ISR 4331 PuTTy

[DavidDavidB7862]

Hi,

Trying to configuring a ISR4331/K9 with PuTTY using COM4 (usb to serial). in elevated mode (#), gets an error "This command is not supported" while trying to write to memory or copy to start up config or even config t. A reload (soft boot) managed to fix the issue (this is how a config file is pushed to the router) but now a reload is not an option since then missing the config.  So ideas? (the device is brand new). IOS Version 16.9.4.

Upgrade the firmware.

Could u be more specific. it got IOS XE 16.9.4. Upgrade to what version then? roll back?

Wait ... Can you show us what command you're trying to do and what is the error message that follows?

[DavidDavidB7862]

Pretty much any command like: config t, write mem, copy ..., the error is like: This command is not supported. Pls see attached snapshot.

Post the complete output to the command "sh alias".

[DavidDavidB7862]

Only default, complete form of configure terminal command gives same result
Router#sh alias
Exec mode aliases:
h help
lo logout
p ping
r resume
s show
u undebug
un undebug
w where

ATM virtual circuit configuration mode aliases:
vbr vbr-nrt

Router#configure terminal
This command is not supported

16.9.4 is a SDWAN Software release.  With the SDWAN Release, the config is sent via server and not configured locally.  You'll need to change the release to an IOS-XE release and not the SDWAN release.

Thanks Kevin. GREAT help, explains why. Not much information from Cisco about this. And now about downloading a correct version, what is the recommended version to be downloaded, I found this:
https://www.cisco.com/c/en/us/support/ios-nx-os-software/ios-xe-16/tsd-products-support-series-home.html

But there is no 16.9.4 release !! Latest is 16.9.1 !

We are running 16.6.6 for our 4300 fleet.  16.6.6 and 16.9.3 are both recommended by Cisco.  I'd say look at the Open caveats on both and see which one best fits your environment.  If both fit, I'd go with 16.9.3.
