Intranet VPN Business Scenario 3-11

Verifying Weighted Fair Queuing

To verify the conﬁguration:

• Enter the show interfaces serial 1/0 fair-queue EXEC command to see information on

the interface that is conﬁgured for WFQ.

hq-sanjose# show interfaces serial 1/0 fair-queue

Serial1/0 queue size 0

packets output 35, drops 0

WFQ: global queue limit 401, local queue limit 200

• Enter the show interfaces serial 1/0 EXEC command to verify the queuing for the

interface is WFQ.

hq-sanjose# show interfaces serial 1/0

Serial1/0 is up, line protocol is up

Hardware is M2T-T3 pa

Step 3—Conﬁguring Encryption

The most important part of building a VPN is maintaining security, while allowing

authorized users access. The Integrated Service Module (ISM) in slot 5 of Cisco 7100

series routers provides hardware-based data encryption services for Cisco 7100 series

routers. The hardware-based service provided by the ISM improves the overall

performance of Cisco 7100 series routers by off-loading data encryption processing from

the main system processor. The ISM supports IP Security Protocol (IPSec), Internet Key

Exchange (IKE), and Certiﬁcation Authority (CA) interoperability features.
