Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line
Configuration Sequence
Step 16 Specify the percent of the interface bandwidth allocated for LLQ.
Router(config-if)# max-reserved-bandwith percent
Where percent is the percent of interface bandwidth allocated for LLQ.
For example, the following command specifies the interface bandwidth allocated for LLQ as 100%:
Router(config-if)# max-reserved-bandwidth 100
Step 17 Assign the QoS boilerplate to the multilink interface.
Router(config-if)# service-policy output policy_name
Where policy_name is LLQ.
For example, the following command assigns the QoS boilerplate to the multilink interface policy name
LLQ:
Router(config-if)# service-policy output llq-policy
Step 18 Set the size of the output queue.
Router(config-if)# hold-queue size in | out
Where:
• size— Number of packets held in the queue.
• in | out—Direction of packets being held, either input or output.
For example, the following command sets the size of the queue for the outbound packets at 50:
Router(config-if)# hold-queue 50 out
Note Specify a hold-queue limit. The limit needs to be greater than the hold-queue depth that is
defined on the default class (see the “Creating a Class Map” section on page 4-47 for more
information).
Step 19 Enable 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
Note In the previous procedure, PVC 2/1 of ATM0/0/0 and ATM0/0/1 will go to the priority queue and PVC
2/2 of ATM0/0/0 and ATM0/0/1 will be considered the best effort traffic and will go to the Weighted Fair
Queue.
