Quality of Service (QoS):
Support for IEEE 802.1p, IP ToS/DSCP, and ACL-based (MAC and IP source and destination
addresses, VLANs) traffic classification and processing
Traffic shaping and re-marking that is based on defined policies
Eight Weighted Round Robin (WRR) priority queues per port for processing qualified traffic
IPv4/IPv6 ACL metering
IP v4 Layer 3 functions:
Host management
IP forwarding
IP filtering with ACLs; up to 256 ACLs supported
Virtual Router Redundancy Protocol (VRRP) for Layer 3 router redundancy
Support for up to 128 static routes
Routing protocol support (RIP v1, RIP v2, OSPF v2, and BGP-4); up to 2,048 dynamic routes
Support for DHCP Relay
Support for IGMP snooping and IGMP relay
Support for Protocol Independent Multicast (PIM) in Sparse Mode (PIM-SM) and Dense
Mode (PIM-DM)
IP v6 Layer 3 functions:
IPv6 host management (except default switch management IP address)
IPv6 forwarding
Up to 128 static routes
Support for OSPF v3 routing protocol
IPv6 filtering with ACLs; up 128 ACLs supported
Virtualization:
Virtual NIC (vNIC): Ethernet, iSCSI, or FCoE traffic on vNICs (adapter-specific)
Unified fabric port (UFP):
Up to eight UFP virtual ports (vPorts) per 10 GbE physical port (adapter-specific)
Ethernet, iSCSI, or FCoE traffic on vPorts
Up to 1,024 VLAN for the virtual ports
Integration with L2 failover
Virtual link aggregation groups (vLAGs)
Two switches (vLAG peers) act as a single virtual entity for a multi-port aggregation
vLAG Peer Gateway for improved usage of the link between the vLAG peers
Two-tier vLAGs with VRRP enables active/active VRRP to reduce routing latency
802.1Qbg Edge Virtual Bridging (EVB) is an emerging IEEE standard for allowing networks to
become virtual machine (VM)-aware:
Virtual Ethernet Bridging (VEB) and Virtual Ethernet Port Aggregator (VEPA) are
mechanisms for switching between VMs on the same hypervisor.
Edge Control Protocol (ECP) is a transport protocol that operates between two peers
over an IEEE 802 LAN, which provides reliable, in-order delivery of upper layer
protocol data units.
Virtual Station Interface (VSI) Discovery and Configuration Protocol (VDP) allows
centralized configuration of network policies that persist with the VM, independent of
its location.
EVB Type-Length-Value (TLV) is used to discover and configure VEPA, ECP, and VDP.
VMready:
Up to 4,096 virtual entities (VEs)
Automatic VE discovery
Up to 4,096 local or distributed VM groups for VEs
NMotion® feature for automatic network configuration migration
