Usage
Information
OS10 cannot count both packets and bytes; when you enter the count byte options, only bytes
increment. The no version of this command removes the filter.
Example
OS10(conf-ipv4-acl)# permit ip any any capture session 1
Supported
Releases
10.2.0E or later
permit ipv6

host ipv6-address] [capture | count | dscp value | fragment | log]
Parameters
● A::B — (Optional) Enter the source IPv6 address from which the packet was sent and the
destination address.
● A::B/x — (Optional) Enter the source network mask in /prefix format (/x) and the destination
mask.
● any — (Optional) Enter the keyword any to specify any source or destination IP address.

● capture — (Optional) Enter to capture packets the filter processes.
● count — (Optional) Enter to count packets the filter processes.
● byte — (Optional) Enter to count bytes the filter processes.
● dscp value — (Optional) Enter to deny a packet based on the DSCP values, from 0 to 63.
