Chapter 2 Message and Recovery Procedures ETHCNTR Messages 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 and lead to incorrect switch behavior. Error Message ETHCNTR-3-HALF_DUX_COLLISION_EXCEED_THRESHOLD: Collision at [chars] exceed threshold. Consider as loop-back. Explanation This message means that the collisions at a half-duplex port exceeded the threshold, and the port is considered as a loopback. On switches that support Power over Ethernet (PoE), this message might be displayed when a device that can be powered by either a PoE switch port or by AC power is not being powered by an external AC power source and is connected to a port that has been configured with the power inline never interface configuration command. [chars] is the port where the threshold was exceeded. Recommended Action On switches that support PoE, remove the device or configure the port by entering the power inline auto, shutdown, and no shutdown interface configuration commands. No action is required on non-PoE switches. The port goes into error-disabled mode until the problem is resolved. Error Message ETHCNTR-3-LOOP_BACK_DETECTED: Loop-back detected on [chars]. Explanation This message means that a loopback condition might be the result of a balun cable incorrectly connected to a port. On PoE switches, this message might appear when a device that can be powered by either a PoE switch port or by AC power is not being powered by an external AC power source and is connected to a port that has been configured with the power inline never interface configuration command. [chars] is the interface name. Recommended Action On non-PoE switches, check the cables. If a balun cable is connected and the loopback condition is desired, no action is required. Otherwise, connect the correct cable, and then enable the port. On PoE switches, remove the device, or configure the port by entering the power inline auto, shutdown, and no shutdown interface configuration commands. Error Message ETHCNTR-3-NO_HARDWARE_RESOURCES: Not enough hardware resources. Shutting down [chars]. Explanation This message means that there are too many VLANs and routed ports configured. [chars] is the short interface name, such as Gi1/0/1, or the VLAN name, such as VLAN0002. Recommended Action Reduce the total number of VLANs and routed ports to less than 1023. To preserve configuration and connections across reboots, save the configuration. 78-16184-04 Catalyst 3750 Switch System Message Guide 2-23

Message and Recovery Procedures
ETHCNTR Messages
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 and lead to incorrect switch behavior.
Error Message
ETHCNTR-3-HALF_DUX_COLLISION_EXCEED_THRESHOLD: Collision at [chars]
exceed threshold. Consider as loop-back.
Explanation
This message means that the collisions at a half-duplex port exceeded the threshold, and
the port is considered as a loopback. On switches that support Power over Ethernet (PoE), this
message might be displayed when a device that can be powered by either a PoE switch port or by
AC power is not being powered by an external AC power source and is connected to a port that has
been configured with the
power inline never
interface configuration command. [chars] is the port
where the threshold was exceeded.
Recommended Action
On switches that support PoE, remove the device or configure the port by
entering the
power inline auto
,
shutdown
, and
no
shutdown
interface configuration commands.
No action is required on non-PoE switches. The port goes into error-disabled mode until the problem
is resolved.
Error Message
ETHCNTR-3-LOOP_BACK_DETECTED: Loop-back detected on [chars].
Explanation
This message means that a loopback condition might be the result of a balun cable
incorrectly connected to a port. On PoE switches, this message might appear when a device that can
be powered by either a PoE switch port or by AC power is not being powered by an external AC
power source and is connected to a port that has been configured with the
power inline never
interface configuration command. [chars] is the interface name.
Recommended Action
On non-PoE switches, check the cables. If a balun cable is connected and the
loopback condition is desired, no action is required. Otherwise, connect the correct cable, and then
enable the port. On PoE switches, remove the device, or configure the port by entering the
power
inline auto
,
shutdown
,
and
no shutdown
interface configuration commands.
Error Message
ETHCNTR-3-NO_HARDWARE_RESOURCES: Not enough hardware resources.
Shutting down [chars].
Explanation
This message means that there are too many VLANs and routed ports configured.
[chars] is the short interface name, such as Gi1/0/1, or the VLAN name, such as VLAN0002.
Recommended Action
Reduce the total number of VLANs and routed ports to less than 1023. To
preserve configuration and connections across reboots, save the configuration.
