Configuring a WDS Profile
Context
A WDS profile contains major parameters required for configuring the WDS function. To enable radios of an AP group or a specified AP to set up Mesh links, a WDS profile must be applied to the radios.
Procedure
- Run system-view
The system view is displayed.
- Run wlan
The WLAN view is displayed.
- Run wds-profile name profile-name
A WDS profile is created and the WDS profile view is displayed.
By default, the system provides the WDS profile default.
- Run wds-name name
A WDS name is set for the WDS profile. WDS nodes use a WDS name to identify connections between them.
By default, the WDS name of a WDS profile is HUAWEI-WLAN-WDS.
- Run wds-mode { root | middle | leaf }
The WDS mode is configured in the WDS profile.
By default, the WDS mode in a WDS profile is leaf.
- Run security-profile profile-name
A security profile is bound to the WDS profile.
By default, the security profile default-wds is bound to a WDS profile.
By default, the system provides the WDS profile default. By default, the security profile default-wds with the security policy WPA2+PSK+AES and the security key huawei_secwds is referenced by a WDS profile regardless of whether the WDS profile is the default profile provided by the system or a WDS profile created by users. If the default security profile default-wds is used, you are advised to change the security key of the profile to ensure security.
- Run vlan tagged { vlan-id1 [ to vlan-id2 ] } &<1-10>
A VLAN or a group of VLANs are added to the WDS profile in tagged mode.
By default, no VLAN is configured in a WDS profile.
When configuring WDS, perform this step to configure service VLANs in the WDS profile so that packets from the service VLANs can be transmitted over WDS links.
A maximum of 256 VLANs can be added to a WDS profile.
- (Optional) Improve channel usage efficiency.
Run the beacon-2g-rate beacon-2g-rate command to set the transmit rate of 2.4 GHz Beacon frames.
By default, the transmit rate of 2.4 GHz Beacon frames is 1 Mbit/s.
Run the beacon-5g-rate beacon-5g-rate command to set the transmit rate of 5 GHz Beacon frames.
By default, the transmit rate of 5 GHz Beacon frames is 6 Mbit/s.
- (Optional) Run mu-mimo enable
MU-MIMO is enabled.
By default, the MU-MIMO function is enabled.
APs support MU-MIMO starting from 802.11ac Wave 2. If WDS VAPs need to support MU-MIMO, a WDS profile must be bound to 5 GHz radios of the AP.
In WDS scenarios, ensure that the number of spatial streams on STA VAPs is smaller than that on AP VAPs. Otherwise, MU-MIMO cannot take effect. For example, if STA VAPs and AP VAPs are both configured with three spatial streams, an AP VAP can communicate with only one STA VAP even if MU-MIMO has been enabled.
- (Optional) Run dhcp trust port
A DHCP trusted port is configured in the WDS profile.
By default, no DHCP trusted port is configured in a WDS profile.
After a DHCP trusted port is enabled in a WDS profile and the WDS profile is applied to an AP, the AP receives the DHCP OFFER, ACK, and NAK packets sent by authorized DHCP servers and forwards the packets to STAs so that the STAs can obtain valid IP addresses and go online.
- (Optional) Run nd trust port
An ND trusted port is configured in the WDS profile.
By default, an ND trusted port is enabled in a WDS profile.
After an ND trusted port is enabled in a WDS profile and the WDS profile is applied to an AP, the AP receives valid ND protocol packets and forwards the packets to STAs or peer APs so that the STAs can obtain valid IPv6 addresses and go online.
- (Optional) Run priority-map trust { dot1p | dscp }
The priority mapping trusted by the WDS air interface is configured.
By default, the WDS air interface trusts the mapping from DSCP priorities to 802.11e user priorities.
- (Optional) Run priority-map dscp { dscp-value1 [ to dscp-value2 ] } &<1-10> dot11e dot11e-value
The WDS air interface to be configured to trust the mapping from DSCP priorities to 802.11e user priorities.
Table 1 describes the mapping from DSCP priorities to 802.11e user priorities by default. - Run quit
Return to the WLAN view.
- Apply the WDS profile. You can use any of the following methods according to actual situations:
Bind the WDS profile to an AP group.
Run the ap-group name group-name command to enter the AP group view.
Run the wds-profile profile-name radio { all | radio-id } command to bind the WDS profile to the AP group.
By default, no WDS profile is bound to an AP group or AP.
A WDS link uses the VAPs with the WLAN ID 13 and ID 14, which cannot be occupied by other WLAN services.
Bind the WDS profile to an AP.
- Run the ap-id ap-id, ap-mac ap-mac, or ap-name ap-name command to enter the AP view.
Run the wds-profile profile-name radio { all | radio-id } command to bind the WDS profile to the AP.
By default, no WDS profile is bound to an AP group or AP.
A WDS link uses the VAPs with the WLAN ID 13 and ID 14, which cannot be occupied by other WLAN services.
Bind the WDS profile to AP group radios.
- Run the ap-group name group-name command to enter the AP group view.
- Run the radio radio-id command to enter the radio view.
Run the wds-profile profile-name command to bind the WDS profile to AP group radios.
By default, no WDS profile is bound to an AP radio.
A WDS link uses the VAPs with the WLAN ID 13 and ID 14, which cannot be occupied by other WLAN services.
Bind the WDS profile to an AP radio.
- Run the ap-id ap-id, ap-mac ap-mac, or ap-name ap-name command to enter the AP view.
- Run the radio radio-id command to enter the radio view.
Run the wds-profile profile-name command to bind the WDS profile to the AP radio.
By default, no WDS profile is bound to an AP radio.
A WDS link uses the VAPs with the WLAN ID 13 and ID 14, which cannot be occupied by other WLAN services.
