200-301 ccna dump.For structure, this section is divided into five main points. The first is a review of the LAN switching forwarding process and an introduction to the 4 main steps of LAN switching troubleshooting. This is followed by a detailed analysis of each step in turn.1. Overview of the Common LAN Switch Forwarding Process Chapter 1 of this book outlined the logic of using a LAN switch to forward frames when forwarding frames. However, the logic described in that list does not includeThe following step-by-step procedure outlines that logic and notes the impact of STP on the switch forwarding process. Step 1 Determine the VLAN to which the frame is forwarded, as follows.a.If the frame arrives at the accessor interface, use the access VLAN of the interface.Step 2 If the input interface in this VLAN is in the STP learning or forwarding state, add the source MAC address to the MAC address table.including the input interface and VLAN ID (if not already in the table). Step 3 If the input interface in this VLAN is not in the STP forwarding state, discard the frame. Step 4 Look in the MAC address table for the destination MAC address of the frame, but only for the VLAN table entry identified in Step 1. Regardless of whether thedestination MAC address is found or not, the following steps are performed. a.Found: Forward the frame through the matching address table entry from the unique interface listed there.b.Not found: flood this frame to all other access ports in the same VLAN that are in the STP forwarding state, and to all trunk ports that are fully supported by this VLAN (active, in the allowed list, unpruned, STP forwarding) outside of the VLAN. To forward a frame, the switch must first determine in which VLAN the frame is to be forwarded (step 1), which requires learning the source MAC address (step2), and then choose where to forward the frame. To ensure a clear demonstration of this process, Figure 3-3 shows an example where PC1 sends a frame to its default gateway, R1, with the corresponding MAC address indicated in the figure.3.2 Basic Content 55
