Port monitor commands

port

Syntax

port port-id [port-id...(up to 5 max)] [interval seconds] [repeat repeat] [absolute | rate] [multiclass]

Context

monitor

Platforms

Supported on all 7210 SAS platforms as described in this document, including platforms configured in the access-uplink operating mode

Description

This command enables port traffic monitoring. The specified ports statistical information displays at the configured interval until the configured count is reached.

The first screen displays the current statistics related to the specified ports. The subsequent statistical information listed for each interval is displayed as a delta to the previous display.

When the keyword rate is specified, the rate per second for each statistic is displayed instead of the delta.

Monitor commands are similar to show commands but only statistical information displays. Monitor commands display the selected statistics according to the configured number of times at the interval specified.

Parameters

port port-id

Specifies up to 5 port IDs in slot/mda/port format.

interval seconds

Specifies the interval for each display in seconds.

Values

3 to 60

Default

10

repeat repeat

Specifies how many times the command is repeated.

Values

1 to 999

Default

10

absolute

Displays the raw statistics are displayed, without processing. No calculations are performed on the delta or rate statistics.

rate

Displays the rate-per-second for each statistic instead of the delta.

Output

The following output is an example of port traffic monitoring information.
