Nxos703i79bin Upd Download Review

| Source | Status | Recommendation | |--------|--------|----------------| | Cisco.com (Software Download Center) | ✅ Official | Only recommended source | | Third-party file repositories (e.g., random FTP, file-sharing sites) | ❌ Untrusted | Never use – high risk of tampering/malware | | Internal company software repository | ✅ Acceptable | Only if mirrored from Cisco with hash verification |

Critical: Do not download nxos703i79.bin from unofficial sites. Cisco does not host its NX-OS images on public mirrors.

Before loading the .bin onto a Nexus switch, verify:

Step 1: Copy the file to the switch

switch# copy scp://user@tftp-server/nxos703i79bin.upd bootflash:

Step 2: Verify file integrity on the switch

switch# show file bootflash:nxos703i79bin.upd md5sum

Compare this to Cisco’s published hash.

Step 3: Install the update (SMU installation)

switch# install patch bootflash:nxos703i79bin.upd

NV: The system will verify compatibility with the running show version. If it’s the wrong base version, it will reject the patch.

Step 4: Activate the patch

Step 5: Verify installation

switch# show patch
switch# show version | grep patch

You should see the patch ID i79 listed as active.

Step 6: Commit the patch (persist across reloads)

switch# install patch commit bootflash:nxos703i79bin.upd

If you skip this, a reboot will remove the patch.

If the pre-checks pass, confirm the installation. The switch will verify the image signature, unpack the files, reboot the supervisors sequentially (if ISSU), and reload the line cards.

This guide provides a general outline. For precise instructions, consulting the official documentation or a network expert familiar with Cisco Nexus devices is recommended.
