31. © 2005, BDCOM –Address learning –Forward/filter decision –Loop avoidance Ethernet Switches and Bridges

32. © 2005, BDCOM Cut-Through Switch checks destination address and immediately begins forwarding frame. Fragment-Free Switch checks the first 64 bytes, then immediately begins forwarding frame. Store and Forward Complete frame is received and checked before forwarding. Transmitting Frames

33. © 2005, BDCOM MAC Address Table Initial MAC address table is empty.

34. © 2005, BDCOM Learning Addresses Station A sends a frame to station C. Switch caches the MAC address of station A to port E0 by learning the source address of data frames. The frame from station A to station C is flooded out to all ports except port E0 (unknown unicasts are flooded).

35. © 2005, BDCOM Learning Addresses (Cont.) Station D sends a frame to station C. Switch caches the MAC address of station D to port E3 by learning the source address of data frames. The frame from station D to station C is flooded out to all ports except port E3 (unknown unicasts are flooded).

36. © 2005, BDCOM Filtering Frames Station A sends a frame to station C. Destination is known; frame is not flooded.

37. © 2005, BDCOM Filtering Frames (Cont.) Station A sends a frame to station B. The switch has the address for station B in the MAC address table.

38. © 2005, BDCOM Station D sends a broadcast or multicast frame. Broadcast and multicast frames are flooded to all ports other than the originating port. Broadcast and Multicast Frames

43. © 2005, BDCOM Host X sends a unicast frame to router Y. MAC address of router Y has not been learned by either switch yet. Router Y will receive two copies of the same frame. Multiple Frame Copies

44. © 2005, BDCOM Host X sends a unicast frame to router Y. MAC address of router Y has not been learned by either switch. Switches A and B learn the MAC address of host X on port 0. The frame to router Y is flooded. Switches A and B incorrectly learn the MAC address of Router Y on port 1. MAC Database Instability

107. © 2005, BDCOM Problem: One Device Cannot Communicate with Another –Make sure the IP address, subnet mask, and VLAN membership of the switch interface is correct. –If the host is in the same subnet as the switch interface, make sure the switch interface and the switch port to which the host is connected are assigned to the same VLAN. –If the host is in a different subnet, make sure the default gateway on the switch is configured with the address of a router in the same subnet as the switch interface.

108. © 2005, BDCOM Problem: One Device Cannot Communicate with Another (Cont.) –If the port is in listening or learning mode, wait until the port is in forwarding mode and try to connect to the host again. –Make sure the speed and duplex settings on the host and the appropriate switch ports are correct. –If the connected device is an end station, enable spanning-tree PortFast, disable trunking, and disable chaneling on the port. –Make sure the switch is learning the MAC address of the host.

109. © 2005, BDCOM Problem: A Device Cannot Establish a Connection Across a Trunk Link –Make sure the trunking mode configured on both ends of the link is valid. The trunking mode should be on or desirable on one end and on, desirable, or auto on the other end. –Make sure the trunk encapsulation type configured on both ends of the link is valid. –On IEEE 802.1Q trunks, make sure the native VLAN is the same on both ends of the trunk.
