swL2IGMPRobustness
Module: DGS3627-L2MGMT-MIB
OID (symbolic): DGS3627-L2MGMT-MIB::swL2IGMPRobustness
OID (numeric): 1.3.6.1.4.1.171.11.70.6.2.11.3.1.4
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 swL2IGMPRobustness?
Tunes how many query retries (the IGMP Robustness Variable) the switch performs to tolerate packet loss on the VLAN, defaulting to 2. Admins raise this on a lossy or heavily loaded VLAN so a single dropped query doesn't cause the switch to prematurely age out a multicast group.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.11.70.6.2.11.3.1.4 snmpwalk -v2c -c public <target> DGS3627-L2MGMT-MIB::swL2IGMPRobustness
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.11.70.6.2.11.3.1.4.1 snmpget -v2c -c public <target> DGS3627-L2MGMT-MIB::swL2IGMPRobustness.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.11.70.6.2.11.3.1.4.1 i <value>
