SNMP Settings

The Simple Network Management Protocol (SNMP) lets a network administrator monitor

problems on a network by retrieving settings on remote network devices. The network

administrator typically runs an SNMP management station program on a local host to

obtain information from an SNMP agent such as the Netopia Gateway.

set snmp community read

name

Adds the speciﬁed name to the list of communities associated with the Netopia Gateway.

By default, the Netopia Gateway is associated with the public community.

set snmp community write

name

Adds the speciﬁed name to the list of communities associated with the Netopia Gateway.

set snmp community trap

name

Adds the speciﬁed name to the list of communities associated with the Netopia Gateway.

set snmp trap ip-traps

ip-address

Identiﬁes the destination for SNMP trap messages. The

ip-address

argument is the IP

address of the host acting as an SNMP console.

set snmp sysgroup contact

contact_info

Identiﬁes the system contact, such as the name, phone number, beeper number, or email

address of the person responsible for the Netopia Gateway. You can enter up to 255 char-

acters for the

contact_info

argument. You must put the

contact_info

argument in

double-quotes if it contains embedded spaces.

set snmp sysgroup location

location_info

Identiﬁes the location, such as the building, ﬂoor, or room number, of the Netopia Gateway.

You can enter up to 255 characters for the

location_info

argument. You must put the

location_info

argument in double-quotes if it contains embedded spaces.

CONFIG Commands

SNMP Notify Type Settings

SNMP Notify Type is supported beginning with Firmware Version 7.4.2.

set snmp notify type [ v1-trap | v2-trap | inform ]

Sets the type of SNMP notiﬁcations that the system will generate:

•

v1-trap

– This selection will generate notiﬁcations containing an SNMPv1 Trap

Protocol

Data Unit

(PDU)

•

v2-trap

– This selection will generate notiﬁcations containing an SNMPv2 Trap PDU

•

inform

– This selection will generate notiﬁcations containing an SNMPv2 InformRe-

quest PDU.

System Settings

You can conﬁgure system settings to assign a name to your Netopia Gateway and to spec-

ify what types of messages you want the diagnostic log to record.

set system name

name

Speciﬁes the name of your Netopia Gateway. Each Netopia Gateway is assigned a name as

part of its factory initialization. The default name for a Netopia Gateway consists of the

word “Netopia-3000/XXX” where “XXX” is the serial number of the device; for example,

Netopia-3000/9437188. A system name can be 1 – 255 characters long. Once you have

assigned a name to your Netopia Gateway, you can enter that name in the

Address

text ﬁeld

of your browser to open a connection to your Netopia Gateway.

☛

NOTE:

Some broadband cable-oriented Service Providers use the

System Name

as

an important identiﬁcation and support parameter. If your Gateway is part of

this type of network, do

NOT

alter the System Name unless speciﬁcally

instructed by your Service Provider.

set system diagnostic-level

{ off | low | medium | high | alerts | failures }

Speciﬁes the types of log messages you want the Netopia Gateway to record. All messages

with a level equal to or greater than the level you specify are recorded. For example, if you

specify set system diagnostic-level

medium

, the diagnostic log will retain medium-level

informational messages, alerts, and failure messages. Specifying

off

turns off logging.

Use the following guidelines:

• low

- Low-level informational messages or greater; includes trivial status messages.

• medium

- Medium-level informational messages or greater; includes status messages

that can help monitor network trafﬁc.

• high

- High-level informational messages or greater; includes status messages that

may be signiﬁcant but do not constitute errors. The default.

• alerts

- Warnings or greater; includes recoverable error conditions and useful opera-

tor information.

• failures

- Failures; includes messages describing error conditions that may not be

recoverable.

set system log-size [ 10240... 65536 ]

Speciﬁes a size for the system log. The most recent entries are posted to the beginning of

the log. When the log becomes full, the oldest entries are dropped. The default is 30000.

set system persistent-log [ off | on ]

When set to

on

, causes the log information to be kept in ﬂash memory.

set system idle-timeout { telnet [ 1...120 ] | http [ 1... 120 ] }

Speciﬁes a timeout period of inactivity for telnet or HTTP access to the Gateway, after

which a user must re-login to the Gateway. Defaults are 5 minutes for HTTP and 15 min-

utes for telnet.

set system username { administrator

name

| user

name

}

Speciﬁes the usernames for the administrative user – the default is

admin

; and a non-

administrative user – the default is

user

.

CONFIG Commands

set system password { admin | user }

Speciﬁes the administrator or user password for a Netopia Gateway. When you enter the

set system password

command, you are prompted to enter the old password (if

any) and new password. You are prompted to repeat the new password to verify that you

entered it correctly the ﬁrst time. To prevent anyone from observing the password you

enter, characters in the old and new passwords are not displayed as you type them. For

security, you cannot use the “step” method to set the system password.

A password can be as many as 8 characters. Passwords are case-sensitive.

Passwords go into effect immediately. You do not have to restart the Netopia Gateway for

the password to take effect. Assigning an administrator or user password to a Netopia

Gateway does not affect communications through the device.

set system heartbeat option { on | off }

protocol [ udp | tcp ]

port-client [ 1 - 65535 ]

ip-server [

ip_address

|

dns_name

]

port-server [ 1 - 65535 ]

url-server ("

server_name

")

number [ 1 – 1073741823 ]

interval (00:00:00:20)

sleep (00:00:30:00)

contact-email ("

string

@

domain_name

")

location ("

string

"):

The heartbeat setting is used in conjunction with the conﬁguration server to broadcast con-

tact and location information about your Gateway. You can specify the

protocol

,

port

,

IP

-,

port

-, and

URL-server

.

•

The

interval

setting speciﬁes the broadcast update frequency. Part of sequence con-

trol. The interval is the spacing between heartbeats, in d:h:m:s.

•

The

contact-email

setting is a quote-enclosed text string giving an email address for

the Gateway’s administrator.

•

The

location

setting is a text string allowing you to specify your geographical or other

location, such as “Secaucus, NJ.”

•

The

number

setting is part of the sequence control. This is the number of heartbeats

to send, at each “interval”, before sleeping. For example, if this is 20, in the above lay-

Rate
