Cisco Systems OL-6217-01 manual Configuring the WDS on the WLSM

Cisco Structured Wireless-Aware Network (SWAN) Implementation Guide

Implementing the Cisco SWAN Framework

Step 2 Create the VLAN between the supervisor and WLSM:

sup-720(config)#interface Vlan <vlan number>

sup-720(config-int)#ip address <ip address> <network mask>

sup-720(config-int)# exit

Step 3 Define the VLAN created in step 2 as the VLAN between the supervisor and WLSM.

sup-720(config)#wlan module <wlsm module number> allowed-vlan <vlan number>

The WLSM module number corresponds to the slot in which the WLSM resides. The vlan number is the number of the VLAN created in Step 2.

Step 4 Create a loopback interface to serve as a tunnel source.

sup-720(config)#interface Loopback <Loopback number> sup-720(config-int)#ip address <ip address> <network mask> sup-720(config-int)#exit

Step 5 Define the multi-point GRE tunnel interface.

sup-720(config)#interface Tunnel <Tunnel Number> sup-720(config-int)#ip address <ip address> <network mask> sup-720(config-int)#ip helper-address <dhcp server address> sup-720(config-int)#ip dhcp snooping packets sup-720(config-int)#tunnel source Loopback <Loopback interface number> sup-720(config-int)#tunnel mode gre multipoint sup-720(config-int)#mobility network-id <mobility group number> sup-720(config-int)#mobility trust

sup-720(config-int)# mobility broadcast sup-720(config-int)# exit

The tunnel source refers to the interface created in Step 4. The <mobility group number> defines the mobility group. The same identifier is used on the infrastructure access points. The mobility trust command is an optional command allowing WLAN clients with static IP addresses. Without the mobility trust command, these clients are denied access to the network. The mobility broadcast command is an optional command that instructs the supervisor to forward broadcast traffic from one multi-point GRE tunnel leg onto the other tunnel legs. Without this command, broadcast traffic is not forwarded.

Step 6 Repeat Steps 4 and 5 for each desired mobility group.

Step 7 Define the SNMP communities as follows:

sup-720(config)#snmp-server community <snmp read-only community name> RO

sup-720(config)#snmp-server community <snmp read-write community> RW

Unlike the SNMP configurations on the WLSM and access points, an SNMP view definition is not required by the supervisor.

Configuring the WDS on the WLSM

In this section, the configuration steps required to set up the WLSM and WDS on the WLSM are provided. Configuring the WDS on the WLSM is very similar to configuring WDS on the access points, with a few variations. The necessary tasks are as follows:

•Define the WLAN VLAN to the supervisor

•Define SNMP communities

•Define a host name for the WLSM

•Define AAA parameters for infrastructure authentication
