Junos ® OS 12.3 Ethernet Interfaces Configuration Guide Table 48: Major Fast Ethernet and Gigabit Ethernet Counters (continued) Counter L2 channel errors L2 mismatch timeouts FIFO errors Output Errors Errors Collisions Drops Aged packets HS link FCS errors, FIFO errors Description Miscellaneous Counters Input DA rejects Output packet pad count 624 The errors that occur when the software could not find a valid logical interface (such as fe-1/2/3.0) for an incoming frame. The count of malformed or short packets. The number of first in, first out (FIFO) errors in the receive direction as reported by the ASIC on the Physical Interface Card (PIC). The sum of outgoing frame aborts and FCS errors. The number of Ethernet collisions. The number of packets dropped by the output queue of the I/O Manager ASIC. The number of packets that remained in shared packet SDRAM for so long that the system automatically purged them. The number of errors on the high-speed links between the ASICs responsible for handling the router interfaces. The number of packets that the filter rejected because the destination Media Access Control (MAC) address of the packet is not on the accept list. The number of packets that the filter padded to the minimum Ethernet size (60 bytes) before giving the packet to the MAC hardware. Reason for Increment This error increments when, for example, a lookup for a virtual LAN (VLAN) fails. The malformed or short packets cause the incoming packet handler to discard the frame and be unreadable. The value in this field should always be 0. If this value is not zero, cabling could be badly organized or the PIC could be broken. The Fast Ethernet PIC supports only full-duplex operation, so this number should always remain 0. If it is incrementing, there is a software bug. If the interface is saturated, this number increments once for every packet that is dropped by the ASIC’s RED mechanism. The value in this field should never increment. If it increments, it is probably a software bug or broken hardware. The value in this field should always be 0. If it increments, either the FPC or the PIC is broken. It is normal for this value to increment. When it increments very quickly and no traffic is entering the router from the far-end system, either there is a bad Address Resolution Protocol (ARP) entry on the far-end system, or multicast routing is not on and the far-end system is sending many multicast packets to the local router (which the router is rejecting). Usually, padding is done only on small ARP packets, but some very small Internet Protocol (IP) packets can also require padding. If this value increments rapidly, either the system is trying to find an ARP entry for a far-end system that does not exist, or it is misconfigured. Copyright © 2012, Juniper Networks, Inc.
Table 48: Major Fast Ethernet and Gigabit Ethernet Counters (continued) Counter Output packet error count CAM destination filters, CAM source filters Description Copyright © 2012, Juniper Networks, Inc. Number of packets with an indicated error that the filter was given to transmit. The number of entries in the content-addressable memory (CAM) dedicated to destination and source MAC address filters. Chapter 35: Investigate Fast Ethernet and Gigabit Ethernet Interfaces Reason for Increment These packets are usually aged packets or are the result of a bandwidth problem on the FPC hardware. On a normal system, the value of this field should not increment. There can be up to 64 source entries. If source filtering is disabled, which is the default, the value for these fields should be 0. 625
