The IP SPAN dialog box opens.
This dialog box is used to define the IP card to which the IP network
is connected and that should be used with this Network Service.
b. Define the following fields:
Table 3-16: IP SPAN Options
Field
Circuit ID
Chapter 3 - Initial System Configuration
Description
The Circuit ID is the connection between the span
and the card; it identifies the specific span and IP
address with a number, which you use afterwards
when assigning the Network Service to the IP card.
Enter any whole number between 0 to 65535 as the
circuit identification.
When defining several spans (different cards) each
should be assigned a unique Circuit ID number.
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 3-50).
