I have a 3560 stack(2 switches) ios-xe 16.x - latest ED<br />
and wlc 5585 v. 8.3.x<br />
and APs 2802 connected to the Switches via PoE port And aux port for lacp etherchannel.<br />
<br />
etherchannel and load-balance configured as per cisco on the switch,<br />
lag/lacp set enabled on wlc and APs<br />
<br />
when the etherchannel comes up, a console message &quot;cdp-4-duplex-mismatch&quot; on the switch appears indicating &quot;duplex-mismatch&quot; for the AUX port of the AP, meaning AP would make half duplex...WlC gui shows full duplex for AUX port but NO packets(might be a known bug as Switch shows packets)<br />
So port might work?? packets are flowing. bit mismatch remains....<br />
<br />
should i disable cdp on AUX port or ignoring message??

Cisco - Duplex mismatch between 3650 and AP2802/AUX-port

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
