Monitor Port on 3Com 4400

Hallo zusammen,

Heute musste ich bei einem Kunden auf einem 3Com 4400 24 Port Switch ein Monitor Port einrichten um den Netzwerkverkehr mitzuschneiden. Musste da ein bisschen suchen, bis ich gefunden habe wie das geht. Wer erwartet das schon under "feature"?

Und so gehts: In diesem Beispiel wird der Traffic von Port 17 an den Port 3 kopiert.

Mit Telnet auf den Switch verbinden und einloggen.

Menu options: --------------3Com SuperStack 3 Switch 4400---------------
 bridge             - Administer bridge-wide parameters
 feature            - Administer system features
 gettingStarted     - Basic device configuration
 logout             - Logout of the Command Line Interface
 physicalInterface  - Administer physical interfaces
 protocol           - Administer protocols
 security           - Administer security
 system             - Administer system-level functions
 trafficManagement  - Administer traffic management

Type  ? for help
---------------------------3COM Superstack 4400, Unit 1 (1)-------------
Select menu option: feature

Menu options: --------------3Com SuperStack 3 Switch 4400---------------
 cacheConfig        - Administer Webcache support
