Cisco MGX 8230 Edge Concentrator Installation and Configuration
Release 1.1.31, Part Number 78-11215-03 Rev. B0, May 2001
Chapter6 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).
