Step 6
Router(config)# frame-relay map-class
map-class-name
Creates or modifies a Frame Relay map class. Enters Frame
Relay map-class configuration mode.
map-class-name is the name of the map class.
Step 7
Router(config-fr-mc)# service-policy {input |
output} policy-map-name
Applies the policy map you specify to the Frame Relay map
class. This is the same policy map that you created in Step 1.
input indicates to apply the QoS policy to inbound packets.
output indicates to apply the QoS policy to outbound
packets.
policy-map-name is the name of the policy map you want to
apply to the Frame Relay map class.
Step 8
Router(config-fr-mc)# exit
Exits Frame Relay map-class configuration mode.
Step 9
Router(config)# interface type
slot/subslot/port.subinterface
Specifies the interface or subinterface on which you want to
enable PVC oversubscription. Enters interface or
subinterface configuration mode.
Step 10
Router(config-subif)# encapsulation frame-relay
[cisco | ietf]
Enables Frame Relay encapsulation on the subinterface.
(Optional) cisco specifies 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.
(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.
Step 11
Router(config-subif)# frame-relay
interface-dlci dlci [ietf | cisco]
Assigns a data-link connection identifier (DLCI) or a PVC
to a Frame Relay interface or subinterface. Enters DLCI
configuration mode.
dlci is the DLCI number to be used on the specified
subinterface. This is the DLCI to which you want to attach
the policy map you created in Step 1.
(Optional) cisco specifies 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.
(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.
Step 12
Router(config-if-dlci)# frame-relay class name
Associates a map class with a DLCI.
name is the name of a previously configured map class. This
is the same map class that you created in Step 6.
Note Repeat Steps 11 and 12 for each DLCI to which you
want to associate the map class.
