Fast EtherHub 3500 System User’s Guide
2-14 Installing the System
Configuring a Manageable Stack
To manage the stack with the on-board configuration program
or any optional network management software, the stack must
include an EtherHub-12mi (i.e., a unit with an SNMP agent).
Moreover, the network management station must be able to
access the segment containing the management agent.
You should also consider adding a backup SNMP agent to
provide greater management reliability for critical applications.
The procedures required to install a backup agent is described
below.
Installing an SNMP Backup Agent
The on-board configuration
program only provides access
to the private MIB. To gain full
SNMP functionality, you must
use optional network
management software (e.g.,
AccView/Open).
Just add the backup agent(s) to the stack and let the system
automatically choose the Master agent and the Slave agent
based on longest up-time. The Master indicator on the device
chosen as the primary agent will turn ON. The Backup indicator
will turn ON for all other hubs (attached to the same segment)
that contain SNMP agents.
Note: If you attach SNMP agents to separate segments, be sure they
are assigned unique IP addresses via on-board configuration (as
described under
Changing the Segment Configuration
in Chapter 4).
