Configuring the SAE to Manage JunosE Routers (SRC CLI)

To set up the SAE to manage JunosE routers, configure a router driver that specifies a COPS server that can accept COPS connections from the COPS client in JunosE routers.

Use the following configuration statements to configure the SAE to manage JunosE routers:

To configure the SAE to manage JunosE routers:

1. From configuration mode, access the configuration statement that configures the JunosE router driver. In this sample procedure, the JunosE driver is configured in the west-region group.
   user@host# edit shared sae group west-region configuration driver junose
2. (Optional) Disable the accounting-per-attachment feature to calculate accounting statistics for each policy list on the basis of the accounting flag status of each policy rule in the policy list.
   [edit shared sae group west-region configuration driver junose]user@host# set no-accounting-per-attachment

   Note: To enable the accounting-per-attachment feature, configure the accounting-per-attachment option at the [edit shared sae group group-name configuration driver junose] hierarchy. By default, the accounting-per-attachment feature is not set. You must restart the sscc connection for the configuration changes to take effect. You can configure the accounting-per-attachment feature under the [edit shared sae group group-name configuration driver junose] or [edit shared network device] hierarchy. The settings configured under the [edit shared network device] hierarchy override the settings under the [edit shared sae group group-name configuration driver junose] hierarchy.

3. Configure the port number of the SAE COPS server. The port number must match the configuration of the SRC client in the JunosE router.
   [edit shared sae group west-region configuration driver junose] user@host# set cops-server-port cops-server-port
4. Configure the number of outstanding connection attempts before connections are dropped.
   [edit shared sae group west-region configuration driver junose] user@host# set backlog backlog
5. Configure the delay time (in milliseconds) for dual-stack interfaces. dual-stack-delay is not configured by default.
   [edit shared sae group west-region configuration driver junose] user@host# dual-stack-delay delay
6. Configure the interval between keepalive messages sent from the COPS client (the JunosE router).
   [edit shared sae group west-region configuration driver junose] user@host# set keepalive-interval keepalive-interval
7. Configure the timeout interval in which the COPS server waits for a response to COPS requests.
   [edit shared sae group west-region configuration driver junose] user@host# set message-timeout message-timeout
8. Configure the maximum length of a COPS message.
   [edit shared sae group west-region configuration driver junose] user@host# set cops-message-maximum-length cops-message-maximum-length
9. Configure the buffer size for receiving COPS messages from the JunosE client. We recommend that you use the default setting unless you are instructed to change it by Juniper Networks.
   [edit shared sae group west-region configuration driver junose] user@host# set cops-message-read-buffer-size cops-message-read-buffer-size
10. Configure the buffer size for sending COPS messages to the JunosE client. We recommend that you use the default setting unless you are instructed to change it by Juniper Networks.
    [edit shared sae group west-region configuration driver junose] user@host# set cops-message-write-buffer-size cops-message-read-buffer-size
11. Configure the maximum time that a DHCP address request remains pending.
    [edit shared sae group west-region configuration driver junose] user@host# set pending-address-timeout pending-address-timeout
12. Configure the size of the thread pool for handling unsolicited messages. These threads are shared among all JunosE router drivers.
    [edit shared sae group west-region configuration driver junose] user@host# set cops-handler-threads cops-handler-threads
13. Configure the minimum amount of time to keep the state of a router driver after its COPS connection has been closed.
    [edit shared sae group west-region configuration driver junose] user@host# set cached-driver-expiration cached-driver-expiration
14. (Optional) If you are using COPS-XDR, specify whether or not the JunosE router driver keeps a record of unmanaged interfaces.
    [edit shared sae group west-region configuration driver junose] user@host# set drop-unmanaged-interfaces-xdr-driver
15. (Optional) Enable or disable sending of interface-tracking events for unmanaged interfaces for the XDR router driver.
    [edit shared sae group west-region configuration driver junose] user@host# set track-unmanaged-interfaces-xdr-driver
16. (Optional) Verify your configuration.
