Alias
|
Description of the interface; 0-15 characters; default: blank
|
IfIndex
|
Identifier for the interface on the particular line interface; generated automatically
|
Operational
|
Current operational status of the interface

Desired status of the interface: Up/Down; default: Up
|
Transmit Clock
|
- Loop Timing—device receives its clocking from a network source
- Internal Module—device receives its clocking from a network source
- Internal Chassis—device receives its clocking from the configured system clock
|
Sonet Path Speed
|
- Speed for SONET paths generated on the line interface
- OC3—Creates an OC3 SONET path with three DS3 channels on top of the line interface
- OC1—Creates three OC1 paths on top of the line interface
- Unspecified—Does not allow you to create or delete anything on the interface
- Enabled only when SDH is selected for synchronous mode
- Disabled if there are any DS3 or DS1 interfaces on the line interface
- Not visible for cOC12 line modules
|
Synchronous Mode
|
- SONET—Synchronous Optical Network
- disables Sonet Path Speed field and sets to it OC1
- SDH—Synchronous Digital Hierarchy
- enables Sonet Path Speed field
|
Loopback Mode
|
- No Loopback—Disables loopback mode
- Line Loopback—Loops the data toward the network; connects the received network signal directly to the transmit network signal line
- Internal Loopback—Loops the data toward the interface of the module; connects the local transmitted signal to the local received signal
