    You want to use the set span command.

    I was recently told that for a 6513 that we are buying, we could span 1 port
    to 4 other ports without it degrading performance.

    We haven't purchased this, so i can't tell you if that statement has ever
    held true.

    But spanning one port to one port, i can't see there being a problem.

    You can also span a whole VLAN to one port, you just need to make sure the
    bandwidth of the port is capable of handling the bandwidth of the VLAN.
