Description: This object configure 'split horizon' switching between bridge Ports. - disable - normal (VLAN aware) bridge behavior. - enable - all packets, regardless their VLAN, coming from user side are blocked from being switched back to other user side bridge ports. - vlanBased - split horizon behavior is applicable only for specific VLANs, according to radBridgeDot1qVlanSplitHorizon.
What is radBridgeSplitHorizon?
This object controls how a bridge handles traffic between user-facing ports to prevent loops and manage VLAN-based network segmentation. When enabled in normal mode, packets from one user port are blocked from being switched to other user ports, isolating different user segments; in VLAN-based mode, this isolation applies selectively to specific VLANs. An operator would configure this to enforce network security policies or to isolate customer segments in multi-tenant environments.
