tcpConnTable Maintenance
tcpConnTable Maintenance
The TCP/IP Subagent builds entries by sending a STATUS SPI command to the
PROCESS object, using the name of the TCP/IP subsystem being managed
(ztsaTcpIpProcess). It then maps the values found in the ZTCI-DDL-STATUS-
PROTO structure into the appropriate MIB objects. The ZTCI-DDL-STATUS-PROTO
structure returns connection information for both TCP and UDP. The subagent ensures
that only the TCP connections are selected. Instances of object types that represent
information about a particular TCP connection are transient. They persist only as long
as the connection in question.
Rebuilding the tcpConnTable also causes the indexes in the udpTable to be updated.
UDP Group
The UDP group contains information about the User Datagram Protocol (UDP).
The UDP group consists of a collection of scalar objects and one table (udpTable). 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)
mgmt (2)
mib-II (1)
udp (7) √
udpInDatagrams (1) √
udpNoPorts (2)
udpInErrors (3) √
tcpConnState Partial See Table 8-11 for description of retrievable
information. The MIB-II value 12 (delete TCB) is not
supported in this implementation; attempts to set
this object to any value return a badValue error.
tcpConnLocalAddress Yes See Table 8-11

returned.
