Mrm Resilience Application

This application provides access to the Mrm Resilience Table view. The model for this application is 3CommrmResApp.

Mrm Resilience View

This view contains the Mrm Resilience Table and the following:

Flush Table

Setting this menu button to Flush empties the Resilience Table. Once flushed, no resilient links are configured. You can now configure new links.

Add Entry

This button opens the Add Resilient Table Entry view. Enter the Instance of the new pair and set the Under Mod field to Under-Mod. This creates an empty entry in the table. Double-click the entry to be able to enter the definition.

StandBy Map Table

This button opens the Mrm Resilience Standby Table.

Mrm Resilience Table

A device can be configured to have a number of “resilient pairs” 802.3 Point-to- Point connections; for example, UTP, which allows two repeaters to be connected in a resilient configuration. In such a pair, one port is the main port, the other the standby port. One of these ports is enabled and is the current active port, the other is present in case the active port fails. The device detects a failure and switches ports.

For a resilient pair definition to be valid, both ports must be on the same repeater. Also, the standby port must be configured to be “disabled on boot”; that is, it must recover from a power failure in a disabled state to prevent loops in the network.

This table allows creation and deletion or resilient pairs and provides status control and information. The entries are indexed on the repeater number and slot/port location of the main port.

Double-clicking an entry accesses the Mrm Resilience Table Entry View in which you can update the configuration of a resilient pair.

Repeater

Displays the repeater on which both ports in the pair are located.
