Frequently asked questions

What are the latest Cisco Catalyst security advisories?

This page lists recent Cisco security advisories affecting Cisco Catalyst, from the Cisco PSIRT openVuln feed, with severity, CVSS, and CVEs. Confirm the affected software versions against what you run.

How do I fix a Cisco Catalyst vulnerability?

Most Cisco vulnerabilities are fixed by upgrading to a patched software release or applying the documented mitigation. If the platform is end-of-life, the remedy is a refresh. Uniqcli, an authorized Cisco partner, scopes the patch or replacement and can quote it TAA-compliant and GPC-payable.

Is Cisco Catalyst still supported?

Security fixes are only available while a product is supported. Check our Cisco end-of-life lookup to confirm the Last Date of Support, then patch (if supported) or plan a refresh with Uniqcli.
