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.?
