Junos: SRX Cluster Software Update

Junos: SRX Cluster Software Update

I have had the wonderful joy of performing a SRX software update and it was pretty painless so here is the procedure

  • Run the following command on each of the nodes
    • request system software add no-copy unlink
  • Once the above command has completed on all nodes complete by performing a reboot of the nodes
    • request system reboot
  • Allow the nodes to reboot and you are done!

If you are using the virtual model of the SRX appliance please ensure that you have a snapshot before performing any firmware / software updates

Junos: vSRX Cluster Gremlins

Junos: vSRX Cluster Gremlins

Okay so you can probably tell from the rest of the blog I work with Junos on a regular basis and I have found a bug that has been logged with Juniper that effects there current vSRX releases upto version D60. It would only effect your SRX if you running in chassis cluster mode and what would happen is that it would fail to detect the network interfaces

Anyway Juniper have agreed that it is an issue on there virtual appliance and a work around will be released hopefully the first week of December 2016

 

Junos: Hidden Commands Monitor Interface Traffic

Junos: Hidden Commands Monitor Interface Traffic

Found a useful command today that allows you to capture interface traffic and dum it into a pcap file and you can even view the content of the file within the SRX CLI

To Start Traffic Monitoring

user@srx>monitor traffic interface ge-0/0/1.0 write-file test.pcap

To View Capture File

user@srx>monitor traffic read-file test.pcap
