Service Manual

This mechanism copies all incoming or outgoing packets on one port and forwards (mirrors) them to another port.
The source port is the monitored port (MD) and the destination port is the monitoring port (MG).
Related Commands
permit – assigns a permit filter for IP packets.
permit tcp – assigns a permit filter for TCP packets.
permit tcp
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 [interval minutes] [threshold-in-msgs [count]
[monitor]
To remove this filter, you have two choices:
Use the no seq sequence-number command if you know the filter’s sequence number.
Use the no permit tcp {source address mask | any | host ipv6-address}
{destination address | any | host ipv6-address} command.
Parameters
source 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. The range is /0 to /128.
The :: notation specifies successive hexadecimal fields of zero.
mask Enter a network mask in /prefix format (/x).
any Enter the keyword any to specify that all routes are subject to the filter.
host ipv6-address 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.
operator (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.)
port port Enter the application layer port number. Enter two port numbers if using the range logical
operand. The range is 0 to 65535.
The following list includes some common TCP port numbers:
23 = Telnet
20 and 21 = FTP
25 = SMTP
169 = SNMP
destination address 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. The range is /0 to /128.
The :: notation specifies successive hexadecimal fields of zero.
