Downloading and installing the Cisco switch NX-OS software

You must download the switch operating system file and RCF file to each switch in the MetroCluster IP configuration.

Before you begin

This task requires file transfer software, such as FTP, TFTP, SFTP, or SCP, to copy the files to the switches.

About this task

These steps must be repeated on each of the IP switches in the MetroCluster IP configuration.

You must use the supported switch software version.

  1. Download the supported NX-OS software file from the CISCO Web site.
  2. Copy the switch software to the switch: copy sftp://root@server-ip-address/tftpboot/NX-OS-file-name bootflash: vrf management

    Example

    In this example, the nxos.7.0.3.I4.6.bin file is copied from SFTP server 10.10.99.99 to the local bootflash:

    IP_switch_A_1# copy sftp://root@10.10.99.99/tftpboot/nxos.7.0.3.I4.6.bin bootflash: vrf management
    root@10.10.99.99's password: password
    sftp> progress
    Progress meter enabled
    sftp> get   /tftpboot/nxos.7.0.3.I4.6.bin  /bootflash/nxos.7.0.3.I4.6.bin
    Fetching /tftpboot/nxos.7.0.3.I4.6.bin to /bootflash/nxos.7.0.3.I4.6.bin
    /tftpboot/nxos.7.0.3.I4.6.bin                 100%  666MB   7.2MB/s   01:32
    sftp> exit
    Copy complete, now saving to disk (please wait)...
  3. Verify on each switch that the switch NX-OS files are present in each switch's bootflash directory: dir bootflash:

    Example

    The following example shows that the files are present on IP_switch_A_1:

    IP_switch_A_1# dir bootflash:
                      .
                      .
                      .

                      .
                      .
                      .

    15018205184 bytes total
    IP_switch_A_1#
  4. Install the switch software: install all nxos bootflash:nxos.version-number.bin
    The switch will reload (reboot) automatically after the switch software has been installed.

    Example

    The following example shows the software installation on IP_switch_A_1:

    IP_switch_A_1# install all nxos bootflash:nxos.7.0.3.I4.6.bin
    Installer will perform compatibility check first. Please wait.

  5. Wait for the switch to reload and then log in to the switch.

    After the switch has rebooted the login prompt is displayed:
