their respective values depending on your specific needs. Modifications though can only
be performed on MIB objects with read-write or write-only attributes. To access MIB-II
objects from an SNMP device, perform these steps:

1.

Select the corresponding icon of the device from the map.

2.

From the General menu, choose

MIB II

.

Information

Choosing this command displays the MIB-II Information dialog box:

The following describes each MIB object:

SysDescr

is a read-only MIB object of the system group that provides textual

description of the device. These include the name and version identification of the
device hardware, software operating system, and networking software.

SysOID

is a read-only MIB object of the system group that specifies the corresponding

enterprise ID of the device.

SysUpTime

is a read-only MIB object of the system group that displays the time since

the network management portion of the device was last re-initialized.

SysName

is a read-write MIB object of the system group that allows you to specify a

name for the device. By convention, this will be the device domain name. For
information on how to set this object, see the discussion below.

SysLocation

is a read-write MIB object of the system group that allows you to specify

the actual location of the device. For information on how to set this object, see the
discussion below.

SysContact

is a read-write MIB object of the system group that allows you to specify

the person to contact in case problems are encountered in the device. For information
on how to set this object, see the discussion below.

Network Interfaces

correspond to the IfNumber MIB object of the interface group. This

read-only object displays the total number of interfaces (regardless of their current
states) available on the device.
First

NI PhysAddress

corresponds to the IfPhysAddress MIB object of the interface

group. This read-only object displays the MAC address of the device interface at the
protocol layer immediately below the network layer in the protocol stack. Hubs usually
have one interface, whereas routers have more than one.

Forwarding State

corresponds to the IpForwarding MIB object of the ip group. This

read-write object indicates whether or not the device is acting as an IP gateway in
