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
