Optimizing Dual 5G Mode in AP for Serial Backhaul Support on Cisco Catalyst IW9167E Heavy Duty Series Access Point	This feature enhances the performance and efficiency of a wireless network by optimizing the use of dual 5G radios in an AP for backhaul. In this feature, AP operates in the dual 5G mode using two 5G radios. You can enable backhaul on two 5G radios. The two backhaul radios provide uplink and downlink access to maximize throughput over multiple mesh hops. Note   For the dual 5G serial backhaul, ensure that slot 2 operates in 5G mode when enabling mesh dual 5G serial backhaul. When slot 2 operates in 6 GHz, AP is unable to be configured in mesh mode. The backhaul root AP (RAP) does not support multiple downlink channels. When you configure mesh mode in AP, block the 6G band for slot 2 as it does not support both backhaul and access. By default, the following actions are performed without any configuration change except enabling dual-5G: Mesh access point (MAP) seeks for a primary device on all enabled radios. MAP performs uplink and downlink on the same slot while other slots are in access mode.
Power Profile Support with 30-watts Power over Ethernet (PoE) on Cisco Catalyst IW9167I Heavy Duty Access Point	The AP power policy allows you to define the power budget utilization available for an AP, wherein, you can define a set of policies for different interfaces on an AP. From this release, Cisco Catalyst IW9167I Heavy Duty AP supports Power policy AP feature especially when AP works with 802.3at power. PoE+ is a new interface introduced in Cisco Catalyst IW9167I Heavy Duty AP, in addition to the Ethernet and LAN interfaces. AP is now powered by 30W through either 802.3at or 802.3bt standards, offering versatility in deployment and ensuring high-performance wireless connectivity. To enable flexible power policy, a power profile must be configured on the controller, extending the AP Join profile. The power profile supports local and FlexConnect modes but is unsupported in mesh mode.

The following subsections list the hardware and software required to access the Cisco Catalyst 9800 Controller GUI.

Table 8. Hardware Requirements

Processor Speed	DRAM	Number of Colors	Resolution	Font Size
233 MHz minimum2	512 MB3	256	1280 x 800 or higher	Small

Software Requirements

Operating Systems:

• Windows 7 or later

• Mac OS X 10.11 or later

Browsers:

• Google Chrome: Version 59 or later (on Windows and Mac)

• Microsoft Edge: Version 40 or later (on Windows)

• Safari: Version 10 or later (on Mac)

• Mozilla Firefox: Version 60 or later (on Windows and Mac)

Note	Firefox Version 63.x is not supported.

The controller GUI uses Virtual Terminal (VTY) lines for processing HTTP requests. At times, when multiple connections are open, the default number of VTY lines of 15 set by the device might get exhausted. Therefore, we recommend that you increase the number of VTY lines to 50.

To increase the VTY lines in a device, run the following commands in the following order:

1. device# configure terminal

2. device(config)# line vty 50

   A best practice is to configure the service tcp-keepalives to monitor the TCP connection to the device.

3. device(config)# service tcp-keepalives-in

4. device(config)# service tcp-keepalives-out

Ensure that you familiarize yourself with the following points before proceeding with the upgrade:

• When you upgrade from Cisco IOS XE Dublin 17.12.3 to 17.12.4 or Cisco IOS XE 17.15.1, the Cisco Catalyst Wi-Fi 6 APs fail to upgrade the AP image.

  Workaround:

  • Reboot the impacted APs through the power cycle.

Caution

During controller upgrade or reboot, if route processor ports are connected to any Cisco switch, ensure that the route processor ports are not flapped (shut/no shut process). Otherwise, it may lead to a kernel crash.

Cisco Wave 2 APs may get into a boot loop when upgrading software over a WAN link. For more information, see: https://www.cisco.com/c/en/us/support/docs/wireless/catalyst-9800-series-wireless-controllers/220443-how-to-avoid-boot-loop-due-to-corrupted.html.

The following Wave 1 APs are not supported from 17.4 to 17.9.2, 17.10.x, 17.11.x, 17.13.x, 17.14.x, and 17.15.x:

• Cisco Aironet 1700 Series Access Point

• Cisco Aironet 2700 Series Access Point

• Cisco Aironet 3700 Series Access Point

Note

Support for the above APs was reintroduced from Cisco IOS XE Cupertino 17.9.3. Support for these APs does not extend beyond the normal product lifecycle support. Refer to the individual End-of-Support bulletins on Cisco.com. Feature support is on parity with the 17.3.x release. Features introduced in 17.4.1 or later are not supported on these APs in the 17.9.3 release. You can migrate directly to 17.9.3 from 17.3.x, where x=4c or later. Although the Cisco Aironet 1570 Series APs are not supported in Cisco IOS XE 17.14.1, the APs can still join the network.

• From Cisco IOS XE Dublin 17.10.x, Key Exchange and MAC algorithms like diffie-hellman-group14-sha1, hmac-sha1, hmac-sha2-256, and hmac-sha2-512 are not supported by default and it may impact some SSH clients that only support these algorithms. If required, you can add them manually. For information on manually adding these algorithms, see the SSH Algorithms for Common Criteria Certification document available at: https://www.cisco.com/c/en/us/td/docs/routers/ios/config/17-x/sec-vpn/b-security-vpn/m_sec-secure-shell-algorithm-ccc.html

• If APs fail to detect the backup image after running the archive download-sw command, perform the following steps:

  1. Upload the image using the no-reload option of the archive download-sw command:

     Device# archive download-sw /no-reload tftp://<tftp_server_ip>/<image_name>

  2. Restart the CAPWAP process using capwap ap restart command. This allows the AP to use the correct backup image after the restart (reload is not required.)

     Device# capwap ap restart 

     Caution

     The AP will lose connection to the controller during the join process. When the AP joins the new controller, it will see a new image in the backup partition. So, the AP will not download a new image from the controller.

• Fragmentation lower than 1500 is not supported for the RADIUS packets generated by wireless clients in the Gi0 (OOB) interface.

• Cisco IOS XE allows you to encrypt all the passwords used on the device. This includes user passwords and SSID passwords (PSK). For more information, see the "Password Encryption" section of the Cisco Catalyst 9800 Series Configuration Best Practices document.

• While upgrading to Cisco IOS XE 17.3.x and later releases, if the ip http active-session-modules none command is enabled, you will not be able to access the controller GUI using HTTPS. To access the GUI using HTTPS, run the following commands in the order specified below:

  1. ip http session-module-list pkilist OPENRESTY_PKI

  2. ip http active-session-modules pkilist

• Cisco Aironet 1815T OfficeExtend Access Point will be in local mode when connected to the controller. However, when it functions as a standalone AP, it gets converted to FlexConnect mode.

• The Cisco Catalyst 9800-L Wireless Controller may fail to respond to the BREAK signals received on its console port during boot time, preventing users from getting to the ROMMON. This problem is observed on the controllers manufactured until November 2019, with the default config-register setting of 0x2102. This problem can be avoided if you set config-register to 0x2002. This problem is fixed in the 16.12(3r) ROMMON for Cisco Catalyst 9800-L Wireless Controller. For information about how to upgrade the ROMMON, see the Upgrading ROMMON for Cisco Catalyst 9800-L Wireless Controllers section of the Upgrading Field Programmable Hardware Devices for Cisco Catalyst 9800 Series Wireless Controllers document.

• By default, the controller uses a TFTP block size value of 512, which is the lowest possible value. This default setting is used to ensure interoperability with legacy TFTP servers. If required, you can change the block size value to 8192 to speed up the transfer process, using the ip tftp blocksize command in global configuration mode.

• We recommend that you configure the password encryption aes and the key config-key password-encrypt key commands to encrypt your password.

• If the following error message is displayed after a reboot or system crash, we recommend that you regenerate the trustpoint certificate:

   ERR_SSL_VERSION_OR_CIPHER_MISMATCH

  Use the following commands in the order specified below to generate a new self-signed trustpoint certificate:

  1. device# configure terminal

  2. device(config)# no crypto pki trustpoint trustpoint_name

  3. device(config)# no ip http server

  4. device(config)# no ip http secure-server

  5. device(config)# ip http server

  6. device(config)# ip http secure-server

  7. device(config)# ip http authentication local/aaa

• Do not deploy OVA files directly to VMware ESXi 6.5. We recommend that you use an OVF tool to deploy the OVA files.

• Ensure that you remove the controller from Cisco Prime Infrastructure before disabling or enabling Netconf-YANG. Otherwise, the system may reload unexpectedly.

• Unidirectional Link Detection (UDLD) protocol is not supported.

• SIP media session snooping is not supported on FlexConnect local switching deployments.

• The Cisco Catalyst 9800 Series Wireless Controllers (C9800-CL, C9800-L, C9800-40, and C9800-80) support a maximum of 14,000 leases with internal DHCP scope.

• Configuring the mobility MAC address using the wireless mobility mac-address command is mandatory for both HA and 802.11r.

• If you have Cisco Catalyst 9120 (E/I/P) and Cisco Catalyst 9130 (E) APs in your network and you want to downgrade, use only Cisco IOS XE Gibraltar 16.12.1t. Do not downgrade to Cisco IOS XE Gibraltar 16.12.1s.

• The following SNMP variables are not supported:

  • CISCO-LWAPP-WLAN-MIB: cLWlanMdnsMode

  • CISCO-LWAPP-AP-MIB.my: cLApDot11IfRptncPresent, cLApDot11IfDartPresent

• If you are upgrading from Cisco IOS XE Gibraltar 16.11.x or an earlier release, ensure that you unconfigure the advipservices boot-level licenses on both the active and standby controllers using the no license boot level advipservices command before the upgrade. Note that the license boot level advipservices command is not available in Cisco IOS XE Gibraltar 16.12.1s and 16.12.2s.

• The Cisco Catalyst 9800 Series Wireless Controller has a service port that is referred to as GigabitEthernet 0 port.

  The following protocols and features are supported through this port:

  • Cisco Catalyst Center

  • Cisco Smart Software Manager

  • Cisco Prime Infrastructure

  • Telnet

  • Controller GUI

  • HTTP

  • HTTPS

  • Licensing for Smart Licensing feature to communicate with CSSM

  • SSH

• During device upgrade using GUI, if a switchover occurs, the session expires and the upgrade process gets terminated. As a result, the GUI cannot display the upgrade state or status.

• From Cisco IOS XE Bengaluru 17.4.1 onwards, the telemetry solution provides a name for the receiver address instead of the IP address for telemetry data. This is an additional option. During the controller downgrade and subsequent upgrade, there is likely to be an issue—the upgrade version uses the newly named receivers, and these are not recognized in the downgrade. The new configuration gets rejected and fails in the subsequent upgrade. Configuration loss can be avoided when the upgrade or downgrade is performed from Cisco Catalyst Center.

• Communication between Cisco Catalyst 9800 Series Wireless Controller and Cisco Prime Infrastructure uses different ports:

  • All the configurations and templates available in Cisco Prime Infrastructure are pushed through SNMP and CLI, using UDP port 161.

  • Operational data for controller is obtained over SNMP, using UDP port 162.

  • AP and client operational data leverage streaming telemetry:

    • Cisco Prime Infrastructure to controller: TCP port 830 is used by Cisco Prime Infrastructure to push the telemetry configuration to the controller (using NETCONF).

    • Controller to Cisco Prime Infrastructure: TCP port 20828 is used for Cisco IOS XE 16.10.x and 16.11.x, and TCP port 20830 is used for Cisco IOS XE 16.12.x, 17.1.x and later releases.

• To migrate public IP address from 16.12.x to 17.x. ensure that you configure the service internal command. If you do not configure the service internal command, the IP address does not get carried forward.

• RLAN support with Virtual Routing and Forwarding (VRF) is not available.

• When you encounter the SNMP error SNMP_ERRORSTATUS_NOACCESS 6, it means that the specified SNMP variable is not accessible.

• We recommend that you perform a controller reload whenever there is a change in the controller's clock time to reflect an earlier time.

Note

The DTLS version (DTLSv1.0) is deprecated for Cisco Aironet 1800 based on latest security policies. Therefore, any new out-of-box deployments of Cisco Aironet 1800 APs will fail to join the controller and you will get the following error message: %APMGR_TRACE_MESSAGE-3-WLC_GEN_ERR: Chassis 1 R0/2: wncd: Error in AP Join, AP <AP-name>, mac:<MAC-address>Model AIR-AP1815W-D-K9, AP negotiated unexpected DTLS version v1.0 To onboard new Cisco Aironet 1800 APs and to establish a CAPWAP connection, explicitly set the DTLS version to 1.0 in the controller using the following configuration: config terminal ap dtls-version dtls_1_0 end Note that setting the DTLS version to 1.0 affects all the existing AP CAPWAP connections. We recommend that you apply the configuration only during a maintenance window. After the APs download the new image and join the controller, ensure that you remove the configuration.

To upgrade the field programmable hardware devices for Cisco Catalyst 9800 Series Wireless Controllers, see Upgrading Field Programmable Hardware Devices for Cisco Catalyst 9800 Series Wireless Controllers.

Important

Before you begin a downgrade process, you must manually remove the configurations which are applicable in the current version but not in older version. Otherwise, you might encounter an unexpected behavior.

• When you downgrade an AP from a higher version to Cisco IOS XE Amsterdam 17.3.x, the AP will not be accessible through SSH or the console due to the denial of the enable password, when the AP has not yet joined a controller. If the AP joins a controller, then the AP becomes accessible without any password denial.
