Hello,
I am trying to attach a Mellanox Breakout Cable to one of my Ethernet Ports but its providing the following Error "Failed to break out Port. Error: Failed to load the config. Error: ConfigMgmtDPB Class creation failed"
I have a QSFP28 Breakout Cable that i would like to do 4x25Gb Ports on my SN2700, from what i notice i cannot even set the breakout command to 4x25 it makes me do 4x10 but it fails
admin@sonic:~$ sudo config interface breakout Ethernet8
1x100G[50G,40G,25G,10G] 2x50G[25G,10G] 4x10G[25G]

Hi,
Here's a new user's question: How to reset the switch's SONIC configuration to factory default? It has gone through some config changes.
Can someone provide a link to SONIC user manual (CLI Reference)? Does such a document exist?
Thanks.
Eric
