Configuring a Shaping Policy for MLP Over Frame Relay-Based LFI
MLP over Frame Relay-based LFI required that you configure a QoS policy that shapes traffic.
To configure a QoS policy that shapes traffic for MLP over Frame Relay-based LFI, enter the following
commands beginning in global configuration mode:
Adding a Serial Member Link to a MLP Bundle
You can configure up to 10 member links per MLP bundle for MLP over serial-based LFI. You can also
terminate the serial links on multiple line cards in the router chassis if all of the links are the same type,
such as T1 or E1. The link speeds must be the same for all of the links in the bundle. If the interface you
add to the MLP bundle contains information such as an IP address, routing protocol, or access list, the
router ignores that information. If you remove the interface from the MLP bundle, that information
becomes active again.
To add serial member links to a MLP bundle, enter the following commands beginning in global
configuration mode:
Command
Purpose
Step 1
Router(config)#
policy-map
policy-map-name
Configures the QoS policy. Enters policy-map configuration
mode.
policy-map-name
is the name of the policy map.
Step 2
Router(config-pmap)#
class
class-default
Configures the class-default class. Enters policy-map class
configuration mode.
Step 3
Router(config-pmap-c)#
shape
kbps-value
Shapes traffic to a specified bit rate.
kbps-value
is the bit rate (in kilobits per second) used to shape the
traffic.
Command
Purpose
Step 1
Router(config-if)#
interface serial
slot
/
module
/
port.channel:controller-number
Specifies the interface that you want to add to the MLP
bundle. Enters interface configuration mode.
slot
/
module
/
port
identifies the line card. The slashes are
required.
channel
: is the channel group number. The colon is required.
controller-number
is the member link controller number.
Step 2
Router(config-if)#
hold-queue
length
{
in
|
out
}
Limits the size of the IP output queue on an interface. We
recommend that you configure this command on all physical
interfaces.
length
is a number that specifies the maximum number of
packets in the queue. Valid values are from 0 to 4096. We
recommend 4096 packets for all line cards. By default, the
input queue is 75 packets and the output queue is 40 packets.
in
specifies the input queue.
out
specifies the output queue.
