Open Caveats – Cisco IOS XE Amsterdam 17.3.8a
There are no open caveats for this release.
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes open and resolved severity 1 and 2 caveats and select severity 3 caveats:
The “Open Caveats” sections list open caveats that apply to the current release and may apply to previous releases. A caveat that is open for a prior release and is still unresolved applies to all future releases until it is resolved.
The “Resolved Caveats” sections list caveats resolved in a specific release, but open in previous releases.
The bug IDs are sorted alphanumerically.
Note |
The Caveats section includes the bug ID and a short description of the bug. For details on the symptoms, conditions, and workaround for a specific caveat you must use the Bug Search Tool. |
