Ethernet Subagent
The name of the TCP/IP process specified for the subagent's private
zesaTcpIpProcess MIB object
The name of the SCP process specified for the subagent's private
zesaScpProcess MIB object
The name of the SNMP agent process specified for the subagent's private
zesaAgentName MIB object
This information is displayed only if the value of the ZEMS-TKN-CHANGE-
REASON is ZEMS-VAL-UNDERLYING-FAILED.
code-location/internal-context-text
indicates where in the subsystem or application code the fault occurred.
ZEMS-VAL-NULL
indicates the type of subsystem defined event. Because the Ethernet Subagent
process has not defined this as a private event, the DDL AS clause "undefined"
always appears in the message text following "user content."
Cause. The Ethernet Subagent process lost its connection to the configured TCP/IP
process (zesaTcpIpProcess), the SCP SPI interface process (zesaScpProcess), or the
SNMP agent process (zesaAgentName).
If the underlying object is the SNMP agent process (zesaAgentName), the subagent
has lost its connection to the agent process and has temporarily disconnected the
TCP/IP interface to conserve resources.
Effect. Values for the MIB objects supported by the Ethernet Subagent are not
computed. SNMP requests for these MIB objects receive an SNMP-ERR-GEN-
ERROR response. Private MIB objects supported by the Ethernet Subagent can still be
accessed.
Recovery. If the underlying object is the TCP/IP process or the SCP process, use
SCF or the STATUS command to check the operating state of the TCP/IP or SCP
process. The subagent attempts to reacquire the TCP/IP connection according to the
value of its zesaKeepAliveTimer object.
If no error conditions are found in the TCP/IP and SCP processes, or if the subagent
fails to reacquire the SCP interface, stop and restart the subagent with a different SCP
process.
If the underlying object is the SNMP agent process, check the operating state of the
SNMP agent process. If necessary, restart the SNMP agent. The Ethernet Subagent
attempts to reconnect to the SNMP agent at the rate indicated by its
zesaKeepAliveTimer object.
