display netanalysis rocev2 cache

Use display netanalysis rocev2 cache to display the configuration and status of the RoCEv2 cache.

Syntax

Parameters

destination destination-ip: Specifies a server IP address.

source source-ip: Specifies a client IP address.

Usage guidelines

The device uses the RoCEv2 cache to save RoCEv2 traffic statistics after receiving RoCEv2 flows. When an RoCEv2 flow ages out, the device deletes the related traffic statistics from the RoCEv2 cache.

Examples

# Display the configuration and status of the RoCEv2 cache when bidirectional mode is used for RoCEv2 traffic analysis.

netanalysis rocev2 ai-ecn enable

Use netanalysis rocev2 ai-ecn enable to enable AI ECN for RoCEv2 traffic statistics collection.

Use undo netanalysis rocev2 ai-ecn enable to disable AI ECN for RoCEv2 traffic statistics collection.

Syntax

netanalysis rocev2 ai-ecn enable

undo netanalysis rocev2 ai-ecn enable

Default

AI ECN is disabled for RoCEv2 traffic statistics collection.

Views

System view

Predefined user roles

network-admin

mdc-admin

Usage guidelines

AI ECN allows the device to collect RoCEv2 traffic statistics on a per-session basis on the outgoing interfaces for RoCEv2 traffic and send the RoCEv2 traffic statistics to the NDA. Based on the RoCEv2 traffic statistics, the NDA automatically adjusts the ECN threshold for lossless queues to ensure low latency and high throughput for lossless traffic. For more information about ECN, see QoS configuration in ACL and QoS Configuration Guide.

Examples

# Enable AI ECN for RoCEv2 traffic statistics collection.

<Sysname> system-view

[Sysname] netanalysis rocev2 ai-ecn enable

netanalysis rocev2 drop global

Use netanalysis rocev2 drop global to enable RoCEv2 packet loss analysis globally.

Use undo netanalysis rocev2 drop global to disable RoCEv2 packet loss analysis globally.

Syntax

netanalysis rocev2 drop global

undo netanalysis rocev2 drop global

Default

RoCEv2 packet loss analysis is disabled globally.

Views

Usage guidelines

For RoCEv2 packet loss analysis to take effect, first enable bidirectional mode for RoCEv2 traffic analysis.

This command enables the device to perform RoCEv2 packet loss analysis for all received RoCEv2 packets.

To view RoCEv2 packet loss statistics, examine the S2D NAK Pkts and D2S NAK Pkts fields in the output from the display netanalysis rocev2 cache command.

Examples

# Enable RoCEv2 packet loss analysis globally.

<Sysname> system-view

[Sysname] netanalysis rocev2 drop global

Related commands

netanalysis rocev2 mode

netanalysis rocev2 mode

Use netanalysis rocev2 mode to set the mode of RoCEv2 traffic analysis.

Use undo netanalysis rocev2 mode to restore the default.

Syntax

netanalysis rocev2 mode { bidir | single }

undo netanalysis rocev2 mode

Default

RoCEv2 traffic analysis is disabled, and the mode of RoCEv2 traffic analysis is not set.

Views

System view

Predefined user roles

network-admin

mdc-admin

Parameters

bidir: Specifies bidirectional mode. In this mode, NetAnalysis collects RoCEv2 traffic statistics based on RoCEv2 sessions and provides the RTT and lost packet count for each RoCEv2 session.

single: Specifies unidirectional mode. In this mode, NetAnalysis collects RoCEv2 traffic statistics based on RoCEv2 flows and does not provides the flow-specific RTT or lost packet count.

Usage guidelines

For NetAnalysis features to take effect, first set the mode of RoCEv2 traffic analysis.

When you change the mode of RoCEv2 traffic analysis, all NetAnalysis configuration and the RoCEv2 cache are cleared. Make sure you are fully aware of the impact of this operation when you perform it on a live network.

When multiple paths exist between an RDMA client and an RDMA server, set the mode of RoCEv2 traffic analysis as follows to ensure correct RoCEv2 traffic analysis:

·     Enable bidirectional mode on the devices attached to the server and the client.

·     Enable unidirectional mode on the intermediate devices.

Examples

# Enable unidirectional RoCEv2 traffic analysis.

<Sysname> system-view

[Sysname] netanalysis rocev2 mode single

This operation will erase all the net analysis configuration.

Continue?[Y/N]:y

# Enable bidirectional RoCEv2 traffic analysis.

<Sysname> system-view

[Sysname] netanalysis rocev2 mode bidir

This operation will erase all the net analysis configuration.

Continue?[Y/N]:y

netanalysis rocev2 report-interval

Use netanalysis rocev2 report-interval to set the interval for reporting RoCEv2 traffic statistics to the NDA.

Use undo netanalysis rocev2 report-interval to restore the default.

Syntax

netanalysis rocev2 report-interval interval

undo netanalysis rocev2 report-interval

Default

The device reports RoCEv2 traffic statistics to the NDA at an interval of 10 seconds.

Parameters

seconds: Specifies an interval value in seconds, in the range of 5 to 500.

Usage guidelines

Use this command to adjust the interval at which the device reports RoCEv2 traffic statistics to the NDA.

Examples

# Configure the device to report RoCEv2 traffic statistics to the NDA at an interval of 15 seconds.

<Sysname> system-view

[Sysname] netanalysis rocev2 report-interval 15

netanalysis rocev2 statistics

Use netanalysis rocev2 statistics to enable RoCEv2 traffic statistics collection.

Use undo netanalysis rocev2 statistics to disable RoCEv2 traffic statistics collection.

Syntax

netanalysis rocev2 statistics { global | acl name acl-name }

undo netanalysis rocev2 statistics

Default

RoCEv2 traffic statistics collection is disabled.

Views

System view

Predefined user roles

network-admin

mdc-admin

Parameters

global: Specifies all received RoCEv2 traffic.

acl name acl-name: Specifies an advanced ACL for filtering RoCEv2 traffic by its name, a case-insensitive string of 1 to 63 characters. The ACL name must begin with an uppercase or lowercase letter and cannot be all.

Usage guidelines

Use this command to enable NetAnalysis to analyze RoCEv2 traffic and send the analysis results to the NAP. You can use an ACL to match the RoCEv2 traffic of interest. The deny or permit action in the ACL does not take effect. NetAnalysis supports the following rules of advanced ACLs:

·     Rule 1—Matches the UDP protocol and destination IPv4 address.

·     Rule 2—Matches the UDP protocol and source IPv4 address.

·     Rule 3—Matches the UDP protocol and source and destination IPv4 addresses.

To ensure correct collection and reporting of RoCEv2 traffic statistics, use the rules supported by NetAnalysis. For more information about ACLs, see ACL and QoS Configuration Guide.

If the specified ACL does not exist or does not contain any rules, this command does not take effect.

If a rule in the specified ACL has the vpn-instance criterion configured, the rule applies only to VPN traffic. If a rule does not have the vpn-instance criterion configured, the rule applies to both public network traffic and VPN traffic.

If you execute this command multiple times, the most recent configuration takes effect.

Examples

# Enable NetAnalysis to collect statistics about all received RoCEv2 traffic.

<Sysname> system-view

[Sysname] netanalysis rocev2 statistics global

# Enable NetAnalysis to collect statistics about the received RoCEv2 traffic that matches ACL abc.

<Sysname> system-view

[Sysname] netanalysis rocev2 statistics acl name abc

netanalysis rocev2 timeout inactive

Use netanalysis rocev2 timeout inactive to set the aging timer for inactive RoCEv2 flows.

Use undo netanalysis rocev2 timeout inactive to restore the default.

Syntax

undo netanalysis rocev2 timeout inactive

Default

The aging timer for inactive RoCEv2 flows is set to 30 seconds.

Parameters

seconds: Sets the aging timer for inactive RoCEv2 flows, in seconds. The value range for this argument is 5 to 500 seconds.

Usage guidelines

When an inactive RoCEv2 flow ages out, the device outputs the related traffic statistics to the NDA and deletes these traffic statistics from the RoCEv2 cache.

Examples

# Set the aging timer for inactive RoCEv2 flows to 10 seconds.

<Sysname> system-view

[Sysname] netanalysis rocev2 timeout inactive 10

reset netanalysis rocev2 statistics

Usage guidelines

Use this command to clear RoCEv2 traffic statistics if you want to collect RoCEv2 traffic statistics for a specific time period.

You cannot recover cleared RoCEv2 traffic statistics. Make sure you are fully aware of the impact of this command when you use it on a live network.

Examples
