R3102-R3103-HP 6600/HSR6600 Routers Layer 2 - WAN Command Reference Guide

Examples

# Enable OAM F5 Loopback detection on PVC 1/32, and set the transmission interval of OAM F5

loopback cells to 12 seconds, set the retransmission detection up-count to 4, down-count to 4, and

retransmission period to 1 second.

oamping interface

Use oamping interface to send OAM cells over the specified PVC on the specified ATM interface so as

to check the link state. If no response is received within the specified time, the link is bad or so busy that

packets are lost.

Syntax

oamping interface atm interface-number pvc { pvc-name | vpi/vci } [ number timeout ]

Parameters

atm interface-number: Specifies an ATM main interface by its number.

pvc-name: PVC name, a unique string of 1 to 16 characters on ATM interface, case-insensitive. The name

cannot be the same as a valid VPI/VCI pair value. For example, the name 1/20 is not allowed.

vpi/vci: VPI/VCI pair. VPI is short for virtual path identifier, and its value range is 0 to 255. VCI is short

for virtual channel identifier, and its value range varies by interface type. HP recommends not using VCI

values from 0 to 31, because they are reserved for special purposes. For more information about the

value range, see Table 3.

mber: Specifies the number of OAM cells to be transmitted consecutively, in the range of 1 to 1000.

The system default is 5.

timeout: Specifies the OAM response timeout period in the range of 1 to 30 seconds. The system default

is 2 seconds.

Examples

# Check the link state of PVC 1/32 on interface ATM 1/0/1, sending three cells and setting timeout

period to 1 second.
