Layer 2 Switching Commands 517
User Guidelines
Dell EMC Networking switches support configuration of multiple access
groups on interfaces. An optional sequence number may be specified to
indicate the order of this access list relative to other IPv6 access lists already
assigned to this interface and direction. A lower number indicates higher
precedence order. If a sequence number is already in use for this interface and
direction, the specified IPv6 access list replaces the currently attached IPv6
access list using that sequence number. If the sequence number is not
specified for this command, a sequence number that is one greater than the
highest sequence number currently in use for this interface and direction is
used.
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

show ipv6 access-lists
Use the show ipv6 access-lists command in User Exec and Privileged Exec
mode to display an IPv6 access list and all of the rules that are defined for the
IPv6 ACL. Use the [name] parameter to identify a specific IPv6 ACL to
display.
