swL2IGMPRobustness
Module: DES3550-L2MGMT-MIB
OID (symbolic): DES3550-L2MGMT-MIB::swL2IGMPRobustness
OID (numeric): 1.3.6.1.4.1.171.11.64.2.2.10.3.1.4
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 have a high loss, the Robustness Variable may be increased. IGMP is robust to (Robustness Variable-1) packet losses.
What is swL2IGMPRobustness?
Tunes how many IGMP packet losses the snooping implementation tolerates on this VLAN's subnet (default 2); raising it on a lossy subnet makes the switch retry more queries before deciding a group has no members, per RFC 2236's robustness variable.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.11.64.2.2.10.3.1.4 snmpwalk -v2c -c public <target> DES3550-L2MGMT-MIB::swL2IGMPRobustness
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.11.64.2.2.10.3.1.4.1 snmpget -v2c -c public <target> DES3550-L2MGMT-MIB::swL2IGMPRobustness.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.11.64.2.2.10.3.1.4.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> swL2IGMPRobustness.1
