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
