FC Port Channel between UCS and MDS.

santoshsurya · ‎04-02-2015

Hi All,

I am new to Cisco Fabric Concepts. In my enviornment i have a F port channel(8 Port Group) created on MDS 9513 switch and this Fport

channel is connected to Cisco UCS 6296 FI. The Cisco UCS Blade servers are connected to the Fabric Interconnect .

On MDS NPIV is enabled.

Can anyone explain the below questions.

1. Why do we create an F port Channel Group and connect it to the UCS FI? Is this something similar to Brocade Edge to AG Switch Connectivity.

2. How to configure F port Channel Group in MDS . Can anyone explain with an example.

3. Do we need to make any Configuration on UCS FI ports for server connectivity and Channel port Connectivity if yes what are the steps required to

do the same.Does the WWPN shows up in the FLOGI Database if the connectivity and configuration looks good in UCS FI and MDS.

4. What happens when a VSAN on MDS switch is added to the Port Channel.

Thanks and Regards,

Santosh surya

1. Why do we create an F port Channel Group and connect it to the UCS FI? Is this something similar to Brocade Edge to AG Switch Connectivity.

F port channel is proprietary; therefore any such F port channel between UCS FI and Brocade doesn't work.

2. How to configure F port Channel Group in MDS . Can anyone explain with an example.

flogi database is on the MDS, not FI; there are however UCS CLI commands, like "show npv ...."

4. What happens when a VSAN on MDS switch is added to the Port Channel.

If its not created on UCS, it will just not become the status "up"
