Cisco 1941, question about ports

Posted on 2014-01-30
Last Modified: 2014-02-16
I have a new Cisco 1941 out of the box.  I am connected to it and I need to configure two ISPs and one LAN port.  The problem is, I do not know which ports are LAN and which ports are LAN.

I have three ports: 0/0    0/1   and  0/0/0

I need to know what port to make my LAN and which two to assign my static IPs from my ISP.

Can anyone tell me that simple thing?

It does not matter, how you connect them determines their function. Make sure to add descriptions to identify their function in the configs.

Most times the media type will determine which interfaces are WAN and which are LAN. For example, traditionally Ethernet has been a LAN type and T1/T3/DSL/POS/SONET interfaces to name a few have been WAN. Ethernet is now also a WAN protocol, so the answer is today its blurred.

Harbor is right.

I would use 0/0 and 0/1 for ISP connection and use 0/0/0 for LAN connection just to make it easier to identify.

Infamus answered directly and specifically.  I don't even understand what Harbor said.
