I'm attempting to automate the creation of our Service Profile Templates, and have just about everything done. However, I am unable to figure out how to configure a Service Profile Template to use a SAN Connectivity Policy. I do not see that as an ...

Hi all, We have the a proposed design of 9x routers in a ring topology. These routers would be in 9x different data centers spanning a geographical area the size of a large USA state. The design is the same as the design at this link, but instead ...

We have a Nexus 7700 running two different contexts. One is the Admin context and then another standard context. They are configured with IP addresses within the same subnet (10.101.0.0/24), but they can't communicate with each - other ping doesn't...

Hi Reza,Since these are VDC, those IPs are all on the physical mgmt0 on the switch. mgmt0 is physically shared across all VDC, so yes they are technically on the same VLAN. ThanksSean

Hi Reza, thanks for the reply. I understand they are two different switches, but they both have IPs in the same subnet and thus should be able to talk to each other, through the external switch that mgmt0 is connected. Here are the IPs assigned:10....
