Remote Management Setup

The switch sends out SNMP traps to network management stations whenever
certain exceptional events occur, such as when the switch is turned on or when a
system reset occurs. The switch enables traps to be routed to up to four different
network management hosts.
For a detailed list of the trap types that are used for this switch, see "Traps" on
page 20.
SNMP (version 1) implements a rudimentary form of security by requiring that each
request include a community name. A community name is an arbitrary string of
characters used as a "password" to control access to the switch. If the switch
receives a request with a community name that it does not recognize, it will trigger
an authentication trap.

turned on. The DCHP protocol enables IP addresses, network masks, and
default gateways to be assigned by a DCHP server. If this option is set, the
switch will first look for a DCHP server to provide it with this information
before using the default or previously entered settings.
This option enables the entry of an IP address, subnet mask, and a default
gateway for the switch. These entries should be of the form xxx.xxx.xxx.xxx,
where each xxx is a number (represented in decimal form) between 0 and
255. This address should be a unique address on the network assigned for
use by the network administrator. The fields that require entries under this
option are as follows:
Subnet Mask
A bitmask that determines the extent of the subnet that the switch
module is on. It should be of the form xxx.xxx.xxx.xxx, where each
xxx is a number (represented in decimal) between 0 and 255. The
value should be 255.0.0.0 for a class A network, 255.255.0.0 for a
class B network, and 255.255.255.0 for a class C network, but
custom subnet masks are permitted.
Note: For switch communication with a remote management
station, such as the IBM Director server, through the
management module external Ethernet port, the switch
module internal network interface and the management
module internal and external interfaces must be on the same
subnet.
Default Gateway
An IP address that determines where packets with a destination
address outside the current subnet should be sent. This is usually
the address of a router or a host acting as an IP gateway. If your
network is not part of an intranet, or if you do not want the device
to be accessible outside your local network, you can enter a value
of 0.0.0.0 in this field.
