Installing the Ethernet Subagent

Run the Distributed Systems Management/Software Configuration Manager

(DSM/SCM) product to install the SNMP agent and the Ethernet Subagent.

Then load the ASN.1 source code for the Ethernet Subagent’s private MIB onto any

SNMP manager station from which you want to monitor Ethernet resources. The MIB

definitions are contained in two files:

•

RFC 1643, Definitions of Managed Objects for the Ethernet-like Interface Types,

contains definitions for the dot3 Statistics group MIB objects.

•

The ZESAMIB file contains definitions for the private Ethernet Subagent MIB

objects defined by HP.

Compile the ZESAMIB file (and, if necessary, the RFC1643 file) as described in the

documentation provided with your SNMP manager. Compiling the MIB makes it

possible for the SNMP manager to display the names (rather than only numeric object

identifiers) of MIB objects.

Once the MIB definition files have been compiled, you can start the Ethernet Subagent.

Before Starting the Ethernet Subagent

The SNMP agent must be running before you start the Ethernet Subagent. Start the

SNMP agent with the RUN command, as described in Section 2, Installing and

Configuring the SNMP Agent. For example:

RUN SNMPAGT /NAME $agent-process, NOWAIT/

If the SNMP agent is not available when the Ethernet Subagent is started, the

subagent fails to start. If the SNMP agent disappears after the Ethernet Subagent

starts, the subagent enters a loop trying to reconnect to the SNMP agent at the rate

specified in its zesakeepAliveTimer object.

In addition, the SCP process ($ZNET, or the SCP process specified for the -s startup

parameter) must be running. If the SCP process is not available, the Ethernet

Subagent enters a loop trying to reconnect to it at the rate specified in its

zesaKeepAliveTimer object.

Note. You can access the Ethernet Subagent’s private MIB objects regardless of the status of

the SCP process.
