Switch Recommendations
You can create a switch port template for use when you configure any switch port for connection to an access
point. This template should add all the baseline security and resiliency features of the standard desktop
template. In addition, when you attach the access point to a Cisco Catalyst 3750 or 3850 Switch, you can
optimize the performance of the access point by using Multilayer Switching (MLS) QoS commands to limit
the port rate and to map Class of Service (CoS) to Differentiated Services Code Point (DSCP) settings.
Any traffic that is not required by WLAN clients should not be sent to an access point. A template should
be designed in such a way that it helps to create a secure and resilient network connection with these features:
• Return Port Configurations to default— Prevents configuration conflicts by clearing any pre-existing
port configurations.
• Disable Dynamic Trunking Protocol (DTP)— Disables dynamic trunking, which is not needed for
connection to an access point.
• Disable Port Aggregation Protocol (PagP)— PagP is not needed for user-facing ports.
• Enable Port Fast—Allows a switch to quickly resume forwarding traffic if a spanning tree link goes
down.
• Configure Wireless VLAN—Creates a unique wireless VLAN that isolates wireless traffic from other
data, voice, and management VLANs. This isolates traffic and ensures greater control of traffic on the
wired infrastructure.
• Enable Quality of Service (QoS); do not trust port (mark down to 0)—Ensures appropriate treatment
of high-priority traffic, including softphones, and prevents users from consuming excessive bandwidth
by reconfiguring their PCs. Please refer to the mobility design guide for more details, at: http://

Vocera badges use Voice marking. The following QoS information can be used to filter Vocera packets:
• IP Precedence (Class Selector) = 5 (101 binary)
• DSCP = Expedited Forwarding (EF) or 46 (101110 binary)
• IP ToS = 0xB8 (10111000)
Inline Power Switches can be used to provide power to access points that are capable of receiving inline
power.
