igsRobustnessValue
Module: DGS-1248T-B1-MIB
OID (symbolic): DGS-1248T-B1-MIB::igsRobustnessValue
OID (numeric): 1.3.6.1.4.1.171.10.76.6.22.1.16
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The Robustness Variable allows tuning for the expected packet loss on a subnet. If a subnet is expected to be lossy, the Robustness Variable may be increased. IGMP is robust to (Robustness Variable-1) packet losses.
What is igsRobustnessValue?
This tuning value (2-255, default 2) lets an admin make IGMP snooping more tolerant of packet loss on a lossy subnet; snooping can withstand this many minus one lost packets. An admin would raise this on a network with a flaky Wi-Fi or noisy segment to avoid falsely dropping multicast group membership.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.10.76.6.22.1.16 snmpwalk -v2c -c public <target> DGS-1248T-B1-MIB::igsRobustnessValue
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.10.76.6.22.1.16.1 snmpget -v2c -c public <target> DGS-1248T-B1-MIB::igsRobustnessValue.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.10.76.6.22.1.16.1 i <value>
