What is isdnN200?

This OID sets the maximum number of retransmissions (1–5) before the ISDN Layer 2 link is declared down and disconnected. Higher values tolerate noisy lines but delay failure detection; lower values fail fast but may drop good calls on lossy lines. A value of 3 means the system will retry 3 times before giving up.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.11.2.1.4
snmpwalk -v2c -c public <target> ACMIB::isdnN200

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.11.2.1.4.1
snmpget -v2c -c public <target> ACMIB::isdnN200.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.5.11.2.1.4.1 i <value>
