Enterprise NOS software features
The RackSwitch G8272 with ENOS has the following 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
Layer 2 Trunk Failover to support active/standby configurations of NIC teaming on servers
Hot Links provides basic link redundancy with fast recovery for network topologies that
require Spanning Tree to be turned off
VLAN support:
Up to 4095 VLANs supported per switch, with VLAN numbers 1 - 4095 (VLAN 4095 is used
by the management network.)
Port-based and protocol-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
Private VLANs support as defined in RFC 5517
Security:
VLAN-based, MAC-based, 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 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) with Explicit Congestion Notification (ECN) to help
avoid congestion
IPv4/IPv6 ACL metering
