Software-Defined Access (SD-Access)

HelloWith the vEdges as a Fusion node, it was necessary to manually change the MTU to 1504 on the main interface (or 1496 on the sub-interfaces) to allow for the dot1q tag to the border node.With cEdges however, things just magically seem to work wit...

  Hello everyone, I'm encountering an issue during the installation of Cisco DNA Center on my server. Although all the necessary system requirements (CPU, RAM, storage, etc.) are met, the installation process gets stuck at the following step: FAILED ...

C9200 supports only 4 VNs as documented in the datasheet. Is this limitation applies to the whole SDA Fabric? I mean: If i am using only 9200 in my network, but i have different sites (all under one DNA Center): will i be limited to only 4 VNs across...

Thank you for your reply. I am having trouble with my user VN client being unable to communicate with the DHCP server.I'm using Catalyst Center 2.3.7.9 to build SDA fabric.The DHCP server is located outside the SDA fabric and connected via FusionSW.O...

Hi AllI need to move some switches into the new fabric zone. To my knowledge, the only way to do this is to remove the devices from inventory and re-add them via the discovery procedure using the switch's IP address.I've tried to use the "Assign to s...

Hi,Is there a limit of how many extended nodes or policy extended nodes are supported per fabric site? I noticed that with the largest Catalyst Centre appliance that 1200 fabric devices are supported per site, are extended nodes included in this numb...

Hi there, We have standard SDA design with a fabric site including 2 border nodes with some intermediate nodes and edge nodes connected behind. The problem is we have one border node configured as anywhere and the other one as external. We plan to co...
