Predefined user roles

network-admin

Parameters

number: Specifies the maximum number of keepalive packets in the range of 1 to 100.

Usage guidelines

Use this feature in subway applications to achieve fast link switchover.

With the keepalive packet limit set, an onboard MP sends probe requests to a trackside MP at intervals of 100 milliseconds. If the onboard MP fails to receive a reply when the limit is reached, it terminates the active link or switches to the standby link if a standby link is available.

Make sure the value of the limit multiplied by 0.1 is smaller than the value of the keepalive interval multiplied by 3.

This feature takes effect only when MLSP is enabled.

Examples

# Set the mesh link keepalive packet limit to 10 for mesh policy 1.

<Sysname> system-view

[Sysname] wlan mesh-policy abc

[Sysname-wlan-mesh-policy-abc] active-link keepalive-count 10

Predefined user roles

network-admin

Parameters

threshold-value: Specifies the mesh link establishment threshold in the range of 1 to 100.

Usage guidelines

An onboard MP establishes a mesh link with a trackside MP only when the link RSSI reaches or exceeds the sum of the link establishment threshold and link hold RSSI. This prevents link flapping caused by frequent mesh link establishment.

By fine adjustment of the link establishment threshold, you can control mesh link establishment without changing the link hold RSSI.

Examples

# Set the mesh link establishment threshold to 3 for mesh policy abc.

<Sysname> system-view

[Sysname] wlan mesh-policy abc

[Sysname-wlan-mesh-policy-abc] link-establish-threshold 3

Related commands

Use undo link-hold-time to restore the default.

Syntax

link-hold-time value

undo link-hold-time

Default

The mesh link hold time is 4000 milliseconds.

Views

Mesh policy view

Predefined user roles

network-admin

Parameters

value: Specifies a time value in the range of 1000 to 20000 milliseconds.

Usage guidelines

A link hold timer prevents frequent active link changes to ensure transmission stability in subway mesh networks.

An onboard MP switches to the optimal standby link as long as the link hold timer expires.

If the link hold timer does not expire, an onboard MP switches to the optimal standby link only when either of the following conditions is met:

·     The active link's RSSI exceeds the link saturation RSSI.

·     The active link's RSSI is lower than the link hold RSSI.

If no standby link is available, an MP keeps using the active link when the RSSI on the active link is lower than the link hold RSSI. The MP terminates the active link when the active link RSSI reaches or exceeds the link saturation RSSI.

This feature takes effect only when MLSP is enabled.

Examples

# Set the link hold time to 5000 milliseconds for mesh policy abc.

<Sysname> system-view

[Sysname] wlan mesh-policy abc

[Sysname-wlan-mesh-policy-abc] link-hold-time 5000

Related commands

Views

Mesh policy view

Predefined user roles

network-admin

Usage guidelines

Mesh link initiation enables the MP to send Link Open requests to a peer without having received a Link Open request from that peer. If this feature is disabled, the MP must wait for a Link Open request from its peer before it can send one.

Examples

# Disable mesh link initiation.

<Sysname> system-view

[Sysname] wlan mesh-policy abc

[Sysname-wlan-mesh-policy-abc] undo link-initiation enable

Related commands

link-keepalive

Use link-keepalive to set the mesh link keepalive interval.

Use undo link-keepalive to restore the default.

Syntax

link-keepalive keepalive-interval

undo link-keepalive

Default

The mesh link keepalive interval is 2 seconds.

Views

Mesh profile view

Predefined user roles

network-admin

Parameters

keepalive-interval: Specifies a keepalive interval in the range of 1 to 1800 seconds.

Usage guidelines

MPs on a mesh link use keepalive packets to detect mesh link status. The MP with a higher MAC address sends keepalive packets at the keepalive interval to the peer end. The sending MP disconnects the mesh link if it has not received a reply before three consecutive keepalive intervals expire. The receiving MP disconnects the mesh link if it has not received keepalive packets before three consecutive keepalive intervals expire. For correct link status detection, the keepalive interval at the sending end must be equal to or less than three times the keepalive interval at the receiving end.

Examples

# Set the mesh link keepalive interval to 6 seconds in mesh profile 1.

<Sysname> system-view

[Sysname] wlan mesh-profile 1

[Sysname-wlan-mesh-profile-1] link-keepalive 6

Related commands

display wlan mesh-profile

link-maximum-number

Use link-maximum-number to set the maximum number of mesh links on a radio.

Use undo link-maximum-number to restore the default.

Syntax

link-maximum-number max-link-number

undo link-maximum-number

Default

A maximum of two mesh links can be established on a radio.

Views

Mesh policy view

Predefined user roles

network-admin

Parameters

max-link-number: Specifies a limit in the range of 1 to 8.

Usage guidelines

The MP will stop establishing new mesh links on a radio after the maximum number of mesh links is reached.

Examples

# Set the maximum number of mesh links to 5 for mesh policy abc.

<Sysname> system-view

[Sysname] wlan mesh-policy abc

[Sysname-wlan-mesh-policy-abc] link-maximum-number 5

Related commands

display wlan mesh-policy

link-optimize-threshold

Use link-optimize-threshold to set the threshold for MLSP link switchover optimization.

Use undo link-optimize-threshold to restore the default.

Syntax

link-optimize-threshold threshold-value

undo link-optimize-threshold

Default

The MLSP link optimization threshold is 30.

Views

Mesh policy view

Predefined user roles

network-admin

Parameters

threshold-value: Specifies the MLSP link optimization threshold in the range of 15 to 80.

Usage guidelines

With MLSP link switchover optimization enabled, the system switches to the optimal mesh link if the RSSIs of secure standby links reach the threshold. A secure standby link is a link that has never been replaced by link switchover optimization.

Perform multiple on-site tests and set the threshold to a proper value based on the test results. If the threshold is too high, the device might fail to switch its mesh link in time, causing packet loss. If the threshold is two low, the mesh link in use might have a low RSSI, affecting traffic transmission.

Examples

# Set the threshold for MLSP link switchover to 45.

<Sysname> system-view

[Sysname] wlan mesh-policy abc

[Sysname-wlan-mesh-policy-abc] link-optimize-threshold 45

Related commands

display wlan mesh-policy

mlsp-optimize enable

link-saturation-rssi

Use link-saturation-rssi to set the link saturation RSSI.

Use undo link-saturation-rssi to restore the default.

Syntax

link-saturation-rssi value

Views

Mesh policy view

Predefined user roles

network-admin

Parameters

value: Specifies a link saturation RSSI value in the range of 30 to 150.

Usage guidelines

To prevent strong signal strength from affecting chip performance, an MP terminates the active link when the link's RSSI exceeds the link saturation RSSI. If MLSP is enabled, the onboard MP will try to establish an active mesh link with another mesh peer.

Examples

# Set the link saturation RSSI to 50 for mesh policy abc.

<Sysname> system-view

[Sysname] wlan mesh-policy abc

[Sysname-wlan-mesh-policy-abc] link-saturation-rssi 50

Predefined user roles

network-admin

Usage guidelines

In subway applications, RSSIs on onboard MPs might be greatly larger than RSSIs on trackside MPs when the train passes the trackside MPs and the MPs' antennas point to the same direction. This might cause loss of packets from onboard MPs to trackside MPs. Mesh link switchover optimization enables onboard MPs to switch to the optimal standby links in advance to avoid packet loss.

With this feature enabled, an onboard MP switches to the optimal secure standby link whose RSSI exceeds the optimization threshold after the link hold time is reached. A secure standby link is a link that has never been replaced by MLSP link switchover optimization. If an active link is replaced by MLSP link switchover optimization, the link is marked as unsecure.

This feature takes effect only when MLSP is enabled.

To use this feature, you must perform on-site tests. If packet loss does not occur during the tests, do not configure this feature as a best practice.

Examples

# Enable MLSP link switchover optimization.

all: Specifies all proxied devices.

Usage guidelines

This feature enables an onboard MP to use the MAC address of the proxied device to send gratuitous ARP packets for MAC address table update of trackside MPs. This ensures fast transmission of downlink packets over the new active link after a link switchover.

To specify multiple proxied devices, repeat this command.

Disabling MLSP clears all MLSP proxy settings.

This command is unavailable when MLSP is disabled.

Examples

# Configure onboard MPs to proxy the device with MAC address 000f-e201-0101.

<Sysname> system-view

[Sysname] wlan mesh-policy abc

[Sysname-wlan-mesh-policy-abc] mlsp enable

[Sysname-wlan-mesh-policy-abc] mlsp-proxy mac-address 000f-e201-0101 vlan 1

preshared-key

Use preshared-key to add a preshared key to a mesh profile.

Use undo preshared-key to restore the default.

Syntax

preshared-key { pass-phrase | raw-key } { cipher | simple } string

undo preshared-key

Default

A mesh profile does not contain a preshared key.

Views

Mesh profile view

Predefined user roles

network-admin

Parameters

pass-phrase: Sets the key in character string form.

raw-key: Sets the key in hexadecimal form.

cipher: Specifies the key in encrypted form.

simple: Specifies the key in plaintext form. For security purposes, the key specified in plaintext form will be stored in encrypted form.

string: Specifies a case-sensitive key string. The following are the key length ranges:

·     pass-phrase plaintext—8 to 63 characters.

·     pass-phrase ciphertext—41 to 117 characters.

·     raw-key plaintext—64 hexadecimal digits.

·     raw-key ciphertext—117 characters.

Usage guidelines

Make sure the mesh profile is disabled before you use this command.

You can configure only one preshared key in a mesh profile. If you execute this command multiple times, the most recent configuration takes effect.

Examples

# Add preshared key abcdefghig in plain text to mesh profile 1.

<Sysname> system-view

[Sysname] wlan mesh-profile 1

[Sysname-wlan-mesh-profile-1] preshared-key pass-phrase simple abcdefghig

Predefined user roles

network-admin

Usage guidelines

To avoid mesh connection failures caused by waveguide link switchover, enable fast waveguide link switchover for the mesh policies bound to both onboard and trackside MPs.

With this feature enabled, an onboard MP switches to a waveguide link once the MP detects the link.

Examples

# Enable fast waveguide link switchover.

<Sysname> system-view

[Sysname] wlan mesh-policy abc

[Sysname-wlan-mesh-policy-abc] waveguide fast-switch enable

Predefined user roles

network-admin

Parameters

value: Specifies the waveguide link hold RSSI in the range of 5 to 100.

Usage guidelines

If the RSSI of the waveguide active link drops below the waveguide link hold RSSI, the MP switches to the optimal waveguide link or terminates the active link.

Examples

# Set the waveguide link hold RSSI to 24.

<Sysname> system-view

[Sysname] wlan mesh-policy abc

[Sysname-wlan-mesh-policy-abc] waveguide-hold-rssi 24
