We see a lot of IXPs being formed or upgrading with Cisco Nexus 3524 switches, which have 48 1G-10G SFP/SFP+ physical ports, license-limited to 24 active, upgradeable to 48 active.

FWIW, 83% of IXPs have 48 or fewer participants, and 70% of IXPs have 24 or fewer participants.  And the failure rate of chassis-based switches is _way_ higher than that of stand-alone switches.  So we never recommend that an IXP buy a switch larger than necessary to accommodate 18 months reasonably-projectable growth.
