Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line
Configuration Sequence
Step 3 Enable Transmission Control Protocol (TCP) header compression.
Router(config-if)# ip tcp header-compression keyword
For example, the following command enables IETF-Format as the header compression:
Router(config-if)# ip tcp header-compression ietf-format
Step 4 Change the length of time for which data is used, enter the following command:
Router(config-if)# load-interval seconds
Where seconds is the length of time for which data is used to compute load statistics. A value that is a
multiple of 30, from 30 to 600 (30, 60, 90, 120, and so forth).
For example, the following command has the length of time set at 30 seconds:
Router(config-if)# load-interval 30
Step 5 Disable the keepalive parameters.
Router(config-if)# no keepalive
Step 6 Disable the Cisco Discovery Protocol (CDP) on the interface.
Router(config-if)# no cdp enable
Step 7 To configure PFC on the router, enter the following command:
Router(config-if)# ppp pfc local {request | forbid}
Where:
• request—The PFC option is included in outbound configuration requests.
• forbid—The PFC option is not sent in outbound configuration requests, and requests from a remote
peer to add the PFC option are not accepted.
For example, the following command creates how the router handles PFC:
Router(config-if)# ppp pfc local request
Step 8 To configure how the router handles the PFC option in configuration requests received from a remote
peer, enter the following command:
Router(config-if)# ppp pfc remote {apply | reject | ignore}
Where:
• apply—PFC options are accepted and ACFC may be performed on frames sent to the remote peer.
• reject—PFC options are explicitly ignored.
• ignore—PFC options are accepted, but ACFC is not performed on frames sent to the remote peer.
For example, the following command allows PFC options to be accepted:
Router(config)# ppp pfc remote apply
