A very basic Juniper Snmp config. (Readonly)

{master}[edit]
marcel@re0.lab2# show snmp
    location Amsterdam;
    contact "netops@domain.tld";
    community blablablabla {
    authorization read-only;
    clients {
        10.10.10.1/32;
        172.16.1.200/32;
    }
}
Very basic and easy I’m not a personal helpdesk so figure out your self how to configure read-write

To upgrade Junos on a M-series Juniper with redundant routing engines you do it the following way.

1.  Log in to the master Routing Engine.

2.  Enter the JUNOS software configuration mode:

	{master}

	marcel@re0.lab2> configure

3.  Disable Routing Engine redundancy.

	{master} [edit]

	marcel@re0.lab2# delete chassis redundancy

4.  Save the configuration change on both Routing Engines.

	{master} [edit]

	marcel@re0.lab2# commit synchronize and-quit

5.  Log in to the backup Routing Engine.

       {master}
        marcel@re0.lab2> request routing-engine login other routing-engine

	{backup}

	marcel@re1.lab2> request system software add

	/var/home/marcel/jinstall-8.xxx.x-domestic-signed.tgz reboot

6.  Switchover to the other Routing Engine to change the role.

       {backup}
        marcel@re1.lab2> quit

       {master}
       marcel@re0.lab2> request chassis routing-engine master switch
      
       marcel@re0.lab2>

7.  Install the new software version on the Backup Routing Engine.

	{backup}

	marcel@re0.lab2> request system software add

	/var/home/marcel/jinstall-8.xxx.x-domestic-signed.tgz reboot

8.  Enable Routing Engine Redundancy again 

	{master}

	marcel@re1.lab2> configure

	[edit]

	marcel@re1.lab2# rollback 1

9.  Save the configuration change on both Routing Engines

	[edit]	marcel@re1.lab2> commit synchronize and-quit

10.  If you are satisfied that the new software is running smoothly

                     {master}

	marcel@re1.lab2> request routing-engine login other routing-engine

	{backup}

	marcel@re0.lab2> request system snapshot

	{backup}

	marcel@re0.lab2> quit

Something about aggregated links on Juniper M series.

It is not hard to config aggregated links.

[edit]
marcel@lab2# show chassis
aggregated-devices {
    ethernet {
        device-count 2;
    }
}
---
[edit]
marcel@lab2# show interfaces ge-1/0/0
gigether-options {
    802.3ad ae0;
}

[edit]
marcel@lab2# show interfaces ge-1/1/0
gigether-options {
   802.3ad ae0;
}

[edit]
marcel@lab2# show interfaces ae0
description "AE0 towards lab-1";
unit 0 {
   family inet {
       filter {
           input AMSIX-in;
           output AMSIX-out;
       }
       address 10.10.4.2/30;
   }
   family inet6 {
       address 2001:0960:1300:1144::1/64;
   }
}

It is also possible to use load balancing per packet.
