deny (for IPv6 ACLs)
Configure a filter that drops IPv6 packets that match the filter criteria.
Syntax
deny {
ipv6-protocol-number
| icmp | ipv6 | tcp | udp} [count
[byte]] [dscp
value
] [order] [fragments] [log [interval
minutes
] [threshold-in-msgs [
count
]] [monitor]
To remove this filter, you have two choices:
• Use the
no seq sequence-number
command syntax if you know the filter’s
sequence number
• Use the
no deny {ipv6-protocol-number | icmp | ipv6 | tcp |
udp}
command

as
255
.
