The Port Common Configuration of display traffic

Function Description

This topic describes the commands related to the non xDSL and non xPON port configuration and query.

Function

This command is used to query the real-time data transmitting/receiving rate of the port, that is the transmitting/receiving traffic. When you need to query the receiving traffic, transmitting traffic, and traffic index table of a port, run this command.

Format

display traffic frameid/slotid/portid [ channel channelid ]

Parameters

Parameter Description Value
frameid/slotid/portid Indicates the subrack ID, slot ID, and port ID. Enter "/" between the subrack, slot and port IDs. Please see Differences Between Shelves.
channel channelid Indicates the channel number. When you need to query the real-time data transmitting/receiving rate of the specified port, use this parameter. Currently, only VDSL supports it. Numeral type. Range: 1-2.

Modes

Privilege mode, ADEE, ADLE

Level

Operator level

Usage Guidelines

The command is supported only by the ADSL, VDSL, SHDSL, AIUG, OPFA and OPGD boards.

Prewarning for High Memory Usage of the MA5600T

[Fault Description]
Trigger conditions:
The N2510 periodically measures MA5600T performance.

Symptom:
The MA5600T is of high memory usage. The result queried by running the display mem f/s command shows that the memory usage of the active control board is much higher than that of the standby control board.

Identification method:
1. After a period of time, such as 24 hours or 48 hours, run the display mem 0/9 command to query the memory usage of the control board. It is found that the memory usage increases.
2. Compare the memory usage of the active control board with that of the standby control board to determine whether the memory usage of the active control board is high.

[Root Cause]
The N2510 periodically obtains the data of the xDSL line profile. When the N2510 obtains the data of the VDSL mode profile (vdsl2LineConfProfModeSpecTable), the MA5600T encounters a performance-related problem. As a result, the memory usage of the active control board decreases and cannot recover in time.

[Impact and Risk]
After a long period of time, the memory of the active control board is exhausted and the OLT cannot be managed by the NMS.

[Measures and Solutions]
Recovery measures:
If the memory usage of the control board is higher than 85%, run the following command to perform active/standby switchover to transfer services from the active control board to the standby board.
MA5600T(config)#system switch-over

Preventive measures:
This issue will be resolved in MA5600T V800R007C00SPC310(2010-12-10) and later versions.

[Rectification Scope and Time Requirements]
None

[Notice Expiration]
This notice automatically expires in versions later than MA5600T V800R007C00SPC310.
