| Manageability | SNMP and Telnet interface support delivers comprehensive in-band management, and a CLI management console provides detailed out-of-band management. An embedded Remote Monitoring (RMON) software agent supports four RMON groups (history, statistics, alarms, and events) for enhanced traffic management, monitoring, and analysis. A Switched Port Analyzer (SPAN) port can mirror traffic from one or many ports to another port for monitoring all nine RMON groups with an RMON probe or network analyzer. Trivial File Transfer Protocol (TFTP) reduces the cost of administering software upgrades by downloading from a centralized location. Network Timing Protocol (NTP) provides an accurate and consistent time stamp to all switches within theintranet. Two LEDs per port provide convenient visual indication of the port link and inline power status. Crash information support helps enable a switch to generate a crash file for improved troubleshooting. Show-interface capabilities provide information about the configuration capabilities of any interface. The Response Time Monitoring (RTTMON) MIB allows users to monitor network performance between the HWIC switch and a remote device. |
