Additional Information:
4 dual-personality ports-each port can be used as either an RJ-45 10/100/1000 port (IEEE 802.3 Type 10Base-T; 802.3u Type 100Base-TX; 802.3ab 1000Base-T Gigabit Ethernet) or an open mini-GBIC slot (for use with mini-GBIC transceivers)Latency:
- 100 MB: <11.8 µs (FIFO 64-byte packets)
- 1000 MB: <4.4 µs (FIFO 64-byte packets)
Dual-personality functionality:
- Four 10/100/1000 ports or mini-GBIC slots for optional fiber connectivity such as Gigabit-SX, -LX, or -LH
Basic IP routing:
- Enables automatic routing with up to 16 external routes-including one default route-in IP networks
IP multicast (data-driven IGMP):
- Automatically prevents flooding of IP multicast traffic
Optional redundant power supply:
- Provides uninterrupted power in case of a power supply failure
RMON and extended RMON:
- Provides advanced monitoring and reporting capabilities for statistics, history, alarms, and events
Port security:
- Prevents unauthorized access using MAC address lockdown
TACACS+:
- Eases switch management security administration by using a password authentication server
Secure Shell (SSHv2):
- Encrypts all transmitted data for secure CLI remote access over IP networks
VLAN:
- Supports up to 60 port-based VLANs, GVRP, and 802.1Q VLAN tagging
Traffic prioritization (802.1p):
- Allows real-time traffic classification into 8 priority levels
Per-port broadcast throttling:
- Selectively configure broadcast control on heavy traffic port uplinks
