i have a IPS 4260, running Version 6.0(5)E2.
I have noticed different duplex on the interface.
My understanding based on the logs below:
The interface below seems to be running in half duplex, but they are configured for full duplex.
-GigabitEthernet2/0
-GigabitEthernet2/3
-GigabitEthernet3/3
Is there any misconfiguration or a problem on my IPS?
extract from "show tech-support" command:
MAC statistics from interface GigabitEthernet2/0
Link Status = Up
Link Speed = 100
Link Duplex = Half
MAC statistics from interface GigabitEthernet2/1
Link Status = Up
Link Speed = 100
Link Duplex = Full
MAC statistics from interface GigabitEthernet2/2
Link Status = Up
Link Speed = 100
Link Duplex = Full
MAC statistics from interface GigabitEthernet2/3
Link Status = Up
Link Speed = 100
Link Duplex = Half
MAC statistics from interface GigabitEthernet3/0
Link Status = Down
Link Speed = N/A
Link Duplex = N/A
MAC statistics from interface GigabitEthernet3/1
Link Status = Down
Link Speed = N/A
Link Duplex = N/A
MAC statistics from interface GigabitEthernet3/2
Link Status = Up
Link Speed = 100
Link Duplex = Full
MAC statistics from interface GigabitEthernet3/3
Link Status = Up
Link Speed = 100
Link Duplex = Half
