-
Configured IP Address field:
Specifies the configured IP address and mask length for the interface and allows you to turn on/off the interface administratively.
-
Example: 10.1.12.22/30
-
Options: on, off
-
Default: on
-
New IP Address field:
Specifies the IP address for the interface. When you enter the first IP Address and mask length, then click Apply, the configured IP address and mask length display, and this field remains blank to allow the addition of secondary addresses. Note: Secondary addresses do not apply to serial interfaces. If you enter a new IP address and press Apply for a serial interface, an error message displays.
-
Example: 10.1.12.22/30
-
Range: Valid IP address and mask for the network.
-
New Subnet Mask field:
Specifies the network mask length for this interface. In general, specify 30 for networks connecting an IP Switch with another IP Switch or IP Switch Processor. The mask length is commonly 24 for other networks. When you enter the first IP Address and mask length, then click Apply, the configured IP address and mask length display, and this field remains blank to allow the addition of secondary addresses. Note: This field does not apply to serial interfaces. If you enter a new mask length and press Apply for a serial interface, an error message displays.
-
Remote Address field:
Specifies the IP address at the other end of a point-to-point link, used with RFC1483 (PVCs), IFMP, and serial interfaces. You must specify an IP address at both ends of the link (unnumbered interfaces are not supported).
-
Example: 10.1.12.22/30
-
Range: Valid IP address for the network.
-
Encaps type field:
Specifies the encapsulation type. When using Cisco HDLC as the encapsulation type, the system sends keep-alive packets every 10 seconds. The remote end of the link must also be configured to send keep-alive messages every 10 seconds or the link state will fluctuate.
-
Options: Cisco HDLC, PPP
-
Default: PPP
-
X.21 Interface field:
Specifies whether or not a serial interface is X.21. When configuring an X.21 interface, this field must be set to On for the driver to work properly. Note: This field should be changed on the local end only when the interface is down. If you change it while the interface is up, the new setting does not take effect until the interface is disabled and then enabled again. Changing the setting at the remote end has no effect.
-
Options: On, Off
-
Default: Off
-
Internal Clock field:
Specifies whether or not the card generates the clock for the line. Internal clocking is used when connecting point-to-point to another machine using a mechanism that does not provide an external clock source, such as a null modem cable. If you select On for this field, you must also set the Baud Rate (bps) field. If this field is set to Off, the Baud Rate (bps) field can remain unspecified. If both ends of the point-to-point link have to provide a clock source, they should
-
Options: On, Off
-
Default: Off (external clock used)
-
Baud Rate (bps) field:
Specifies the baud rate to be used by the driver. This field is required if the Internal Clock field is set to on. If the Internal Clock field is set to Off, this field can remain unspecified. If both ends of the point-to-point link have to provide a clock source, they should both set their clocks to the same baud rate.
The driver selects the standard baud rate closest to the number you specify in this field. The following table shows the user's desired baud rate mapped to the actual bit rate generator (BRG) clock rate. Because of the algorithm used, in certain circumstances only approximate values can be generated. Each entry consists of three elements: baud rate (bps), TMC, and BR.
Baud Rate = FCLK/TMC/2^BR
