Table A-1. COM Interface ifconfig Command Settings
Setting Description
Default Setting
-d Resets the router 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 connection to the network:
1. Nortel Networks HDLC encapsulation (also referred to as
Nortel Networks Standard Point-to-Point) with external clocking
2. Frame Relay Annex D
3. Frame Relay LMI
4. Frame Relay Annex A
56/64K CSU/DSU Settings
-r Configures 56/64K telco service for 56K DDS or 64K Clear Channel.
Use one of the following options: 56 or 64.
Frame Relay Settings
-fr Configures the router COM interface 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 serial interface 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
com<
port #>.
IP Address Settings
<IP_address> Specifies the IP address of the interface you set with <interface>.
Provide this address in dotted decimal notation.
