# Configuring the SAE to Manage JUNOSe Routers with the 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:

`

shared sae configuration driver junose {
  cops-server-port cops-server-port ;
  backlog backlog ;
  keepalive-interval keepalive-interval ;
  message-timeout message-timeout ;
  cops-message-maximum-length cops-message-maximum-length ;
  cops-message-read-buffer-size cops-message-read-buffer-size ;
  cops-message-write-buffer-size cops-message-write-buffer-size ;
  pending-address-timeout pending-address-timeout ;
  cops-handler-threads cops-handler-threads ;
  cached-driver-expiration cached-driver-expiration ;
  drop-unmanaged-interfaces-xdr-driver;
  track-unmanaged-interfaces-xdr-driver;
}

`

To configure the SAE to manage JUNOSe routers:

1. From configuration mode, access the configuration statement that configures the JUNOS 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. 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
   `
3. 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
   `
4. 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
   `
5. 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
   `
6. 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
   `
7. 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
   `
8. 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
   `
9. 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
   `
10. 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
    `
11. 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
    `
12. (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
    `
13. (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
    `
14. (Optional) Verify your configuration.

        [edit shared sae group west-region configuration driver junose]
        user@host# show
        cops-server-port 3288;
        backlog 50;
        keepalive-interval 45;
        message-timeout 120000;
        cops-message-maximum-length 200000;
        cops-message-read-buffer-size 30000;
        cops-message-write-buffer-size 30000;
        pending-address-timeout 5000;
        cops-handler-threads 20;
        cached-driver-expiration 600;
        drop-unmanaged-interfaces-xdr-driver;
        track-unmanaged-interfaces-xdr-driver;
