a3IPicmpMaskCtl
Module: A3COM-IPEXTNS-R5-MIB
OID (symbolic): A3COM-IPEXTNS-R5-MIB::a3IPicmpMaskCtl
OID (numeric): 1.3.6.1.4.1.43.2.6.6
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object determines whether this system replies to ICMP Address Mask request packets. If this object is set to mask (1), replies are sent. Otherwise, no replies are sent.
What is a3IPicmpMaskCtl?
This read-write INTEGER determines if the system replies to ICMP Address Mask Request packets used by legacy systems to discover subnet masks. Operators can enable mask replies (1) for legacy client support, though modern systems use DHCP; most disable this for security and simplicity. Modern networks typically set this to disabled to reduce diagnostic traffic and attack surface.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.2.6.6 snmpwalk -v2c -c public <target> A3COM-IPEXTNS-R5-MIB::a3IPicmpMaskCtl
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.43.2.6.6.1 snmpget -v2c -c public <target> A3COM-IPEXTNS-R5-MIB::a3IPicmpMaskCtl.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.43.2.6.6.1 i <value>
