DECagent 90 Installation and Configuration

Introduction
The DECagent 90 network module (also referred to in this manual as the module)
is a Simple Network Management Protocol (SNMP) proxy agent for the
WorkGroup family. It has one ThinWire port and one console RS–232 port.
The DECagent 90 network module provides SNMP proxy support for the
DECbridge 90, DECbridge 90FL, DECserver 90L, DECserver 90L+,
DECrepeater 90C, DECrepeater 90T, DECrepeater 90FA, and DECrepeater 90FL.
As a proxy management agent, the DECagent 90 network module responds to
SNMP queries on behalf of those devices. The DECagent 90 accepts SNMP
data packets from the network management station (NMS) and translates them
into MOP/CC for the DECserver products and Remote Bridge Management
Software (RBMS) for the DECbridge products. DECrepeater modules are
managed on the DEChub management bus from the DECagent 90 or via a
DECbridge 90.
The DECagent 90 uses the autodiscovery feature and automatically finds all
devices (except DECserver 90L and DECserver 90L+) located in its community.
If a DECagent discovers a DECbridge in its community and the DECbridge is
managing a repeater, the DECagent begins managing any repeaters previously
managed by the DECbridge.
Management is accomplished using the DECagent 90 network module with a PC
or workstation that supports native SNMP, and HUBwatch software.
One DECagent 90 can manage as many as 16 interconnected hub communities
and 64 network modules. All hubs are identified by their unique community string.
The DECagent 90 accepts SNMP messages on behalf of its client network
modules, sends an appropriate command to the queried client network module,
and waits for a response from the client network module. After receiving a
response from the client network module, the DECagent 90 sends an SNMP
response to the querying NMS.
The DECagent 90 has a single IP address. It implements the protocols required
for SNMP-based proxy access.
System managers using HUBwatch software with the DECagent 90 can manage
their network from a PC workstation connected to the hub. They can access and
query the network at any level from an individual port to the overall network
structure.

DECagent 90 Installation and Configuration

Configuring the Module
Setup Port Description
The setup port allows you to access and set DECagent 90 parameters when the
module is initially installed, and provides two methods of using out-of-band
management. This section describes how to access the module from the setup
port on the DECagent 90.
The signals from the DECagent 90 setup port conform to the EIA-232D signaling
standard from 600 baud to 19.2k baud. The DECagent 90 provides an autobaud
feature which sets the module port speed to the same baud rate as the setup port
device. To the user, the port appears as a data terminal equipment (DTE) device.
The DECagent 90 allows you to set the IP address by using BOOTP services, or
by selecting option 4 in the Agent Installation Menu. All other Agent Installation
Menu options can be configured using Hubwatch.

Setup Port Cabling
The setup port on the DECagent 90 is a DB25 connector that can be connected
to a setup port device (a terminal or personal computer), using the following
cables and adapters.
Cable/Adapter Type1

Connecting Device

BC16E-xx/H8575–A

2 BC22D is a standard 25-pin to 25-pin D-Sub null-modem cable.

DECagent 90 Installation and Configuration

Configuring the Module (Cont.)
Accessing the Setup Port on the Module
To access the setup port on the DECagent 90 module, do the following:
1. Connect the setup port device cable to the setup port connector on the
DECagent 90.
2. Press Return on the setup port device a few times until the DECagent 90
Agent Installation Menu appears.
NOTE:

If a password is set, you are required to enter the password to
access the Agent Installation Menu. The factory default is no
password.

Optional Setup Procedures
Once the Agent Installation Menu appears, you can configure the module by
performing any of the following steps.
1. Select menu option 4, Set Agent IP Address/Gateway, and enter an IP
address. If you want to obtain the IP address using BOOTP services, then
leave the IP address set to the default of 0.0.0.0. If trap destinations
extend beyond the subnet, you must enter a default gateway address.
2. If you need to change the read/write community string from the default value
of PUBLIC, select menu option 5, Set Agent Read/Write Community. You
can also change the read/write community string by using an SNMP
manager, such as HUBwatch.
3. If you want to add trap addresses, select menu option 6, Add/Remove Trap
Address. You can also modify the trap addresses by using an SNMP
manager such as HUBwatch. If trap destinations extend beyond the subnet,
you must enter a default gateway address by selecting menu option 4, Set IP
Address/Gateway.
NOTE:

If a DECagent 90 is configured in a DEChub 90, it discovers
other modules in the hub except for a DECserver 90L and a
DECserver 90L+. You must add these two module types
manually by using an SNMP manager, such as HUBwatch.

DECagent 90 Installation and Configuration

Configuring the Module (Cont.)
Configuring Additional Hubs
The DECagent 90 is capable of managing up to 16 communities and up to 64
modules. A community can consist of an 8- or 16-slot DEChub 90, or an arbitrary
grouping of standalone modules. The grouping of standalone modules is useful if
you are managing more than 16 standalone DECserver 90L modules, for
example. Configuring additional communities is accomplished by using an SNMP
manager, such as HUBwatch.

Affecting Configuration Changes
The DECagent 90 provides nonvolatile storage of port name and administrative
status parameters for all proxied repeater modules. Therefore, if a repeater is
removed from a DEChub and the parameters have changed from their default
values, the DECagent 90 saves the parameter status and uses it when the
repeater is reinstalled in the same slot.
If a module other than a repeater is reinstalled in the slot, the DECagent 90 does
not accept this new module, and a conflict message is displayed (both via
readable SNMP objects and by the issuing of an SNMP trap). The DECagent 90
maintains the integrity of any manually set status information until the information
is changed by the SNMP manager.
If you remove the initial repeater status information, the module can be removed
from the DEChub. If a new module has replaced that repeater, it would be
discovered at that time. If a repeater is removed from the hub, and the port
names and administrative status remain at default values, then the repeater will
be automatically removed from the configuration on the next poll cycle.
The DECserver 90L and early versions of the DECserver 90L+ are not
autodiscovered, and you must manually add the module by using an SNMP
manager, such as HUBwatch. Because these modules are added manually, you
must ensure that they are installed into the correct DEChub and the correct
DEChub slot; otherwise they eventually cause conflicts. You can resolve these
conflicts by removing the DECserver 90L or DECserver 90L+ and then installing it
in its correct location.
If you remove a DECserver 90L or a DECserver 90L+ from one hub and install it
in another hub, you must manually delete it from its previous location and then
add it to its new location by using an SNMP manager, such as HUBwatch.

DECagent 90 Installation and Configuration

Configuring the Module (Cont.)
Two Methods of Using Out-Of-Band Management
The DECagent 90 provides you with two methods of using out-of-band
management.

•

By using Agent Installation Menu options 13, 14, and 15, you can manage all
devices listed in the Introduction section. Menu option 13 views module
information, including module reachability and individual port status. Menu
option 14 manages DECrepeater 90 modules. Menu option 15 manages
DECbridge 90 modules or DECserver 90L or DECserver 90L+ modules.

•

By using Agent Installation Menu option 12, you can switch the setup port into
SLIP mode. In this mode, the setup port does not access the setup menu
options, but instead provides a SLIP connection over which an SNMP manager
communicates with the DECagent 90. The physical connection from the
DECagent 90 setup port can be a direct line to the network management station
by use of a modem, or by use of a serial line to a terminal server that supports
SLIP.

Problem Solving Using the LEDs
Table 2 lists the typical states of the LEDs for various error conditions that can
occur during initial installation of the device, along with probable causes and
corrective actions to take.

Initial Powerup
When power to the the module is initially turned on, the following events occur:
1. The Power LED lights and remains lit. All other LEDs light briefly and then
turn off. This verifies that the individual LEDs are operational (defective LEDs
do not light).
2. After the successful completion of self-test, the Module OK LED lights and
remains lit.
3. The remaining LEDs (Network OK and Network Activity) now indicate their
operational status, as described in Table 2.
Table 2: Problem Solving Using the LEDs
Symptom

Probable Cause

Power LED is off. The module is not
receiving +5Vdc.

Corrective Action
Check the power LED on the
DEChub 90.
If power LED is lit, reseat or remove
the module.
Inspect the module’s 48-pin connector
for bent, broken, or dirty pins.
If the module is in a standalone
configuration, check all power supply
connections.
If the problem persists, replace the
module.

Accessing MIBs and RFCs
This section describes how to access Digital’s private Management Information
Base (MIB) and Request For Comments (RFCs).
Public MIBs can be accessed over the Internet network using any of the following
methods:

•

Electronic mail

•

ftpmail

•

Anonymous ftp

You can use these methods to access up-to-date MIBs, as described in the
following sections.

Using Electronic Mail
The DDN Network Information Center (NIC) of SRI International provides
automated access to NIC documents and information through electronic mail.
This is especially useful for people who do not have access to the NIC from a
direct Internet link, such as BITNET, CSNET, or UUCP sites.
To use the mail service, follow these instructions:
1. Send a mail message to SERVICE@NIC.DDN.MIL.
2. In the SUBJECT field, request the type of service that you want, followed by
any needed arguments.
Normally the message body is ignored, but if the SUBJECT field is empty,
the first line of the message body is taken as the request. The example at the
end of the Using ftpmail section lists some of the services available.
Requests are processed automatically once a day. Large files are broken down
into separate messages. However, a few files are too large to be mailed.

DECagent 90 Installation and Configuratioin

Accessing MIBs and RFCs
Using ftpmail
Digital offers Internet ftpmail access to private MIB information, in ASCII text
form, at GATEKEEPER.DEC.COM, with up-to-date documents stored in the
directory /private/mib. Check the INDEX file and the README file for the
current contents.
To use ftpmail, follow these instructions:
1. Send a mail message to ftpmail@gatekeeper.dec.com.
2. Ignore the subject line.
3. Include the word “connect” in the first line of the body.
4. Include get commands for each document required, for example:
get /private/mib/README
Requests are acknowledged, then queued and processed every 30 minutes.
Because of the number of requests, it may take a day or two before you receive a
reply.
NOTE
For more timely access, consider using anonymous ftp (refer to the Using
Anonymous ftp section).
