Sep 01, 2020
- Cisco Catalyst 3850 Series Switches
Known Affected Releases
Symptom: When a down interface is configured on Catalyst switch 3850 for a fixed speed and duplex value, the "show int status" command shows the correct speed, but it shows duplex as auto. This behavior is seen only on an unconnected port. Example: ####### CAT3850#show run interface gigabitEthernet 1/0/2 Building configuration... Current configuration : 62 bytes ! interface GigabitEthernet1/0/2 speed 100 duplex full end CAT3850#show interfaces status | include Gi1/0/2 Gi1/0/2 notconnect 1 auto 100 10/100/1000BaseTX Conditions: The problem is seen on down interface, but when the link is ?up?, it shows the correct settings.
