The Catalyst 3650 switches are the next generation of enterprise class stackable access layer switches that provide full convergence between wired and wireless networks on a single platform. This convergence is built on the resilience of new and improved 160-Gbps StackWise-160 and Cisco StackPower. Wired and wireless security and application visibility and control are natively built into the switch.
The Catalyst 3650 switches also support full IEEE 802.3 at Power over Ethernet Plus (PoE+), modular and field replaceable network modules, redundant fans, and power supplies. The Catalyst 3650 switches enhance productivity by enabling applications such as IP telephony, wireless, and video for a true borderless network experience.
The Cisco IOS XE software represents the continuing evolution of the preeminent Cisco IOS operating system. The Cisco IOS XE architecture and well-defined set of APIs extend the Cisco IOS software to improve portability across platforms and extensibility outside the Cisco IOS environment. The Cisco IOS XE software retains the same look and feel of the Cisco IOS software, while providing enhanced future-proofing and improved functionality.
For more information about the Cisco IOS XE software, see http://www.cisco.com/en/US/prod/collateral/iosswrel/ps9442/ps11192/ps11194/QA_C67-622903.html
- Support added for Cisco Aironet 3700 Series Access Points—The Cisco Aironet 3700 Series Access Points with the 802.11ac module is supported in this release. For more information about the AP, see http://www.cisco.com/en/US/products/ps13367/index.html .
- For information about open and resolved caveats, see “Caveats” section.
- HSRP version 2 support for IPv4 and IPv6—Improves management and troubleshooting of IP multicast addresses. Also addresses the restrictions in HSRP version 1, such as:
– Multicast address 184.108.40.206 is used to send HSRP hello messages. This address can conflict with Cisco Group Management Protocol (CGMP) leave processing. HSRP version 2 uses the new IP multicast address 220.127.116.11 to send hello packets instead of the multicast address of 18.104.22.168.
Stackable 24 10/100/1000 PoE+1 downlink ports, four 1-Gigabit SFP uplink ports, 640-W power supply
Table 2 lists the supported products of the Catalyst 3650 switch.
Table 3 lists the specific supported Cisco access points.
Table 4 lists the software compatibility matrix.
2.Prime Infrastructure 2.0 enables you to manage Cisco WLC 22.214.171.124 with the features of Cisco WLC 126.96.36.199 and earlier releases. Prime Infrastructure 2.0 does not support any features of Cisco WLC 188.8.131.52 including the new AP platforms.

Table 6 shows the mapping of the Cisco IOS XE version number and the Cisco IOS version number.
Note Although the show version output always shows the software image running on the switch, the model name shown at the end of this display is the factory configuration and does not change if you upgrade the software license.
- LAN Base feature set—Provides basic Layer 2+ features, including access control lists (ACLs) and quality of service (QoS) and up to 4094 VLANs.
- IP Base feature set—Provides Layer 2+ and basic Layer 3 features (enterprise-class intelligent services). These features include access control lists (ACLs), quality of service (QoS), ACLs, QoS, static routing, EIGRP stub routing, IP multicast routing, Routing Information Protocol (RIP), basic IPv6 management, the Open Shortest Path First (OSPF) Protocol, and support for wireless controller functionality.
- IP Services feature set—Provides a richer set of enterprise-class intelligent services and full IPv6 support. It includes all IP Base features plus full Layer 3 routing (IP unicast routing, IP multicast routing, and fallback bridging). The IP Services feature set includes protocols such as the Enhanced Interior Gateway Routing Protocol (EIGRP), the Open Shortest Path First (OSPF) Protocol, and support for wireless controller functionality.
Table 7 lists the client types on which the tests were conducted. The clients included laptops, handheld devices, phones, and printers.
- A switch stack containing a mix of Catalyst 3850 and Catalyst 3650 switches is not supported.
- Although visible in the CLI, the following commands are not supported:
- Although visible in the CLI, the authorize-lsc-ap command is not supported. (CSCui93659)
- The following features are not supported in Cisco IOS XE Release 3.3.0SE:

If IP device tracking is not required and neither dot1x or DAI is used, then the workaround is to add the nmsp attachment suppress command at the interface level of all switch ports. This stops ARP snooping from being enabled on the ports.
On booting a switch with a QoS policy attached to one or more Etherchannel members, a warning message is displayed for each member in the channel starting from the second member. No functional impact.
The switch, running IOS XE 3.3.1, always sends out the Web RADIUS Authentication request to the RADIUS server in clear text Password Authentication Protocol (PAP) even if the switch is configured for Challenge Handshake Authentication Protocol (CHAP).
Multicast traffic is not routed between vlans. The “rep ri” column will show “0” for the affected multicast groups. Also, the output of the show platform table-manager database resource_type 21 | count F0 command will show more than 3000.
The workaround is to connect to the WEB authentication SSID, open a WEB browser, close the browser, change the device's SSID settings to disable Auto-login, and then re-open the browser. The client should then WEB authenticate successfully.
When the ambient temperature of the switch changes and the fan has to adjust accordingly, the RMP fan values programmed in the MCU may be different than those read from the fan. As a result, this intermittent error message occurs.-Traceback= 190BA74z 182D4C8z 5E68CD5z 5E68B63z 55817EBz 55815D7z 558154Dz 5580E60z 5580444z 55802CAz
When the Ethernet management port receives a frame whose destination MAC address is not FA1, it does not drop the traffic. Instead, the port uses the vrf mgmtVrf routing table to route the traffic back.
When a policy with priority and a policer is attached to a range of interfaces on an uplink, in some scenarios, any change made to the policer rate causes the policy to be unprogrammed on one or more ports.
The DHCP snooping database agent fails to start while changing the DNS entry that the URL pointed to or when restarting the DHCP server. To avoid this issue, use another file transport mechanism like SCP or TFTP.
If you copy and paste several wireless configuration lines into the configuration, the system drops the first few characters from every other line. The number of characters dropped appears to be related to how long the command takes to execute. The issue does not occur on non-wireless configuration lines.
Multicast traffic travels on the WLAN-mapped VLAN rather than on the AP-group mapped VLAN when an AP is placed in an AP group where VLAN is overridden for the SSID and a client associates with the AP that is broadcasting this SSID.
