Cabletron Systems DMS-100 manual EIU datafill

90Chapter 3: EIU datafill

•The first two fields for the tuple are numbers between 0 (zero) and 32 767 that represents the maximum IP transmit-and-receive rate in kbyte/s to and from the node that is datafilled as a key.

•The IP throttling numbers default to zero (100% throttling) for all EIUs datafilled in table LIUINV. This means that if the throttling capacity numbers are not modified to numbers more than zero in this table, the EIU cannot communicate to nodes across DS30 links. The APU datafill is optional in this table. If APU is not datafilled in this table, it defaults to 0% throttling. The 0% throttling means that IP traffic to and from the APU is not throttled.

•There are eight optional fields for each tuple.

•Each optional field contains the following:

—SuperNode node name, such as CM, file processor (FP), application processor (AP), EIU, or APU

—node index

—transmit capacity in kbytes/s

•Each optional field indicates the IP transmission rate from the node in the optional field to either the EIU or the APU that is datafilled as a key for the tuple.

•The node name and index in the optional field must be datafilled first in its appropriate inventory table. However, table IPTHRON does not validate the information in the optional field. For example, FPs datafilled in the IPTHRON tuple optional fields must be datafilled first in table APINV. The tuple in IPTHRON is accepted even if the FPs are not datafilled in table APINV.

•For one tuple, the total transmit capacity of all of the nodes in the optional fields cannot exceed the total receive capacity of the LMS node.

•For one tuple, the same node and node number must not appear more than once in the optional fields.

•No other verification is performed for a tuple. For example, maintenance personnel must ensure that EIUs and APUs that appear in the optional fields are not located on the same LIM as the LMS node.

•The table entries can be added, modified, or deleted without taking the node off-line. The node must be datafilled in table LIUINV before it is allowed in table IPTHRON. As a special case, EIUs are automatically datafilled in this table with default values (transmit capacity of zero and receive capacity of zero) when they are added in table LIUINV. The EIU is also automatically deleted from IPTHRON when it is deleted from table LIUINV. Adding and deleting EIU directly from table IPTHRON is not allowed.

•The table does not directly depend on the other tables.
