DAS-3600 Series Ethernet over VDSL Switch CLI Reference Manual
Parameters
<port> {[add | delete] source ports <portlist> [rx | tx | both]}
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
can then be attached to study the traffic crossing the source port in a completely obtrusive
manner.
config mirror port <port> {[add | delete] source ports <portlist> [rx | tx | both]}
This command allows a range of ports to have all of their traffic also sent to a designated
port, where a network sniffer or other device can monitor the network traffic. In addition, users
can specify that only traffic received by or sent by one or both is mirrored to the Target port.
<port> − This specifies the Target port (the port where mirrored packets will be received). The
target port must be configured in the same VLAN and must be operating 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.
[add | delete] – Specifies if the user wishes to add or delete ports to be mirrored that are
specified in the source ports parameter.
source ports – The port or ports being mirrored. This cannot include the Target port.
<portlist> − This specifies a port or range of ports that will be mirrored. That is, the range of
ports in which all traffic will be copied and sent to the Target port.
rx − Allows the mirroring of only packets received by (flowing into) the port or ports in the port
list.
tx − Allows the mirroring of only packets sent to (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.
The Target port cannot be listed as a source port.
Only Administrator and Operator-level users can issue this command.
