•Device Manager—An easy-to-use web interface that offers quick configuration and monitoring capabilities. Using a web browser, you can access Device Manager from anywhere in your network.
•Nine-member stacks—Up to nine switches can participate in a switch stack. All switches must be running the same feature set.
•Cisco Universal Power Over Ethernet (Cisco UPOE) feature—Sources up to 60 W of power (2X 30W) over both signal and spare pairs of the RJ-45 Ethernet cable based on IEEE 802.3at standards. It automatically detects Cisco UPOE-compliant power devices and negotiates power up to 60 W by using Layer 2 power negotiation protocols, such as Cisco Discovery Protocol (CDP) or Link Layer Discovery Protocol (LLDP). (Catalyst 3850 UPOE switches).
•Wireshark—A packet analyzer program that supports multiple protocols and presents information in a text-based user interface.
•Service Discovery Gateway feature—Enables multicast Domain Name System (mDNS) to operate across Layer 3 boundaries by filtering, caching, and redistributing services from one Layer 3 domain to another. This feature enhances Bring Your Own Device (BYOD).
•Critical Voice VLAN support—Puts phone traffic into the configured voice VLAN of a port if the authentication server becomes unreachable.
•Multicast Fast Convergence with Flex Links Failover feature—Reduces the convergence time of multicast traffic after a Flex Links failure.
•Client Count per WLAN—You can configure client limits per WLAN, per AP per WLAN, and per AP per Radio. The number of clients that you can configure for each WLAN depends on the platform that you are using.
•802.11w Support—Support for the 802.11w standard as defined by the Management Frame Protection (MFP) service. Disassociation, Deauthentication, and Robust Action frames increase Wi-Fi network security by protecting the management frames from being spoofed.
•Wi-Fi Direct Client Policy—Devices that are Wi-Fi Direct capable can connect directly to each other quickly and conveniently to do tasks such as printing, synchronization, and sharing of data. Wi-Fi Direct devices may associate with multiple peer-to-peer (P2P) devices and with infrastructure wireless LANs (WLANs) concurrently. You can use the controller to configure the Wi-Fi Direct Client Policy, on a per WLAN basis, where you can allow or disallow association of Wi-Fi devices with infrastructure WLANs, or disable Wi-Fi Direct Client Policy altogether for WLANs.
•Assisted Roaming—The 802.11k standard allows clients to request neighbor reports containing information about known neighbor access points that are candidates for a service set transition. The use of the 802.11k neighbor list can limit the need for active and passive scanning. The assisted roaming feature is based on an intelligent and client-optimized neighbor list.
•Support for IPv6 wireless clients—Client policies can have IPv4 and IPv6 filters.
•Support for 802.11ac module—The 802.11ac radio module, which is based on the IEEE 802.11ac Wave 1 standard, is available on the Cisco lightweight access points.
The 802.11ac module provides enterprise-class reliability and wired-network-like performance. The 802.11ac module supports three spatial streams and 80 MHz-wide channels for a maximum data rate of 1.3 Gbps. The 802.11ac standard is a 5-GHz-only technology, which is faster and a more scalable version of the 802.11n standard.
•Application Visibility (AV)—Classifies applications using deep packet inspection techniques with the Network-Based Application Recognition (NBAR2) engine and provides application-level visibility into Wi-Fi networks.
•Flow Control—Provides shim layers between wireless controller module (WCM) and Cisco IOS for a reliable interprocess communication (IPC). Every component in WCM has a dedicated channel. There is no configuration of flow control from CLI. You can monitor the flow control for any channel.
–Manage Rogue devices—The controller continuously monitors all the nearby access points and automatically discovers and collects information on rogue access points and clients. When the controller discovers a rogue access point, it uses the Rogue Location Discovery Protocol (RLDP) to determine if the rogue is attached to your network. For more information about managing rogue devices, see the "Managing Rogue Devices" section in the System Management Configuration Guide.
–Classify rogue access points—The controller software enables you to create rules that can organize and display rogue access points as Friendly, Malicious, or Unclassified. For more information about classifying rogue access points, see the "Classifying Rogue Access Points" section in the System Management Configuration Guide.
–wIPS—The Cisco Adaptive wireless intrusion prevention system (wIPS) continually monitors wireless traffic on both the wired and wireless networks and uses network intelligence to analyze attacks and more accurately pinpoint and proactively prevent attacks in the future. You can configure an access point to work in wIPS mode if the access point is in the Monitor or Local mode.
–Radio Frequency Grouping—A radio frequency (RF) group is a logical collection of switches that coordinate to perform radio resource management (RRM) in a globally optimized manner to perform network calculations on a per-radio basis. An RF group exists for each 802.11 network type. Clustering switches into a single RF group enables the RRM algorithms to scale beyond the capabilities of a single switch.
Question We run asr9001 with XR 6.1.3, and we have a very long delay to
login w/ SSH 1 or 2 to the device compare to IOS device. After
investigation, the there is 1s delay between the client KEXDH_INIT and
the server (XR) KEXDH_REPLY. After debug ssh serv...
Introduction The purpose of this document is to demonstrate the Open
Shortest Path First (OSPF) behavior when the V-bit (Virtual-link bit) is
present in a non-backbone area. The V-bit is signaled in Type-1 LSA only
if the router is the endpoint of one or ...
Hi, I am seeing quite a few issues with patch install and wanted to
share my experience and workaround to this. Login to admin via CLI, then
access root with the “shell” command Issue “df –h” and you’ll probably
