Parameters
<port> {[add | delete] source ports <portlist> [rx | tx | both]}
{group_id <value 1-4>}
<value 1-4>
<value 1-4>
<value 1-4> {target_port <port> | [add | delete] source ports <portlist> [rx | tx |
both] | state [enable | disable]}(1)
Used to configure a mirror port − source port pair on the switch. Traffic from any source port
to a target port can be mirrored for real-time analysis. A logic analyzer or an RMON probe
then can be attached to study the traffic crossing the source port in a completely unobtrusive
manner. When mirroring port traffic, please note that the target port must be configured in the
same VLAN and operates at the same speed as the source port. If the target port is
operating at a lower speed, the source port will be forced to drop its operating speed to
match that of the target port.
config mirror port <port> {[add | delete] source ports <portlist> [rx | tx | both]}
The config mirror command allows a range of ports to have all of their traffic also sent to a
destination port − where a network sniffer or other device can monitor the network traffic. In
addition, you can specify that only traffic received by or sent by or both are mirrored to the
target port.
This command used for single mirror session configuration primarily. If used for multiple
session configurations, it configures the parameters on mirror group 1. If group 1 not exist,
create group 1 firstly, and than configure the parameters on group 1.
port - The port that will receive the packets duplicated at the mirror port.
add - The mirror entry to be added.
delete - The mirror entry to be deleted.
portlist - The port that will be mirrored. All packets entering and leaving the source port can
be duplicated in the mirror port.
rx - Allows the mirroring packets received (flowing into) the port or ports in the port list.
tx - Allows the mirroring packets sent (flowing out of) the port or ports in the port list.
both - Mirrors all the packets received or sent by the port or ports in the port list.
Only Administrator and Operator-level users can issue this command.
