Description: Test Flags: SNMP-Traps, Encapsulation: ENET2 Protocol inet, MTU: 1500, Flags: None Addresses, Flags: Is-Preferred Is-Primary Destination: 10.115.107.192/29, Local: 10.115.107.193 Broadcast: 10.115.107.199 Meaning The sample output shows where the alarm and other errors might be occurring and any counters that are incrementing. The only alarm associated with Fast Ethernet or Gigabit Ethernet interfaces is the LINK alarm. A LINK alarm indicates a physical problem. To isolate where the physical problem might be occurring, conduct loopback testing. See “Checklist for Using Loopback Testing for Fast Ethernet and Gigabit Ethernet Interfaces” on page 611 for information on conducting a loopback test. NOTE: Since link status is polled once every second, some items that require fast link down detection, such as Multiprotocol Label Switching (MPLS) fast reroute, take longer to execute. Fast Ethernet and Gigabit Ethernet Counters Problem Table 48 on page 623 shows the major counters that appear in the output for the show interfaces fe-fpc/pic/port extensive and the show interfaces ge-fpc/pic/port extensive commands. These counters generally increment when there is a problem with a Fast Ethernet or Gigabit Ethernet interface. In the Counters column, the counters are listed in the order in which they are displayed in the output. Table 48: Major Solution Fast Ethernet and Gigabit Ethernet Counters Counter Input Errors: Errors Policed discards Drops L3 incompletes Description The sum of the incoming frame aborts and frame check sequence (FCS) errors. The frames discarded by the incoming packet match code. The number of packets dropped by the output queue of the I/O Manager application-specific integrated circuit (ASIC). The number of packets discarded due to the packets failing Layer 3 header checks. Copyright © 2012, Juniper Networks, Inc. Chapter 35: Investigate Fast Ethernet and Gigabit Ethernet Interfaces Reason for Increment The frames were discarded because they were not recognized or of interest. Usually, this field reports protocols that the Junos OS does not handle. If the interface is saturated, this number increments once for every packet that is dropped by the ASIC’s random early detection (RED) mechanism. This counter increments when the incoming packet fails Layer 3 (usually IPv4) checks of the header. For example, a frame with less than 20 bytes of available IP header would be discarded and this counter would increment. 623
