Cisco Catalyst 3850 Series Switches Ideal for Fast Connectivity

With the current release of a picture based Virtual Controller it was inevitable as I would like to think before Cisco released a switch/WLC combo solution and now they have done recently that by releasing the Cisco 3850 series. 

Having had a speedy read the specifications it does without a doubt look intriguing, anyway there is a limitation to uncovered as a primary concern - The 3850 just supports 50 Access Points for each switch entity. This implies even in its stacked form (you can stack up to 4) this constraint still applies! I’m sure Cisco have their explanations behind this however here are my thoughts as why this might be: 

1) Having to complete the errands of both a switch and a WLC in one bit of hardware it may be the case that taking care of in excess of 50 access points can possibly be a lot for the CPU to manage. 

2) The Catalyst 3850 is a perfect answer for when there is only a solitary switch or switch stack in the topology of the network. Exposing as a primary concern that the maximum length for an Ethernet cable is 100m, I guess it is far-fetched that there would be in excess of 50 access points deployed inside this 100m cable run range. 

3)Cisco may permit the hardware to be licensed upgraded to manage more APs in a later IOS release (as it did as of late with the 2504 controller which was upgraded from a most extreme capacity of 50 APs to 75). 

Benefits: Converged Wireless plus Wired Access

The cisco catalyst 3850 series switches are the primary stackable access switch platform that empowers wired in addition to wireless administrations on a solitary Cisco IOS XE Software-based platform. With this, Cisco has spearheaded a large group of rich abilities, for example, high accessibility dependent on stateful switchover (SSO) on stacking, granular QoS, security, and Flexible Netflow (FNF) across wired and remote in a consistent manner. 

Likewise, the wired in addition to wireless highlights are packaged into a solitary Cisco IOS Software picture, which lessens the quantity of software pictures that clients need to qualify/ensure before empowering them in their network. The single console port for command line interface (CLI) management decreases the quantity of touch focuses to oversee for wired in addition to wireless administrations, in this manner simplifying network operations, disentangling network activities, and bringing down the TCO to manage with the infrastructure. 

United wired in addition to wireless improves wireless bandwidth transmission over the network as well as the scale of wireless deployment. Each 48-port Cisco 3850 gives 40 Gbps of wireless throughput (20 Gbps on the 24-port model). This wireless capacity increments with the quantity of individuals in the stack. This ensures the network can scale with current wireless bandwidth transmission capacity necessities, as directed by IEEE 802.11n-based access points and with future wireless guidelines, for example, IEEE 802.11ac. Also, the Catalyst 3850 circulates the wireless controller functions to accomplish better adaptability. Every Cisco 3850 switch/stack can work as the wireless controller in two modes: 

Mobility Agent (MA)

This is the default mode wherein the cisco catalyst 3850 series switches ships. In this mode the switch is equipped for ending the CAPWAP tunnels from the access points and giving wireless connectivity to wireless clients. Keeping up wireless customer databases and configuring and implementing security and QoS policies for wireless customers and access points can be upheld in this mode. No extra license on head of IP Base is required to work in the mobility agent mode. 

Mobility Controller

In this mode, the Cisco 3850 switch can play out all the mobility operator assignments notwithstanding mobility coordination, radio resource management (RRM), and Cisco CleanAir® coordination inside a mobility subdomain. The mobility controller mode can be empowered on the switch CLI. A halfway found Cisco 5508 Wireless LAN Controller (WLC 5508), Cisco Wireless Services Module 2 (WiSM2) (when running AireOS Version 7.3), and Wireless LAN Controller 5760 can likewise play out this job for bigger deployments.

With mobility specialists situated in the wiring storage rooms giving 40 Gbps of wireless for each switch (n x 40 Gbps for a stack of switches) and mobility controllers dealing with a portion of the central wireless functions, the met get to based wireless deployment gives top tier adaptability to wireless and altogether improved wireless throughput.

FNF (Flexible NetFlow)

Full visibility into the wired in addition to wireless traffic is accomplished as a result of the access point Control and Provisioning of Wireless Access Points (CAPWAP) tunnel end on the switch. This distinguishes clients and client traffic flows s to recognize expected assailants and make remedial move at the entrance layer before the assault infiltrates further into the system. This is accomplished utilizing FNF, which screens each and every stream entering and leaving the switch stack for wired and wireless clients. It additionally distinguishes the top wired/wireless talkers and implement suitable bandwidth transfer capacity provisioning policies.
