Table 5-1. Network Interface Options (4 of 7)

Management Link
Possible Settings: Disable, FDL, DDL
Default Setting: Disable
Specifies the network management link.
NOTES: If both FDL and DDL are not available selections, the configuration
option is set to Disable and cannot be edited.
If Management Link for the local T1 access unit is set to FDL or DDL,
configure the remote T1 access unit with the same settings.
Disable – Does not use the management link.
FDL – Uses FDL as the management link. FDL allows IP management traffic to flow
over the 4 kbps data link provided by the FDL. FDL requires an end-to-end FDL
connection and cannot be terminated within the network.
FDL does not appear if:
Line Framing Format is set to D4.
EDL on any synchronous data port is set to Enable.
DDL – Uses DDL as the management link.
DDL does not appear if all network time slots are assigned.
IP Address
Possible Settings: 000.000.000.000 – 223.255.255.255, Clear
Default Setting: 000.000.000.000
Specifies the internet protocol address for the management link.
IP Address only appears if Management Link is set to FDL or DDL.
000.000.000.000 – 223.255.255.255 – The IP address for the management link which
you can view or edit. The first digit (i.e.,
xxx
.255.255.255) cannot be 0 or 127, or greater
than 223. However, 000.000.000.000 is valid, representing a null address.
Clear – Resets the IP address and fills the address with zeros.
Subnet Mask
Possible Settings: 000.000.000.000 – 255.255.255.255, Clear
Default Setting: 000.000.000.000
Specifies the subnet mask for the management link.
Subnet Mask only appears if Management Link is set to FDL or DDL.
000.000.000.000 – 255.255.255.255 – The subnet mask for the management link which
you can view or edit.
Clear – Resets the node subnet mask and fills the address with zeros
(i.e., 000.000.000.000). When the subnet mask is all zeros, the IP protocol creates a
default subnet mask based on the class of the IP address: Class A: 255.000.000.000,
Class B: 255.255.000.000, or Class C: 255.255.255.000.
