Cisco :: Interface Status Connected But No MAC?
Feb 18, 2011
On my Switch (3750), i have a host connected. Checked the interface status and it shows as "connected". However, when i tried checking the MAC connected to that interface, its not showingI have my Switch (3750) connected to a Router (3845). On the Switch, i have a printer connected in an interface. I am seeing the Printer's MAC associated with the switch port. However, when i checked the ARP table; no entry seen for the Printer's MAC. What are the possible reasons for this? We have several same kind of devices connected to network and they are fine.

I have cisco router 887VA.Question is when i connect that WAN port ( eth0) with any switch or laptop/pc i do not see the port in up state. What can be the reason.I have done "no shutdown " on interface level and there is no configuration on interface except the IP address , but it show " up down "state even the port is connected to some device. ( Is the port is faulty or some other reason).As per my concept it should show up state when we connect to some device ( Like router / switch / laptop).

We have two autonomous access point 1142 series running 12.4(21a)JA1 and randomly the Dot11Radio0 interface goes into reset/down state. At first I thought it was something related to power consumption issue on the switch, but looking at the remaining (w) I have plenty.

There was a big storm last night, and when I woke up I found that I couldn't connect to the internet. I have my computer plugged into the cable modem. The Windows network status says "Not connected, No connections are available". The onboard NIC that I had been using is no longer showing up in the device manager. I figured lightening might have knocked it out, even though my computer is behind a UPS and surge protector, so I bought a PCI ethernet card. This installed correctly and is showing up in the device manager, but I'm still getting the same error. When I unplug the ethernet cable, there is no change in the status.

So I'm trying to fix gateway laptop running Vista. The computer can connect both wired and wirelessly to the internet just fine. Sadly that's all it does. It doesn't let you use IE/Firefox/Skype or video games or anything. Every program acts like you're not connected. All signs seem to point towards it working just fine. I'm at a loss and can't figure out what's wrong with it.
Also, the internet works just fine if you start in safe mode with networking. You can use IE/Firefox just fine. I've tried turning off proxies and such but there aren't any as far as I can tell.

I would like to know something I have experienced quite often these last couple of weeks at my own offices as well as at some of my clients, on machines all running XP Professional, most with SP3 installed.
Sometimes it happens that only one pc at a time would have no physical connectivity to any outbound services like the internet, or any connection to another pc or the server running SBS 2003 for that matter, although the Network Status in the bottom right hand corner says it is connected, even at 100Mbs.
When opening Network Connections and I view the status of the LAN connection, it shows that packets are being sent and received, but I am not even able to ping another IP on the network, timing out every time.
The only solution to the problem seems to be "repairing" the network connection, and then all works fine again.
I would like to know what might be causing this in the first place and also what exactly a "network connection repair" is actually repairing? The reason I am asking is that I would like to find out if it might be a sign of any hardware starting to malfunction or anything in that regard, so that one could be in the clear about what to possible expect in the future.

I've configured a lot vpn server for 857/1800, etc. But this has never happened.I configured 881 as VPN server using CP.Shared key, local group and local user authetication with split route.Local pool 192.168.100.1-254? I have acl for telnet which allows local pool IPs.I have acl to deny local network to local pool IPs for NAT.I've deleted the whole settings and re-run the wizard. It's still the same thing. I can connect from the VPN Client, but no traffic going through. The problem to me is isakmp with DPD. But why it is dead? Why no response from the server? If it is an error, why connection has no problem.

On one of our routers (running bgp and ospf), we are redistributing ospf to bgp. This router has a loopback interface which is advertised in ospf.
Router#sh ip route 10.22.0.24
Routing entry for 10.22.0.24/32
Known via "connected", distance 0, metric 0 (connected, via interface)
Redistributing via bgp 64999
Routing Descriptor Blocks:
* directly connected, via Loopback11
Route metric is 0, traffic share count is 1
I am confused about "Redistributing via bgp 64999" part.....Under router bgp, we are redist only ospf and static routes, but using route-maps like this:
redistribute static route-map STATIC2BGP
redistribute ospf 1 route-map OSPF2BGP
Obviously it won't match redistribute static because it is not static, but connected interface...And 10.22.0.24 does not appear in match statement in route-map OSPF2BGP, how is it still shown as "Redistributing via bgp 64999"?

I have a 1801 router connected to a 3550 switch with a regular 802.1q trunk, and I am curious as to what may be causing the unknown protocol drops on the connected router interface.
The switch is without any configuration at all except the following for the trunk configuration on the interface connecting to the router.
Switch:
-interface FastEthernet0/1
-switchport trunk encapsulation dot1q
-switchport mode trunk
Router:
-Interface FastEthernet8
-switchport mode trunk
There is nothing connected to the switch other than the router so the dropped traffic must be originating from the switch itself.The unknown protocol drop counter on the router increments by one every 30 seconds, and I tried using a packet sniffer but nothing noticeble showed up.
I read elsewhere on these forums that it might be udld, but that is not enabled by default, and just to be sure I tried disabling it on the interface and as expected it said it was not enabled, so I am ruling that one out.I also read that it could be because the router is recieving traffic from other protocols than IP, but I do not see how it applies in this case.
what does a 3550 send every 30 seconds that my 1801 does not understand?Could it have something to do with STP?

requesting information via SNMP from my two stacked C3750X, running IOS 12.2(55)RE5. The stack is up and running and everything is just fine. There are three PowerSupplies installed with a PowerStack, also running like expectet.My problem ist to get the status-information about the chassis-fans. I couldn't find any information about the OID and the search results only in some non-useful information about the MIBs from Cisco which delivers only three information about installed fans (and fan-containers), so I guess these are the information about the fans included within the powersupply?! The chassis-fans are installed and the LEDs are green for all four fan-mounts, up and running.

I have a number of users who are failing wireless authentication. Using the troubleshooter i notice that its show message that Active Directory servers are not available. Under the Identity stores when i check on the connection status it shows disconnected. When i click on Test connection it shows successful. This ACS is a secondary. It has happened before and i removed it from the ACS cluster, rebooted it and rejoined it. Ran test connection and it showed "CONNECTED". Now it keeps showing disconnected.

I have a Cisco ASA 5505 and I have my internal and external interfaces configured but I currently cannot ping from the inside to an IP Address on the outside. I had this setup and working and I have another set of equirement that I am replacing that is working with my service provider so I know it is a configuration issue. When I ping 4.2.2.2 for example I get:
Destination host unreachable
Do I need to add a static route from my inside interface to my outside interfaces?
