Hello, Is there a means to deny traffic between endpoints belonging to the same Scalable Group?  This for the obvious reason to prevent lateral movement between SG members.  I am looking for the lookalike of ACI's 'Intra EPG isolation'.  

Hi guys,The Edge devices in SDA had only one fabric uplink due some reasons.So now I have to deploy additional more link to protect against physical link failure.But I consider the method, manually configure connected IP and IS-IS or re-provisioning ...

We are looking at integrating our WLC into DNA and just making sure we have all the information before we progress with the process. Are you still able to manage the WLC manually after it has been provisioned by DNA or is DNA the only way to manage a...

Hi FolksHope can someone help me understanding and demistying Fabric routing table VRF routing table shows only connected devices and routes for other IP pools in same VRF and other hand Global routing table maintain default and RLOC routes learned L...
