I have a
Catalyst 4506 switch running IOS cat4000-i9s-mz12-25.EWA4.bin
The question I have is....
I have a Cisco Phone that is connected to an interface and a PC that is connected to the Phone. The Link speed should be 1000/full. When I run the command show mac-add dyn I do not see any MAC Address entries for the phone or the PC on that port and it is only running at 100/full but I do have network connectivity for both the PC and Phone.. On other ports I can see the MAC address for both the Phone and PC. What could the issue be?
Auto/Auto at the IP Phone and switchport should negotiate to 1Gb/FD if both link partners support such speed/duplex setting.
If the negotiation did not occur and both are set to Auto/Auto, replace the cable at both ends.
Also, try connecting the phone to another switchport.
