The Vocera Communications System is a breakthrough solution that enables instant voice communication when and where it’s needed—enhancing organizational productivity and customer service. Follow the steps mentioned below to configure controller to support Vocera.

CONFIGURATION STEPS:

CLI Steps:

STEP 1: Configure a separate vlan for VoIP application (always recommended)

vlan voice_vlan tag tag
ip address x.x.x.x x.x.x.x
ip default-gateway x.x.x.x
ip dhcp-passthrough
ip dhcp-override
exit

STEP 2: Configure ESSid

essid name
security-profile profile_name
vlan name vlan_name
vlan support configured-vlan-only
beacon dtim-period 1
beacon period 100
silent-client-enable
coordination-mode centralized
multicast-enable
publish-essid
exit

STEP 3: Open UDP port 5555

ip udp-broadcast upstream 5555
ip udp-broadcast downstream 5555

STEP 4: Configuring QoS

qosrule id netprotocol 17 qosprotocol none
dstport 5002
srcip x.x.x.x (vocera IP)
srcmask x.x.x.x
action forward
droppolicy tail
priority 0
avgpacketrate 1
tokenbucketrate 200
exit
