Here's a weird situation.
My PC intermittently reports an IP address conflict (drops connection and logs event ID 4199 in the windows system log:
"The system detected an address conflict for IP address 0.0.0.0 with the system having network hardware address 00-08-2F-07-D4-90. Network operations on this system may be disrupted as a result."
Here's the strangeness... That MAC address belongs to the switchport on the switch my PC is connected to:
TAC_A1_3850-48_STK#sh int g1/0/16
GigabitEthernet1/0/16 is up, line protocol is up (connected)
Hardware is Gigabit Ethernet, address is 0008.2f07.d490 (bia 0008.2f07.d490)
MTU 1500 bytes, BW 1000000 Kbit/sec, DLY 10 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
<SNIP>
Here's the config:
interface GigabitEthernet1/0/16
switchport access vlan 500
switchport mode access
switchport voice vlan 832
authentication control-direction in
authentication host-mode multi-domain
authentication port-control auto
mab
dot1x pae authenticator
spanning-tree portfast
spanning-tree bpduguard enable
end
What could cause this???
