Chapter 7 Using Cisco Fabric Services
CFS Distribution
Step 7 Click the Apply Changes icon to commit the configuration changes for that feature and distribute the
changes through CFS.
To globally disable or enable CFS distribution on a switch using Device Manager, perform this task:
Step 1 Choose Admin > CFS (Cisco Fabric Services).
You see the CFS dialog box with the CFS status for all features on that switch.
Step 2 Uncheck or check the Globally Enabled check box to disable or enable CFS distribution on this switch.
Step 3 Click Apply to disable CFS on this switch.
CFS Distribution over IP
CFS distribution over IP supports the following features:
• Physical distribution over an entirely IP network.
• Physical distribution over a hybrid Fibre Channel and IP network with the distribution reaching all
switches that are reachable over either Fibre Channel or IP.
Note The switch attempts to distribute information over Fibre Channel first and then over the IP
network if the first attempt over Fibre Channel fails. CFS does not send duplicate messages if
distribution over both IP and Fibre Channel is enabled.
• Distribution over IP version 4 (IPv4) or IP version 6 (IPv6).
Note CFS cannot distribute over both IPv4 and IPv6 from the same switch.
• Keepalive mechanism to detect network topology changes using a configurable multicast address.
• Compatibility with Cisco MDS 9000 Family switches running release 2.x or later.
Figure 7-1 shows a network with both Fibre Channel and IP connections. Node A forwards an event to
node B over Fibre Channel. Node B forwards the event node C and node D using unicast IP. Node C
forwards the event to node E using Fibre Channel.
