I have implemented 802.1X with ACS 5.3 and switches 2960 without problem.The thing is that one port transitioned into err-disabled and I dont know why.I dont have any logs to see what caused this.Is there a command to see why this happenedWhat do you think could cause this?

What could cause this log message and put the port in errdisable?
15w2d: %ETHCNTR-3-LOOP_BACK_DETECTED: Loop-back detected on FastEthernet0/22.
15w2d: %PM-4-ERR_DISABLE: loopback error detected on Fa0/22, putting Fa0/22 in err-disable state
15w2d: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/22, changed state to down

View 3 Replies View RelatedWe have a number of 3750 stacks used as access layer switches connecting Siemens VOIP phones and then a PC that connects to the phone.
For example if I plug PC A to the phone that connects to port 13 I pick up an IP addressand all works as predicted now if I plug in PC A to any other VOIP phone that connect to another port on the same switch it goes in error disable state ITs like the switch is holding my PC mac address and locks it down with the port which in my case is Gi2/0/13.
interface GigabitEthernet2/0/13
switchport access vlan 726
switchport mode access
[Code].....
I have a Catalyst 2950G when I activate the switchport port-security, but I want to empty the black list of mac address because every time I connect a device, the port is automatically désacative, here is the port configuration:
!
interface FastEthernet0 / 2
switchport access vlan 17
switchport mode access
switchport voice vlan 51
[code]....
I tried the following commands to clear the blacklist mac address of that port, but the problem is still relevant:
# Clear mac-address-table dynamic int fa0 / 2
# clear port-security all int fastethernet 0/2
# clear errdisable interface fa0 / 2 vlan
After reboot WLC , the switch port was err-disable , the cause is link flap after we reboot 3 times , the switch port link flap err-disable every time? We don't know why the WLC rebboot will cause it , it just normal action on device the WLC version is 7.4.100.0 link switch with access port , no port channel , no portfast.

Port Security - Port Is shut down
Err-Disable - Port goes into err-disable state (securedown)
HSRP - When HSRP standyby changes are detected
I need to receive emails with any of the able are triggered. What is the easiest way to do this? I know SNMP is the main option but I have never worked with SNMP and dont understand it too much.

The router 1841 is connected directly to the layer switch. the network diagram is below:
Office A --> Switch (L3) --> Router 1841 --> Internet --> Office B
However, when I transfer the file from Office A to office B, the speed very slow ( only around 40 kb/second), and there are an input error and CRC error:
Cisco-R1841#sh interfaces FA0/1
FastEthernet0/1 is up, line protocol is up

View 1 Replies View RelatedI'm thinking about restricting 802.11b devices on my wireless networks and was wondering what is the best way to do so. As far as I am aware I can do it by either selecting "802.11a/g only" as the radio policy for each WLAN (Not shure what effect this will have on 802.11n though) or by disabling the following data rates 5.5mbs and 11mbs.

The ASA has some concurrent session limitation that, I think, is related to xlate connections.
As my firewall is not performing any kind of NAT, is it possible to disabe xlate for some connections.

How can i disable dns doctoring on my Cisco 1921 router? Even if i use an external DNS my router facilitates me when i try to resolv addresses that are accessible externally and NATed through my router to the appropriate host. The router looks at its own NAT table and sees the IP i am trying to access and sends me right to the local IP. In my situation this is not good and i would like to disable this feature so that i can take the "outside" to this website.

If you do not change the default IP or default SSID for example, The WPS is disable by default. Once you change default IP and SSID for example, the WPS is then enabled. There is no Disable Option for WPS.

I use windows xp and a BT home hub 2.0, i had my wifi set up so i could enable and disable wifi at my leisure. However every now and then i don't get the option to disable the wifi, so i normally have to reset my default admin password and enter my own password to eventually re use the enable/disabled option. But now i can't even do that so i'm stuck with permanent wifi. I did briefly manage to get the disable/enable option back by reset hub to factory settings but now it has gone again. What can i do? On my home network page where it reads devices currently connected to your BT home hub it has no devices detected for wireless.
