Dell EMC S5248: Fanout and fanin required for all interface #72

Closed waliulislam closed 5 years ago

waliulislam commented 5 years ago

Currently We can fanout 100 gig interface to 1x1 40gig , 4x1 25gig and 4x1 10gig. But after fan out we fail to do Fan in to 1x1 100gig.

dell-pg/port-groups-state/port-group-state/id = port-group-15
dell-pg/port-groups/port-group/id = port-group-15

Port already configured as breakout mode 4 and speed 7

Also we need to fanout 25gig interface to 1x1 10g, to support 10gig transceiver.

root@OPX:~# opx-config-fanout e101-017-0 1x1 10g
Invalid break mode and port speed combination

mode = 4 = 1x1 speed = 7 = 100g fanin failed because each interface belongs to a port-group on s52xx platforms, and temporary workaround of doing fannout on a particular interface did not change the port group breakout mode and speed. So, we need to a develop a utility to fanout the port-group instead of an individual interface and change the port-group configuration accordingly.

3.1.0-rc0 provide a new opx-config-fanout to address the issue
