interface hdlc <label>
Use the interface hdlc command to create a virtual high level data link control interface that is identified
using the entered number label. In addition, entering this command activates the HDLC interface. Use the
no form of this command to delete a configured virtual HDLC interface.
Syntax Description
<label> Specifies the numerical virtual HDLC interface identifying label (valid range:
1 to 1024)
Default Values
By default, there are no configured HDLC interfaces.
Command Modes
(config)# Global Configuration Mode required
Functional Notes
Creating an endpoint that uses a layer 2 protocol (such as HDLC) is generally a four-step process:
Step 1:
Create the HDLC virtual endpoint (using the interface hdlc) command and enter the HDLC configuration
commands.
(config)#interface hdlc 7
(config-hdlc 7)#
Step 2:
Configure the interface parameters to apply access policies to the interface, create bridging interfaces,
configure backup, and assign an IP address. For example, the following assigns an IP address of
193.44.69.1/30 to the interface.
(config-hdlc 7)#ip address 193.44.69.1 255.255.255.252
Step 3: (VALID ONLY FOR T1 INTERFACES)
Specify the group of DS0s used for signaling on the T1 interface by creating a tdm-group. Group any
number of aggregate DS0s together to create a data pipe for layer 2 signaling. Also use the tdm-group
command to specify the per-DS0 signaling rate on the interface. For example, the following creates a
tdm-group labeled 9 containing 20 DS0s (each DS0 having a data rate of 56 kbps).
(config)#interface t1 1/1
(config-t1 1/1)#tdm-group 9 timeslots 1-20 speed 56
(config-t1 1/1)#exit
