Configuring Cisco IOS switches for Cisco VOIP phones

Some Cisco switches, such as our Catalyst 3560 series, have Smartports which can be configured via the switch’s web interface to have roles. These roles provide the ports with typical settings for network security and QOS. If your switch doesn’t have Smartports these are Cisco’s recommended settings for each switch interface which is supporting a Cisco VOIP phone. It is taken in the content of interface fa0/1

Code block

interface FastEthernet0/1
   switchport access vlan 14
   switchport mode access
   switchport voice vlan 5
   switchport port-security maximum 2
   switchport port-security
   switchport port-security aging time 2
   switchport port-security violation restrict
   switchport port-security aging type inactivity
   macro description cisco-phone
   auto qos voip cisco-phone
   spanning-tree portfast
   spanning-tree bpduguard enable

You’ll need to change the access VLAN ID and voice VLAN ID to relate to your own PCs VLAN and voice VLAN.
