2610 Ethernet port speed

I have a 2610 router.  How can I tell if the built-in ethernet port is only a 10BASE-T or if it's a 10/100 port?  If it's only 10BASE-T, can I upgrade it to 10/100?

Thanks,

Gregg

It's 10, and cannot be upgraded. The router would not cope with more traffic anyway.

According to Table 1 in: http://www.cisco.com/en/US/prod/collateral/routers/ps259/prod_qas0900aecd802a9470_ps5854_Products_Q_and_A_Item.html, the 16 FastEthernet port is supported in 2600 series.  But as Paolo noted, a 2610 can't really can't cope with 100 Mbps.

If it is return Fast ethernet it must be 100 Base -t

Thanks

2610 Ethernet port speed

Thank you Paolo, Joseph, and Srinivasa.

  1. Is there a command I can issue on the 2610 router (e.g. a SHOW command?) that will tell me what kind of ports I have -- 10Base-t, 10/100, etc. and if they are half or full duplex?
  2. You say it cannot handle 100mbps traffic -- It won't have 100mbps of traffic, but can it handle 50 or 70mbps (that's what I expect)?  What's the bottle neck?
  3. If this router won't handle 50-70mbps of traffic, what router should I replace this with?  Would a 2620 router be able to handle the traffic?  I believe it has a 10/100 port standard.
  4. The 2610 has 2 WIC ports ... can I install 10/100 cards in these slots?  Which card would I get and can I assign them such one is the WAN side and the other is the LAN side?

We are a small ISP, local ISP and this handle pure internet traffice.

Thanks,

Gregg Smith

Re: 2610 Ethernet port speed

You can use show interface or read a data sheet to confirm.

What I meant to say, is that a 14 yrs old router will not handle 10 Mbps, let alone more than that.

You should look at a 1941 ISR G2 or better for that. Older models are obsolete and useless.

The bottleneck is the performance of the 2610's CPU is not sufficient for 100 Mbps.  I've attached a Cisco performance sheet for various models.  Take the Fast/CEF Switching performance and divide by 4 to provide a rough estimate of how much bandwidth the router might handle.

Hi,

for .1 the command will be show interface capabilities

Re: 2610 Ethernet port speed

Thanks again Paolo and Joseph,

I looked at the performance sheet ... so are you saying that if I have a 100mpbs connection to the internet, then I need the Fast/CEF to be 400Mbps (you said divide by 4)?  I don't see many that can do this.  Even the 1941 ISR G2 is rated at 153.08 -- so can it only handle 38Mbps of throughput?  Am I reading this chart correctly? 

I ran a SHOW INTER and only get the following -- nothing about port speed or type of duplex :-(  Any other commands that might work?

I want to make sure I'm looking at this correctly and get the network sized properly ... so sorry for all the Q's.

Re: 2610 Ethernet port speed

The new circuit coming in is fiber --- it's 30megs now but can be turned up to 100megs.  I don't see going over 50megs anytime in the near future.

I had another idea. I have a Cisco WS-C3550-24-PWR Swich connected to the 2610 router ... can I simple remove the router and use just this switch?  Is it capable of this?

Thanks,

Gregg

Re: 2610 Ethernet port speed

It is capable of handling the circuit, but chances are you will need the features of a true router, not a first generation layer 3 switch.

Re: 2610 Ethernet port speed

Thanks Paolo -- I hear ya!

I still want to make sure I get the right router ... Joseph sent the Cisco Performance Sheet and he said that I need to look at the Fast/CEF Mbps data and divide by 4 for tru throughput.   So I assume I need a router that's capable of 400Mbps minimum ... correct?  I don't see many that can do this.  Even the 1941 ISR G2 is rated at 153.08Mbps -- so can it only handle 38Mbps of throughput (divide by 4?)?  Am I reading this chart correctly?

Theres your bandwidth.....You should consider logging on the router and doing a clear counters, I notice a fair number of CRC errors. do a clear counters and then a show interface about an hour after that....there could be some underlying issues.

For the record, Paolos recomendation is pretty rock solid, In fact I would be tempted to go up a notch on the router.

Don't use a switch, you need a router.

Re: 2610 Ethernet port speed

Thanks.

What router would your recommend?   I only need 1 10/100 WAN port and 1 10/100 LAN port ... and I need to be able to handle up to about 70mbps  ... possibly 100mbps over the long run of throughput.  I'm thinking something on Ebay ... I have a tight budget, so whatever will work for the least money :-)

Thanks,

Re: 2610 Ethernet port speed

Based on that swag, MAYBE a high end 2800.... If you go to the cisco web page select routers  and branch there is some "hint' at the performance numbers for each model. Given what you have stated, the 29xx is listed at topping out at 75Mb....that pushes you into 3900 terrritory. You could scout around for an old 7200.....but let the buyer beware.
