hcxStuSrcIpAddrUserMacAddr
Module: COM21-HCXSTU-MIB
OID (symbolic): COM21-HCXSTU-MIB::hcxStuSrcIpAddrUserMacAddr
OID (numeric): 1.3.6.1.4.1.1141.2.52.1.1.4
Node type: OBJECT-TYPE
Type: MacAddress
Access: read-write
Description: allowable MAC Address for ComPort. Default is 0:0:0:0:0:0
What is hcxStuSrcIpAddrUserMacAddr?
This read-write MacAddress specifies the allowable MAC address expected on the user side for this source-IP filter entry, defaulting to 0:0:0:0:0:0, per the description. An admin sets this to bind a specific customer-premises device's MAC address to the allowed source IP, tightening the ARP/source filter beyond IP address alone. For example, an admin populates hcxStuSrcIpAddrUserMacAddr with the customer's router MAC address so spoofed traffic using the right IP but a different MAC is still caught by the filter.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1141.2.52.1.1.4 snmpwalk -v2c -c public <target> COM21-HCXSTU-MIB::hcxStuSrcIpAddrUserMacAddr
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1141.2.52.1.1.4.1 snmpget -v2c -c public <target> COM21-HCXSTU-MIB::hcxStuSrcIpAddrUserMacAddr.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.1141.2.52.1.1.4.1 s <value>
