Access Control Lists (ACLs) for the Series 3400cl and Series 6400cl Switches
General ACL Operating Notes
ACLs Do Not Filter Traffic Generated by the Switch. Because ACLs on
the 3400cl/6400cl switches filter only inbound traffic at the inbound physical
port, outbound traffic from any source is not filtered by any ACL(s) configured
on the switch. Filtering of such traffic must be done at a downstream device.
< acl-list-# >: Unable to apply access control list.
The indicated ACL cannot be applied to an interface because an ACL is already
assigned to the interface. The command fails for all included interfaces,
including any that do not already have an ACL assigned.
Duplicate access control entry.
The switch detects an attempt to create a duplicate ACE in the same ACL.
