| Ok so what is the difference between the bolded bits?
This is on a 1005 Router

Whats the meaning of QUICC & HD64570 and why can I not get them to talk using a V.35 cable or a DB60-DB60 crossover cable using HDLC?
Any guru's out there know  | |
| Wavy Davy 2002-01-26, 11:44 am |
| Hi Yeti,
Your 1005 needs a no shutdown for starters. No ideas on the QUICC. I wonder if the HD# is just a hardware number of the board? I wanna know too now.
Ciao,

|  Yo Yeti
I got nothing better to do - finish this shift in 35 minutes - so I look these up on the Cisco site. Here's the result:
Processor>> Motorola QUICC 68360 at 33 MHz
HD>> HD64570 serial controller
Looks like the manufacturers's equipment type numbers.

| I believe those are the controller chips that handles serial communications for the router's interfaces...kinda like what a UART is to a modem.
In addition to what Davy posted, it looks as though you don't have an IP address assigned to your serial port on the 1005.
Hope this helps. | |
| Hippo 2002-01-26, 12:48 pm |
|
The IP address of the serial is visible under the command 'show IP int serial 0'.
Unless Yeti has decided to use the 'ip unnumbered' command.

| Ok lads,
I fed these commands in to the respective routers and I dont think they liked it much  I was almost tempted to feed them to the bin  :
-------------------------------------
1005: DTE
conf t
routing rip 2
int s0
ip address 192.168.1.1 255.255.255.252
no shut
2501: DCE
conf t
routing rip 2
int s1
ip address 192.168.1.2 255.255.255.252 
clock rate 200000
no shut
-------------------------------------
Ok 1005: sh int s 0
Serial0 is down, line protocol is down

Ok 2501:
2501Lon#sh int s 1
Serial1 is down, line protocol is down
Hardware is HD64570
Description: connected to 1005

6 carrier transitions
DCD=up DSR=up DTR=down RTS=down CTS=up
2501Lon#
---------------------------------------------
For about 15 seconds they both show(where "x" is the respective serial interface"):
Serialx is up, line protocol is up
then revert to:
Serialx is down, line protocol is down
Damnd annoying if you ask me...I have checked the cable on my other routers and its 100% ok. So it has to be something with the 1005, since the 2501 was part of my 6 Router pod and works ok with them.
Now where did I put that 14Lb sledge hammer....... | |
| Wavy Davy 2002-01-26, 3:50 pm |
| Hi Yeti, am I right in assuming the 1005 s0 and the 2501 s1 interfaces are connected? If so, the ip address is the same on both of them. Try a different ip address in the same subnet and see what happens.
Wavy | |
| Yeti-GBR1 2002-01-26, 4:36 pm |
| Well spotted, actually it was a typo here, there corected above now
Yip tried all thatd..hence the post...pls give me some credit  | |
|

Yeti
Some things to try:
Do a 'show controllers serial x' on your serial interfaces and scroll down until you find an entry that looks like 'DTE V.35 etc,,,,'. This will confirm that the interfaces are set for DTE or DCE.
Is the cable you are using the correct way round - what I mean is - does it have a DTE and a DCE end.
Clear the counters on both routers, I don't like the look of the 1781 input errors and the 4883 interface resets on the 2501 router.
Check your routing table - 'show ip route'. Is there a route between the two routers in the table?
Apart from that, I don't what else to suggest just yet, but I am here 'till 7pm if you want, and I have access to Cisco routers in a LIVE network.
HTH

| You will never guess what I did....
I got the 1005 working!!!!! (Yip I even managed to amaze myself )
All I did was:
---------------------------------------------
Router>enable
Router#erase start
Router#reload
---------------------------------------------
Then manually added the required commands, looks like there was a conflict of some corruption of something in the original startup-config.cfg file.
Yeeeeeeeeeeeeha... man that feels good...on to the next brain teaser | |

| A CCIE once told me "never spend more time trying to fix something than it takes to reconfigure it from scratch"
He found this out the hard way on his first CCIE lab exam. |
