Table 13 Features of the OfficeConnect Managed Fast Ethernet PoE Switch (continued)

Feature

Description

 

 

SNMP Alarms and Trap Logs

The system logs events with severity codes and timestamps. Events are

 

sent as SNMP traps to a Trap Recipient List.

 

 

SNMP Versions 1 and 2

Simple Network Management Protocol (SNMP) over the UDP/IP protocol

 

controls access to the system.

 

 

Spanning Tree Protocol

802.1D Spanning tree is a standard Layer 2 switch requirement that

 

allows bridges to automatically prevent and resolve L2 forwarding loops.

 

Switches exchange configuration messages using specifically formatted

 

frames and selectively enable and disable forwarding on ports.

 

 

SSL

Secure Socket Layer (SSL) is an application-level protocol that enables

 

secure transactions of data through privacy, authentication, and data

 

integrity. It relies upon certificates and public and private keys.

 

 

Static MAC Entries

MAC entries can be manually entered in the Bridging Table, as an

 

alternative to learning them from incoming frames. These user-defined

 

entries are not subject to aging, and are preserved across resets and

 

reboots.

 

 

TCP

Transport Control Protocol (TCP). TCP connections are defined between 2

 

ports by an initial synchronization exchange. TCP ports are identified by

 

an IP address and a 16-bit port number. Octets streams are divided into

 

TCP packets, each carrying a sequence number.

 

 

TFTP Trivial File Transfer Protocol

The device supports boot image, software and configuration

 

upload/download via TFTP.

 

 

Virtual Cable Testing

VCT detects and reports copper link cabling occurrences, such as open

 

cables and cable shorts.

 

 

VLAN Support

VLANs are collections of switching ports that comprise a single broadcast

 

domain. Packets are classified as belonging to a VLAN based on either the

 

VLAN tag or based on a combination of the ingress port and packet

 

contents. Packets sharing common attributes can be grouped in the same

 

VLAN.

 

 

Web-based Management

With web-based management, the system can be managed from any

 

web browser. The system contains a Web Server, which serves HTML

 

pages, through which the system can be monitored and configured. The

 

system internally converts web-based input into configuration commands,

 

MIB variable settings and other management-related settings.
