Known Behaviors

The following table lists limitations in system architecture that have yet to be resolved.

Table 1. Known Issues, Platform-Specific, and Feature Change Requests (CRs) in 33.6.1
Defect Number	Description
EXOS-39069	ACL rules that use the `vlan-format` match condition (for example, `vlan-format outer-tagged`) cannot be applied to the `any` or `vlan` binding points. Attempting to do so returns: `Error: ACL install operation failed - internal failure`. This condition is supported only when bound to a specific physical port. Workaround: Add a `source-physical-port` qualifier to the ACL entry. The rule can then be successfully installed on `any` or a VLAN binding point.
EXOS-39140	The IP Multicast NAT feature is not supported on stacking.
