Should Have Gone With Cisco

I decided to upgrade our two Nexus boxes to the latest code before putting them on the network. The procedure is a bit different compared to a regular IOS upgrade. You need to download two files– the NX-OS image, and the “kickstart” image that corresponds to it. I chose to connect to the management port on the supervisor to upload the image. It’s in its own vrf so don’t forget that when trying to ping, etc.

Here is the process below as I did it ::

switch(config)# inter mgmt 0
switch(config-if)# ip address 1.1.1.2 255.0.0.0
switch(config-if)# no shut
switch(config-if)# end

switch# ping 1.1.1.1 vrf management

switch# copy ftp://1.1.1.1/n7000-s1-dk9.4.1.3.bin bootflash:
Enter vrf (If no input, current vrf ‘default’ is considered): management
Enter username: ftp
Password:
***** Transfer of file Completed Successfully *****

switch# copy ftp://1.1.1.1/n7000-s1-kickstart.4.1.3.bin bootflash:
Enter vrf (If no input, current vrf ‘default’ is considered): management
Enter username: ftp
Password:

switch# install all kickstart bootflash:n7000-s1-kickstart.4.1.3.bin system bootflash:n7000-s1-dk9.4.1.3.bin

Switch will be reloaded for disruptive upgrade.
Do you want to continue with the installation (y/n)? [n] y

At this point, the switch upgrades and reboots. Allow 15-20 minutes for the upgrade. Since I connected a lot of 10 gig uplinks this week, it’s almost time to start working on the configs.
