> RS-232 Port Configuration Mode Commands
> The RS-232 Port Configuration Mode is used to manage the RS-232 ports on the SPIO cards.
> default
> Restores the port’s default speed and communication mode.
> Product
> All
> Privilege
> Security Administrator, Administrator
> Syntax
> default { preferred slot | terminal { all | databits | flowcontrol | parity | speed | stopbits }
> 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.
> terminal { all | databits | flowcontrol | parity | speed | stopbits }
> Sets the terminal settings for the rs-232 port to their default settings.
> all: Restore all settings to their default values.
> databits: Restore the databits setting to its default value of 8.
> flowcontrol: Restore the flowcontrol setting to its default value of none.
> parity: Restore the parity setting to its default value of none.
> speed: Restore the speed setting to its default value of 9600.
> stopbits: Restore the stopbits setting to its default value of 1.
> Usage
> Restores port-level parameters to their default values.
> Example
> The following command restores all terminal settings to their default values:
> default terminal all
> end
> Exits the port configuration mode and returns to the Exec mode.
> Product
> All
> Privilege
> Security Administrator, Administrator
> Syntax
> end
> Usage
> Change the mode back to the Exec mode.
> exit
> Exits the port configuration mode and returns to the global configuration mode.
> Product
> All
> Privilege
> Security Administrator, Administrator
> Syntax
> exit
> Usage
> Return to the global configuration mode.
> preferred slot
> Assigns revertive or non-revertive control to port redundancy auto-recovery.
> Default: non-revertive operation
> Product
> PDSN, FA, HA, GGSN
> Privilege
> Security Administrator, Administrator
> Syntax
> preferred slot slot#
> no preferred slot slot#
> no
> Disables revertive, or auto-recovery, operation for selected port.
> slot#
> Identifies the physical chassis slot where the SPIO card is installed.
> Usage
> This command enables or disables revertive port redundancy, wherein 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.
> This command must be issued on a per port basis, allowing you to configure specific ports to be used on individual LCs or SPIO cards. For example, ports 1 through 4 could be configured as “preferred” on the LC in slot 17 while ports 5 through 8 are “preferred” on the LC in slot 33. In this scenario, both LCs would be in an Active operational state while still providing LC and port redundancy for the other.
> Important: This command is not supported on all platforms.
> Example
> preferred slot 24
> snmp trap link-status
> Enables/disables the generation of an SNMP trap for link status changes.
> 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 link status change traps when a monitoring facility can use the information or if there are trouble shooting activities are in progress.
> Example
> snmp trap link-status
> no snmp trap link-status
> terminal
> Configures the console port on the SPIO.

> Security Administrator, Administrator
> Syntax
> terminal { carrierdetect { off | on } | databits { 7 | 8 } | flowcontrol { hardware | none } | parity { even | none | odd } | speed { 115200 | 19200 | 38400 | 57600 | 9600 } | stopbits { 1 | 2 } }
> carrierdetect { off | on }
> Default:
> Specifies whether or not the console port is to use carrier detect when connecting to a terminal.
> databits { 7 | 8 }
> Default: 8
> Specifies the number of data bits used to transmit and receive characters.
> flowcontrol { hardware | none }
> Default: none
> Specifies how the flow of data is controlled between the SPIO and a terminal.
> parity { even | none | odd }
> Default: none
> Specifies the type of error checking used on the port.
> even - Enables error checking by setting the parity bit to 1 (if needed) making the number of 1s in the data bits even.
> none - Disables error checking.
> odd - Enables error checking by setting the parity bit to 1 (if needed) making the number of 1s in the data bits odd.
> speed { 115200 | 19200 | 38400 | 57600 | 9600 }
> Default: 9600
> Specifies the flow of data in bits per second between the console port and terminal.
> stopbits { 1 | 2 }
> Default: 1
> Specifies the number of stop bits between each transmitted character.
> Usage
> Sets the SPIO’s console port parameters for communication with the terminal device.
> Example
> The following command sets the SPIO’s console port. The terminal must support these values.
> terminal carrierdetect off databits 7 flowcontrol hardware parity even speed 115200 stopbits 1
