Internet Router Recommendation to support 2Mbps lease line and Netw Flow

utawakevou · ‎07-05-2004

We have a 128Kbps Internet connection to our ISP. It is a dedicated internet connection and we are using a 1720 series router for that Internet connection.

We are in the process of upgrading this internet link to 2Mbps and I believe the current 1720 serial port wont be able to support the 2Mbps connection.

We would also like to use net flow for our Internet traffic analysing purpose.

Im just after recommendation on the prefred Cisco router that will;

1. Cater for the 2Mbps lease line to our ISP

2. Be able to support IP net flow to enable us to analyse our Internet traffic.

Would prefer a 2600 series router

Your help would really be appreciated

Depending on the type of card, the 1720 would support up to 2mbps. The WIC-1T or WIC-2T for example supports up to this speed. Confirm the type of card you are using to connect to the ISP.

1720 also supports Netflow.

We are using a WIC-1T. And here is the current IOS version on my router:

1720 chassis, Hw Serial#: 853005124, Hw Revision: 0x601

Cisco Internetwork Operating System Software

IOS (tm) C1700 Software (C1700-Y-M), Version 12.1(5)T15, RELEASE SOFTWARE (fc2)

Hi,

We have upgrade our Internet link to 2Meg and doing bandwidth monitoring using cricket. I have notice that cricket is picking up the BW 1544 Kbit that is shown on the "show interface serial0" .

Does this means that my serial interfac can only go as far as 1544Kbps ?

Hi

Max Usable B/W details can be obtained from your ISP who can limit ur b/w at his end by applying rate-limit.

1544Kbps is the default value comes with the serial interface and most of the polling agents takes that as a ref while creating the config file.

you can manually alter it to 2048 and change the config file accordingly.

B/W command under interfaces are basically used by the routing protocols to calculate the best path to route the packets.
