a3ComBrgDstSecCtl
Module: A3COM-BRIDGE-R3-MIB
OID (symbolic): A3COM-BRIDGE-R3-MIB::a3ComBrgDstSecCtl
OID (numeric): 1.3.6.1.4.1.43.2.9.1.12.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object is a security feature that allows the control of packets sent to specific destinations. If this object is set to forward (2), only those packets for destination addresses listed in the static forwarding table can be forwarded by this port. If this object is set to block (3), any packet destined for an address listed in the static forwarding table is blocked by 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 a3ComBrgDstSecCtl?
This read-write integer controls destination address filtering, allowing only frames to whitelisted (forward=2) or blacklisted (block=3) MAC addresses in the static table. This enforces security by restricting which devices can receive frames through the port, acting as a destination-based firewall. For example, setting this to 2 (forward) means only frames destined for MACs in the static table pass; all others are dropped.
Examples
