Return to Step 1 to configure the second port on the VWIC and the ports on any additional VWICs.

Configuring QoS Attributes

To use QoS on the MWR 1941-DC router, you must first create a class map. The class map defines the
criteria that a packet must match to be placed in that class. Once you have created a class map, the router
can recognize packets that are subject to QoS. You must then tell the router the action to take on those
packets by creating a policy map.Once you have completed the creation of a QoS boilerplate, you can
assign it to an interface.
Purpose
Configures the serial interface.
Specify the E1 slot (always 0), port number, and
channel group.
Configures the cable length.
Although you can specify a cable length from
Note
0 to 450 feet, the hardware only recognizes
two ranges: 0 to 49 and 50 to 450. For
example, entering 35 feet uses the 0 to 49
range. If you later change the cable length to
40 feet, there is no change because 40 is
within the 0 to 49 range. However, if you
change the cable length to 50, the 50 to 450
range is used. The actual number you enter is
stored in the configuration file.
Assigns an IP address and subnet mask to the
interface.
If the interface is a member of a Multilink bundle
(MLPPP), then skip this step.
Configures PPP encapsulation.
Before you can enable RTP header compression, you
must have configured a serial line that uses PPP
encapsulation
Enables keepalive packets on the interface and
specify the number of times keepalive packets will be
sent without a response before bringing down the
interface.
When enabled in an IP-RAN solution, the
Note
recommended configuration is keepalive 1 2
on both the MWR 1941-DC serial interface
and associated MGX-RPM-1FE-CP virtual
template interface.
Sets the carrier delay for the serial interface.
Exits to global configuration mode.
