Cisco Bug: CSCvi02106 - Cisco 2800, 3800, 1560 APs: when connected to a Cisco Switch CDP-4-DUPLEX_MISMATCH log is seen
Jan 14, 2020
- Cisco Aironet 1850 Series Access Points
Known Affected Releases
8.3(134.79) 8.3(140.0) 8.3(141.0) 8.3(143.0)
Symptom: You might see "CDP-4-DUPLEX_MISMATCH" messages on a Cisco switch that refer to a port where a Wave 2 AP is connected. By default, these messages are logged every 60 seconds per port. This could cause the syslog buffers to fill up and lose more important messages. Conditions: Cisco 2800/3800 & 1560 Series access points connected to Cisco switchports with CDP enabled. Running 8.3 AP-COS - not 8.4 or above.
