accIpsecSAConfigCopyDF
Module: ACC-IPSEC
OID (symbolic): ACC-IPSEC::accIpsecSAConfigCopyDF
OID (numeric): 1.3.6.1.4.1.5.1.1.81.3.1.1.9
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The handling of the DF bit on the sent encapsulating header based on the DF bit of the encapsulated header
What is accIpsecSAConfigCopyDF?
This field controls how the DF (Don't Fragment) bit is handled on encrypted packets: reset (1) clears it, set (2) always marks it, or copy (3) inherits it from the original packet. You need to set this correctly based on your network's MTU (maximum packet size) and whether your path supports jumbo frames. Setting it to copy (3) usually works best because it preserves the original packet's fragmentation intent.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5.1.1.81.3.1.1.9 snmpwalk -v2c -c public <target> ACC-IPSEC::accIpsecSAConfigCopyDF
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.5.1.1.81.3.1.1.9.1 snmpget -v2c -c public <target> ACC-IPSEC::accIpsecSAConfigCopyDF.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.5.1.1.81.3.1.1.9.1 i <value>
