Field Reference
IPv6 Policy Maps Add or Edit Match Condition and Action Dialog Boxes
Use the Add or Edit Match Condition and Action dialog boxes to define an Extension Header match
criterion and action for an IPv6 policy map. The contents of the Extension Headers are not processed;
an action is applied based solely on the presence of a specified EH type.
The fields in these dialog boxes change based on the criterion you select.
Note You can apply multiple match definitions to one IPv6 policy map.

These criteria entries are created and edited in the IPv6 Policy Maps Add or Edit Match Condition and
