LACP connection topology in this diagram

[13jobsp90]

Refer the diagram here. I have 2 questions here;

1) Can I stack MS 225 & MS 210 here?

2) If stacking can be done, if i want to give fiber uplinks to m225 & M210 from 9300 model core switch? Will the portchannel works here in fiber sfp ports due to speed difference because MS 225 & 9300 supports 10g & MS 210 supports only 1g sfp.?

      - No , that won't work,

Unfamiliar with MS devices stacking capabilities, so cannot answer #1.

For #2, to my knowledge, Cisco doesn't support mixed port speed Etherchannel.  However, if 10g ports are dual gig/10g SFP+, you could use them with gig transceivers, which should allow them to be Etherchannelled with other gig ports.
