Cisco Nexus NX-OS tips and tricks
The Cisco Nexus series switches are modular and fixed port network switches designed for the data center. Cisco Systems introduced the Nexus Series of switches on January 28, 2008. The first chassis in the Nexus 7000 family is a 10-slot chassis with two supervisor engine slots and eight I/O module slots at the front, as well as five crossbar switch fabric modules at the rear. Beside the Nexus 7000 there are also other models in the Nexus range.
All switches in the Nexus range run the modular NX-OS firmware/operating system on the fabric. NX-OS has some high-availability features compared to the well-known Cisco IOS. This platform is optimized for high-density 10 Gigabit Ethernet.
I'll be sharing with you a little bit about tricks I learned:
Hexadecimal / Decimal conversion:
Executing multiple CLI commands in one command:
Configuration Snapshots and rollback:
Then, I do a small configuration change on the hostname. Now, you can run a “diff” between the current config and the snapshot, using the command: show diff rollback-patch checkpoint name running-config
At this point, you can restore the checkpoint config with the rollback command: Rollback running-config checkpoint name atomic
Command "where" | "where detail":
We can also be root without problem:
Attach to a module:
" | include ... "
