Repeater Redundancy

from the command line (stand-alone mode):

1.From the appropriate directory, type:

spmarun r4red <IP address> <community name>

NOTES

The spmarun script invoked Þrst in the above command temporarily sets the environment variables SPMA needs to operate; be sure to use this command any time you launch an application from the command line. The script is automatically invoked when you launch the application from the icon menu or from within the Hub View.

If you wish to change any redundancy settings, be sure to use a community name with at least Read/Write access. If you only wish to view current settings, a community name with Read access will be sufÞcient.

If there is a hostname mapped to your SEHI100TXÕs IP address, you can use <hostname> in place of <IP address> to launch this application. Please note, however, that the hostname is not the same as the device name which can be assigned via Local Management and/or SPMA; you cannot use the device name in place of the IP address.
