config mirror port add
Purpose | Used to configure a mirror port − source port pair on the Switch. |
Syntax | config mirror port <port> add source ports <portlist> [rx tx |
| both] |
Description | 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, you can specify |
| that only traffic received by or sent by one or both is mirrored to |
| the Target port. |
Parameters | port <port> − This specifies the Target port (the port where |
| mirrored packets will be sent). The port is specified by listing the |
| lowest slot number and the beginning port number on that slot, |
| separated by a colon. For example, 1:3 specifies slot number 1, |
| port 3. 2:4 specifies slot number 2, port 4. |
| add source ports – The port or ports being mirrored. This cannot |
| include the Target port. |
| <portlist> − Specifies a range of ports to be mirrored. The |
| port list is specified by listing the lowest slot number and the |
| beginning port number on that slot, separated by a colon. |
| Then the highest slot number, and the highest port number |
| of the range (also separated by a colon) are specified. The |
| beginning and end of the port list range are separated by a |
| dash. For example, 1:3 specifies slot number 1, port 3. 2:4 |
| specifies slot number 2, port 4. |
| ports between slot 1, port 3 and slot 2, port 4 − in numerical |
| order. |
| 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 |
