For simplictiy, I'll refer here to L3out External EPGs by their external subnets, and I'm only asking about external subnets.What I'm concerned about is if I start with a contract that permits all traffic from ExtEPG_0.0.0.0/0 to some EPG1, and 2yr l...

Is there a way to add description (that will appear on CLI "show interface description") to mgmt0 using the APIC v6 GUI?I'm seeing posts that talk to API and CLI methods. Our operations team will only use the GUI to configure, and the CLI only to in...

I feel like I'm missing something that should be obvious. I'm at a loss for identifying where to define a host or a subnet as a source or destination within the contract policy heirarchy.If I have a contract, I can specificy allowed/denied TCP and UD...

I have an 8000-series router running IOS XR. I need SNMPv2 to work, but by default that enables SNMPv3. I need to explicitely disable SNMPv3 without disabling SNMPv2.ACLs don't seem to work on the SNMPv2 configuration line. ACL'ing the physical in...

I remember reading some time ago about "Failover Ethernet" on Catalyst switchports. This was kinda like a port-channel in "mode on" except that it was not a port-channel, but still bound two interfaces together so that only one ever was active, with...

Hi @Sergiu.Daniluk ,I want to thank you for this explanation. I've been struggling with finding a sane explanation of static pervasive routes, this is the first I could find.If I may ask a follow-up? We have an L3 FW with a PBR policy, so that it w...

A point of clarification - a VLAN interface will stop forwarding if there are no ports in the VLAN that are forwarding in STP. So you can have up/up interfaces in the VLAN, but if none are "FWD" in STP then the VLAN interface will still be down.

Perfect! Thanks, that's exactly what I was looking for.And yes, CDP/LLDP are awesome tools, I trust them far more than interface descriptions. But we try to set interface descriptions as well, as a matter of practice, for those times where you're n...

And I heartily endorse your excellent naming scheme.and IPs?yeah, well, I had good guidance....Avoiding micro-segmentation is always a good idea......intra-EPG isolation on the EPG......Intra-EPG contracts...I think I should clarify. Example below (...

Thanks @Ali Aghababaei and @RedNectar. I had a proper responses written about why some of those won;t work in my environment, but it became very "woe is me" sounding so I'll save you from that.Summary:I can't really crack up the EPGs (I need to be Ne...
