routing at the access layer
Building-distribution considerations
Distribution layer require wirespeed
Aggregation point for access layer switches
High-speed connectivity to campus core
Redundant connections to the campus core layer
Stateful Switchover (SSO) and Nonstop Forwarding (NSF)
High availability, quality of service (QoS), and policy enforcement
Campus core considerations
interconnecting three or more buildings
High-speed ports required to aggregate the building distribution layer.
least two switches Core
Server farm considerations
Determine server placement in the network
All server-to-server traffic should be kept
within the server farm module
For large network designs, consider placing
the servers in a separate data center
Consider using network interface cards
(NIC) in servers that provide at least two
ports
For security, place servers with similar
access policies in the same VLANs
limit interconnections between servers in
different policy domains using ACLs on the server
farm’s multilayer switches.

processor resources to accommodate a
large STP processing load.
Data center core layer design
best practices
Use the separate cores (that is, the campus
core and the data center core) to create
separate administrative domains and
policies (for example, QoS policies and
ACLs)
