VLAN support:
Port-based and protocol-based VLANs
Up to 4094 VLANs supported per switch (2048 active VLANs), with VLAN numbers 1 - 4094
802.1Q VLAN tagging support on all ports
Ingress VLAN tagging support to tunnel packets through a public domain without altering the
original 802.1Q tagging information
802.1x with dynamic guest VLAN assignment
Private VLANs support as defined in RFC 5517
OpenFlow 1.0 and 1.3.1 support
Virtualization:
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 inter-switch link between the vLAG
peers
Two-tier vLAGs with VRRP enables active/active VRRP support to reduce routing
latency
Supports 802.1Qbg Edge Virtual Bridging (EVB) which 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 providing 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 support:
Up to 1,024 virtual entities (VEs)
Automatic VE discovery
Up to 1,024 local or distributed VM groups for VEs
NMotion® feature for automatic network configuration migration
Stacking: Up to eight switches in a stack; single IP management
Security:
VLAN-, MAC-, and IP-based access control lists (ACLs)
802.1x port-based authentication
Multiple user IDs and passwords
User access control
Radius, TACACS+ and LDAP/LDAPS authentication and authorization
NIST 800-131A Encryption
Selectable encryption protocol
Secure Input/Output Module (SIOM) policy: Secure and Legacy modes
Quality of Service (QoS):
Support for IEEE 802.1p, IP ToS/DSCP, and ACL-based (MAC/IP source and destination
addresses, VLANs) traffic classification and processing
Traffic shaping and re-marking based on defined policies
Eight priority queues per port for processing qualified traffic
Weighted random early detection with explicit congestion notification (WRED/ECN)
Control plane protection (CoPP)
IPv4/IPv6 ACL metering
