Hi,
I was practicing static routing and ran into a problem with the serial interfaces on router 2. I erased the startup-config and executed a reload. I configured serial0 interface and verified the ip address and ip route were correct. I issued the no shutdown command and ctrl Z to get back to the enable prompt. Using the show ip interface command I noticed serial0 was listed as "manual down."
Router 2 and 3 are the same model and IOS version. In the bootup process for router 2 I saw a message saying, NVRAM invalid, possibly due to write erase. Using IOS help, I ran some show commands to see if I could find anything out of the ordinary with the interfaces on this router. I did a show queue command on serial0 and nothing came up. On serial1 the router returned with Ethernet, Null and Serial information.
I noticed serial1 showed administratively down. So I removed the ip address and ip route from serial0 and configured it on serial1. Using a, show ip interface command, I noticed serial1 went into "manual" down.
Does any one have any advice on what the problem may be, or any other steps that may shed light on why the serial interfaces on this router will not open?
Thanks in advance...
