Hi all - I'm looking for some VXLAN advice to fix a strange layer 2 unknown ARP issue I have between some (not all) hosts on the same L2VNI/VLAN which are spread across N9K VTEP's. Example topology is HOST-A is connected in v10 (L2VNI 10010) on 9k-VT...

Hi all,I am playing around with the Velocity templates in DNA (running System ver 1.3.0.159) and it doesn't appear to copy the template changes to the startup-config on switches after deployment (switches running Gilbraltar 16.12.03 and Fuji 16.9.5)?...

Hi community, does anyone know of a maglev/CLI command to change the NTP time servers and/or timezone on the DNA servers themselves? Our cluster's time's out according to the "date" command which is causing time drift errors in assurance.I know runni...

Hi all, we're in the process of getting our SDA fabric deployment up and running using a fabric-in-a-box 9300 with multiple VN's and ISE policy management but hit an issue where I can't seem to find any online guidance.Basically we have 2 VN's pushed...

Hi all, anyone shed any light on a weird issue we've been seeing with our DNAC cluster (running 1.3.3) and ISE (2.6) whereby we can join DNAC and ISE together okay but we can't get DNAC to manage policy and set ISE to read-only, the save button is bl...

Thanks for the screenshots of the suggested multicast configuration - I have configured “ip pim-sparse mode” on the physical point to point links between spine and leafs but not on the underlay loopbacks.That’s the most likely cause of the problem ho...

Same subnet and using multicast pim bidir for the BUM replication....which is why I didn’t think an IP address on the anycast GW SVI was required. ARP requests to the silent host work outside of VXLAN (so not a host problem) - waking the silent host...

Thanks for taking the time to respond.I wrongly thought that any VTEPs receiving BUM traffic within a L2VNI would simply forward to all member ports within the same L2VNI without needing to have an IP address on the SVI for longest prefix matching an...

Thanks for the response - so if I am understanding you correctly you’re saying that every L2VNI must have an SVI with the IP/subnet created on all VTEPs so the VTEPs know which subnets sit behind them (for silent hosts)? So passing the L2VNIs (with S...

All the Nexus 9k’s are VPC pairs with teamed NICs (so HOST-A connected to 9K-VTEP-A which is a VPC pair & HOST-B to 9K-VTEP-B which is another VPC pair)Thanks
