    Hello,

    if you have non cisco catalyst devices, you have
    big problems in creating (multi port) SPAN-like
    monitoring.

    You can use taps (esp. from shomiti or NetOptics).
    But these taps support only the monitoring of one port.
    Yes, shomiti has the Century with 12 tap ports
    but only one analyse port. NetOptics has an 6-Port tap
    with also 6 analyse ports but only for SX/LX.

    Further you can use an additional Catalyst for
    creating "in-line" taps. But, if this catalyst
    failed, the servers are all down. No network
    administrator will use such additional Catalyst.

    You know another technical way for solving this
    problem or exist another product like from Shomiti or
    NetOptics with support for multi port taps for
    100BaseTX AND multiple analyse ports ?

    Birk
