After having a look at AP onboarding, let’s now take a look at how client are onboarded in Fabric-enabled Wireless infrastructure. In the below Web Diagram Sequence, we consider a SSID configured with 802.1X security mechanism. Web Sequence Diagram Detailed Step-by-Step Process Not related to SDA directly, but the first step is to perform 802.11…
Web Sequence Diagram The Web Sequence Diagram below show the step-by-step process to get Access Point in “SDA mode”. Steps are detailed below. Detailed Step-by-Step Process AP is powered through PoE/Power-brick or Power Injector and switchport is going to Up/Up state as the AP boot up; At this step, two options are available based on…
As any Network/Wireless Engineer we tend to automate more and more actions in order to save time (and money?), so I decided to dig deeper and deeper into Python, but …
What is Peer-2-Peer blocking? Peer-2-peer (P2P) blocking is a security feature allowing an administrator to drop (or force to switch upstream) data traffic between clients associated to the same WLAN. P2P is mostly deployed in Guest WLANs where you don’t want your clients to be able to communicate between each others. This settings can be…
The Cisco ISR 1000 Series router can include (depending on the model) an internal Access Point to provide Wireless connectivity to users. To access the Access Point and configure the network so the AP can reach the WLC, here is the procedure: Check to which subslot the AP is mapped : Router#show hw-module subslot all…
As described in the blog post about Anycast RP, we can take advantage of MSDP to have a load-balancing & Failover mechanism between RP, but still, we need to configure the RP address on each and every device taking part of the multicast infrastructure. To automate this repetitive (and boring) task, Cisco has developed Auto-RP,…
MSDP (Multicast Source Discovery Protocol) has been developed to exchange information about sources of multicast traffic between multiple BGP Domain. It can also be used as a key protocol allowing us to have two or more RPs to share the load and provide redundancy in case of RP failure. Key Concept Two or more RPs…
In this post, we will see how to configure an IOS autonomous access point to act as 802.1X supplicant. For the setup, I have a : 3502i AP – 15.3(3)JD16 (8.3.143.0) 3750G switch – 12.2(55)SE9 ISE appliance 2.2 ISE Configuration Add the AP as Network Devices : Administration > Network Resources > Network Devices >…
