Note Statistics are automatically refreshed every 60 seconds 3 56 CHAPTER 4 ADVANCED TOPICS This TigerSwitch 10 100 supports Layer 2 switching and other advanced features which are described in this chapter Layer 2 Switching When a frame enters a port its destination MAC address is checked in the address database to see which port leads to this destination If the destination address belongs to the incoming port the frame is dropped or filtered because it addressed to the local segment If the destination address if found on another port the frame is forwarded to that port and queued for output But if the destination address is not found in the address database the frame is sent to one or more output ports based on the rules for handling tagged or untagged VLAN frames If the source MAC address of the frame was not found in the address database it is recorded along with the incoming port number where it entered the switch This information is then used to make later decisions for frame forwarding Switching involves the following steps VLAN Classification Learning Filtering Forwarding Aging 999 4 1 ADVANCED TOPICS Spanning Tree Algorithm 4 2 The Spanning Tree Algorithm that is the STA configuration algorithm as outlined in IEEE 802 1D can be used to detect and disable network loops and to provide link backup This allows the switch to interact with other bridging devices including

7. Troubleshooting Chart Symptom Action Cannot connect using Telnet Web browser or SNMP software Be sure to have configured the agent with a valid IP address subnet mask and default gateway Check that you have a valid network connection to the switch and that the port you are using has not been disabled Check network cabling between the management station and the switch If you cannot connect using Telnet you may have exceeded the maximum number of concurrent Telnet sessions permitted Try connecting again at a later time Can t access the on board configuration program via a serial port connection Be sure to have set the terminal emulator program to VT100 compatible 8 data bits 1 stop bit no parity and 19200 bps If the switch is configured for Auto baud rate detection the terminal emulator program must be set at 2400 19200 baud 8 data bits 1 stop bit no parity and flow control set to none Also you must first press the Enter key once to set the data rate and initialize the connection Check that the null modem serial cable conforms to the pin out connections provided in Appendix B Forgot or lost the password Contact SMC Technical Support for help TROUBLESHOOTING Upgrading Firmware via the Serial Port You can upgrade system firmware by connecting your computer to the serial port on the switch and using a console interface package that supports the XModem pro

STA compliant switches bridges or routers in your network to ensure that only one route exists between any two stations on the network If redundant paths or loops are detected one or more ports are put into a blocking state stopped from forwarding packets to eliminate the extra paths Moreover if one or more of the paths in a stable spanning tree topology fail this algorithm will automatically change ports from blocking state to forwarding state to reestablish contact with all network stations The STA uses a distributed algorithm to select a bridging device STA compliant switch bridge or router that serves as the root of the spanning tree network It selects a root port on each bridging device except for the root device which incurs the lowest path cost when forwarding a packet from that device to the root device Then it selects a designated bridging device from each LAN which incurs the lowest path cost when forwarding a packet from that LAN to the root device All ports connected to designated bridging devices are assigned as designated ports After determining the lowest cost spanning tree it enables all root ports and designated ports and disables all other ports Network packets are therefore only forwarded between root ports and designated ports eliminating any possible network loops Once a stable network topology has been established all bridges listen for Hello BPDUs Bridge Protocol Data Units transmitted from the Root
