Performance Monitor Configuration

Performance Monitoring (PM) is a Carrier Ethernet software feature that collects, stores, and transfersstatistics from the Operations, Administration and Management (OAM) engine according to a user'sconfiguration. These statistics relate to delay, loss, Ethernet Virtual Connections (EVC), EVC ControlEntry (ECE), and more. The user can select which data to collect as well as the intervals for collectionand transfer.

This document provides examples of how to setup the Performance Monitor feature with Microsemi’sIndustrial Command Line Interface (ICLI). It also includes the command set and their meanings.

Examples used in this document are specific to the VSC7418, but the software works similarly for otherdevices as well.

Configuration OptionsThis section describes the available configuration options.

Session, Storage, and Transfer ConfigurationUp-MEP support is required for configuring the performance monitors. Add mep_loop_port to thefollowing line in the configuration file (config.mk) to enable the VTSS_SW_OPTION_MEP_LOOP_PORToption in the source code.

Custom/AddModules := mep_loop_portThe device must be configured for EVC and ECE before gathering performance monitor information.

Scheduled Offset Specify a fixed offset to be added to the scheduled transfer time.The default is 0 minutes. The range is between 0 and 15 minutes.

Note: The sum of scheduled fixed offset and scheduled randomoffset must not exceed 15 minutes.

Random Offset Specify a random offset to be added to the scheduled transfer time.The default is 0 seconds. The range is between 0 to 900 seconds.

The offset added to the scheduled transfer time is a random valuein the range of 0 seconds to random offset.

Note: The sum of scheduled fixed offset and scheduled randomoffset must not exceed 15 minutes.

Server Directory URL The full URL of the server and the corresponding directory (if setproperly) for uploading.

HTTP and TFTP are supported.

To enable HTTP, use http://<domain name or IP address>

To enable TFTP, use tftp://<domain name or IP address>

Transfer Interval Mode Supported interval modes:

• All available intervals: To enable transfer of all completedmeasurement Intervals.

• New intervals since last transfer: To enable transfer of onlycompleted measurement Intervals since last transfer.

• Fixed number of intervals: To enable transfer of allcompleted measurement Intervals up to the configurednumber.

Number of intervals Specify the number of intervals to send when fixed number ofinterval is selected. The range is between 1 and 96 Intervals.

Transfer Option Select this option to include intervals from previous incompletetransfers.

Note: All measurement intervals are displayed if a measurement interval ID is not selected. The volume ofmeasurement data to be displayed can make this a very time consuming process.

ICLI Show CommandsShow commands are available under exec mode. Outside of the exec mode, the commands may beinvoked by the do show <show commands> command.

Show perf-mon current featureUse the following syntax to display the current performance monitor measurement data for a specifiedfeature.

show perf-mon current feature { dm | lm | evc }In the following example, 237 is the current Interval ID.

# show perf-mon current feature evc Interval ID : 237--------------------------------------------------------

Show perf-mon interval-id ID featureUse the following syntax to display the specified current performance monitor measurement data for aspecific interval and feature.

show perf-mon interval-id ID feature { dm | lm | evc }where ID is the integer value of the specified interval. For example, if 144 is the interval ID to be queried,it can be used as follows:

# show perf-mon interval-id 144 feature evc Interval ID : 144--------------------------------------------------------

EVC instance = 10 EVC port= 1Valid= yesTx green frames= 832Tx green bytes= 831020 Tx yellow frames= 0Tx yellow bytes= 0 Tx red frames= 0Tx red bytes= 0 Tx discard frames = 0Tx discard bytes= 0 Rx green frames= 533Rx green bytes= 501324Rx yellow frames= 0Rx yellow bytes= 0 Rx red frames= 0Rx red bytes = 0 Rx discard frames = 0 Rx discard bytes = 0

Show perf-mon interval-info featureUse the following syntax to show the list of performance monitor intervals of a specific feature.

show perf-mon interval-info feature { dm | lm | evc }When querying past measurement information a measurement ID needs to be queried first, as shown inthe following example.

# show perf-mon interval-info feature eve EVC Interval Information--------------------------------------------------------Measurement interval ID = 143Start time= 1970-01-01T02:01:25+00:00End time= 1970-01-01T02:02:25+00:00End time= 60 seconds Measurement interval ID = 144Start time= 1970-01-01T02:02:25+00:00End time= 1970-01-01T02:03:25+00:00End time= 60 seconds Measurement interval ID = 145Start time= 1970-01-01T02:03:25+00:00End time= 1970-01-01T02:04:25+00:00End time= 60 seconds…

where URL can be in the following form.

tftp://<ip address>/

http://<domain name>/

tftp://<ip address>/

http://<domain name>/

Enable the inclusion of previous incomplete transfers with the currentinterval transfer.

perf-mon transfer incomplete

Disable the inclusion of previous incomplete transfers with the currentinterval transfer.

no perf-mon transfer incomplete

Specify a transfer time. This command can be specified multiple times tospecify the different hours of a day. Transfer time is comprised of thefollowing commands.

perf-mon transfer hour <0-23>

perf-mon transfer minute { 0 | 15 | 30 | 45 }

perf-mon transfer fixed-offset <0-15>

perf-mon transfer random-offset <0-900>

The minute command can be specified multiple times to specify the differentminutes of an hour. If data is to be transferred four times per hour, set all ofthem. The fixed-offset is a single offset setting that is added to transfer hourand minute to allow a range between 0 and 15 minutes.

The random time offset is added to the previous time configurations andaccepts a value between 0 and 900 seconds. This is useful when allswitches are time synchronized and configuration is copied across allswitches. This avoids all switches uploading data at the same moment,which may overload the TFTP or HTTP server.

Each of the transfer time commands support a negate feature.

no perf-mon transfer hour no perf-mon transfer hour x no perf-mon transfer minute no perf-mon transfer minute x no perf-mon transfer fixed-offset no perf-mon transfer random-offsetCommands with parameters remove the indicated parameter only. If noparameter is provided, all settings for the command are removed.
