SNMP Management Information Base (MIB) II

SNMP MIB extensions, Bridging MIB (RFC 1493) 

 

Comprehensive Manageability:

Simple Network Management Protocol (SNMP) and Telnet interface support delivers comprehensive in-band management, and the Cisco IOS CLI-based management console provides detailed out-of-band management

CMS, a built-in Hypertext Transfer Protocol (HTTP) server, provides an ease-of-use Web-based management interface through a standard browser such as Netscape Navigator or Microsoft Explorer

The switch is manageable through CiscoWorks Windows and CiscoWorks 2000 network management software on a per-port and per-switch basis, providing a common management interface for Cisco routers, switches, and hubs

Cisco Discovery Protocol (CDP) enables a CiscoWorks network management station to automatically discover the switch in a network topology

An embedded Remote Monitoring (RMON) software agent supports four RMON groups (history, statistics, alarms, and events) for enhanced traffic management, monitoring, and analysis

Cisco IOS software supports all nine RMON groups through use of a Switched Port Analyzer (SPAN) port, which permits high-performance traffic monitoring of a single port, a group of ports, or the entire switch from a single network analyzer or RMON probe

Autoconfiguration eases deployment of switches in the network by automatically configuring multiple switches across a network via a boot server

Trivial File Transfer Protocol (TFTP) reduces the cost of administering software upgrades by enabling downloads from a centralized location

Each port includes a multifunction LED for port status, half-duplex/full-duplex, and 10Base-T/100Base-T indications as well as switch-level status LEDs for system, module status, redundant power supply (RPS), and bandwidth utilization, providing a comprehensive and convenient visual management system

Domain Name Services (DNS) client support provides IP address resolution with user-defined device names

Network Time Protocol (NTP) provides an accurate and consistent timestamp to all switches within the intranet

Spanning Tree Root Guard (STRG) prevents devices not in the network administrator's or service provider's control from becoming STP root nodes

Cisco Virtual Trunking Protocol (VTP) Pruning limits broadcasts on VTP trunks. When VTP pruning is enabled, broadcast traffic is flooded only on trunk links required to reach the destination devices
