2600 Series 10/1000

[TheGeekGirl]

Greetings!

I am still getting my brain around all of a nuances of my routers.

We are upgrading our incoming Internet service from 30 Mb 10/100 to 100Mb 10/1,000.

Will my 2600 series router support the 10Mb 10/1,000 traffic from my new modem?

Do I need to change my interface speed from 100 to 1,000? 

I to be sure my router will support the upgrade.  Thank you in advance.

Nancy

Hi nancy,

As per my understanding, you want to upgrade your isp bandwidth to 100mbps with 10/1000 ratio, can you confirm this?

If yes then i think you can use the current interface (your fastethernet interface). But im suggesting you to monitor that interface, if you find the interface load is full, or you find some error on the show interface command, then i think you may proceed with the interface upgrade.

Handoko,

Yes we are upgrade t 100mbps with 10/1000.

Do I need to change the speed on the interface?

Thank you,

Nancy

I believe your current speed for that interface is 100mbps, so you dont need to change the speed.

Thank you Handoko!  I will watch for network congestion.

You cannot use an old 2600 router for high speed internet access, because it doesn't have enough performances. See attachment.

Will my 2600 series router support the 10Mb 10/1,000 traffic from my new modem?

I agree with Paolo's post.  You don't need a new modem.  You need a new ROUTER that can push 10 Mbps of traffic, full duplex.

hi paolo & leo, thanks for joining us here.

as im aware of 2600 is quite old router, but the internet traffic is using 1/100 ratio based. as per my understanding if we subscribe for 10mbps link, at the ISP side its actually 10mbps use by 100 subscriber, means if the other 99 subscriber are off, then we can get the actual 10 mbps link.

based on this understanding, im suggesting that nancy can go ahead with the upgrade, but with monitoring the interface load & the router performance.

but, if my ratio based internet traffic understanding was false,  means nancy will use full 100mbps internet link 1/1 ratio based, im totally agree with both of you.

regards,

ps: nice docs you have there paolo.

New router is on order.  Thank you for your help everyone.
