The management processor module (

MPX

 on the Omni Switch/Router) coordinates control of 

the Omni Switch/Router by providing access to the User Interface (

UI

) software, maintaining 

user configuration information, downloading switching module software, managing basic 
bridge functions, maintaining basic routing functions, and managing the 

SNMP

 management 

agent. Switching modules are dependent on the 

MPX

 for downloading software and for 

receiving initialization and configuration information. In addition, the Network Management 
System (

NMS

) depends on the 

MPX

 to send and receive 

SNMP

 messages for managing the 

switch.

♦ Important Note ♦

All of the 

UI

 commands described in this chapter also 

work with the Omni Switch/Router 

MPX

.

The Omni Switch/Router also support two 

MPXs

 with one acting as the primary and with one 

acting as the secondary. If the primary 

MPX

 fails, the secondary 

MPX

 can take over automati-

cally. Operating with redundant 

MPXs

 can also help avoid network downtime.

♦ Note ♦

When you have two 

MPX

s in one chassis, they must be 

installed in slots 1 and 2, and only one will be active.

The primary 

MPX

 executes all the commands and, when needed, sends requests to the 

secondary 

MPX

. The secondary 

MPX

 continuously monitors the primary 

MPX

. For more infor-

mation on 

MPXs

, see Chapter 2, “The Omni Switch/Router 

MPX

.”

The 

UI

 provides commands to configure the serial port, to configure the Ethernet manage-

ment port, and a set of commands to monitor and configure primary and secondary 

MPXs

. 

These commands are described in the pages that follow.
