Network and device
management

A full console interface, accessible
using either a Telnet interface or the
serial port (VT-100 or VT-100 emulator)
on the front panel, can be used to
configure and monitor the IBM 8270.
Alternatively, the IBM 8270 contains a
management agent that allows you to
monitor and control its operation from
SNMP applications. IBM’s suite of
network management applications,
such as the IBM Nways Workgroup
Manager for Windows NT

®

 and the IBM

Nways Manager for AIX

®

, allow you to

manage your IBM 8270 using a rich set
of graphical interfaces from a central
location.

Further, when and if new functions or
problem fixes become available, the
IBM 8270 can be easily upgraded with
new operational code.  These software
updates will be made available via the
World Wide Web, allowing you to
conveniently upgrade the operation
of your IBM 8270.

With the IBM 8270’s TokenProbe
support, you can designate one of
the Token-Ring ports to mirror the traffic
on another Token-Ring port. This allows
you to tune or troubleshoot any of the
Token-Ring ports on your switch using
an external protocol analyzer.  The IBM
8270 SNMP agent also includes
remote monitoring (RMON) support
that allows you to monitor network
conditions on all LAN segments
attached to your 8270 simultaneously
and to report this information to an
RMON application using industry-
standard protocols.
