Medium I am running vpp inside docker. Also using the -s option of vppctl.
Steps to reproduce the issue-
- docker exec into the container
- run vppctl -s localhost:5002
- show interface ( or any other command)
This is intermittent issue. So may have to try the above steps few times. Each time start from the first step. If CLI works on step 3, it will continue to work. If it shows garbled output, it will continue to show garbled output.
here is VPP version when the show command works
vpp# show version
vpp v18.01-rc0~154-gfc1c612 built by root on 903c37e2b8e9 at Fri Nov 3 07:59:47 UTC 2017
the issue is not limited to this version. We have seen the issue in some previous versions as well.
The above was when the CLI worked. Many times it shows garbled output as below.
