Hi, I have a working location with single 9300X working as FIB - i.e. it runs edge, contorl, border and also embedded WLC functionality. The fabric is working good. But now I need to change the Loopback0 IP address (due to global network renumbering)...
Hello, I have a question regarding the migration of an existing 9800 WLC within an SDA Fabric. Our current setup includes: - 2 x 9800-40 WLCs (In SSO) configured as Primary Managed AP Locations, - 1 x C9800-CL configured as Secondary Managed AP Locat...
Hello experts, I have a question regarding SDA Wireless, we have 2 9800 in our fabric, and we have a remote site with some 2800 APs but non fabric.Is it possible to connect these non-fabric APs to the fabric 9800? We need to have the fabric SSID’s on...
Hello everyone,I am planning a Cisco SD-Access deployment with the topology shown in the attached diagram.Before Catalyst Center can discover and add the border device to its inventory, IP connectivity must be established between Catalyst Center and ...
Resolved! SDA Wireless Client Roaming
Hello,I am trying to clarify a little doubt. Considering that I am using SDA with LISP Pub/Sub Model, when a client roams (either Wired or Wireless), is the CP going to publish the L2 and L3 Client address+ new RLOC entries to all subscribed nodes (t...
Cisco DNA Center Version 2.3.3.7-72328 We have a use case where we'd like to swap a C9500-24Y4C for a C9500-48Y4C. Is this possible in DNAC, or would the new 48 port switch need to be added to the inventory/fabric site, assigned the fabric role[s] be...
Hello,Why is IS-IS level-1 not used in SDA, instead of level-1-2? Why on an SDA site we need to mantain a level-2 adjacency and database too, if we can just have everything on the same area? In what production scenario do we benefit from level1-2 on ...
Is there any difference between a single-node DNAC deployment and a three-node DNAC cluster, apart from high availability (HA), which I understand requires a three-node cluster?What other differences or additional capabilities should I be aware of be...
Resolved! SDA ARP Handling
Hello, I am just trying to understand how ARP in the overlay is handled by SDA. I get all the operation an order of operations. But I have a doubt:When the endpoint sends the ARP request and the Edge Node intercepts it, and then the Edge Node sends t...
