The switch includes a first port associated with a first VLAN and a second port associated with a second VLAN. The switch detects a PTP frame at the first port and the PTP module receives the PTP frame. The switch forwards the PTP frame to the second port in response to the PTP module determining that the PTP frame is a forwardable frame. For another embodiment, the switch includes a ternary content-addressable memory (“TCAM”), and the PTP module configures the TCAM to include forwarding rules. The Layer 2 switch forwards the PTP frame to the second port in response to identifying a particular forwarding rule associated with forwarding the PTP frame."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"PTP transparent clock with inter-VLAN forwarding","description":"There is described a Precision Time Protocol (“PTP”) transparent clock for inter-VLAN forwarding comprising a Layer 2 switch and a PTP module.
