Installing the Reference Configuration File (RCF)

You can install the RCF after setting up the Nexus 92300YC switch for the first time.

Steps

  1. Connect the cluster switch to the management network.
  2. Use the ping command to verify connectivity to the server hosting the RCF.
    Example
    This example verifies that the switch can reach the server at IP address 172.19.2.1:
    cs2# ping 172.19.2.1
    Pinging 172.19.2.1 with 0 bytes of data:
    
    Reply From 172.19.2.1: icmp_seq = 0. time= 5910 usec.
  3. Copy the RCF to the Nexus 92300YC switch:
    Example
    cs2# copy sftp: bootflash: vrf management
    Enter source filename: /code/Nexus_92300YC_RCF_v1.0.2.txt
    Enter hostname for the sftp server: 172.19.2.1
    Enter username: user1
    
    Outbound-ReKey for 172.19.2.1:22
    Inbound-ReKey for 172.19.2.1:22
    user1@172.19.2.1's password: 
    sftp> progress 
    Progress meter enabled
    sftp> get   /code/Nexus_92300YC_RCF_v1.0.2.txt  /bootflash/nxos.9.2.2.bin 
    /code/Nexus_92300YC_R  100% 9687   530.2KB/s   00:00    
    sftp> exit 
    Copy complete, now saving to disk (please wait)...
    Copy complete.
    
  4. Merge the RCF with the running-config of the switch:
    Example
    cs2# copy bootflash:Nexus_92300YC_RCF_v1.0.2.txt running-config
    
    Disabling ssh: as its enabled right now:
     generating ecdsa key(521 bits)......
    generated ecdsa key
    
    Enabling ssh: as it has been disabled 
     this command enables edge port type (portfast) by default on all interfaces. You
     should now disable edge port type (portfast) explicitly on switched ports leading to hubs,
     switches and bridges as they may create temporary bridging loops.
    
    Edge port type (portfast) should only be enabled on ports connected to a single
     host. Connecting hubs, concentrators, switches, bridges, etc...  to this
     interface when edge port type (portfast) is enabled, can cause temporary bridging loops.
     Use with CAUTION
    
    Edge Port Type (Portfast) has been configured on Ethernet1/1 but will only
     have effect when the interface is in a non-trunking mode.
    
    ...

    Copy complete.
    
  5. Verify on the switch that the RCF has been merged successfully: show running-config
    Example
    cs2# show running-config
    !Command: show running-config

  6. Save the running configuration so that it becomes the startup configuration when you reboot the switch:
    Example
    cs2# copy running-config startup-config
     
    [########################################] 100%
    Copy complete, now saving to disk (please wait)...
    Copy complete.
    
  7. Reboot the switch and verify that the running configuration is correct: reload
    Example
    cs2# reload
    
    This command will reboot the system. (y/n)?  [n] y
