Re: serial is down line protocol is down Could you please check you set the clock on the DCE side. Do a show controllers for the interfaces on each side of the link. Fastethernet 0/24 is down line protocol is. Device or a pc. I have gone to that particular interface say fa0/24 it show fa0/24 is down line protocol is down. Serial0/0 is down, line protocol is down Hardware is PQUICC with Fractional T1 CSU/DSU Internet address is 192.168.1.1/30 MTU 1500 bytes, BW 1536 Kbit, DLY 20000 usec. Fastethernet 0/24 is down line protocol is down(notconnect) by mjhundraindra 10 years ago In reply to fastethernet 0/24 is down. So, even u type command no shut, it still down. Yamaha Diagnostic Software Driver there. No physical light show up on that port. Futuristic City 3d Wallpaper Screensavers.

I wonder what can cause that the first line output of the command 'show interfaces' will be: 'fastEthernet is up, line protocol is down'. Cisco ethernet interfaces are normally down / down if they don't have a link. Driver License Or Id Card Delivery Status more.

If you're seeing up / down, the most likely causes are: • Cable fault • Speed mismatch (I personally haven't seen a duplex mismatch bring an intf up / down) • is cable that connected to the local interface, but not connected to the far end switch, will cause that situation? If the cable is bad. • is good cable that connected to both switches, but one switch had it's interface in 'administratively down' state, will cause that situation?

Is Down Line Protocol Is Down (notconnect)

I haven't seen that recently. For example, I have a c3560c in my lab and shutdown fa0/12. Then I connected a good cable between the fa0/11 and fa0/12 ports. Sw1#sh ip int brief i 0/1[1-9] FastEthernet0/11 unassigned YES unset down down FastEthernet0/12 unassigned YES unset administratively down down sw1# That said, I do have vague memories of seeing up / down when the remote interface was shut on other platforms in the past, but I don't remember seeing it recently If the cable is faulty, it could cause up / down status Testing your cabling: If you have a Cisco switch, you can test your cabling on the up / down interface like this. The following is good output for the command when nothing is connected to the other end of the cable. Sw1#test cable-diagnostic tdr interface Fa0/6 TDR test started on interface Fa0/6 A TDR test can take a few seconds to run on an interface Use 'show cable-diagnostics tdr' to read the TDR results.
