Converged Network?
A network where multiple types of traffic are all under one network
Saves a lot of money
What is a Cisco Borderless Network?
Allows organizations to connect anytime anywhere with any type of secure device
easily
Borderless switched networks are what 4 things?
Hierarchical
Modular
Resilient
Flexible
Converged networks that are part of organization have 3 parts...what are they?
Core - The center
Distribution - connection to the core
,Access - Switches are used to connect to the distribution and give access to the
users
Switched LANS allow for what?
Flexibility
traffic management
Features like: QoS, security, wireless
Fixed vs modular vs stackable switch form factor?
Fixed - number of ports and abilities is set, no changes
modular - extra ports and other things can be added later
stack-able - switches are stacked a connected by cables to operate as one big
switch
How does a switch learn what devices are on a network?
It builds a table called a MAC address or CAM table
This table saves the device port.
What does a switch do when it gets a frame that is not in the CAM table?
The switch floods all known ports except the one that they got the frame from.
The correct port will accept the frame.
Store and forward vs cut-through?
, - gets the entire frame and finds the CRC, if valid the frame is forwarded
- forwards the frame before it has been fully received. It at least reads the
destination address
Collision domain?
all ports belong to the same collision domain
all ports have a collision domain of their own
How doe switches help alleviate network congestion? 3
segment the collision domains by port
provide full duplex communication
buffer large frames
Switch Boot Sequence? (5)
1. POST
2. Run boot loader software
3. Boot loader does CPU initialization on a low-level
4. initializes the flash file system
5. Loads the IOS operating system
What are the steps required to find a IOS image?
- Tries to boot with info already available in BOOT environment
