Hello Guys
First of all, let me ask you another question:
- Do you think if a combination of C9500 and C9200 is a reasonable upgrade of a combination of C3850 and C2960X ?( A collapsed core environment )
- When we read C9500 documents and data sheet, Cisco has mentioned it's necessary to use 10G/40G links to implement StackWise . But it didn't mentioned about link speed of dual-active detection? I was thinking, is it possible to use a couple of 1G links (GLC-SX-MMD or even GLC-T) to configure Dual-Active Detection because it's more cost effective.
Note: I've sent an email to Cisco to add the answer to its documents.
