Hello Pros,
Today I upgraded my ISR4331 Router to IOS Version: ISR4300-Universal k9.17.06.07.SPA.bin. The upgraded was successful. There was no Serial interface S0/1/0, Which was connected to Secure Circuit before.
I used command: Show Ip int br.
Show interface.
Interface did not shown. I revered back to previous IOS, reload and Interface S0/1/0 appeared/shown as normal.
any idea what I was missing? Is this a common issue/problem? Has Cisco fix this problem. Need your Expert advice.
Thanks in advanced.
Solved! Go to Solution.

Hello @Zee-Far-Man ,
with the old IOS XE version running check
show controller serial 0/1/0
and
show inventory
to understand the hardware module the serial port is part of.
Then in the release notes of the new IOS XE version ISR4300-Universal k9.17.06.07.SPA.bin you need to check for supported HW modules to see if that module is supported or not.
IF it is not supported it is a known issue and you should stay with the old version , if it is listed as supported you are likely hitting a SW bug on the new version.
Hope to help
