Using the CLI to Configure Mobility Groups
Follow these steps to configure mobility groups using the CLI.
Step 1
Enter
show mobility summary
to check the current mobility settings.
Step 2
Enter
config mobility group name
group_name
to create a mobility group.
Note
Enter up to 31 case-sensitive ASCII characters for the group name. Spaces are not allowed in
mobility group names.
Step 3
Enter
config mobility group member add
mac-address
ip-addr
to add a group member.
Note
Enter
config mobility group member delete
mac-address
ip-addr
if you want to delete a group
member.
Step 4
Enter
show mobility summary
to verify the mobility configuration.
Step 5
Enter
save
config
to save your settings.
Step 6
Repeat this procedure on every controller to be included in the mobility group. All controllers in the
mobility group must be configured with the MAC address and IP address of all other mobility group
members.
Configuring Auto-Anchor Mobility
You can use auto-anchor mobility (or guest WLAN mobility
)
to improve load balancing and security for
roaming clients on your wireless LANs. Under normal roaming conditions, client devices join a wireless
LAN and are anchored to the first controller that they contact. If a client roams to a different subnet, the
controller to which the client roamed sets up a foreign session for the client with the anchor controller.
However, using the auto-anchor mobility feature, you can specify a controller or set of controllers as the
anchor points for clients on a wireless LAN.
In auto-anchor mobility mode, a subset of a mobility group is specified as the anchor controllers for a
WLAN. You can use this feature to restrict a WLAN to a single subnet, regardless of a client’s entry
point into the network. Clients can then access a guest WLAN throughout an enterprise but still be
restricted to a specific subnet. Auto-anchor mobility can also provide geographic load balancing because
the WLANs can represent a particular section of a building (such as a lobby, a restaurant, and so on),
effectively creating a set of home controllers for a WLAN. Instead of being anchored to the first
controller that they happen to contact, mobile clients can be anchored to controllers that control access
points in a particular vicinity.
