Cisco SNS 3755

I am trying to use the fiber connections on the SNS 3700 but I am unable to ping the appliance. The ip address is configured on the appliance on port 0 but the appliance is shown to be connected to the switch on port 2. Is this correct or is there something else that needs to be done to use the fiber ports?

The SNS series appliances (used primarily for ISE) must use the port 0 interface (at a minimum) for management and administrative access. You can enable and use the additional ports, but they cannot function as the only in-use interfaces.

Hi Mavin, Thanks for the reply. Firstly I must admit I do not have a lot of experience with the appliance because I have mostly set up virtual machines. I do have port 0 configured with the management IP address configured on it and the appliance shows all five ports are in the up state. When a look at the switch port that the appliance fiber port is connected to. I see the mac address of port 2 on the switch of the appliance but I am still unable the ping the management IP address from the switch or ping the default gateway from the appliance. The only way a can access the appliance is by way of CIMC.  Is it anything special I need to do to be able to use the fiber interfaces on the appliance?

I resolved the issue by shutting down the interface 0 and moving the management IP address to interface 2 or move it to the interface that the fiber is connected to.
