Network Management Features
The switches have the following major network management
features:
# SNMP Management Information Base (MIB) II, SNMP MIB
extensions, Bridging MIB (RFC 1493), and Telnet support
deliver comprehensive in-band management
# Web-based management
# Local Omega, a menu-based management console, provides
detailed out-of-band configuration
# VLAN by port and 802.1Q VLAN tagging
# Embedded MIB statistics for enhanced traffic management,
monitoring, and analysis
# IEEE 802.1d Spanning Tree Protocol support for redundant
backbone connections and loop-free networks simplifies
configuration and improves fault tolerance
MAC Addressing
The switch has hardware base support with Internal Address Lookup
Engine (IALE) for static entries and self-learning of active MAC
addresses. The switch supports 2K MAC addresses in CAM.
Store-and-
Forward Mode
With store-and-forward switching mode, network administrators can
optimize performance and enable full-error checking.
The store-and-forward mode works in the following way. First, as the
packet is being received, it is placed in a buffer and held there until
the entire packet is received. The packet is also being checked for
errors and is not forwarded unless the entire packet is error-free. This
mode is automatic when data is exchanged between 10Base and
100Base ports.
Transmit Pacing
Transmit pacing is enabled on a per port basis. When transmit pacing
is enabled, the switch alters its transmission routine during heavy
network activity. When the switch senses heavy traffic, it alters its
transmission routing by intentionally inserting additional delay
between transmission attempts. This added delay reduces collision
rates, thus reducing the number of transmission attempts, which
helps reduce CPU utilization, lightens overall network traffic, and
allows the network time to normalize before attempting
transmission.
