BITS Port Configuration Mode Commands


BITS Port Configuration Mode Commands
 
 
The Building Integrated Timing Supply (BITS) port configuration mode provides the commands to configure the BITS ports on the SPIO and optionally to configure the transmit timing source.
 
Important: The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).
 
default
Restores the port’s default speed and communication mode.
Product
SGSN
Privilege
Security Administrator, Administrator
Syntax
default { mode | preferred slot }
mode
Sets the default for the ports framing mode. The default is no mode configuration.
preferred slot
Sets the port for non-revertive operation for port redundancy auto-recovery; requiring an administrative user to manually issue a port switch to command to return service to the original port.
Usage
Restores port-level parameters to their default values.
Example
default preferred slot
 
description
Defines descriptive text that provides useful information about the port.
Product
SGSN
Privilege
Security Administrator, Administrator
Syntax
description text
no description
no
Erases the port’s description from the configuration file.
text
text must be a string of 1 to 79 alphanumeric characters with no spaces or a string within double quotes that includes printable characters. The description is case-sensitive.
Usage
Set the description to provide helpful information, for example the port’s primary function, services, end users. Define any information, the only limit is the number of characters.
Example
description samplePortDescriptiveText
description “This is a sample description”
 
end
Exits the BITS port configuration mode and returns to the Exec mode.
Product

Privilege
Security Administrator, Administrator
Syntax
end
Usage
Change the mode back to the Exec mode.
 
exit
Exits the BITS port configuration mode and returns to the Global configuration mode.
Product
SGSN
Privilege
Security Administrator, Administrator
Syntax
exit
Usage
Return to the Global configuration mode.
 
mode
Configures the framing mode for the port.
Product
SGSN
Privilege
Security Administrator, Administrator
Syntax
mode { e1 | t1 } framing type
e1 | t1
e1 selects the SDH E1 framing mode.
t1 selects the SONET T1 framing mode.
framing type
basic selects the Frame Alignment Signal (FAS) used with E1.
crcmf selects the Multiframe with CRC (FAS+CRC) used with E1.
esf selects the extended superframe format used with T1.
sf select the superframe format (D4) used with T1.
Usage
Set the ports framing mode parameters.
Example
Configure the port to support E1 with crcmf framing.
mode e1 framing crcmf
 
preferred slot
Identifies which card in a chassis should assume revertive (redundancy auto-recovery) functionality should the slot/port being configured go down. There are only two SPIO, one in slot 24 and the other in slot 25.
Product
SGSN
Privilege
Security Administrator, Administrator
Syntax
preferred slot slot#
[ default | no ] preferred slot
default
Default: non-revertive operation.
no
Disables revertive, or auto-recovery, operation for the port.
slot#
Identifies the physical slot in the chassis where the SPIO is installed.
Usage
This command enables or disables revertive port redundancy. So after a port failover, when the original port is restored to service (i.e. link up) the system will return service to that port automatically.
Disabled, which is the default setting, causes non-revertive operation; requiring an administrative user to manually issue a port switch to command to return service to the original port.
Example
preferred slot 25
 
recover
Configure line-timing so the SPIO recovers the transmit timing source from an external source via one of the line cards in the chassis. The recovered clock is then distributed for use to all line cards in the chassis.
Product
SGSN
Privilege
Security Administrator, Administrator
Syntax
recover { line1 slot# | line2 slot # }
no recover { line1 | line2 }
no
Deletes the identified line-timing source definition from the configuration.
line1 slot#
Sets first priority for line-timing clock recovered from the line card in the specified slot.
slot#: a number between 1 and 48.
line2 slot#
Sets second priority for line-timing clock recovered from the line card in the specified slot.
slot#: a number between 1 and 48. Can not be the same slot number entered for line1.
Usage
Define which line-timing source has priority.
Example
Configure the line card in slot 19 as the preferred line-timing source.
recover line1 19
 
shutdown
Terminates all processes supporting the port or blocks the shutting down of the port. Conversely, this command with the no keyword enables the port and BITS -timing as a transmit timing source.
Product
SGSN
Privilege
Security Administrator, Administrator
Syntax
shutdown
no shutdown
no
Enables the port’s administrative state. When omitted the card is shutdown (removed from service).
Usage
Shut down a port prior to re-cabling and/or other maintenance activities.
This command with the no keyword is required to bring a port into service.
Example
shutdown
no shutdown
 
snmp trap link-status
Enables/disables the generation and sending of an SNMP (notification) trap when the port experiences a change of state (up or down).
Product
All
Privilege
Security Administrator, Administrator
Syntax
snmp trap link-status
no snmp trap link-status
no
Disables the sending of traps for link-status changes.
Usage
Enable the sending of link-status change traps if there is a monitoring facility that can use the information or if there are troubleshooting activities in progress.
Example
snmp trap link-status
no snmp trap link-status
