pppoeTCPMSSClampEnable
Module: WHISP-SM-MIB
OID (symbolic): WHISP-SM-MIB::pppoeTCPMSSClampEnable
OID (numeric): 1.3.6.1.4.1.161.19.3.2.1.83
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Enable or disable TCP MSS Clamping. Enabling this will cause the SM to edit the TCP MSS in TCP SYN and SYN-ACK packets. This will allow for a workaround for MTU issues so that the TCP session will only go up to the clamped MSS. If you are using PMTUD reliably, this should not be needed.
What is pppoeTCPMSSClampEnable?
Enables or disables TCP MSS clamping: when enabled, the SM edits the MSS in TCP SYN and SYN-ACK packets so sessions stay within the clamped size, a workaround for MTU problems. It is not needed if path MTU discovery works reliably.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.161.19.3.2.1.83 snmpwalk -v2c -c public <target> WHISP-SM-MIB::pppoeTCPMSSClampEnable
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.161.19.3.2.1.83.1 snmpget -v2c -c public <target> WHISP-SM-MIB::pppoeTCPMSSClampEnable.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.161.19.3.2.1.83.1 i <value>
