Table 5-2. ifconfig Command Settings for a Synchronous Interface
Setting Description
Default Setting
-d
Resets the router’s IP interface settings to the default values. This
setting tries four WAN configurations in the following order until it finds
the correct type for the router’s connection to the network:
1. Bay Networks HDLC encapsulation (also referred to as
Bay Networks Standard Point-to-Point) with external clocking
2. Frame Relay Annex D
3. Frame Relay LMI
4. Frame Relay Annex A
Frame Relay Settings
-fr
Configures the router’s synchronous port as a Frame Relay
connection. With this setting, use one of the following options to
specify a DLCMI setting: -annexd, -annexa, or -lmi.
-annexd
-annexa
-lmi
When one of these options is used with the -fr setting, it specifies a
DLCMI setting. Use the same setting as the network to which the
router’s Frame Relay interface is connected. The default setting for
Frame Relay is -annexd.
Internal Clocking Setting
-int_clk
Sets the synchronous port to internal clocking at 1.25 MB/s. If you do
not specify this setting, the router defaults to external clocking.
IP Connector Setting
<interface>
Specifies the IP connector you are configuring. Use the format
