Chapter 3: EIU datafill
This chapter describes the datafill requirements for installing and maintaining
Ethernet interface units (EIU) in an Ethernet network. There are seven data
schema tables required to provision the EIU. The purpose of each table is
summarized in table 10.
Table 10 Summary of data schema tables required for EIU provisioning
Table Description
LIUINV Table LIUINV is the main inventory table for configuring EIUs, and includes card
product engineering codes (PEC), shelf location, default load name, Ethernet
MAC address, and a flag to enable local area network (LAN) heartbeat checking.
IPNETWRK Table IPNETWRK defines the SuperNode subnetwork (IP address class, DMS-
core host address, subnetwork mask, and default EIU). The SuperNode subnet
is derived from the subnet mask and the DMS-core host address.
IPROUTER Table IPROUTER defines the routing functions of the EIUs (SuperNode side and
LAN side IP addresses, and flags to enable address resolution protocol (ARP)
and proxy ARP protocols).
IPHOST Table IPHOST defines IP addresses for all IP hosts in the switch. Hosts include
computing module (CM), application processors (AP), file processors (FP),
application processors for UNIX (APUX), and the EIU.
IPPROTO Table IPPROTO defines timers for ARP refresh.
IPTHRON Table IPTHRON defines IP throttling data in kbyte/s for the EIUs and APUs. Table
entries allow favoring of the CM, APs, and FPs. This table protects the DS30 links
in the LPP from traffic overflow, and is needed for messaging.
ENSITES Table ENSITES contains a complete list of all sites referenced in table EXNDINV.
ENTYPES Table ENTYPES contains a complete list of all external node types referenced in
table EXNDINV.
EXNDINV Table EXNDINV lets the maintenance and administration position (MAP) operator
monitor and control nodes that are either attached to SuperNode switches by EIU,
or attached to SuperNode or NT40 switches by an input/output controller (IOC)
X.25 card.
