Interface Rate Limit on Juniper EX switches

1. Configure the policer

root@juniperlab# set firewall policer Policer_2M if-exceeding bandwidth-limit 1M
root@juniperlab# set firewall policer Policer_2M if-exceeding burst-size-limit 2k
root@juniperlab# set firewall policer Policer_2M then discard

2. Configure the firewall filter

root@juniperlab# set firewall family ethernet-switching filter Limit term 1 then accept
root@juniperlab# set firewall family ethernet-switching filter Limit term 1 then policer Poicer_2M

3. Apply filter on interface (can be any interface as required)

root@juniperlab# set interface ge-0/0/24.0 family ethernet-switching filter input Limit

Note: Remember that EX series switches apply rate limit only on ingress.

Juniper SRX Routing Instances Configuration and Importing Routes to and from virtual routers

Image
Our goal is to configure routing instances on all devices and provide routing between all instances with ospf protocol. Configure routing instances on SRX1: We will be using a tagged interface ge-0/0/1 where vlan 10 is for vr10.10 routing instance and vlan 20 is for vr20.20: set interfaces ge-0/0/1 vlan-tagging set interfaces ge-0/0/1 unit 10 vlan-id 10 set interfaces ge-0/0/1 unit 10 family inet address 172.16.10.1/24 set interfaces ge-0/0/1 unit 20 vlan-id 20 set interfaces ge-0/0/1 unit 20 family inet address 172.16.20.1/24 Now create routing instances and assign interfaces to them: set routing-instances vr10.10 instance-type virtual-router set routing-instances vr10.10 interface ge-0/0/1.10 set routing-instances vr20.20 instance-type virtual-router set routing-instances vr20.20 interface ge-0/0/1.20 Configure rib-groups to import routes from one routing instance to another (Another alternative is to configure policy-options for importing): set routing-instances vr10.10 routing-opti

Install Junos with USB

You discover that your Junos EX or SRX device does not complete normal boot up. The image seems to be corrupted for some reason, such as a continuous power failure. If this occurs, don’t worry, you can get it back up within few minutes using the USB port. Step 1. Get a USB flash drive. Copy the Junos image to the USB drive (without creating folders). Use FAT file format if the USB size is less than 2 GB. Use FAT32 if the USB size is greater than or equal to 4 GB. The example below uses the file image junos-srxsme-10.4R1.9-domestic .tgz. Step 2. Insert the flash into an EX/SRX USB port. Step 3. Reboot the device. When Junos boots up, you will see the message : Press Space to abort autoboot Do nothing. A little while later, you will see: Hit [Enter] to boot immediately, or space bar for command prompt. Press the space bar. You will be at loader mode; the prompt should be loader>. If the prompt is > , type >boot to make it loader>. Step 4. Now type the following command: lo
