ipNetToMediaTable Maintenance
When the TCP/IP Subagent finds that a ROUTE object has been deleted or added, it
removes or adds the corresponding ipRouteTable entry.
ipNetToMediaTable Maintenance
The TCP/IP Subagent builds entries by sending an INFO SPI command for the
SUBNET object. For each subnet found, the TCP/IP Subagent extracts the subnet type
and the associated I/O process name.
Then, using the I/O process name, the TCP/IP Subagent sends the necessary INFO
SPI commands for the PORT object. The values found in the ZTCI-DDL-INFO-
SUBNET and the ZLAM-DDL-INFO-PORT and lmPifAttr structures is mapped into the
appropriate MIB objects.
If the TCP/IP Subagent finds a change in the subnet configuration while building the
ipNetToMediaTable, it also updates the indexes in the ifTable and the ipAddrTable.
When the TCP/IP Subagent finds that a SUBNET object has been deleted or added, it
removes or adds the corresponding ipNetToMediaTable entry.
ICMP Group
The ICMP group contains information about the Internet Control Message Protocol
(ICMP) layer of the TCP/IP subsystem being managed.
The ICMP group consists of a collection of scalar objects. The objects identified by a
check mark in the following list are objects for which there is corresponding HP TCP/IP
subsystem instrumentation:
iso (1)
identified-organization (3)
dod (6)
internet (1)

mib-II (1)
