Mobility Commands

mobility anchor

To configure mobility sticky anchoring, use the mobility anchor sticky command. To disable the sticky anchoring, use the no form of the command.

To configure guest anchoring, use the mobility anchor ip-address command.

To delete the guest anchor, use the no form of the command.

To configure the device as an auto-anchor, use the mobility anchor command.

mobility anchor { ip-address | sticky }

no mobility anchor { ip-address | sticky }

Syntax Description

sticky

The client is anchored to the first switch that it associates.

Note

This command is by default enabled and ensures low roaming latency. This ensures that the point of presence for the client does not change when the client joins the mobility domain and roams within the domain.

ip-address

Configures the IP address for the guest anchor switch to this WLAN.

Command Default

Sticky configuration is enabled by default.

Command Modes

WLAN Configuration

Command History

Release	Modification
Cisco IOS XE 3.2SE	This command was introduced.
Cisco IOS XE 3.3SE	The auto-anchor configuration required the device IP address to be entered prior to the Cisco IOS XE 3.3SE release; with this release, if no IP address is given, the device itself becomes an anchor; you do not have to explicitly specify the IP address.

Usage Guidelines

The wlan_id or guest_lan_id must exist and be disabled.
Auto-anchor mobility is enabled for the WLAN or wired guest LAN when you configure the first mobility anchor.
Deleting the last anchor disables the auto-anchor mobility feature and resumes normal mobility for new associations.
Mobility uses the following ports, that are allowed through the firewall:
- 16666
- 16667
- 16668

Examples

This example shows how to enable the sticky mobility anchor:

Switch(config-wlan)# mobility anchor sticky

This example shows how to configure guest anchoring:

Switch(config-wlan)# mobility anchor 209.165.200.224

This example shows how to configure the device as an auto-anchor:

Switch(config-wlan)# mobility anchor

wireless mobility

To configure the interswitch mobility manager, use the wireless mobility command.

wireless mobility { dscp value }

Syntax Description

dscp value

Configures the Mobility interswitch DSCP value.

Command Default

wireless mobility controller

To configure mobility controller settings, use the wireless mobility controller command. To remove a mobility controller settings, use the no form of the command.

wireless mobility controller peer-group peer-group-name [ bidge-domain-id id | member ip ip-address [ public-ip | public-ip-address ] | multicast ip multicast-address ]

nowireless mobility controller peer-group peer-group-name [ bidge-domain-id id | member ip ip-address [ public-ip | public-ip-address ] | multicast ip multicast-address ]

Usage Guidelines

In the Converged Access solution, WLANs are mapped to VLANs, and VLANs are usually mapped to subnets. For seamless roaming, the same VLAN configured on two controllers is expected to be mapped to the same subnet. This identical mapping from one controller to the next is important for roaming, because the controllers taking care of the roaming event need to determine if they need:

To address a Layer 2 roaming event (when WLAN to VLAN and subnet mapping are identical on the anchor and the foreign controller), or
a Layer 3 roaming event (when WLAN to VLAN and subnet mapping are different between the anchor and the foreign controller).

This determination is made by comparing the WLAN SSID string and the VLAN ID between controllers. In cases where the WLAN SSID and VLAN ID are identical, the expectation is that the subnet associated to the VLAN is identical as well.

There may be cases where this mapping is not identical. For example, suppose that WLAN1 on controller 1 is mapped to VLAN 14, and that VLAN 14 on controller1 is mapped to the subnet 10.10.14.0/24. Also suppose that WLAN 1 on controller2 is mapped to VLAN 14, but that VLAN 14 on controller2 is mapped to this subnet 172.31.24.0/24. Controllers 1 and 2 will compare WLAN1 and the associated VLAN and conclude that they are addressing a Layer 2 roaming event, whereas the roaming even is Layer 3, as VLAN 14 does not have the same Layer 3 significance on both controllers.

When this disconnect between VLANs and their associated subnet occurs, you may want to configure your Converged Access controllers for different bridge domain IDs. Two controllers in the same bridge domain ID are expected to have the same VLAN to subnet mapping. We recommend that you configure the same bridge domain ID on all controllers that share the same VLAN to subnet mapping, and between which roaming is expected.

Examples

This example shows how to configure a switch bridge domain ID.

Switch (config)# wireless mobility controller peer-group SPG1 bridge-domain-id 111

Examples

This example shows how to create and configure a switch peer group with a bridge ID of 111:

Switch(config)# controller peer-group TestDocPeerGroup bridge-domain-id 111

Examples

This example shows how to disable a switch peer group with a bridge ID of 111:

Switch(config)# no controller peer-group TestDocPeerGroup bridge-domain-id 111

Examples

This examples shows the configuration for a NATed member (the IP 172.19.13.15 is outside the NAT):

Switch (config)# wireless mobility group ip 1.4.91.2 public-ip 172.19.13.15

Examples

Usage Guidelines

The mobility group is used when there is more than one Mobility Controller (MC) in a given deployment. The mobility group can be assigned with a name or it can use the default group name. The mobility group members need to be configured on all the members of the group to roam within the group.

Examples

This example shows how to add a member in a mobility group:

Switch(config)# mobility group member ip 10.104.171.101 group TestDocGroup

wireless mobility group name

To configure hte mobility domain name, use the wireless mobility group name command. To remove the mobility domain name, use the no form of the command.

Note

If you are configuring the mobility group in a network where network address translation (NAT) is enabled, enter the IP address that is sent to the controller from the NAT device rather than the controller’s management interface IP address. Otherwise, mobility will fail among controllers in the mobility group.

wireless mobility load-balance

This command is used to load-balance the mobile clients on a mobility anchor (MA) from a switch peer group (SPG) that is least loaded and is chosen to act as the point of presence for the mobile client.

To configure the mobility load-balance status, use the wireless mobility load-balance command.

To disable the mobility load-balance, use the no wirelessmobility load-balanceform of the command.

To configure the client load on the switch where mobility load-balance is turned on, use the no wirelessmobility load-balance threshold form of the command.
