LAN Base, IP Base and IP Services these 3 features are available with all Cisco Catalyst 3850 models. What are their features?
2. The IP Base feature set provides entry-level enterprise services in addition to all LAN Base features, with 1K VLANs. IP Base also includes the support for wireless controller functionality (mobility agent and mobility controller role; additional access point license required for mobility controller role), routed access, smart operations, FNF, and so on.
3. The IP Services feature set provides full enterprise services that include advanced Layer 3 features such as EIGRP, OSPF, BGP, PIM, and IPv6 routing such as OSPFv3 and EIGRPv6. All software feature sets support advanced security and MQC-based QoS.
The Cisco Catalyst 3850 Series Switches with LAN Base feature set can only stack with other Cisco Catalyst 3850 Series LAN Base switches. The same applies to IP Base and IP Services as well. A mixed stack of LAN Base switch with IP Base or IP Services feature set is not supported.
The 12-port and 24-port SFP+- and SFP-based models as well as the 48-port SFP+ model can only be ordered with IP Base or IP Services licenses. Therefore, in order to stack with LAN Base models, they need to be configured in LAN Base mode from the CLI.
Customers can transparently upgrade the software feature set in the Cisco Catalyst 3850 Series Switches through Cisco IOS Software CLI using the right to use (RTU)-based software upgrade process. Software activation enables the Cisco IOS Software feature sets. Based on the license’s type, Cisco IOS Software activates the appropriate feature set. License types can be changed, or upgraded, to activate a different feature set.

Top 10 Cisco Wireless “Good to Know”
1) Controller interface vlan tagging, native vlan 1
Cisco Switches by default do not tag the native vlan. Also by default, the native vlan is 1, therefore vlan 1 is untagged.
When establishing a trunk to a Cisco Wireless LAN Controller, it's important to be aware of how tagged vs untagged are identified.
(4400-A) >show interface summary
Interface Name Port Vlan Id IP Address Type Ap Mgr Guest
--------------- ---- ---------- -------------- ----- ------ -----
ap-manager 1 untagged 184.108.40.206 Static Yes No
management 1 untagged 220.127.116.11 Static No No
When going through a WLC's initial startup wizard, if untagged for the Management Interface’s vlan is desired, enter '0' (zero) when prompted for the management interface's vlan, as this is equivalent to 'untagged':
Welcome to the Cisco Wizard Configuration Tool
Use the '-' character to backup
Would you like to terminate autoinstall? [yes]:
Management Interface VLAN Identifier (0 = untagged): 0
2) AP Image Names: w7 vs w8
ap image names:
w7 = standalone
w8 = lightweight
Lightweight/controller based/capwap/lwapp image:
Cisco IOS Software, C1130 Software (C1130-K9W8-M), Version 12.4(23c)JZ, RELEASE SOFTWARE (fc1) c1130-k9w8-mx.124-23c.JZ
Cisco IOS Software, C1140 Software (C1140-K9W7-M), Version 12.4(21a)JY, RELEASE SOFTWARE (fc1)c1140-k9w7-mx.124-21a.JY
3) AP Part Numbers: LAP vs AP
Most Cisco Access Points are available with two part numbers.
LAPxxx = shipped new from manufacturing with lightweight image
APxxx = shipped new from manufacturing with autonomous image
Same physical hardware.
Same physical ap's, the first is shipped with a lightweight image, the second with an IOS image:
Most AP's can be converted between both modes.
4) Wireless LAN Controller DHCP Handling
Wireless Lan Controllers perform 'dhcp proxy' by default. The ‘Dhcp Server’ IP Address configured on controller interfaces acts the same way as an 'ip helper' statement on a Cisco router.
With this configuration in place, an IP Helper statement on the wireless clients’ default gateway router is not necessary.
DHCP Proxy can be configured via the WLC’s GUI in 6.x and 7.x code (Controller -> Advanced -> DHCP).
Earlier code requires CLI access for configuration:
(WLC) >show dhcp proxy
DHCP Proxy Behaviour: enabled
(WLC) >config dhcp proxy disable
(WLC) >show dhcp proxy
DHCP Proxy Behaviour: disabled
5) Lightweight AP modes: Local vs H-Reap (FlexConnect)
Local mode Access Point: tunnels all traffic to controller, controller responsible for tagging packets and putting them on the wired network, AP's switchport configured in access mode/non trunk.
H-Reap mode Access Point: ap's function similarly to standalone ap's, tag their own traffic, AP's switchport configured as trunk. Vlan tagging requires configuration on each H-Reap mode AP (Via the controller’s Gui).
*H-Reap was renamed to 'FlexConnect' in 7.2 code.
6) Legacy Access Points End of Support
1500 Series, LAP-1505, LAP-1510: Last supported in 4.2.M controller code.
1000 Series, AP1010, AP1020, AP1030: Last supported in 4.2 controller code.
1120/1230 Series, 1121, 1230, etc. Last supported in 7.0 code.
1130, 1240, 1520. Last supported in 8.0 code (no support in 8.1 and later).
Software Release Support for Access Points
These Access Points will not join a controller running code later than supported.
7) AP console settings
•8 data bits
•1 stop bit
*********No hardware flow control******
These are the same settings for other Cisco devices. It is essential that AP's console session have flow control disabled. Most other Cisco devices will tolerate this setting if not disabled, but AP's will not. The result is typically no display and/or keyboard response.
8) WLC Dynamic Interfaces, Does it Route?
Those familiar with Cisco routing and switching may get the impression that Wireless Lan Controllers have routing capability. This may seem apparent due to the fact that multiple dynamic interfaces with ip addresses may be configured. WLC's do not route.
The ip addresses assigned to the dynamic interfaces are not used for client traffic passing through the controller.
Dynamic interfaces' IP addresses primary functions are:
+ Referenced as Giaddr for DHCP Proxy (relay)
+ Multicast. For wireless multicast receivers connected to local mode ap's, if the controller has IGMP snooping enabled, it will proxy/spoof IGMP reports to the wired network using the client's corresponding dynamic interface IP address. If IGMP snooping on the controller is disabled, client IGMP reports are forwarded unmodified to the wired network.
+The IP address is checked when you do an intercontroller roam, so that the WLC knows if you did a L2 or L3 roam, and whether to anchor your traffic or to pass the MSCB entry to the new WLC.
By default, multicast traffic is not forwarded by Wireless Lan Controllers for local mode ap's.
A common source of confusion is that Autonomous Mode AP's will forward multicast just as they would unicast, so no configuration is required. In the instance of Autonomous AP's being converted to Controller Based/Lightweight, multicast will no longer work until configured on the controller.
Since Controller based H-Reap mode ap's forward their own traffic, multicast will behave as if the AP were a standalone AP, and no controller configuration is required.
10) Anchored Wlans. Where does authentication occur?
For Layer 3 authentication, e.g. Web Auth, authentication handling occurs on the Anchor Controller.
For Layer 2 authentication, e.g. 802.1x, authentication handling occurs on the Foreign controller.
A: Regarding point 8 about the dynamic interfaces configured on the WLC, it is perhaps worth adding that they can act as source addresses when clients try to obtain an ip address via DHCP. This document explains more: http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a00805e7a24.shtml
B: You may want to add what else the dynamic-interface IP comes to play for. The IP address is checked when you do an intercontroller roam, so that the WLC knows if you did a L2 or L3 roam, and whether to anchor your traffic or to pass the MSCB entry to the new WLC.
C: A note on the AP support - I believe that some APs will join WLCs with code 8.1 but new features won't be supported such as AVC on local FlexConnect due to hardware limitations.
Note The Cisco 1040 Series, 1140 Series, and 1260 Series access points have feature parity with Cisco Wireless Release 8.0. Features introduced in Cisco Wireless Release 8.1 and later are not supported on these access points.

Cisco HDX Manages Performance on Crowded Wi-Fi Networks Wi-Fi traffic is everywhere.
More users-employees, customers, and guests alike - are connecting to the network. Most of these users carry multiple Wi-Fi devices and many devices support only wireless connectivity. All this leads to lots of very dense Wi-Fi traffic in the air.
And with the introduction of 802.11ac Wave 2 technology, networks are only going to get more crowded. That’s why Cisco has enhanced its High Density Experience (HDX) suite of solutions, which automatically manages the airwaves and improves Wi-Fi performance.
Now, available on Cisco’s Indoor Access Points the Cisco Aironet 3800 and 2800 Series and the Cisco’s Outdoor Access Points the Cisco Aironet 1570 and 1560 Series Outdoor Access Point,
HDX is regularly updated with new features that alleviate high-density network strain and improve user experiences as 802.11ac and other trends load the airwaves with more traffic.
Managing Your Airwaves
• Alleviate network strain when large volumes of client devices contend for access point connectivity
• Improve Wi-Fi throughput and spectrum efficiency
• Prevent unnecessary Wi-Fi disconnections
• Enable access points to quickly change channels to mitigate interference or narrow bandwidth instead of abandoning the entire channel
• Allocate air time to specific user groups
Simplifying and Automating RF Tasks Below are some of the more recent HDX feature enhancements:
• Enhanced Optimized Roaming: If performance degrades as Wi-Fi users move, this feature intelligently steers clients to an access point with a stronger signal - without interrupting the connection.
• CleanAir for 160-MHz Channels: Proactive protection against RF interference with spectrum scanning, source identification, and remediation that now works across 160-MHz channel widths.
• ClientLink: Cisco’s patented beamforming technology that improves performance of 802.11ac clients as well as 802.11a/g/n legacy clients.
• Dynamic Bandwidth Selection (with FlexDFS): Continually analyzes and selects the best channel width for use in current conditions. If radar is detected on part, but not all, of the frequency, the access point can narrow the serving channel from 160 to 80 to 40 or 20 MHz, rather than moving entirely to a new frequency, enhancing spectrum efficiency.
• Event-Driven Radio Resource Management (ED-RRM): Rapidly changes channels to avoid interference, doing in seconds what previously could take minutes. IT can also set thresholds to determine when traffic automatically moves to a clear or less busy channel.
• HDX Air Time Fairness (ATF): Simplifies Wi-Fi traffic management by enabling network administrators to allocate specific percentages of airtime to heterogeneous groups of clients or customers.
More about the Cisco HDX Solution
HDX is a broad and comprehensive suite of solutions delivered in the Cisco Aironet 2700 and 3700 Series access points, consisting of both hardware and custom application-specific integrated circuits (ASICs) and software elements to provide optimal performance in high-density WLAN environments.
Cisco developed HDX to address the increasing proliferation of both wireless networks and wireless devices (such as smartphones, tablets, and PCs) carried by individual users - creating increased traffic. HDX directly addresses the expectations of both network administrators and mobile device users that WLANs will continue
to “just work” despite increasingly demanding scenarios.
In brief, when designing HDX, Cisco carefully considered the ramifications of increases in:
● Access point density (public and residential)
● Co-channel and adjacent channel interference
● Inter-access point contention
● Intra-access point contention (due to more clients and increased upstream)
● Client density
● Variation in client types
Therefore, HDX is essential for WLANs operating in environments that are characterized by any of the following:
● Many clients connected to a single access point
● Many colocated access points deployed as a single WLAN with partial to full channel (frequency) overlap
● Many independent yet neighboring WLANs needing to coexist in the same spectrum
● Increased loading due to more upstream and downstream video traffic: more FaceTime and Skype traffic (bidirectional interactive apps, unified communications), more mobile app downloads, more uploading of personal content (photos, cloud/sync functions, etc.)
HDX Features Provided in the Cisco Aironet 2700 and 3700 Series
The primary features of HDX are:
● Cisco CleanAir 80 MHz
● Cisco ClientLink 3.0
● Optimized Roaming enhanced with BSS Transition Management
● Turbo performance
● Enhancement: Dynamic Bandwidth Selection (with Flexible Dynamic Frequency Selection (FlexDFS))
● Enhancement: Wi-Fi triggered Event-Driven Radio Resource Management (ED-RRM)
● Enhancement: Air Time Fairness
● RF noise reduction (available in future versions)
Each of these features is detailed in the sections that follow.
Cisco is the only equipment vendor to have the complete suite of features that make up HDX. Furthermore, it is the only equipment vendor to have a purpose-built access point with hardware acceleration that supports HDX and that is designed specifically for the high-performance challenges of 802.11ac.
