b. Define the following fields:
Table 3-26: IP SPAN Dialog Box Options
Field Description
Circuit ID The circuit identification is a number used to identify
the card’s span, it can be any whole number between
0 to 65535. This number is assigned to a specific IP
address. Therefore, when defining several spans
(different cards) each should be assigned a different
Circuit ID number.
The circuit ID must be unique per MCU.
The Circuit ID is used later to assign this Network
Service to the IP card (see “Assigning Network
Services to the IP/IP+ Cards” on page 3-93).
IP Address The IP address of the IP network interface card
installed in the MCU. Each card has a specific IP
address. This address is assigned to the Circuit ID.
If the DHCP option is selected for this Network
Service, this field is disabled, and shows the address
0.0.0.0, as the IP address will be retrieved from the
DHCP.
Communication
Mode Indicates the data transmission rate and duplex
mode. When set to
Auto the system synchronizes the
data transmission rate according to the network. You
can also force the router to connect to the IP card
installed in the MCU at the following data
transmission rates according to the network’s
capabilities:
• 10 Mb Half Duplex
• 10 Mb Full Duplex
• 100 Mb Half Duplex
• 100 Mb Full Duplex
Full Duplex refers to the transmission of data in two
directions simultaneously.
Half Duplex refers to the transfer of data in only one
direction at a time.
