1. Enter the RADIUS configuration statement:
set system radius-server 172.26.27.5
2. You can also include a shared secret in the command statement and,
if necessary, the port number:
set system radius-server 172.26.27.5 port 1845
set system radius-server 172.26.27.5 secret Jun1p3r
3. Specify the order in which JUNOS should attempt authentication:
set system authentication-order [ radius tacplus password ]
4.
set system login user adminjlk class super-user
set system login user remote class super-user

CLUSTER
Physically connect the two devices and ensure that they are the same models. For example, on the SRX1500 Services Gateway, connect the
dedicated control ports on node 0 and node 1.
For SRX300, SRX320, SRX340, and SRX345 devices, connect ge-0/0/1 on node 0 to ge-0/0/1 on node 1.
Set the two devices to cluster mode and reboot the devices. You must enter the following operational mode commands on both devices, for example:
On node 0:
content_copy
zoom_out_map
user@host> set chassis cluster cluster-id 1 node 0 reboot
On node 1:
content_copy
zoom_out_map
user@host> set chassis cluster cluster-id 1 node 1 reboot
The cluster-id is the same on both devices, but the node ID must be different because one device is node 0 and the other device is node 1.
The range for the cluster-id is 0 through 255 and setting it to 0 is equivalent to disabling cluster mode.

On any J-series router, back up the filesystem to a device that is connected to the router’s USB port:
aviva@RouterA> request system snapshot media usb
On J4300 and J6300 routers, you can also back up the files in the router’s filesystem to a removable compact flash disk:
aviva@RouterA> request system snapshot media removable-compact-flash
Before installing the software upgrade, delete old log- and crashfiles:
aviva@RouterA> request system storage cleanup
-----------------------------------------------------------------------------------------------------------------
Restoring a Backed-Up Filesystem
You want to restore a filesystem that you backed up by taking a snapshot.
Solution
First, reboot the router from the alternate boot media to which you saved the snapshot. On M-series and T-series routers, this is the hard disk:
aviva@RouterA> request system software reboot media disk
On J-series routers, this is either a removable compact flash card or a device connected to the router’s USB port:
aviva@RouterA> request system software reboot media removable-compact-flash
or
aviva@RouterA> request system software reboot media usb
Then, retake the snapshot to copy the filesystem to the media from which you didn’t boot:
aviva@router1>
request system snapshot
or
aviva@RouterA> request system snapshot media removable-compact-flash
