Field Notices are notifications that are published for significant issues, other than security vulnerability-related issues, that directly involve Cisco products and typically require an upgrade, workaround, or other customer action.
A Field Notice may be labeled as "Expired" on Cisco.com once the product issue becomes obsolete or all affected products reach their end of support date. Cisco provides the information contained on this page and all Field Notices officially in English only.
