WIC 1T Working Correctly / Frame Relay Question?

ciscoman2012

So I've just set up my rack and starting to install the routers I've bought off eBay. I tried setting up a HDLC connection between one router and a FR router with a NM 4A/S in it. I also set up another HDLC connection between another router and the same FR Router.

The router with the WIC1T did not work successfully.

The router with the WIC2T did work successfully.

Same commands on each router, same commands on the FR router.

Is my WIC1T faulty? Is the "Conn" light supposed to light up after bootup like the WIC2T does?

**Last question: I know in the real world Routers by default act as DTE devices. That being said, the most logical explanation for the FR Router would be to have it set up to be the DCE and provide clock rate to the spoke routers. I bought all DTE to DCE cables. For my topology, that means my spoke routers will be DCE devices and the hub (FR Router) will be DTE. Will this be a problem? Will it affect my Frame Relay studies negatively in any ways?

Thanks for the help TE!

Might want to post the configs. Did you set the clockrates ?

Cables are good ?

What does show controller on each wic give you ?

Good chance to practice your debugging.

I'm 99% sure I set the clock rate. I will post up my configs later once I actually attempt to configure everything.

In general though, is it safe to say the Wic 1T lights up if there is nothing plugged in / the interface is shutdown/no shutdown? Like the Wic 2T does?

No my wic1ts and wic2ts only light up when connected

What does show controllers give you ?

Thanks for the help I will try this when I get back home with the lab.

It was confusing me since the Wic 2T is lighting up "Conn" before anything is even connected.

From your pic above it looks like your wic2t and nm4as is lighting up but not the wic1t.

Can confirm my nm4as lights up with nothing connected but not my wic1t or wic2t's.
I'd have to check the config to see what mode the serial ports are in.

Serial WAN Interface Card LEDs

Each serial WIC has one LED, labeled CONN for each port, which lights when the serial port is connected. When the port is in DTE mode, the CONN LED indicates that Data Send Ready (DSR), Data Carrier Detect (DCD), and Clear To Send (CTS) have been detected. When the port is in DCE mode, it indicates that Data Terminal Ready (DTR) and Ready To Send (RTS) have been detected.

Thanks the information. Yes, the NM 4 A/S and WIC2T are both lit up.

Both the WIC1T and WIC2T are setting the clocking, so I have them as DCE. I believe both WIC cards are no shutdown as well.

Once I have a bit more time I'm going to try and troubleshoot a bit more. Probably erase configs on both routers and start from scratch. Just was trying to figure out if WIC 1T is supposed to light up with nothing done to it (interface not open, no cable connected, no ip add assigned..etc)

erase the configs on two routers - don't forget you can backup/save configs via tftp once you have a network connection
copy run tftp
copy startup-config tftp

If you save them by date and what you were practising you have configs to compare against if
you want to go back and

if don't have a tftp server TFTPD32 : an opensource IPv6 ready TFTP server/service for windows : TFTP server
Just remember to make sure you setup a firewall port rule for it.

Then setup up a basic serial connection between them.

something like
router 1
Serial 0/0
no shutdown
ip address 10.10.10.2 255.255.255.0

router 2
Serial 0/0
no shutdown
clock rate 64000
ip address 10.10.10.3 255.255.255.0

Check all the serial interfaces (and T1) and cables - make sure everything works

Then set the encapsulation , then move on.
Can also unplug the cable and check that it goes down , then comes back up when you plug it back in

few commands to try once you have them connected

sh cdp
sh cdp ne/ne de
sh ip int bri
sh ip route
sh interfaces
sh version
sh ip protocols
sh protocols
sh arp
sh int status
sh run int fa0/0
show controllers
show controller _ _ _ _ _
show ip interface brief
show ip interface
show interface status
show interface description

Make sure it's not the routers slot as well. Swap the WIC-1T into the other router in the WIC-2T's slot, since the WIC-2T's slot is known good. If the WIC-1T works in that slot, you know it's not the hardware. If it doesn't work, then you've still go the possibility of a bad cable, unless you've already checked that.

And I understand why you may be screwed as far as the WIC-2T end having to set clocking if the smart serial connectors are the only side that provides DCE, but that doesn't track for the NM-4A/S, they both use the same connector, so you should be able to set the NM-4A/S to clocking and the WIC-1T to DTE

Fixed. I think I was just getting sloppy and making newb mistakes like thinking I was on the wrong serial port when I was really on another. I wasn't sure how it was numbered until I actually looked at the NM 4 A/S and realized I was picturing it numbered the wrong way.
