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

sent.
● 00:00:00:00:00:00 — (Optional) Enter which bits in the MAC address must match. If you do not
enter a mask, a mask of 00:00:00:00:00:00 applies.
