Host address—You can use the host keyword and an IPv6 address to specify a host as a source or
destination. The syntax is as follows:
host IPv6-address
This syntax is equivalent to IPv6-address/128.
The following example shows how to specify the source argument with the host keyword and the
2001:0db8:85a3:08d3:1319:8a2e:0370:7344 IPv6 address:
switch(config-acl)# permit icmp host 2001:0db8:85a3:08d3:1319:8a2e:0370:7344 any
•
Any address—You can use the any keyword to specify that a source or destination is any IPv6
address. For examples of the use of the any keyword, see the examples in this section. Each example
shows how to specify a source or destination by using the any keyword.
