface-type
interface-number
link-protocol hdlc
To do...
Assign an IP address
to the interface
Configure the interface
as an IP unnumbered
interface (Configure
the interface to borrow
the IP address of the
specified interface)
Use the command...
Use the command...
system-view
interface interface-type
interface-number
ip address ip-address { mask |
mask-length } [ sub ]
ip address unnumbered
interface interface-type
interface-number
6-98
Remarks

—
Required
PPP is encapsulated by
default.
Remarks

—
Use either command
By default, no IP
address is assigned
to an interface, and
an interface does
not borrow the IP
address of any other
interface either.
