1. - re: Bruno's solution. I did this for a long time. Only real drawback from a practical point of view is if you have redundant paths you need 2 hubs or else you've built a new SPF.. 2. Saw Cisco config, so thought I'd post what Nortel 350/450 looks like: (view in courier). This is under switch configuration-->Port Mirroring configuration Port Mirroring Configuration Monitoring Mode: [ <-> Port X and Port Y <-> ] Monitor Unit/Port: [ 1/9 ] Unit/Port X: [ 1/8 ] Unit/Port Y: [ 2/8 ] Address A: [ 00-00-00-00-00-00 ] Address B: [ 00-00-00-00-00-00 ] Currently Active Port Mirroring Configuration --------------------------------------------- Monitoring Mode: <-> Port X and Port Y <-> Monitor Unit: 1 Port: 9 Unit X: 1 Port X: 8 Unit Y: 2 Port Y: 8 This is the port mirroring config screen. In this particular example there are 2 switches in cascade (linked). The monitor port is unit 1, port 9. It is monitoring all traffic in and out (<->) of unit 1 port 8 and unit 2 port 8. The older versions of the Nortel code don't (AFAIK) support mirroring multiple ports, but software & firmware upgrades are *free* from Nortel for the 350/450. Last pertinant detail - the monitoring port is unreachable so you need another NIC to be a normal "comm" NIC so you can talk to the sensor, have it log etc. hth Joe _______________________________________________________________ Have big pipes?
