Managing the LAN Node Databases

Managing the LAN Device Databases  

Typically, each database contains the same devices. However, the permanent database may contain entries for devices that have not yet been configured or installed in the system. The LANACP LAN server process maintains the volatile device database. The LANCP utility maintains the permanent device database. You can manipulate either database using the LANCP utility commands depending on your user privileges, as follows:

• Privileged users can add or delete device entries from each database, enable or disable MOP downline load service, and clear MOP downline load counters information for LAN devices.



• Unprivileged users can view the MOP downline load status and counters information.

The following sections describe how to enter and remove devices from the LAN permanent and volatile device databases, and how to enable and disable MOP downline load services.

Displaying Devices in the LAN Device Databases  

To display information in the LAN permanent device database, enter the LIST DEVICE command using the following syntax:LIST DEVICE device-name [/qualifiers]

To display information in the LAN volatile device database, enter the SHOW DEVICE command using the following syntax:SHOW DEVICE device-name [/qualifiers]

LIST DEVICE and SHOW DEVICE Command Qualifiers provides a brief description of the LIST DEVICE and SHOW DEVICE qualifiers.

Table 14   LIST DEVICE and SHOW DEVICE Command Qualifiers

Qualifier	Description
/ALL	Lists, or shows all devices which match device names.
/CHARACTERISTICS or PARAMETERS	Displays status and related information about the device.
/COUNTERS1	Displays device counters.
/DLL or MOPDLL	Lists or shows downline load characteristics.
/MAP	Displays the current configuration of the Token Ring functional address mapping table.
/OUTPUT=file-name	Creates the specified file and directs output to it.
/REVISION	Displays the current firmware revision of the adapter, if available or applicable.
/SR_ENTRY	Displays the contents of the current Token Ring source routing cache table.

If you do not specify a qualifier, the utility displays the matching devices without additional information.

Entering Devices into the LAN Device Databases  

To enter a device into the LAN permanent device database or to modify an existing entry, enter the DEFINE DEVICE command using the following syntax: DEFINE DEVICE device-name [/qualifiers]

To enter a device into the LAN volatile device database or to modify an existing entry, enter the SET DEVICE command using the following syntax: SET DEVICE device-name [/qualifiers]

Deleting Device Data from LAN Device Databases  

To delete device data from the LAN permanent device database, enter the PURGE DEVICE command using
the following syntax: PURGE DEVICE device-name [/qualifiers]

If no qualifier is present to select the type of data to delete, the entire device entry is deleted.

PURGE DEVICE Qualifiers provides a brief description of the PURGE DEVICE qualifiers.

Table 15   PURGE DEVICE Qualifiers

Qualifier	Description
/ALL	Deletes data for all LAN devices in the LAN permanent device database. If you specify a device name, all matching LAN devices are selected, for example: E to select all Ethernet devices, F for FDDI, I for Token Ring, EW to select all Ethernet PCI Tulip devices.
/CHARACTERISTICS or PARAMETERS	Deletes device characteristics settings for the LAN device, such as speed, duplex mode, and other device parameters.
/DLL or MOPDLL	Deletes MOP downline load settings for the LAN device.
/TRACE	Deletes driver tracing settings for the LAN device.

Example

1. LANCP> PURGE DEVICE/ALL

   This command deletes all device data from the LAN permanent device database.

1	SHOW DEVICE only
