Hi there, I am coming from an N5K - N7K setup, where I know that N5k regularly do cut through switching and N7K always store and forward.That is relevant to know in regards to how broken frames (CRC errors) are discarded or spread through the fabric....
G'day everyone, I have an ASR 1K where I have a hierarchical Qos policy doing sub linerate shaping on the main interface based on DSCP. That is working with no problem.Now what happens if I add a sub-interface without any policy-map? Is the main shap...
Hallo, we have PTP enabled within the ACI fabric, and one of the spines has taken over the grandmaster role.Now we have an external ptp grandmaster reachable via ethernet and I'd like the ACI fabric to use this clock instead of the spine. However I d...
G'day everyone,
I am trying to allow a vmware virtual machine to send frames with a "forged" MAC address. By forged I mean a MAC address that is not supplied by Vcenter, like you would need for a bond interface.
I have seen this option for trunk po...
Hallo,
I am a blockhead right now in terms of how to integrate a virtual router into aci. I know how to attach physical firewalls with a L3out, however I don't know how to do this with virtual machines.
We have an ESX-environment with AVS (soon A...
We use regular vmware DVS with VMX3 interfaces for our Citrix based VDI infrastructure, but haven't given much thought to this honestly.When we see latency related problems then they are usually caused by our tiny MPLS WAN bandwidth between the offic...
The switch plugin was called AVS and was a very powerful and great solution. Unfortunately VMware killed any 3rd party switches, thus AVE was created, which is nothing but a regular VM running on each ESX server. All VMs on this host can only talk to...
Have a look at Vmware and SR-IOV, a more standardized way to bypass the hypervisor / DVS for Network IO. I am however no expert for UCS, so you may need to do some research in regards to UCS and Cisco VIC support for that. ACI is not going to help yo...
Just a guess:Did you check the path metric for the vPC Tep address from the spine before reloading the second switch?You should see 2 equal cost routes, otherwise there is still the "set-overload-bit on start-up"-timer active, preventing the spine fr...
