Description

Output errors on this interface.

Contents

<aged-packets>—Number of packets that remained in shared packet SDRAM for so long that the system automatically purged them. The value in this field should never increment. If it does, it is most likely a software bug or possible broken hardware.

<carrier-transitions>—Number of times the interface has gone from down to up. This number should not increment quickly, increasing, for example, only when the cable is unplugged or the far-end system is powered down and up. If it does increment quickly (perhaps 1 every 10 seconds), then something is broken: the cable, the far-end system, or the PIC.

<hs-link-crc-errors>—Count of errors on the high-speed links between the ASICs responsible for handling the router interfaces.

<hs-link-fifo-underflows>—Numbers of errors on the high-speed links between the ASICs responsible for handling the router interfaces. The value in this field should always be 0. If it increments, either the FPC or the PIC is broken.

<mtu-errors>—Number of packets whose size exceeded MTU of interface.

<output-collisions>—Number of Ethernet collisions. The Gigabit Ethernet PIC and Fast Ethernet PIC support only full-duplex operation, so this number should always remain 0. If it is nonzero, there is a software bug.

<output-drops>—Number of packets dropped by the output queue of the I/O Manager ASIC. If the interface is saturated, this number increments once for every packet that is dropped by the ASIC's RED mechanism.

<output-errors>—Sum of the outgoing frame aborts and FCS errors.

<output-fifo-errors>—No documentation is available yet.

<output-hs-link-fifo-overflows>—No documentation is available yet.

<output-resource-errors>—Sum of B chip Tx drops and IXP Tx net transmit drops.
