Chapter 2 Switch Configuration
Two common network designs are currently employed at the venues:
•
A two-layer design, where the Access and Distribution layers are collapsed
•
A three-layer design, where a separate Access layer of switches is used for
aggregating endpoints (shown as Option 2 in
These two designs require a slightly different configuration of the switches to
enable CNR as the DHCP server for the Cisco StadiumVision network.

Configuration
In the two-layer network design (represented by Option 1), the Cisco Catalyst
3750-E switch that is directly connected to the endpoint devices (e.g., DMPs, IP
Phones), is configured for DHCP snooping at a global level and for each of the
applicable VLANs.

Also, the VLAN interface is configured with an “ip helper-address” of the CNR
