Network Ports
Description:Three 10/100 Mbps Ethernet ports (LAN1, LAN2, LAN3).
Connector:Three standard RJ-45 8-pin connectors
Frame Format for LAN1, LAN2, LAN3:
n IEEE 802.3 (10Base-T at 10 Mbps)
n IEEE 802.3u (Fast Ethernet at 100 Mbps)
Roles:
n LAN1:
n Web interface (HTTP), command line interface (TELNET)
n The default port for most NTP functions.
n DNS, SMTP, SNMP
n All ports respond to NTP (port 123), TIME (port 37), and DAYTIME (port 13) requests.
