Hello
I am wondering if there is a mechanism that I can use to secure a network against the L2 loop crated on the vserver side, in the Vmware environment with Nexus 1000V.
I know, that Nexus 1000V can prevent against the loop on the external links but, there is no information that there are any features that can prevent against the loop caused by the bridge configured on the OS side on the VMware's virtual server.
Thank you in advance for an answer.
Regards
Lukas

Hello Lukas,
To prevent loops, N1KV does not switch traffic between physical NICs and also, it silently drops the traffic between vNICs that are the bridged by OS.

We do not need explicit configuration on N1KV.
