services that are available on a host or server, each with a list of hosts or servers
permitted or denied to use the service. ACLs can generally be configured to control
inbound traffic and, in this context, they are similar to firewalls.
ACE is an acronym for Access Control Entry. It describes access permission
associated with a particular ACE ID.
There are three ACE frame types (Ethernet Type, ARP, and IPv4) and two ACE actions
(permit and deny). The ACE also contains many detailed, different parameter options
that are available for individual applications.
ACL status
The Voice VLAN OUI Table page shows the ACL status by different ACL users. Each
row describes the ACE that is defined. A conflict occurs if a specific ACE is not applied
to the hardware due to hardware limitations. The maximum number of ACEs is 512 on
each switch.
The page includes the following fields:
