Fast Ethernet Ports
Ethernet LANs (Ethernet segments) are physically connected to the 7600
Card through one of its 16 Fast Ethernet ports. Each port has a unique
address and port number. Figure 11-2 below shows Ethernet LANs
connected to the 7600 Card Ethernet ports.

Disabling Ports
Individual Ethernet ports can be enabled or disabled by management and
the corresponding administrative status can be displayed. When a port is
disabled, data is not received or transmitted through the port.

disabled, data is not received or transmitted through the port.
Monitoring Ports
Each port is continuously monitored and the current operational status of
the port (operating or not operating) can be displayed. Statistics on traffic
through the port are compiled and can be displayed at any time. These
include octets and frames (unicast, multicast, and broadcast) received and
transmitted on the port, as well as discarded frames with the reason for
discarding.
