Command Mode:
IPv6 nomenclature extended access control list mode
Default:
No access control list configured
Example:
Create an extended access control list named udpFlow, denying the igmp
packets while allowing udp packets with destination address 2001:1:2:3::1 and
destination port 32.
Switch(Config)#ipv6 access-list extended udpFlow
Switch(Config-Ext-Nacl-udpFlow)#ipv6 access-list 110 deny igmp any any-destination
Switch(Config-Ext-Nacl-udpFlow)#ipv6 access-list 110 permit udp any host-destination
2001:1:2:3::1 dPort 32
19.2.2.24 permit | deny(ipv6 standard)
Command:[no]{deny|permit}{{<sIPv6Prefix/sPrefixlen>} | any | {host <sIPv6Addr>}}
Function:
Create a standard nomenclature IPv6 access control rule; the “no” form of this
command deletes the nomenclature standard IPv6 access control rule.
Parameter:<sIPv6Prefix>
is the prefix of the source IPv6 address,
<sPrefixlen>
is the
length of the IPv6 address prefix, the valid range is 1
～
128.
<sIPv6Addr>
is the source
IPv6 address.
Command Mode:
Standard IPv6 nomenclature access list mode
Default:
No access list configured by default.
Usage Guide:
Example:
Permit packets with source address of 2001:1:2:3::1/64 while denying those
with source address of 2001:1:2:3::1/48.
Switch(Config)# ipv6 access-list standard ipv6Flow
Switch(Config-Std-Nacl-ipv6Flow)# permit 2001:1:2:3::1/64
Switch(Config-Std-Nacl-ipv6Flow)# deny 2001:1:2:3::1/48
19.2.2.25 time-range
Command:[no] time-range <time_range_name>
Functions:
Create the name of time-range as time range name, enter the time-range
mode at the same time.
Parameters:time_range_name
,time range name must start with letter, and the length
