How to Scale for Service Provider Wi-Fi 2 Compliance is supported on the Standard, Professional virtual appliance (OVA) and the Gen 2 appliance only. It is not supported on: Express, Express Plus, OVAs that have been resized to Standard or Professional. If you are running Prime Infrastructure on an unsupported OVA or physical appliance and want to enable Compliance, you must perform a fresh install of the 3.4 Standard or Professional OVA or Gen2 appliance, then use backup/restore to migrate data from your old server to the new server. See Enabling Compliance Services in the Cisco Prime Infrastructure 3.4 Administrator Guide . 3 Changing Clients are wireless users who are roaming across APs or disassociating and associating to APs. 4 The NetFlow rate depends on the number of unique clients in the flows. The supported NetFlow rate is also based on the translated number of hourly host records (or unique combinations of server/client and applications) per day. 5 If the Compliance violation for the Professional virtual appliance exceeds 80000, the compliance job will not show any data. Note Supported Scale for PnP Provisioning: • Maximum number of devices per profile: 100 • Maximum number of Simultaneous Deployments per APIC-EM limitation : 50 (Threads) How to Scale for Service Provider Wi-Fi The following table lists the Service Provider Wi-Fi parameters. Table3:ScalingforServiceProviderWi-Fi Parameter Maximum Supported Number of APs 20,000 Number of clients 100,000 Sustain trap rate 300/sec Burst trap rate 400/sec for 10-minute duration How to Scale for Operations Center When using Operations Center, we recommend that you: • Use the Standard OVA installation option. • Ensure that your network is providing the following performance levels between Operations Center and its managed devices: • Bandwidth—250 Kbps • Latency—up to 5 ms. This is not a hard requirement, but Operations Center will only be as fast as its slowest managed instance. The higher the latency, the slower the overall performance. Use the Network Latency column on the Operations Center Manage & Monitor Servers page to spot managed instances that may be acting as bottlenecks. • Ensure all instances managed by Operations Center are running Prime Infrastructure 3.4. Cisco Prime Infrastructure 3.4 Quick Start Guide 6

How to Scale for Data Center To help you roll out new versions of Prime Infrastructure at your own pace, Operations Center always supports management of instances of both the current and the very last version of Prime Infrastructure (also known as “N-1 management”). For example: If you upgrade your Operations Center management server to 3.4, you can use that server to continue managing Prime Infrastructure 3.3.x instances, as well as upgraded 3.4 Prime Infrastructure instances. Note Make sure that you do the following when you are upgrading the Operation Center: • Remove the managed instances before upgrading the Operation Center. • Upgrade the Operation Center. • Re-add the managed instances. The following table lists the Operations Center scaling parameters. Table4:ScalingOperationsCenter Operations Center Parameter Maximum Supported Number of managed instances 10 Number of managed virtual domains 100 Concurrent GUI clients 100 See Physical Appliance Options, on page 3 for physical appliance options and the table under the section How to Scale Prime Infrastructure, on page 4 for installation option scaling information.
