gdcHdslT1AISLoopdownTime

Module: GDCHDSL-MIB

OID (symbolic): GDCHDSL-MIB::gdcHdslT1AISLoopdownTime

OID (numeric): 1.3.6.1.4.1.498.11.1.3.3.1.8

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This variable is used to set T1 AIS Loopdown Time

What is gdcHdslT1AISLoopdownTime?

Selects how long an Alarm Indication Signal (AIS) condition must persist before this T1 interface automatically drops an active loopback: inhibit, or 5/10/20/40/60 seconds. An administrator sets a nonzero timeout so a stuck loopback clears itself automatically once an AIS alarm confirms the far end has lost the signal.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.498.11.1.3.3.1.8
snmpwalk -v2c -c public <target> GDCHDSL-MIB::gdcHdslT1AISLoopdownTime

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.498.11.1.3.3.1.8.1
snmpget -v2c -c public <target> GDCHDSL-MIB::gdcHdslT1AISLoopdownTime.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.498.11.1.3.3.1.8.1 i <value>
