Bit Error Rate Testing Through an MGX-SRM-3T3

The MGX 8850 bus structure supports one BERT session per upper or lower bay, so the switch can run a maximum of two sessions at once. When you specify the target slot through the CiscoView application or the CLI, the system determines if a BERT configuration already exists in that bay. After the system determines that no BERT configuration exists in the applicable bay, the display presents a menu for the BERT parameters.

The CLI commands (whose functions correspond to CiscoView selections) are:

•

•

•

•

cnfbert to configure and start a test

modbert to inject errors into the BERT bit stream

dspbert to display the parameters and results of the current test

delbert to end the current test

Note When a BERT session begins, all connections on a line or port go into alarm and return to normal when the test ends. Consequently, the test may result in other types of traffic (such as AIS).

During configuration, the displayed parameters or menu items depend first on the card type and whether the test medium is a physical line or a logical port. Subsequent choices are test type, test patterns, loopback type, and so on. See the Cisco MGX 8850 Wide Area Edge Switch Command Reference for details on cnfbert and the other BERT commands. The concatenation of menu to menu is extensive, so this section contains tables of menu selections based on the card types and the test type.

The test type can be pattern, loopback, or DDS seek. The choice of test type leads to further menu displays. Following the tables of menu choices, the remaining sections define the parameters in these menu choices.

•For AX-FRSM-8T1, MGX-CESM-8T1, and MGX-FRSM-2CT3, see Table 6-5pattern tests and Table 6-6for loopback tests.

•For AX-FRSM-8E1 and MGX-CESM-8E1, see Table 6-7for pattern tests and Table 6-8for loopback tests.
