Medium-density campus design 
The medium-density campus design adds a single distribution layer to the access layer, which can be 
standalone or used as a collapsed core connected to another distribution, or other services, or perhaps 
connected to WAN router at a remote site that has grown large enough to need an aggregation layer. The 
demands in the access layer for wired ports and WLAN devices typically number in the hundreds versus the 
thousands for a large design, with requirements for less than a few groups of 50 or fewer APs. The preferred 
design strives for typical business continuity needs not requiring every redundant component offered and 
standard network capabilities. 
Campus wired distribution, wired access, and wireless 
You make choices for the wired distribution and access with a bias towards size and flexibility in order to 
accommodate the space and power requirements of medium sized installations in a way that can elastically 
expand as an organization grows. Where densities and advanced software feature capabilities are not as strong 
of a requirement, options with a more economical and common sparing preference are shown. 
The medium-density designs are equivalent to the small-site campus design with the addition of a distribution 
layer.
