Static ARP Table Entries Feature Guide for Routing Devices If the example configuration contains the top level of the hierarchy (or multiple hierarchies), the example is a full example. In this case, use the load merge command. If the example configuration does not start at the top level of the hierarchy, the example is a snippet. In this case, use the load merge relative command. These procedures are described in the following sections.
About the Documentation 2. Move to the hierarchy level that is relevant for this snippet by issuing the following configuration mode command: [edit] user@host# edit system scripts [edit system scripts] 3. Merge the contents of the file into your routing platform configuration by issuing the load merge relative configuration mode command: [edit system scripts] user@host# load merge relative /var/tmp/ex-script-snippet.conf load complete For more information about the load command, see the CLI User Guide.

Example: Configuring Static ARP Table Entries Configure two static ARP table entries on the router or switch’s management interface: [edit interfaces] fxp0 { unit 0 { family inet { address 10.10.0.11/24 { arp 10.10.0.99 mac 0001.0002.0003; arp 10.10.0.
CHAPTER 3 Network Interfaces Configuration Statements and Hierarchy • [edit interfaces] Hierarchy Level on page 9 [edit interfaces] Hierarchy Level The statements at the [edit interfaces interface-name unit logical-unit-number] hierarchy level can also be configured at the [edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number] hierarchy level. NOTE: The accounting-profile statement is an exception to this rule.

CHAPTER 8 Interface Diagnostics • Interface Diagnostics on page 109 Interface Diagnostics You can use two diagnostic tools to test the physical layer connections of interfaces: loopback testing and bit error rate test (BERT) testing. Loopback testing enables you to verify the connectivity of a circuit. BERT testing enables you to identify poor signal quality on a circuit.
Static ARP Table Entries Feature Guide for Routing Devices • Local—Useful for troubleshooting physical PIC errors. Configuring local loopback on an interface allows transmission of packets to the channel service unit (CSU) and then to the circuit toward the far-end device. The interface receives its own transmission, which includes data and timing information, on the local router's PIC. The data received from the CSU is ignored. To test a local loopback, issue the show interfaces interface-name command.
Chapter 8: Interface Diagnostics Table 10: Loopback Modes by Interface Type (continued) Interface Loopback Modes Usage Guidelines T1 and T3 Local, payload, and remote Configuring T1 Loopback Capability and Configuring T3 Loopback Capability See also Configuring the T1 Remote Loopback Response To configure loopback testing, include the loopback statement: loopback mode; You can include this statement at the following hierarchy levels: • [edit interfaces interface-name aggregated-ether-options] • [
Static ARP Table Entries Feature Guide for Routing Devices [edit interfaces interface-name interface-type-options] bert-algorithm algorithm; bert-error-rate rate; bert-period seconds; By default, the BERT period is 10 seconds. You can configure the BERT period to last from 1 through 239 seconds on some PICs and from 1 through 240 seconds on other PICs. rate is the bit error rate.
Chapter 8: Interface Diagnostics NOTE: The 12-port T1/E1 Circuit Emulation (CE) PIC supports only the following algorithms: all-ones-repeating Repeating one bits all-zeros-repeating Repeating zero bits alternating-double-ones-zeros Alternating pairs of ones and zeros alternating-ones-zeros Alternating ones and zeros pseudo-2e11-o152 Pattern is 2^11 -1 (per O.152 standard) pseudo-2e15-o151 Pattern is 2^15 - 1 (per O.151 standard) pseudo-2e20-o151 Pattern is 2^20 - 1 (per O.
Static ARP Table Entries Feature Guide for Routing Devices NOTE: BERT is supported on the PDH interfaces of the Channelized SONET/SDH OC3/STM1 (Multi-Rate) MIC with SFP and the DS3/E3 MIC.
Chapter 8: Interface Diagnostics These limitations do not apply to channelized IQ interfaces. For information about BERT capabilities on channelized IQ interfaces, see Channelized IQ and IQE Interfaces Properties. Starting and Stopping a BERT Test Before you can start the BERT test, you must disable the interface.
