Cisco 71642 - Manual

Note: If AP Group VLANs are configured, and an IGMP join is sent from a client through the controller, it isplaced on the default VLAN of the WLAN that the client is on. Therefore, the client might not receive thismulticast traffic unless the client is a member of this default broadcast domain. Mult...

Disable Switch VLAN IGMP Snooping IGMP snooping allows a switched network with multicast enabled to limit traffic to those switchports thathave users who want multicast to be seen while pruning the multicast packets from switchports that do notwish to see the multicast stream. In a Vocera deployment...

Multiple Controller Layer 2 Deployment Multiple controllers must all have connectivity to each other via the same Layer 2 broadcast domain. Bothcontrollers are configured for multicast as shown, using the identical access point multicast groups on eachcontroller to limit fragmentation. With the assu...

Figure 7Multiple Controller Layer 3 Deployment VoWLAN Deployments: Ciscos Reccommendations Wireless IP Telephony networks require careful RF planning. A thorough voice site survey is often requiredto determine the proper levels o...

Hospitals can have several types of wireless networks installed. This includes 2.4 GHz non−802.11equipment. This equipment can cause contention with other 2.4 GHz networks. • Wall−mounted diversity patch antennas and ceiling−mounted diversity omni−directional antennas arepopular, but keep in mind th...

(off−ACS) database to store the user names and passwords for the badges, Cisco does not recommend thispractice. Because the ACS must be queried whenever the badge roams between access points, theunpredictable delay to access an off−ACS database could cause excessive delay and poor voice quality. Wir...

Switch Recommendations Note: If you use a Cisco Catalyst 4000 Series Switch as the main router in the network, ensure that it contains,at a minimum, either a Supervisor Engine 2+ (SUP2+) or Supervisor Engine 3 (SUP3) module. The SUP1 orSUP2 module can cause roaming delays, as can the Cisco Catalyst ...

When Subnet Roaming is checked, it instructs the badge to request a new IP address after each roam. In theLWAPP environment, the infrastructure helps maintain client connectivity at Layer 3. When a voice clientmust wait for the DHCP server to respond before it is able to send or receive packets, del...

Wireless Network Infrastructure Configuration The Cisco Unified Wireless Network design and deployment guide should be followed for the overallconfiguration of your WLC(s). This section provides additional recommendations specific to Vocera®Communication Badges. Note: Changes are left unsaved if you...

Figure 10List of WLC Interfaces Create the Vocera Voice Interface Complete these steps: Click New. 1. Enter a tag name representative of your Vocera VoWLAN network in the Interface Name field. 2. Enter the VLAN number of that VoWLAN network in the VLAN ID field. 3. Click Apply and then click Edit in...

WLAN Configuration Complete these steps: Update the Radio Policy field to a value that best fits you needs. 1. Change Admin Status to Enabled. 2. Set Session Timeout to 1800. 3. Set Quality of Service to Platinum. 4. Set Broadcast SSID to Enabled. 5. Set the Interface Name to the interface created f...

Configure Access Point Detail Complete these steps: Click Detail. 1. Configure the AP Name. 2. Ensure that the access point is configured for DHCP. 3. Ensure that Admin Status is Enabled. 4. AP Mod should be set to local. 5. Enter the location of the access point. 6. Enter the controller name that t...

ORIf the telephony server is available, initiate a call with a stationary device to the badge. ♦ Continually check voice quality while you traverse the total wireless coverage area. If thevoice quality is insufficient, perform these tasks: ♦ Listen for all unacceptable changes in voice quality and t...

Audio Problems There are a few common configuration errors that can cause some easily resolved audio issues. If possible,check audio problems against a stationary (reference) badge to help narrow the problem to a wireless issue.Common audio problems include: One−sided Audio • Choppy or Robotic Audio...

Re−authentication / Session TimeoutIf configured, a session timeout triggers a re−authenticationwhich causes gaps in the voice stream (300 ms + WAN delay for 802.1x authentication). • Appendix A AP and Antenna Placement This section gives examples of both proper and improper placement of access poin...

For areas where user traffic is high (such as office spaces, schools, retail stores, and hospitals), Ciscorecommends that you place the access point out of sight and place unobtrusive antennas below the ceiling.Separation for non−diversity antennas should not exceed 18 inches. Interference and Multi...

While directional antennas can be of great value for certain indoor applications, the vast majority of indoorinstallations use omni−directional antennas. Directionality should be strictly determined by a correct andproper site survey. Whether you use an omni−directional or patch antenna, indoor envi...
