NE80E, Version is V3R3C02B608.
I removed the pos 11/0/1 interface from ip-trunk. But after deleting the configuration of pos interface I was unable to add this interface to ip-trunk. It showed the message "delete the configuration of interface". But there was no configuration on that interface. I used other pos 4/0/0 for this connectivity and pos 4/0/0 was added successfully.
"delete the configuration of interface"
I had tried to remove the "transmission down x " command by the command "undo transmission down x" but "undo transmission down x" was also there. And this configuration caused the pos interface fail to be added to ip-trunk.
At last we removed the
cofiguration "undo transmission down x" with the command "transmission-alarm down lais los lof" which recovered the default configuation of that pos interface.
We compared the configuration under Pos 11/0/1 and 4/0/0.
interface pos 11/0/1
undo transmission-alarm down lais lof los lrdi oof pais prdi sdbere sfbere puneq
interface pos 4/0/0
We need to delete all the configuration under the pos interface except the basic ones such as shutdown, link-protocol and loopback before adding it to ip-trunk.
1. Please R&D improve this issue in the new version because it's the popular operation habit of VRP with undo to delete configuration.
2. Please also correct this issue in the manual of V3R3.
