[Click] Recommendation for network TAPs

Agreed. I am not very much keen on using Click as a tap device since
(i) I do not want to include tapping artifacts in the packet
parameters (timestamp accuracy, delay)  (ii) I want the tap to be
extremely reliable.

1000Mbps and media type primarily copper (rj45)/

Creating SPAN sessions on Cisco switches do not hold well esp if it's
a ISR (Cisco 3845)..On the 6504s' I had issues with the SPAN rate and
mirrored rate providing different values  due to ASIC limitations or
IOS bugs.

I am looking to use taps for full-duplex 1Gbps line rate. I am
exploring aggregate and the non-aggregate varieties.. Any
recommendation of vendors/companies?
