<Sysname> reset acl ipv6 counter 2001

# Clear the statistics about the IPv6 ACL named flow.

<Sysname> reset acl ipv6 counter name flow

rule (in basic IPv6 ACL view)

Parameter rule-id: IPv6 ACL rule number in the range 0 to 65534.

deny: Defines a deny statement to drop matched packets.

permit: Defines a permit statement to allow matched packets to pass.

fragment: Indicates that the rule applies only to non-first fragments. The rule applies to both fragments and non-fragments without this keyword.

source { ipv6-address prefix-length ipv6-address/prefix-length any }: Specifies a source address. The ipv6-address and prefix-length arguments specify a source IPv6 address, and its address prefix length in the range 1 to 128. The any keyword indicates any IPv6 source address.

time-rangetime-name:Specifies the time range in which the rule takes effect. The time-nameargument specifies a time range name with 1 to 32 characters. It is case insensitive and must start with an English letter. To avoid confusion, this name cannot be all.
