sonetAtmStatus

Module: Fore-SONET-MIB

OID (symbolic): Fore-SONET-MIB::sonetAtmStatus

OID (numeric): 1.3.6.1.4.1.326.2.2.1.1.4.1.1.1.17

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This variable indicates the ATM Status of the interface. The variable is a bit map represented as a sum, therefore, it can represent multiple defects simultaneously. The sonetAtmNoDefect should be set if and only if no other flag is set. The various bit positions are: 1 sonetAtmNoDefect 2 sonetAtmLCD Loss of Cell Delineation was detected. LCD is declared when a 'normal pointer value' is not found for eight consecutive frames.

What is sonetAtmStatus?

A bitmapped summary of ATM-layer defects on this port, where bit 2 indicates Loss of Cell Delineation (LCD, detected after 8 consecutive frames without a normal pointer value) and a value of 1 means no defect. An admin reads this alongside sonetAtmLCDs to see if cell delineation is currently failing.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.4.1.1.1.17
snmpwalk -v2c -c public <target> Fore-SONET-MIB::sonetAtmStatus

Get a specific instance (index 1):
