● A::B/x — (Optional) Enter the source network mask in /prefix format (/x) and the destination
mask.
● any — (Optional) Set all routes which are subject to the filter:
○ capture — (Optional) Capture packets the filter processes.
○ count — (Optional) Count packets the filter processes.
○ byte — (Optional) Count bytes the filter processes.
○ dscp value — (Optional) Deny a packet based on the DSCP values, from 0 to 63.
○ fragment — (Optional) Use ACLs to control packet fragments.
● host ipv6–address — (Optional) Enter the IPv6 address to use a host address only.
Default Not configured
Command Mode IPV6-ACL
Usage
Information
OS10 cannot count both packets and bytes; when you use the count byte options, only bytes
increment. The no version of this command removes the filter.
Example
OS10(config)# ipv6 access-list ipv6test
OS10(conf-ipv6-acl)# deny ipv6 any any capture session 1
Supported
