a3ComBrgSrcSecCtl

Module: A3COM-BRIDGE-R3-MIB

OID (symbolic): A3COM-BRIDGE-R3-MIB::a3ComBrgSrcSecCtl

OID (numeric): 1.3.6.1.4.1.43.2.9.1.12.1.4

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This object is a security feature that allows the control of packets sent from specific source addresses. If this object is set to forward (2), this port will forward only those packets sent from addresses listed in the static forwarding table for this port. If this object is set to block, this port will block every packet sent by a station whose address is listed in the static forwarding table for this port. Note, these actions are taken by this port after it receives a packet from the network. This does not apply to packets it forwards to the network.

What is a3ComBrgSrcSecCtl?

This read-write integer controls source address filtering, allowing only frames from whitelisted (forward=2) or blacklisted (block=3) source MACs in the static table. This prevents rogue or spoofed devices from injecting traffic through the port, improving network security. Setting this to 2 (forward) allows only traffic from MACs listed in the static table for that port to pass through.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.2.9.1.12.1.4
snmpwalk -v2c -c public <target> A3COM-BRIDGE-R3-MIB::a3ComBrgSrcSecCtl

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.43.2.9.1.12.1.4.1
snmpget -v2c -c public <target> A3COM-BRIDGE-R3-MIB::a3ComBrgSrcSecCtl.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.43.2.9.1.12.1.4.1 i <value>
