Please check, we can not configure the device or enter conf private mode due to stuck invalid conf after rename physical interface to ae which add speed 1G command to ae5.

configure private

Users currently editing the configuration:

As per RSI, I can see ae5 is already present in config with "speed 1g". Did the config get committed.

  ae5 {

    description "05-3-19-58 BE1 GIG";

    flexible-vlan-tagging;

    speed 1g;

For ae interfaces, the speed is to be configured under aggregated-ether-options

set interfaces ae5 aggregated-ether-options link-speed

Adding speed under ae is incorrect.

root@Router# set interfaces ae5 speed

syntax error.
