deny (IPv6 access-list configuration)
deny (IPv6 access-list configuration)
Use the deny command in IPv6 access list configuration mode on the switch stack or on a standalone
switch to set deny conditions for an IPv6 access list. Use the no form of this command to remove the
deny conditions.

protocol}] [routing] [sequence value] [time-range name]
Note This command is available only if you have configured a dual IPv4 and IPv6 Switch Database
Management (SDM) template on the switch. This command is not supported on switches running the
LAN base feature set.
Syntax Description protocol Name or number of an Internet protocol. It can be one of the keywords ahp,
esp, icmp, ipv6, pcp, sctp, tcp, or udp, or an integer in the range from 0 to
255 representing an IPv6 protocol number.
source-ipv6-prefix/prefix-
length
The source IPv6 network or class of networks about which to set deny
conditions.
This argument must be in the form documented in RFC 2373 where the
address is specified in hexadecimal using 16-bit values between colons.
