Introduction
In this document we will see how Packet Flows Between Cisco PPPoE Access Point and PPPoE server. As mentioned in the previous document "
Cisco Service Provider Wi-Fi - PPPoE Feature Support", Cisco has come up with bunch of features those were developed to help Service Provider in deploying large network in public area and named it as SP Wi-fi but it does not mean that it is limited to Service Providers. Anybody can use SP Wi-Fi features, it all depends on company’s network and requirements.
(AP was not configured with MTU under PPP - configuration and supports default -1500)
From server for Access Point’s Magic Number
From PPPoE Server – server sending MTU as – 1492 and magic number
From AP because it supports the feature but higher MTU
PPPoE server again sending request with revised MTU because higher value will be selected
Now Access Point acknowledges it
Note – Same way all the supported features of LCP will be negotiated.
From AP for IP address and DNS
From PPPoE server – providing IP Address and DNS IP to the AP
The main features supported in Release 1.0 include:
• Controlling, securing, and differentiating services through intelligent policies embedded directly in the network or received through open and standards-based control interfaces to the basic service set (BSS)
• Customizing service convergence with zero-touch provisioning across customized networks
• Authenticating and authorizing subscribers using Dynamic Host Configuration Protocol (DHCP), RADIUS-based authentication, web logon, Wireless Internet Service Provider roaming (WISPr), MAC address, and IP address
• Controlling and accounting for per-subscriber and per-service use for postpaid and prepaid billing
• Validating high availability under high scale for:
– Number of access points per controller
– Subscriber count
– Call rates
– Load balancers
