Software features
Note: The features and specifications that are listed in this section are based on Networking OS 8.4.
The G8052 switch has the following software features:
Scalability and performance:
Media access control (MAC) address learning with automatic updates
Static and LACP (IEEE 802.3ad) link aggregation
Broadcast/multicast storm control
IGMP snooping for 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 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 network adapter teaming
on servers
Hot Links provides basic link redundancy with fast recovery for network topologies that
require Spanning Tree to be turned off
