Spanning-tree - Rapid PVST+ switches interaction with ACI ACI fabric does not run spanning-tree. By default, an EPG in ACI will just flood BPDUs (even if Hardware proxy mode is chosen for the BD). The downstream Spanning-tree switches are supposed t...

Hi Maurice,
I did the setup 2 years ago, but there was no VPC anywhere from what I remember. Hence essentially 4 spanning-tree port in the same MST instance (2 each nexus7k).
I just retest similar setup quickly in my lab and I never see slow conve...
wrr queue-limit is always enforced. It is really making a hardware separation on the port asic of the line card. Aka on a 6748 you have around 1.2 M of Tx Buffer and it is splitted according to those weightyou can see the exact splitting using : remo...
Likely those switch do not allow routing and are pure L2 switches that do not allow more than one L3 interface at a time.but as said earlier better check with Dell documentation.ROland
you have configured a very low queue-limit for Q1 (5) so that makeswhere as Q2 as 25, Q3, 40 and Priority queue 15 --> that makes only 5 /(5+25+40+15) = 5/85 --> 6% of the buffersit is very low, so a very limited burst will be enough to get drop. in ...
