Cabletron Systems DMS-100 manual Interdependency and auto-configuration, Table Liuinv

68Chapter 3: EIU datafill

The following sections describe these tables as they apply to EIU provisioning. For complete information on data schema, refer to DMS-100 Translations Guide, 297-8xxx-350.

Interdependency and auto-configuration

Tables IPROUTER and IPHOST are interdependent on each other, as well as on table IPNETWRK. Whenever a tuple in table IPROUTER is modified, the corresponding tuple, if any (with the same EIU), in table IPHOST is also modified and auto-configured. For example, if either the SuperNode side or the LAN-side IP address changes for an EIU in table IPROUTER table, the corresponding entry in table IPHOST is configured to reflect the changes made in table IPROUTER. The changes in the tables are propagated immediately to all in-service nodes.

Changes made to the IP address component in table IPNETWRK also force auto-configuration of the IP address components of all the nodes listed in tables IPROUTER and IPHPOST. The auto-reconfiguration routine validates the changes made in table IPNETWRK against the current entries in tables IPROUTER and IPHOST. If the new parameters of IPNETWRK table do not conform with all the current entries in the other two tables, auto-configuration is not performed and the reasons are displayed.

The validation routine for auto-configuration validates the host IDs of all the nodes in tables IPHOST and IPROUTER with the new host ID size being proposed in table IPNETWRK. The changes cannot be made to table IPNETWRK if the validation for auto-configuration fails. If the changes are validated for auto-configuration, the modified data in table IPNETWRK is propagated to all nodes along with the modified data (as a result of auto- configuration) of tables IPROUTER and IPHOST.

Boot protocol (BOOTP) may automatically datafill the FPs in table IPHOST even though EIUs are datafilled automatically.

Table LIUINV

Table LIUINV describes the hardware configuration for application-specific units (ASU). EIU hardware information is datafilled in this table.

Currently, the system allows a maximum of eight EIUs per switch. EIUs can be on a single link peripheral processor (LPP) or in multiple LPPs (according to the limitations imposed by product integrity testing of the engineering rules in Provisioning Rules for LPP, SSLPP, and SNSE LIS, System Engineering Bulletin SEB 92-02-001. The location of an EIU on an LPP or on a particular shelf of the LPP must be carefully considered with respect to LPP engineering rules. For more information on engineering, refer to “Chapter 1: Introduction to the EIU”.
