Software features
The NE1032 RackSwitch with Cloud NOS has the following software features and specifications:
Scalability and performance:
Media access control (MAC) address learning with automatic updates
Static and LACP (IEEE 802.3ad) link aggregation
Broadcast and multicast storm control
IGMP snooping to limit flooding of IP multicast traffic
IGMP filtering to control multicast traffic for hosts participating in multicast groups
Configurable traffic distribution schemes over trunk links based on source or destination IP or
MAC addresses, or both
Fast port forwarding and fast uplink convergence for rapid STP convergence
Availability and redundancy:
IEEE 802.1D STP for providing L2 redundancy
IEEE 802.1s Multiple STP (MSTP) for topology optimization
IEEE 802.1w Rapid STP (RSTP) provides rapid STP convergence for critical delay-sensitive
traffic, such as voice or video
Per-VLAN Rapid STP (PVRST) enhancements
VLAN support:
Up to 4095 VLANs:
VLAN 1 is the default VLAN
VLAN numbers 2 - 3999 are user-configurable
VLAN numbers 4000 - 4095 are reserved for the use by the switch
Port-based VLANs
802.1Q VLAN tagging support
Ingress VLAN tagging support to tunnel packets through a public domain without altering the
original 802.1Q tagging information
Security:
VLAN-based, MAC-based, and IP-based access control lists (ACLs)
Multiple user IDs and passwords
User access control
Radius and TACACS+ authentication and authorization
Quality of Service (QoS):
Support for IEEE 802.1p, IP ToS/DSCP, and ACL-based (MAC/IP source and destination
addresses and VLANs) traffic classification and processing
Traffic shaping and re-marking that is based on defined policies
Eight output Class of Service (COS) queues per port for processing qualified traffic
Weighted Random Early Detection (WRED) to avoid congestion
Control Plane Protection (CoPP)
IPv4 ACL metering
IP v4 Layer 3 functions:
Host management
IP forwarding
IP filtering with ACLs
Virtual Router Redundancy Protocol (VRRP) for router redundancy
Static routes
Routing protocols (OSPF v2 and BGP)
Policy-based routing (PBR)
DHCP Relay and DHCP Snooping
IGMP snooping
DNS client
