Resolved! L3 Handoff and LAN Automation
Hi!In my test environment, I'm deploying a C9500 as Border Node, connected to a Fusion Router (C9300) and a C9300 as the edge device.I did LAN Automation with the Fusion Router as the seed.The process went as expected, the C9500 and the C9300 were di...
Resolved! LAN Automation vs PnP conflict
Hello, I want to onboard a Cat9K switch into my SDA fabric using LAN Automation. But since we have configured an IP Pool under INFRA_VN to permit the onboarding of extended nodes (3560CX, ...), it looks like the Cat9K goes through the PnP process dur...
I have a legacy network that is migrating to ACI with connections to external elements that cannot be reconfigured. In the network below, our core switch provides the L3 gateway for the 10.10.10.x subnet however there is a 172.16.1.X subnet behind th...
In SD-Access solution. In case of ISE totally down is it possible to create multiple critical vlans for each VN for example one critical vlan for users, another one for IOT devices and third one for voice.or it must be single critical data vlan for t...
HiI have a customer that experiences the following error on 9300 series SDA-fabric switches.%IDMGR-3-INVALID_ID: bad id in id_get (Out of IDs!) (id: 0x0)-Traceback= 1#4dda8d7f3bd9dd47b0e9fdcda9698d76 :648187465000+3F1B898 :648187465000+18D579A8 :6481...
We are running wired & wireless SDA at one of our facilities. Seems to work fairly well. In the last couple of months, we've been encountering some weird wireless connectivity issues. At completely random times, wireless appears to drop in random are...
ISE starting from something like 2.2 is known supporting multiple TrustSec policies matrices, when with the same SGT-set admin may vary with policies per NAD. In SDA, you usually have DNAC as orchestrator of TrustSec matrix with ISE reproducing only...
Good dayI need guidance on how to configure multiple Multicast instances on Cisco Catalyst Center for different services, is there a guide on this?
Hi, I am trying to deploy a Guest SSID on an SD-Access Fabric-in-a-box (9300LM with embedded WLC) operating in mixed mode. The Guest SSID will in non-Fabric mode anchored to another 9800-L-F-K9 anchor WLC in the DMZ. I have created and added the ...
Hi team!This is currently only a design question — there is no active deployment at the moment.The topology consists of a Border Node (Catalyst 9500) connected to a Nexus pair acting as Fusion routers. The Nexus pair is operating with vPC.From my und...
I am removing a single switch from a LAN Automated stack of 3x switches but one of the fibre links is in the switch im trying to recover.I have been through the "delete link" process quite a few times so I am familar with it (aswell as the "add link"...
Hi Experts,I have started working on SD Access recently. Just curious about the failover mechanism here.I am sharing the design scenario which is standard for most of the designs. We have SD WAN for WAN connectivity and SD WAN is managed by another v...
Hi,Is it true that in SD-Access, the VNs capacity of the fabric is determined by the least switch VNs capacity?So if I have 9300 switches and 9200 switches, the VNs capacity per switch in the fabric will be 4 VNs only per switch?I couldn't find it me...
Hi all,i have a small SD-Access Deployment with 4 fabric sites, one of them is a very small site deployed with FiaB, all the Transit are configured as "IP-based".In every fabric site (except the "FiaB" one) i have two Border Nodes where i configured ...
