↑ CFS Distribution

Fabric:思科把以太网，IP，存储网络统一，称为Fabric.

CFS distributes configuration changes to multiple devices across a complete network. CFS supports the following types of distribution:

•CFS over Ethernet (CFSoE)—Distributes application data over an Ethernet network.

•CFS over IP (CFSoIP)—Distributes application data over an IPv4 network.

•CFS over Fibre Channel (CFSoFC)—Distributes application data over a Fibre Channel, such as a virtual storage area network (VSAN). If the device is provisioned with Fibre Channel ports, CFSoFC is enabled by default.

Configurations

This document uses these configurations:

Step 1
Destination port configuration switch7000-1#configure terminal switch7000-1(config)#interface ethernet 3/48 !--- Configures the switchport parameters for a port. switch7000-1(config-if)#switchport !--- Configures the switchport interface as a SPAN destination. switch7000-1(config-if)#switchport monitor switch7000-1(config-if)#no shut switch7000-1(config-if)#exit

Step 1

Destination port configuration

switch7000-1#configure terminal
switch7000-1(config)#interface ethernet 3/48


!--- Configures the switchport parameters for a port.

switch7000-1(config-if)#switchport


!--- Configures the switchport interface as a SPAN destination.

switch7000-1(config-if)#switchport monitor
switch7000-1(config-if)#no shut
switch7000-1(config-if)#exit

Step 2
SPAN session configuration switch7000-1(config)#monitor session 1 !---Configure the source port with traffic direction. switch7000-1(config-monitor)#source interface ethernet 3/11 both(想要被抓取的流量) !--- Configure the destination port. switch7000-1(config-monitor)#destination interface ethernet 3/48（连接分析仪的端口） !--- To enable the SPAN session, by default session in shutdown state. switch7000-1(config-monitor)#no shut switch7000-1(config-monitor)#exit !--- To save the configurations in the device. switch7000-1(config)#copy running-config startup-config

Step 2

SPAN session configuration

switch7000-1(config)#monitor session 1


!---Configure the source port with traffic direction.

switch7000-1(config-monitor)#source interface ethernet 3/11 both(想要被抓取的流量)


!--- Configure the destination port.

switch7000-1(config-monitor)#destination interface ethernet 3/48（连接分析仪的端口）


!--- To enable the SPAN session, by default session in shutdown state.

switch7000-1(config-monitor)#no shut
switch7000-1(config-monitor)#exit


!--- To save the configurations in the device.

switch7000-1(config)#copy running-config startup-config

Verify

Use this section to confirm that your configuration works properly.

The Output Interpreter Tool (registered customers only) (OIT) supports certain show commands. Use the OIT to view an analysis of show command output.

The show monitor command gives the status of the SPAN sessions.

switch7000-1#show monitor

Session  State        Reason                  Description
-------  -----------  ----------------------
--------------------------------
1        up           The session is up

The show monitor session all command gives a summary of the current SPAN configuration.

switch7000-1#show monitor session all
    
  session 1
---------------
type              : local
state             : up
source intf       :
    rx            : Eth3/11
    tx            : Eth3/11
    both          : Eth3/11
source VLANs      :
    rx            :
    tx            :
    both          :
filter VLANs      : filter not specified
destination ports : Eth3/48

From these commands you can verify the SPAN configuration on the Nexus 7000 Series Switches.
