Cisco Wireless Architecture Flashcards
Three types of wireless architecture? Mik
Autonomous
Cloud-based
Split-MAC
What are the three types of split-mac architecture does Cisco offer?
Centralized (WLC)
Converge (WCM)
FlexConnect
What type of APs does a cloud-based architecture use?
Autonomous
What type of APs does a split-mac architecture use?
LAP (lightweight access point)
How does flexconnect differ from centralized architecture?
LAP can locally switch traffic if it loses its CAPWAP tunnel to the WLC.
Cloud-based architecture consist of two distinct traffic paths? What are they?
Control plane
Management traffic goes to the cloud
Data plane
End-user traffic passes thru AP
Which of the split-mac architectures is the highest performance design?
Converged
Which of the split-mac architectures is preferred for premise-based controller locations?
Centralized
Which of the split-mac architectures is preferred for data center hosted environments?
FlexConnect
What does CAPWAP stand for?
Control and Provisioning of Wireless Access Points
What are the two types of CAPWAP tunnels and what port do they use?
Control messages (UDP port 5246) Data (UDP port 5247)
By default which of the two CAPWAP tunnels is encrypted?
Control messages tunnel
Data tunnel can be configured for encryption
If data encryption is enabled for a LAP, what protects the packets?
DTLS
Datagram Transport Layer Security
How many APs and clients can a Catalyst 3650 support?
25 APs per stack
1,000 clients
How many APs and clients can a Catalyst 3850 support?
50 APs per stack
2,000 clients
How many APs and clients can a Catalyst 4500 support?
50 APs per switch
2,000 clients
How many APs and clients can a virtual WLC support?
2,00 APs
6,000 clients
How many APs and clients can a 5520 WLC support?
1,500 APs
20,000 clients
Which Meraki AP models only support n and not ac?
MR18
MR26
MR66
Which Cisco AP model supports ac Wave 2?
1850 (standard)
3700 with an optional module
List the 8 special-purpose modes that a LAP can be configured to operated?
Local Monitor FlexConnect Sniffer Rogue detector Bridge Flex + Bridge SE-Connect
What is the SE-Connect mode used for on a Cisco LAP?
The LAP dedicates its radios to spectrum analysis on all wireless channels and can be remotely connected to software like MetaGeek Chanalyzer or Cisco Spectrum-Expert.
What is the Cisco architecture that keeps the radios distributed, but collapses wireless services into the core of the switched network?
CUWN (Cisco Unified Wireless Network)
