Manageability |
• SNMP and Telnet interface support delivers comprehensive in-band management, and a CLI management console provides detailed out-of-band management.
• An embedded RMON software agent supports four RMON groups (history, statistics, alarms, and events) for enhanced traffic management, monitoring, and analysis.
• A SPAN port can mirror traffic from one or many ports to another port for monitoring all eight 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.
• Two LEDs per port provide convenient visual indication of the port link and PoE status.
• Crash information support enables a switch to generate a crash file for improved troubleshooting.
• Show-interface capabilities provide information about the configuration capabilities of any interface. |
|
Connectors and cabling |
• 10BASE-T ports: RJ-45 connectors, two-pair Category 3, 4, or 5 unshielded twisted pair (UTP) cabling
• 100BASE-TX ports: RJ-45 connectors; two-pair Category 5 UTP cabling
• 1000BASE-TX ports: RJ-45 connectors; two-pair Category 5e and Category 6 UTP cabling |
|
LED indicators |
• Link status LED: One LED per port for indicating link status
• PoE LED: One LED per port system for PoE status indication |
