In one of our offices we have a DSL router connected to our Pix. We are implementing a T1 and I configed the router. The T1 is connected to the router and I can get in. But when we go to connect the router to the pix the link lights don't come on and the FastEthernet is up, but line protocol down. The encapsulation on the Serial is PPP and serial and line are up. We have used cross over and straight through cables (many of each). Here is the sh int
FastEthernet0/0 is up, line protocol is down
Hardware is AmdFE, address is 0012.d967.7ce0 (bia 0012.d967.7ce0)
Internet address is 66.x.x.x/30
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Auto-duplex, Auto Speed, 100BaseTX/FX
ARP type: ARPA, ARP Timeout 04:00:00
Last input 2d01h, output 00:00:03, output hang never
Last clearing of "show interface" counters never
Any help would be GREATLY appreciated.

Did you check that the PIX port connected to the 2600 is properly configured. It is in shutdown state by default.
Hope this helps,

I wouldn't think that the port would be in shutodwn mode since it is already connected to the DSL router and every thing is up. If I am wrong in thinking that please let me know.

I was referring to the port on the FW not on the 2600. Please make sure the port on the PIX facing the port fa0/0 on the 2600 is not in shutdown state and that it is configured for auto-negotiation since that was is set on the 2600 FE interface.
Hope this helps,

Again I really appreciate your help on this. I was referring to the PIX too. Here is what is there (it is currently connected to the DSL router)
interface ethernet0 "outside" is up, line protocol is up
Hardware is i82559 ethernet, address is x.x.x
IP address x.x.x.x, subnet mask 255.255.x.x

Thanks!

the PIX is configured for 100Mbits, full duplex, where as the 2600 is configured for auto negotiation.
Change ethernet0 on the PIX to auto negotiation with the following command and it should fix it.
interface e0 auto
Hope this helps,

Ok, I did that on the pix but nothing changed on the sh int (MTU 1500 bytes, BW 100000 Kbit full duplex). Was it supposed to? Also I am assuming that once we plug the pix into the router the line protocol will automatically come up, correct? Granted everything is configured right...
Thanks

The values in the "show int" on the pix would remain the same if the negotiation happens correctly with the 2600.
You are correct about your second statement. Assuming everything is configured properly the interface should come upo right away.
Do you have a crossover cable between the PIX and the 2600 now?
If so the other thing you could try is to configured both the PIX and 2600 manually to 100Mbps anf Full Duplex.
Hope this helps,
