Switch and Controller Software Compatibility
The switch and controller run two different software images and interaction between them is minimal. These software images are packaged and upgraded separately. These images must be compatible for the wireless LAN controller switch to operate correctly. If the image versions are not compatible, the wireless LAN controller switch could stop functioning. Table 5 is the compatibility matrix for Catalyst 3750 and wireless controller.
Table 5 Catalyst 3750G Wireless LAN Controller Switch Software Compatibility
Cisco IOS Release 12.2(25)FZ
Cisco Software Release 4.0.x.0
If the switch and controller software are not compatible, you need to upgrade or downgrade the software so that they are compatible:
•
•
Note
You upgrade the Catalyst 3750 software as with any other Catalyst 3750 switch. See the Release Notes for the Catalyst 3750 switch for Cisco IOS Release 12.2(25)SEE for the procedure. You can upgrade the controller software directly by using TFTP after the controller management IP address is configured or directly from the Wireless Control System (WCS), an application using SNMP, as you would for a standalone 4402 controller. See the CiscoWireless LAN Controller Configuration Guide Release 4.0 on cisco.com.
Understanding the Integrated Wireless LAN Controller Switch
The Catalyst 3750 Integrated Wireless LAN Controller Switch is a Layer 3 IEEE 802.3af-compliant switch with an integrated wireless LAN controller capable of supporting up to 25 or 50 lightweight access points. The switch combines the Catalyst 3750 infrastructure with wireless LAN controller and access points to provide an IEEE 802.11 mobile wireless solution.
The wireless LAN controller switch has these features:
•
•
•
•
•
•
•
•
•
The Catalyst 3750 switch software handles all the switch features, including routing, bridging, access control lists (ACLs), and quality of service (QoS). The controller handles all wireless functionality. The Catalyst 3750 switch and the internal wireless controller are connected internally through two Gigabit Ethernet links. These links are automatically configured to direct the switch wireless traffic toward the controller, requiring minimal configuration by the user.
You can manage the switch by the switch CLI, eXpresso, or CNA. You can manage the controller from the controller CLI, the embedded controller GUI, or WCS. You can access the controller command-line interface (CLI) from the switch CLI.
The Wireless LAN Controller Switch and Switch Stacks
The wireless LAN controller switch can coexist with other Catalyst 3750 switches in a switch stack. However, for controller functionality, all switches in the stack should be running Cisco IOS Release 12.2(25)FZ. To support wireless controller redundancy, there should be at least two wireless LAN controller switches in a stack. A stack should contain no more than four wireless LAN controller switches.
The wireless LAN controller switch can be a master switch or a member switch in a stack. Stacking behavior for a wireless LAN controller switch is consistent with that of other Catalyst 3750 switches. For wireless functionality, you can configure the access points so that if one wireless LAN controller switch in a stack shuts down, the access points and wireless clients controlled by the controller in this switch automatically migrate to the controller of another wireless LAN controller switch in the stack, The traffic for wireless clients experiences a short interruption due to reassociation and reauthentication.
In a switch stack, each switch holds a unique switch number (1 to 9). This same switch number is used to access the controller in a switch in a stack or a standalone switch, where the switch number is 1 by default. For example, to access the controller in stack member 3, use the session 3 processor 1 privileged EXEC command (where processor 1 represents the controller). To access the controller in a standalone switch, use the command session 1 processor 1.
Note
Controller and Switch Interaction
The Catalyst 3750 switch and its internal controller are managed separately. You can manage the switch by using the 3750 CLI, eXpresso, or CNA. You can manage the controller by using the controller CLI, the embedded controller GUI, or WCS. To use the GUI or WCS, you must configure the controller management interface, either through the 3750 CLI, the controller CLI, eXpresso, or Express Setup. See the Catalyst 3750 Integrated Wireless LAN Controller Switch Getting Started Guide for how to use eXpresso and express setup. To access the controller CLI, enter the session switch-number processor 1 privileged EXEC command.
When you power on the wireless LAN controller switch, POST is performed separately by both the Catalyst 3750 switch and by the wireless controller. Both maintain separate configuration files, which must be separately saved or cleared.
Note these switch and controller interactions:
•

Internal Ports
The two internal Gigabit Ethernet ports connect the switch and controller hardware. These ports carry the wireless control and data traffic, as well as the switch and controller management traffic. The links are automatically configured to allow internal traffic between the switch and the controller. In addition, an internal VLAN ID is chosen by the Catalyst 3750 switch and communicated to the controller. You cannot configure the internal VLAN.
In order to operate correctly with the controller, the internal ports (identified as Gigabit Ethernet ports 27 and 28) must have these characteristics:
•
•
•
•
•
•
The ports are automatically configured with these parameters, including membership in an EtherChannel port group, and you should not change these configurations. However, it is important that the EtherChannel port group should be unique on the switch and in the stack; no other ports should belong to the port group that contains the internal ports. If a switch stack includes more than one wireless LAN controller switch, the internal port channel number must be different within each switch.
You can reconfigure the port channel number if necessary, and you can explicitly configure these ports with other parameters. However, you should not configure features that limit traffic flow, such as ACLs, VLAN maps, and IP source guard.
Configuring the Integrated Wireless LAN Controller Switch
You configure the wireless LAN controller switch by using the same commands that you use to configure any Catalyst 3750 switch (standalone or in a switch stack). This section describes only the configuration specific to the wireless LAN controller switch.
Configuring the Internal Ports
As explained in the "Internal Ports" section, the internal ports connecting the switch and controller are Gigabit Ethernet ports 27 and 28. You should not change the parameters defined in that section as required for switch and controller interaction. This is a sample configuration for the internal ports:
!interface Port-channel41switchport trunk encapsulation dot1qswitchport mode trunkswitchport nonegotiateend!interface GigabitEthernet2/0/27description This interface is permanently connected to wireless controllerswitchport trunk encapsulation dot1qswitchport mode trunkswitchport nonegotiateno cdp enablechannel-group 41 mode onspanning-tree portfast trunkend!interface GigabitEthernet2/0/28description This interface is permanently connected to wireless controllerswitchport trunk encapsulation dot1qswitchport mode trunkswitchport nonegotiateno cdp enablechannel-group 41 mode onspanning-tree portfast trunkendYou can also configure other parameters on these ports in interface configuration mode. For example, by default, all traffic on all VLANs are sent to the controller. You should limit the VLANs that are allowed on the internal trunk by using the switchport trunk allowed vlan interface configuration command. You enter interface configuration mode for an internal port the same as any other port. For example, if the wireless LAN controller switch is a standalone switch or switch number 1 in a stack, use this command to enter interface configuration mode for internal port 27:
Switch(config)# gigabitethernet1/0/27Switch(config-if)#The internal ports are automatically configured to belong to a static Ether Channel that has PAgP and LACP disabled. No other ports (internal or otherwise) in the switch stack should be members of this EtherChannel. To identify the internal port channel number that the switch has automatically configured, use the show etherchannel summary privileged EXEC command.
This output shows that the internal ports on switch 1 in the stack belong to port channel 40. You should not use this port channel for any other ports in the stack.
Switch# show etherchannel summaryFlags: D - down P - in port-channelI - stand-alone s - suspendedH - Hot-standby (LACP only)R - Layer3 S - Layer2U - in use f - failed to allocate aggregatoru - unsuitable for bundlingw - waiting to be aggregatedd - default portNumber of channel-groups in use: 36Number of aggregators: 36Group Port-channel Protocol Ports------+-------------+-----------+----------------------------1 Po1(SD) LACP Gi2/0/1(D)<output truncated>33 Po33(SD) LACP Gi2/0/17(D)40 Po40(SU) - Gi1/0/27(P) Gi1/0/28(P)Reconfiguring the Internal Ports
You should not modify the automatic configuration of the internal ports, but if they somehow lose the automatic configuration, you should reconfigure the ports to that configuration.
Beginning in privileged EXEC mode, follow these steps to configure the internal ports to the automatic configuration:
Accessing the Controller
You can configure the internal wireless controller by using the embedded controller GUI, WCS, or the controller CLI. You use the management interface IP address to access the controller GUI from a browser or from WCS.
You access the controller CLI from the master switch in a switch stack or from a standalone wireless LAN controller switch by using the session stack-member-number processor 1privileged EXEC command. This command takes you to the controller CLI to enter controller configuration commands. This example assumes that switch 2 in a stack is the wireless LAN controller switch:
Switch# session 1 processor 1(Cisco Controller)User:See the CiscoWireless LAN Controller Configuration Guide Release 4.0 for controller CLI configuration information.
Displaying Internal Wireless Controller Information
To use access the controller GUI, you need to enter the management interface IP address. From the switch CLI, you can enter the show platform wireless-controller privileged EXEC command with or without keywords to display the management IP address, as well as other information about the internal controller as shown in this example.
Switch# show platform wireless-controllerWireless Controller in Switch 2Operational Status of the Controller : operationalService VLAN : 4095Service Port Mac Address : 000b.8540.3783Service IP Address : 127.0.1.2Management IP Address : 22.2.2.2Management VLAN : 7Software Version : 3.3.0.3Keepalive Version(controller/switch) : 1/1Keepalives Missed : 0Controller accepts http/https : 0/1Controller's Status Line : upWatchdog resets of Controller : 0Controller resets total : 0Unacknowledged control messages : 0Wireless Controller in Switch 3Operational Status of the Controller : operationalService VLAN : 4095Service Port Mac Address : 000b.8540.33e3Service IP Address : 127.0.1.3Management IP Address : 8.8.8.8Management VLAN : 8Software Version : 3.3.0.3Keepalive Version(controller/switch) : 1/1Keepalives Missed : 0Controller accepts http/https : 0/1Controller's Status Line : upWatchdog resets of Controller : 0Controller resets total : 0Unacknowledged control messages : 0See the "show platform wireless-controller" section.

Note
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete list of Cisco TAC contacts, go to this URL:

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—An existing network is down, or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of the network is impaired, while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
