EC-5-NOPAGP: Invalid EC mode. PAgP not enabled.

Explanation This message means that PAgP is not included in the IOS image and that the EtherChannel mode cannot be set to desirable or auto.

Response Obtain an image with PAgP included, or set the mode to on by using the channel-groupchannel-group-numbermode on interface configuration command.

EC-5-STAYDOWN: no-shut not allowed on [chars]. Module [dec] not online.

Explanation This message means that an interface with an EtherChannel configuration cannot be enabled by using the no shutdown interface configuration command. It is a member of an EtherChannel group, and that EtherChannel group has been administratively shut down. The interface has an EtherChannel configuration, but no information is available yet about its port channel.

Response No action is required. Wait until the module is online to determine the port-channel setting of the EtherChannel.

EC-5-UNBUNDLE: Interface [chars] left the port-channel [chars].

Explanation This message means that the listed interface left the specified EtherChannel. The first [chars] is the physical interface, and the second [chars] is the EtherChannel.

Response No action is required.

EC-5-UNSUITABLE: [chars] will not join any port-channel, [chars].

Explanation This message means that one of the interfaces cannot join the EtherChannel because it is configured for PortFast, as a VLAN Membership Policy Server (VMPS), for 802.1X, as a voice VLAN, or as a Switched Port Analyzer (SPAN) destination port. All of these are unsuitable configurations for EtherChannels. The first [chars] is the interface name, and the second [chars] describes the details of the unsuitable configuration.

Response Reconfigure the port; remove the unsuitable configuration.

ETHCNTR Messages

This section contains the Ethernet controller messages. These messages are a result of a failure of the switch software when trying to program the hardware. Most of these errors lead to incorrect switch behavior, and you should call your technical support representative.

ETHCNTR-3-HALF_DUX_COLISION_EXCEED_THRESHOLD: Collision at [chars] exceed threshold. Consider as loop-back.

Explanation This message means that the collision at a half-duplex port exceeded the threshold and that the port is considered to be in the loop-back state. [chars] is the port.

Response No action is required.
