Chapter 6 Card and Service Configuration

Configuring Frame Relay Service

tstcon checks the integrity of a connection.

tstdelay measures the round-trip delay on a connection.

cnftrafficgen enables/disables traffic-generation tests on a per LCN basis. Use the dsptrafficgen command to display the traffic-generation test results.

Support for Alarm Reporting

The FRSM cards support card and line-level alarm reporting. Use the CiscoView application or the CLI to view current alarms. The CLI commands are dspalmcnt, dspalm, and dspalms. These commands require a switch, either “-x21 or “-hs1” whichever is valid, to identify the interface type. See the MGX 8800 Series Command Reference for syntax and alarm descriptions.

Bit Error Rate Testing on an Unchannelized T3 or E3 FRSM

The MGX 8230 shelf can perform a bit error rate test (BERT) on one active line at a time on the MGX-FRSM-2T3E3. This type of testing disrupts service because it requires the tested path to be in loopback mode. You can configure a BERT session and perform related tasks through the CiscoView application or the CLI.

The MGX 8230 bus structure supports one BERT session per upper or lower bay of the card cage, so the shelf can run a maximum of two sessions at once. When you specify the target slot through the CiscoView application or the acqdsx3bert command on the CLI, the system determines if a BERT configuration already exists in the bay that has the specified slot. If no BERT configuration exists in the bay, the display presents a menu for the BERT parameters.

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

acqdsx3bert to determine if other BERT sessions exist in the bay

cnfdsx3bert to specify a pattern for the BERT test

startdsx3bert to start a BERT test (after resetting BERT counters)

moddsx3bert to inject multi-rate errors into the BERT bit stream

dspdsx3bert to display the parameters and results of the current test

deldsx3bert to end the current test (and retain the values in the BERT counters)

See the Cisco MGX 8230 Wide Area Edge Switch Command Reference for command details.

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