    ????????????

    Maybe I didn't get it, but under that link you can read that:

    The following platforms are supported:

    a.. Cisco 1721 router
    b.. Cisco 1751 router
    c.. Cisco 1760 router
    If you are intrested in cheap solution you can look at cisco 1711 and 1712,
    maybe this will suit you.

    Best Regards

  4. Yes.

    The Cisco WIC-4ESW is supported on Cisco 1721, Cisco 1751, Cisco 1751-V, and
    Cisco 1760 routers.

    oops, your right. Sorry about that.

    However, performance will be dismal at best on the 1721. Smartbits testing
    has show me that 1721 won't pass any more than 2 T1's worth of bandwidth so
    expecting any type of performance on this switch card in the router is
    wishful thinking.

  6. JC,

    The Layer 2 switch performance of the WIC-4ESW isn't limited to 2 x T1
    performance, it can handle full FastEthernet wire rates between WIC-4ESW
    ports. But the Layer 3 performance is limited to 10Mbps because the 1721
    CPU is attached at 10Mbps - so in theory 2 100Mbps on different VLAN ports
    on thw WIC-4ESW could communiate at roughly 10Mb using the 1721 to route
    between VLANs.

    Yes. I have one. The 1721 will only utilize 1 4ESW.

    I guess if you want to use a 1721 with a $300 WIC as an ethernet switch
    that's OK but I can do the same thing by connecting a $20 ethernet switch to
    the ethernet port of the router. So the assumption would be to use the 1721
    at layer 3 to get the most bang for your buck. Also the documentation
    states clearly that Routed Inter-vlan traffic is limited to 10 Full duplex
    however there is no mention of line rate being achieved with that option. I
    still stand by my lab figures that show me the router will never achieve
    anything above 3Mb throughput using a smartbits and IMIX.

    I did get about 5.75Mb throughput with 1500byte packets on the 10Mb WIC card
    but then how many networks do you know of that only have 1500 bytes packets
    only.

  9. True - It might be useful for POS where you get remote troubleshooting and
    single vendor maintenance contracts.
