hi
Does someone know if it is possible to use the WIC (see below) with a cisco
"1721" router:
WIC-4ESW Cisco 4-Port Fast Ethernet Switch WAN Interface Card
see:
http://www.cisco.com/en/US/products/...0801c749d.html

In their doc they show the 1760 modell, so I was wondering if you could use
it on 1721.
Could someone tell me that plz?
If it is possible what are the ios requirements?

Many many thx

no, per the following.

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

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
Jasko

Yes.

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

Scott.

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.

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.

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