Page 26: Switch Management And Operating Concepts
Switch (see Chapter 6, “Using the Console Interface”). A network administrator can manage, control and monitor the switch from the console program. The DES-3226 contains a CPU, memory for data storage, flash memory for configuration data, operational programs, and SNMP agent firmware. These components allow the Switch to be actively managed and monitored from either the console port or the network itself (out-of-band, or in-band).
Page 27: Ip Addresses And Snmp Community Names
100. If you still don’t see anything, try hitting <Ctrl> + r to refresh the screen. IP Addresses and SNMP Community Names Each Switch must be assigned its own IP Address, which is used for communication with an SNMP network manager or other TCP/IP application (for example BOOTP, TFTP). The Switch’s default IP address is 10.90.90.90.
Page 28: Traps
For security, you can set in the Switch a list of IP Addresses of the network managers that allow you to manage the Switch. You can also change the default SNMP Community Strings in the Switch and set the access rights of these Community Strings.
Page 29: Mibs
• Modifying the configuration of network devices. The DES-3226 has a software program called an ‘agent’ that processes SNMP requests, but the user program that makes the requests and collects the responses runs on a management station (a designated computer on the network). The SNMP agent and the user program both use the UDP/IP protocol to exchange packets.
Page 30: Packet Forwarding
If the Aging Time is too short however, many entries may be aged out too soon. This will result in a high percentage of received packets whose source addresses cannot be found in the forwarding table, in which case the switch will broadcast the packet to all ports, negating many of the benefits of having a switch.
Page 31: Spanning Tree Protocol
The DES-3226 STP allows two levels of spanning trees to be configured. The first level constructs a spanning tree on the links between switches. This is referred to as the Switch or Global level. The second level is on a port basis.
Page 32: Bridge Protocol Data Units
STP communicates between switches on the network using Bridge Protocol Data Units (BPDUs). Each BPDU contains the following information: • The unique identifier of the switch that the transmitting switch currently believes is the root switch • The path cost to the root from the transmitting port DES-3226 NWay Standalone Fast Ethernet Switch User’s Guide...
Page 33: Creating A Stable Stp Topology
A designated switch is selected. This is the switch closest to the root switch through which packets will be forwarded to the root. • A port for each switch is selected. This is the port providing the best path from the switch to the root switch. •...
Page 34 • From disabled to blocking When you enable STP, every port on every switch in the network goes through the blocking state and then transitions through the states of listening and learning at power up. If properly configured, each port stabilizes to the forwarding or blocking state.
Page 35: User-Changeable Stp Parameters
The user changeable parameters in the Switch are as follows: • Priority – A Priority for the switch can be set from 0 to 65535. 0 is equal to the highest Priority. •...
Page 36 DES-3226 NWay Standalone Fast Ethernet Switch User’s Guide Setting-up STP using values other than the defaults can be complex. Therefore, you are advised to keep the default factory settings and STP will automatically assign root bridges/ports and block loop connections.
Page 37: Vlans
Note also that the example network topology is intended to provide redundancy to protect the network against a link or port failure – not a switch failure or removal. For example, a failure of switch A would isolate LAN 1 from connecting to LAN 2 or LAN 3.
Page 38: 802.1Q Vlan Packet Forwarding
IEEE 802.1Q (tagged) VLANs are implemented on the DES-3226. 802.1Q VLANs require tagging, which enables them to span the entire network (assuming all switches on the network are IEEE 802.1Q- compliant).
Page 39: 802.1Q Vlan Tags
DES-3226 NWay Standalone Fast Ethernet Switch User’s Guide Figure 5-6. IEEE 802.1Q Packet Forwarding 802.1Q VLAN Tags The figure below shows the 802.1Q VLAN tag. There are four additional octets inserted after the source MAC address. Their presence is indicated by a value of 0x8100 in the EtherType field. When a packet’s EtherType field is equal to 0x8100, the packet carries the IEEE 802.1Q/802.1p tag.
Page 40: Port Vlan Id
DES-3226 NWay Standalone Fast Ethernet Switch User’s Guide Figure 5-7. IEEE 802.1Q Tag The EtherType and VLAN ID are inserted after the MAC source address, but before the original EtherType/Length or Logical Link Control. Because the packet is now a bit longer than it was originally, the Cyclic Redundancy Check (CRC) must be recalculated.
Page 41: Tagging And Untagging
Tag-aware switches must keep a table to relate PVIDs within the switch to VIDs on the network. The switch will compare the VID of a packet to be transmitted to the VID of the port that is to transmit the packet.
Page 42: Vlans
If the packet is not tagged with VLAN information, the ingress port will tag the packet with its own PVID as a VID (if the port is a tagging port). The switch then determines if the destination port is a member of the same VLAN (has the same VID) as the ingress port.

VLAN Example – Assigned Network Addresses Note: IP interfaces consist of two parts – a subnet mask and a network address. Note: Each IP interface listed above will give a maximum of 2,080,800 unique IP addresses per interface (assuming the 10.xxx.xxx.xxx notation).

Page 47: Configuring The Switch Using The Console Interface
Notes are added where clarification is necessary. Before You Start The DES-3226 supports a wide array of functions and gives great flexibility and increased network performance by eliminating the routing bottleneck between the WAN or Internet and the Intranet. Its function in a network can be thought of as a new generation of router that performs routing functions in hardware, rather than software.
Page 48: Console Usage Conventions
Note: The passwords used to access the Switch are case-sensitive; therefore, “S” is not the same as “s.” When you first connect to the Switch, you will be presented with the first login screen (shown below). Note: Press Ctrl+R to refresh the screen. This command can be used at any time to force the console program in the Switch to refresh the console screen.

Loading the Factory Default Configuration will erase any User Accounts (and all other configuration settings) you may have entered and return the Switch to the state it was in when it was purchased. The Load Factory Default Configuration Except IP Address option is used when the Switch will be managed by the Telnet manager, which requires knowledge of the Switch’s IP address to function.
Page 54: Viewing Current User Accounts
7. You must enter the configuration changes into the non-volatile ram (NV-RAM) using Save Changes from the main menu if you want the configuration to be used after a switch reboot. Only a user with Root privileges can make changes to user accounts.

Select the port you want to configure by using the drop-down menus in the From and To fields or click on the port in the Switch front panel display at the top of the window. Follow these steps: 1. Enable or disable the port. If you choose Disabled in the State field, devices connected to that port cannot use the Switch, and the Switch purges their addresses from its address table after the MAC address aging time elapses.
Page 106: Port Mirroring
3. Click Apply to let your changes take effect. Port Mirroring The Switch allows you to copy frames transmitted and received on a port and redirect the copies to another port. You can attach a monitoring device to the mirrored port, such as a sniffer or an RMON probe, to view details about the packets passing through the first port.
Page 107: Port Lacp Trunking
– to the backbone of a network. The Switch allows the creation of up to 6 port trunking groups, each group consisting of up to 8 links (ports). The trunked ports can be non-continuous (that is, have non-sequential port numbers). All of the ports in the group must be members of the same VLAN.
Page 108: Igmp Snooping
If two redundant port trunking groups are configured on the Switch, STP will block one entire group – in the same way STP will block a single port that has a redundant link.

BPDUs with other switches. This will determine which switch in the network is the best choice for the root switch. If there is only one switch on the network, no BPDU exchange occurs, the forward delay timer expires, and the ports move to the listening state. All STP enabled ports enter the blocking state following switch boot.
Page 164: Listening State
The listening state is the first transition for a port from the blocking state. Listening is an opportunity for the switch to receive BPDUs that may tell the switch that the port should not continue to transition to the forwarding state, but should return to the blocking state (that is, a different port is a better choice).

Page 168: Troubleshooting Stp
DES-3226 NWay Standalone Fast Ethernet Switch User’s Guide Troubleshooting STP Spanning Tree Protocol Failure A failure in the STA generally leads to a bridging loop. A bridging loop in an STP environment comes from a port that should be in the blocking state, but is forwarding packets.
Page 169: Unidirectional Link
DES-3226 NWay Standalone Fast Ethernet Switch User’s Guide In the above example, port 1 on B is configured as a full-duplex port and port 1 on A is either configured as a half-duplex port, or left in auto-negotiation mode. Because port 1 on B is configured as a full-duplex port, it does not do the carrier sense when accessing the link.
Page 170: Packet Corruption
Resource Errors The DES-3226 performs its switching and routing functions primarily in hardware, using specialized ASICs. STP is implemented in software and is thus reliant upon the speed of the CPU and other factors to converge. If the CPU is over-utilized, it is possible that BPDUs may not be sent in a timely fashion.
Page 171 Although the STP can elect a root bridge, a well-designed network will have an identifiable root for each VLAN. Careful setup of the STP parameters will lead to the selection of this best switch as the root for each VLAN. Redundant links can then be built into the network. STP is well suited to maintaining connectivity in the event of a device failure or removal, but is poorly suited to designing networks.
Page 172 DES-3226 NWay Standalone Fast Ethernet Switch User’s Guide In this example, the VLAN definitions are extended to switches A and B. This gives only a single blocked port per VLAN and allows the removal of all redundant links by removing switch A or B from the network.
