R3303-HP HSR6800 Routers Layer 2 - WAN Command Reference

Default command level

2: System level

Parameters

frequency: Interval (in seconds) at which OAM F5 loopback cells are sent. The value range is 1 to 600.

up up-count: Specifies that the PVC goes up when the number of successive OAM F5 loopback cells

received correctly reaches the value specified by the up-count argument. The value range for the up-count

argument is 1 to 600, and the default is 3.

down down-count: Specifies that the PVC goes down when the number of successive OAM F5 loopback

cells that it fails to receive reaches the value specified by the down-count argument. The value range for

the down-count argument is 1 to 600, and the default is 5.

retry-frequency retry-frequency: Specifies the interval (in seconds) at which OAM F5 loopback cells

should be transmitted to verify a change in the PVC state (up/down). The value range is 1 to 1000. The

default is 1.

Usage guidelines

The oam frequency command is not applicable to the secondary PVCs of a PVC group.

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
