The C-Series cannot count both packets and bytes, so when you enter the count byte options, only bytes are incremented. permit tcp c e s Configure a filter to pass TCP packets that match the filter criteria. Syntax permit tcp {source address mask | any | host ipv6-address} [operator port [port]] {destination address | any | host ipv6-address} [bit] [operator port [port]] [count [byte]] | [log] [monitor] Parameters To remove this filter, you have two choices: • Use the no seq sequence-number command syntax if you know the filter's sequence number or • Use the no permit tcp {source address mask | any | host ipv6-address} {destination address | any | host ipv6-address} command. source address mask any host ipv6-address operator port port destination address Enter the IPv6 address of the network or host from which the packets were sent in the x:x:x:x::x format followed by the prefix length in the /x format. Range: /0 to /128 The :: notation specifies successive hexadecimal fields of zero. Enter a network mask in /prefix format (/x). Enter the keyword any to specify that all routes are subject to the filter. Enter the keyword host followed by the IPv6 address of the host in the x:x:x:x::x format. The :: notation specifies successive hexadecimal fields of zero (OPTIONAL) Enter one of the following logical operand: • eq = equal to • neq = not equal to • gt = greater than • lt = less than • range = inclusive range of ports (you must specify two port for the port parameter.) Enter the application layer port number. Enter two port numbers if using the range logical operand. Range: 0 to 65535. The following list includes some common TCP port numbers: 23 = Telnet 20 and 21 = FTP 25 = SMTP 169 = SNMP Enter the IPv6 address of the network or host to which the packets are sent in the x:x:x:x::x format followed by the prefix length in the /x format. Range: /0 to /128 The :: notation specifies successive hexadecimal fields of zero. IPv6 Access Control Lists (IPv6 ACLs) | 573
