Scheduling

Strict priority and weighted round-robin (WRR)
Queue assignment based on differentiated services code point (DSCP) and class of service (802.1p/CoS)

Class of service

Port based, 802.1p VLAN priority based, IPv4/v6 IP precedence/type of service (ToS)/DSCP based, Differentiated Services (DiffServ)

Rate limiting

Ingress policer, per VLAN and per port

Power over Ethernet

802.3af PoE or 802.3at PoE+ delivered over any of the RJ-45 network ports within the listed power budgets

Switches support 802.3af, 802.3at, and Cisco pre-standard (legacy) PoE with maximum power of 30 W per port.
This applies to the following PoE-enabled models; the maximum number of ports providing PoE power simultaneously is determined by the total PoE budget for the switch listed as below:
PoE Power Budget: 195 W
Number of Ports That Support PoE: 24
