Layer 2 Switching Commands 571
This command specified in Interface Configuration mode only affects a
single interface, whereas the Global Configuration mode setting is applied to
all interfaces. The optional control-plane keyword allows application of an
ACL on the CPU port ingress queue. Control plane packets (e.g., BPDUs) are
dropped because of the implicit deny all rule added at the end of every access
control list. To mitigate this behavior, permit rules must be added by the
operator to allow the appropriate control plane packets to ingress the CPU
(i.e., ARP, DHCP, LACP, STP BPDU, etc.). The control-plane keyword does
not filter traffic received over the out-of-band port.
Example
The following example attaches an IPv6 access control list to an interface.
console(config-if-Gi1/0/1)#ipv6 traffic-filter DELL_IP6 in
