We already configure our QEMU in GNS3 and run our vSRX Router. Now its time to configure DHCP server in our vSRX router. Lets began. Logical Diagram for this tutorial To configure DHCP server Assign Lowest and highest IP range root# set system services dhcp pool 192.168.1.0/24 address-range low 192.168.1.50 high 192.168.1.200 Assign DNS server (in my case I had used Router interface IP) root# set system services dhcp pool 192.168.1.0/24 name-server 192.168.1.1 Assign IP address of the router root# set system services dhcp pool 192.168.1.0/24 router 192.168.1.1 Assign the lease time root# set system services dhcp pool 192.168.1.0/24 default-lease-time 3600 Assign DHCP as an allowed inbound service for the interface which we are going to enable DHCP. root# set security zones security-zone untrust interfaces ge-0/0/1 host-inbound-traffic system-services dhcp Assign IP address to the client faced interface. root# set interfaces ge-0/0/1 unit 0 family inet ad

In this tutorial I'm going to run vSRX JunOS in QEMU and configure it as DHCP Server. Lets began with installing vSRX into QEMU. I have try vSRX to run into Vbox but never succeeded. So I better to choose QEMU otherwise waste of time. In my case I had used junos-vsrx-12.1X46-D10.2-domestic to mount into QEMU. Search for it. Now we have to convert our .vdi file into .image, for that use following command cd d:\junos\ c:\Program Files\GNS3\qemu\>qemu-img.exe convert -O qcow2 d:\junos\junos-vsrx-12.1X46-D10.2-domestic-disk1.vdi d:\junos\junos-vsrx-12.1X46-D10.2-domestic.img We just made our image ready to run into QEMU. Go the GNS3 Note: Strongly recommended to use QEMU in linux and enable KVM otherwise it eats up all your CPU and RAM. -nographic -smp 2 -enable-kvm >edit>preference>choose "QEMU VMs" Click on "New" Choose "Default " Gave Name "vSRX" (in my case). I'll use following topology

While doing some lab test, this weird syslogd message appear every seconds on the console terminal, so it was very difficult to complete the lab. This messages are due the following syslog configuration .  So for now we are going to de-activate it to generating the message #deactivate system syslog user *  #commit

Here are some useful command in day to day life while troubleshooting the juniper switch.  1. show mac add of specific vlan   root@jpudasaini#show ethernet-switching table vlan 608 2. compare configure before commit    root@jpudasaini #show | compare 3. check mac add    root@jpudasaini #show ethernet-switching table brief 4. show perticular Mac in Juniper    root@jpudasaini #show ethernet-switching table | match d4ca.6dea.d420 5. show port description/status    root@jpudasaini #show interfaces descriptions statistics 6. Show configuration in configuration mode    root@jpudasaini #show configuration | display set 7. show correctness of the command before commit    root@jpudasaini #commit check 8. Show Link Layer detection Protocol     root@jpudasaini # show protocols lldp  9. Show vlan in configuration mode root@jpudasaini#show vlans | display set

Hello fellow blog reader, after long gap I'm going to write this thread regarding the basic Juniper command and configuration. I try to include as much as troubleshooting/configuration command during day to day work. I would like to thank to Srijan pointing the error on LACP command. 1. Set username for login root@jpudasaini#set system root-authentication encrypted-password New password: Retype new password: root@jpudasaini#set system login user jay full-name jaypudasaini uid 400 class super-user authentication encrypted-password 2. Hostname configuration. root@switch#set system host-name jpudasaini root@jpudasaini# 3. Set Tacplus authentication for juniper switch. root@jpudasaini# set system authentication-order tacplus root@jpudasaini# set system authentication-order password root@jpudasaini# set system root-authentication encrypted-password "you password here" root@jpudasaini# set system tacplus-server 10.10.10.10(your tacplus server IP) secret &quo

Recently I encounter weird issue with JunOS. While Cold Booting the Juniper ex4200 switch its shows following message. I do nothing just first boot the device thus face unknown reason message. Then I dig the google however some command doesn't work except below one. This JunOS version was 12.3. sw1@jpudasaini>show system storage partition Solution EX root>request system reboot slice alternate media internal   SRX root>request system reboot media internal   Now reboot your device and the error message is already gone. To verify the which boot partition do used by your device use the following command.

In my previous blog post you know how to make JunOS vdi to install into Virtuabox. Some of you may try to run it fromVBox main window. When ever you try to run JunOS from VBox window you may encounter below error message and nothing happen. BTX loader 1.00 BTX loader is 1.02 Don't run it form the VirtuaBox main windows. Please go to my previous blog post .

 This is the Step 2 in our GNS3 Lab with JunOS, Quagga and Cisco router. I have tried different tutorial posted in other blogs. I've never found any tutorial  work until now. Every-time I stuck at the middle of the tutorials.  In this blog post, I'll show you how to install JunOS in VBox and later I'll integrate it into GNS3 lab. I have take Olive12.1R1.9.img, I know you're smart to get it from the Internet. Lets begin the installation of JunOS. Before that, convert the JunOS image into Vbox vdi Image. For easy installation and to avoid error during this tutorial, enter into the JunOS folder, in my case. This tutorials assume that you have already install GNS3 and VBox . Step 1 Prepare JunOS for VBox. C:\Users\jpudasaini\Desktop\jun>"C:\Program Files\Oracle\VirtualBox\VBoxmanage" convertdd Olive12.1R1.9.img Olive12.1.R1.9.vdi Its take time to convert the image, wait for few minute depends on your PC configuration. Now go to the jun fol
