Figure 14. Management Schematic
The DMM (and daughter cards) provide management and control facilities in the
following areas:
− Configuration
The DMM, networks, modules, and port settings can be configured
through the DMM using DMM commands. The DMM can be used to
configure 8250 as well as 8260 modules.
− Statistics and fault reporting
E-MAC and T-MAC provide support for collecting an extensive range of
statistics based on RMON.
− Out-of-band and in-band downloading
The DMM provides both in-band and out-of-band download features for
downloading new software to DMM, media modules, and daughter cards.
Trivial File Transfer Protocol (TFTP) is used for in-band downloads.
Out-of-band downloads allow you to download software using the
Xmodem protocol from a local or modem attached PC (with ASCII
emulation software) attached to the RS-232 port on the front panel of the
DMM.
− SNMP support
