# Configuring the SRC Client

You can configure SRC clients on a per-virtual-router basis. To configure the SRC client:

1. Enable the SRC client. With the CLI sscc enable command you can specify BER-encoded information exchange for COPS-PR.
   host1(config)#sscc enable cops-pr
2. Specify the IP addresses of up to three service activation engines (SAEs) (primary, secondary, and tertiary). You can optionally specify the port on which the SAEs listen for activity.
   host1(config)#sscc primary address host1(config)#sscc secondary address 192.168.12.1 port 3288
3. (Optional) Enable policy and QoS configuration support for IPv6 interfaces.
   host1(config)#sscc protocol ipv6
4. (Optional) Enable policy and QoS configuration support for L2TP interfaces on an L2TP access concentrator (LAC).
   host1(config)#sscc protocol lac
5. (Optional) Specify on which router the TCP/COPS connection is to be established.
   host1(config)#sscc transportRouter chicago
6. (Optional) Specify a fixed source address for the TCP/COPS connection created for an SRC client session.
   host1(config)#sscc sourceAddress 10.9.123.8
7. (Optional) Specify a fixed source interface for the TCP/COPS connection.
   host1(config)#sscc sourceInterface atm 3/0
8. (Optional) Specify the delay period during which the SRC client waits for a response from the SAE.
   host1(config)#sscc retryTimer 120
9. (Optional) Enable the user IP address mask to be sent to a Policy Decision Point (PDP) in place of the interface IP address mask for a virtual router.
   host1(config)#sscc option user-ip-mask-override
10. (Optional) Enable the calling station ID to be sent to a PDP for a virtual router.
    host1(config)#sscc option send-calling-station-id
11. (Optional) Enable the local QoS profile attachment information to be sent to a PDP for a virtual router.
    host1(config)#sscc option send-local-qos-profile-config
12. (Optional) Enable the LAC side NAS-IP address information to be sent to a PDP for a virtual router.
    host1(config)#sscc option send-lac-nas-ip
13. (Optional) Enable the LAC side NAS-Port information to be sent to a PDP for a virtual router.
    host1(config)#sscc option send-lac-nas-port
14. (Optional) Enable the SRC client to obtain updated line rate parameters from ANCP and transmit them to the COPS server.
    host1(config)#sscc update-policy-request enable
15. (Optional) Restart a COPS connection to, and resynchronize with, a PDP.
    host1#sscc restart
