Syntax Description
config mesh astools
config mesh backhaul rate-adapt
To globally configure the backhaul Tx rate adaptation (universal access) settings for indoor and outdoor mesh access points, use the config mesh backhaul rate-adapt command.
Syntax Description
Usage Guidelines
To use this command, mesh backhaul with client access must be enabled by using the config mesh client-access command.
NoteAfter this feature is enabled, all mesh access points reboot.
config mesh backhaul slot
Syntax Description
Usage Guidelines
For 2.4-GHz, only slot 0 and 1 are valid. If slot 0 is enabled, then slot 1 is automatically be disabled. If slot 0 is disabled, then slot 1 is automatically enabled. The config mesh backhaul slot command is applicable only to AP1522.
config mesh battery-state
config mesh client-access
To enable or disable client access to the mesh backhaul on indoor and outdoor mesh access points, use the config mesh client-access command.
Syntax Description
Usage Guidelines
Backhaul interfaces (802.11a radios) act as primary Ethernet interfaces. Backhauls function as trunks in the network and carry all VLAN traffic between the wireless and wired network. No configuration of primary Ethernet interfaces is required.
When this feature is enabled, Cisco Aironet 1520 series (152x) mesh access points allow wireless client association over the 802.11a radio, which implies that a 152x mesh access point can carry both backhaul traffic and 802.11a client traffic over the same 802.11a radio.
When this feature is disabled, the 152x carries backhaul traffic over the 802.11a radio and allows client association only over the 802.11b/g radio.
Examples
This example shows how to enable client access extended to allow a wireless client association over the 802.11a radio:
> config mesh client-access enable extended Enabling client access on both backhaul slots Same BSSIDs will be used on both slots All Mesh AP will be rebooted Are you sure you want to start? (y/N)YThis example shows how to restrict a wireless client association to the 802.11b/g radio:
> config mesh client-access disable All Mesh AP will be rebooted Are you sure you want to start? (Y/N) Y Backhaul with client access is cancelled.config mesh ethernet-bridging vlan-transparent
To configure how a mesh access point handles VLAN tags for Ethernet bridged traffic, use the config mesh ethernet-bridging vlan-transparent command.
Syntax Description
Usage Guidelines
VLAN transparent is enabled as a default to ensure a smooth software upgrade from 4.1.192.xxM releases to release 5.2. Release 4.1.192.xxM does not support VLAN tagging.
config mesh full-sector-dfs
To globally enable or disable full-sector Dynamic Frequency Selection (DFS) on mesh access points, use the config mesh full-sector-dfs command.
Syntax Description
Usage Guidelines
This command instructs the mesh sector to make a coordinated channel change on the detection of a radar signal. For example, if a mesh access point (MAP) detects a radar signal, the MAP will notify the root access point (RAP), and the RAP will initiate a sector change.
All MAPs and the RAP that belong to that sector go to a new channel, which lowers the probability of MAPs stranding when radar is detected on the current backhaul channel, and no other valid parent is available as backup.
Each sector change causes the network to be silent for 60 seconds (as dictated by the DFS standard).
It is expected that after a half hour, the RAP will go back to the previously configured channel, which means that if radar is frequently observed on a RAP's channel, it is important that you configure a different channel for that RAP to exclude the radar affected channel at the controller.
config mesh linkdata
Syntax Description
Usage Guidelines
MAC filtering uses the local MAC filter on the controller by default.
When external MAC filter authorization is enabled, if the MAC address is not found in the local MAC filter, then the MAC address in the external RADIUS server is used.
MAC filtering protects your network against rogue mesh access points by preventing access points that are not defined on the external server from joining.
Before employing external authentication within the mesh network, the following configuration is required:
Examples
This example shows how to enable external MAC address filtering on access point AP001d.710d.e300:

Syntax Description
Usage Guidelines
The following warning message appears when you run a linktest that might oversubscribe the link:
Warning! Data Rate (100 Mbps) is not enough to perform this link test on packet size (2000bytes) and (1000) packets per second. This may cause AP to disconnect or reboot. Are you sure you want to continue?
Examples
This example shows how to verify client access between mesh access points SB_MAP1 and SB_RAP2 at 36 Mbps, 20 fps, 100 frame size, and 15 second duration:

config mesh lsc
config mesh multicast
To configure multicast mode settings to manage multicast transmissions within the mesh network, use the config mesh multicast command.
Syntax Description
Usage Guidelines
Multicast for mesh networks cannot be enabled using the controller GUI.
Mesh multicast modes determine how bridging-enabled access points mesh access points (MAPs) and root access points (RAPs) send multicasts among Ethernet LANs within a mesh network. Mesh multicast modes manage non-LWAPP multicast traffic only. LWAPP multicast traffic is governed by a different mechanism.
You can use the controller CLI to configure three mesh multicast modes to manage video camera broadcasts on all mesh access points. When enabled, these modes reduce unnecessary multicast transmissions within the mesh network and conserve backhaul bandwidth.
When using in-out mode, it is important to properly partition your network to ensure that a multicast sent by one RAP is not received by another RAP on the same Ethernet segment and then sent back into the network.
config mesh parent preferred
To configure a preferred parent for a mesh access point, use the config mesh parent preferred command.
Syntax Description
Command History
Usage Guidelines
A child AP selects the preferred parent based on the following conditions:
- The preferred parent is the best parent.
- The preferred parent has a link SNR of at least 20 dB (other parents, however good, are ignored).
- The preferred parent has a link SNR in the range of 12 dB and 20 dB, but no other parent is significantly better (that is, the SNR is more than 20 percent better). For an SNR lower than 12 dB, the configuration is ignored.
- The preferred parent is not blacklisted.
- The preferred parent is not in silent mode because of dynamic frequency selection (DFS).
- The preferred parent is in the same bridge group name (BGN). If the configured preferred parent is not in the same BGN and no other parent is available, the child joins the parent AP using the default BGN.
Examples
The following example shows how to configure a preferred parent with the MAC address 00:21:1b:ea:36:60 for a mesh access point myap1:
(Cisco Controller) >config mesh parent preferred myap1 00:21:1b:ea:36:60The following example shows how to clear a preferred parent for a mesh access point myap1 by using the keyword none:
(Cisco Controller) >config mesh parent preferred myap1 noneconfig mesh public-safety
To enable or disable the 4.9-GHz public safety band for mesh access points, use the config mesh public-safety command.
Syntax Description
config mesh radius-server
To enable or disable external authentication for mesh access points, use the config mesh radius-server command.
Syntax Description
config mesh range
To globally set the maximum range between outdoor mesh root access points (RAPs) and mesh access points (MAPs), use the config mesh range command.
Syntax Description
Usage Guidelines
After this command is enabled, all outdoor mesh access points reboot. This command does not affect indoor access points.
config mesh secondary-backhaul
To configure a secondary backhaul on the mesh network, use the config mesh secondary-backhaul command.
config mesh secondary-backhaul { enable [ force-same-secondary-channel] | disable [ rll-retransmit | rll-transmit]}
Syntax Description
Usage Guidelines
NoteThe secondary backhaul access feature is not supported by Cisco 1520 and 1524 indoor mesh access points in the 5.2 release.
This command uses a secondary backhaul radio as a temporary path for traffic that cannot be sent on the primary backhaul due to intermittent interference.

Syntax Description
config mesh slot-bias
To enable or disable slot bias for serial backhaul mesh access points, use the config mesh slot-bias command.
Syntax Description
Usage Guidelines
Follow these guidelines when using this command:
- The config mesh slot-bias command is a global command and therefore applicable to all 1524SB APs associated with the same controller.
- Slot bias is applicable only when both slot 1 and slot 2 are available. If a slot radio does not have a channel that is available because of dynamic frequency selection (DFS), the other slot takes up both the uplink and downlink roles.
- If slot 2 is not available because of hardware issues, slot bias functions normally. Corrective action should be taken by disabling the slot bias or fixing the antenna.
