Configuring Static IP Peers for CFS over IP

Multicast forwarding is disabled by default in some devices. For example, IBM Blade chassis has
multicast forwarding disabled, especially on external ethernet ports and there is no method to enable it.
NPV devices use only IP as the transport medium and do not have ISL connectivity or FC domain.
To enable CFS over IP on the switches that do not support multicast forwarding, multicast forwarding
has to be enabled on the ethernet IP switches all along the network that physically connects the switch.
In such cases, you can configure static IP peers for CFS distribution over IP.
CFS uses the list of configured IP addresses to communicate with each peer and learn the peer switch
WWN. After learning the peer switch WWN, CFS marks the switch as CFS-capable and triggers
application-level merging and database distribution.
The following MDS 9000 features require static IP peer configuration for CFS over IP distribution:
•
•
Cisco MDS Fabric Manager discovers NPV devices by reading the name server database on the NPV
core switch, which is also used to manage the static peer list at an NPV switch for CFS distribution over
IP using static peers.
Fabric Manager 4.1(1) and later provides a one-time configuration wizard to manage the peer list of the
discovered NPV peers on a switch. When the peer list is cofigured on a switch, CFS enables distribution
using the IP static peers on all members of the list and propagates the peer list to all members on the list.

N port virtualization devices have IP as the communication channel because NPV switches do not
have FC domain. NPV devices use CFS over IP as the transport medium. For more information, see
