IOS to NX-OS Configuration Translator

Paste a Cisco IOS config and get the NX-OS equivalent, or go the other direction. The translator detects required NX-OS feature commands, renames interfaces (GigabitEthernet becomes Ethernet), converts VRF, OSPF, BGP, HSRP, and spanning-tree, and flags anything that needs a human decision.

When you need it: Catalyst to Nexus migrations where hundreds of interface stanzas need renaming, validating that a hand-written NX-OS config matches the old IOS intent, or estimating how much of a config will convert cleanly before you schedule the change window. Every command the translator cannot map safely is listed as a warning for manual review, so you know exactly where the human work is.

What it does

Frequently asked questions

Which directions are supported?

Both. IOS to NX-OS and NX-OS to IOS.

What does it convert?

Interface names, VRF definitions, OSPF network statements, BGP peer-groups, HSRP to VRRP hints, and spanning-tree settings. It also emits the NX-OS feature commands the target platform needs.

Will it flag things I need to check?

Yes. Commands that need a human decision are called out as manual review warnings rather than silently guessed. Treat the output as a reviewed starting point, not a finished config.
