Cisco Bug: CSCvs83963 - AppGig interface changed to down on "no iox"
Sep 03, 2020
- Cisco Catalyst 9300 Series Switches
Known Affected Releases
Symptom: AppGigabitEthernet1 interface is enabled automatically in 16.12.1 and later release. AppGigabitEthernet interface will respond to any ARP due to how internal Linux bridge is set up on the following subnet range: 10.2.x.x/16 10.3.x.x/16 10.0.x.x/16 The ARP response causes the DHCP pool starvation as DHCP server will interpret ARP responses as an indication that the offered IP address is already assigned and present in the network. Conditions: Cat9300L switch 16.12.1 or 16.12.2 or 16.12.3 release
