Configuring Interface-Based FRF.12 Fragmentation

To configure interface-based FRF.12 Fragmentation, enter the following commands beginning in global
configuration mode:
Command
Step 1
Router(config)# interface serial
slot/module/port.T1#:channel
Step 2
Router(config-if)# hold-queue length {in |
out}
Step 3
Router(config-if)# no ip address
Step 4
Router(config-if)# no ip directed
broadcast
Step 5
Router(config-if)# encapsulation
frame-relay [ietf | cisco]
OL-7433-09
Purpose
Creates or modifies a serial interface. Enters interface
configuration mode.
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.
(Optional) Removes any existing IP address from the main
interface.
(Optional) Disables IP directed broadcasts. Instead, these
broadcasts are dropped.
Specifies Frame Relay as the interface encapsulation type.
(Optional) ietf sets the encapsulation method to comply with the
Internet Engineering Task Force (IETF) standard (RFC 1490).
Use this keyword when connecting to another vendor's equipment
across a Frame Relay network.
(Optional) cisco indicates to use Cisco's own encapsulation,
which is a 4-byte header, with 2 bytes to identify the data-link
connection identifier (DLCI) and 2 bytes to identify the packet
type. This is the default encapsulation type.
