Stackable NWay Ethernet Switch User’s Guide 4 4 C ONNECTING T HE S WITCH This chapter describes how to connect the Switch to your Ethernet network. Switch to End Node End nodes include PCs outfitted with a 10, 100 or 10/100 Mbps RJ-45 Ethernet/Fast Ethernet Network Interface Card (NIC) and most routers. The RJ-45 UTP ports on NICs and most routers are MDI-II. When using a normal straight-through cable, an MDI-II port must connect to an MDI-X port.
Stackable NWay Ethernet Switch User’s Guide ♦ A 10BASE-T hub or switch can be connected to the Switch via a two-pair Category 3, 4 or 5 UTP/STP straight cable. ♦ A 100BASE-TX hub or switch can be connected to the Switch via a four-pair Category 5 UTP/STP straight cable.
Stackable NWay Ethernet Switch User’s Guide 5 5 S WITCH MANAGEMENT C ONCEPTS This chapter discusses many of the features used to manage the switch, and explains many concepts and important points regarding these features. Configuring the Switch to implement these concepts is discussed in detail in the next chapters. Local Console Management Local console management involves the administration of the Switch via a direct connection to the RS-232 DCE console port.
Stackable NWay Ethernet Switch User’s Guide IP Addresses and SNMP Community Names Each Switch has its own IP Address, which is used for communication with an SNMP network manager or other TCP/IP application (for example BOOTP, TFTP). You can change the default Switch IP Address to meet the specification of your networking address scheme. In addition, you can also set an IP Address for a gateway router.
Stackable NWay Ethernet Switch User’s Guide Topology Change Timer the new root trap is sent out immediately after the Switch’s selection as a new root. ♦ Topology Change A Topology Change trap is sent by the Switch when any of its configured ports transitions from the Learning state to the Forwarding state, or from the Forwarding state to the Blocking state. The trap is not sent if a new root trap is sent for the same transition.
Stackable NWay Ethernet Switch User’s Guide The Aging Time can be from 10 seconds to 9999 seconds. A very long Aging Time can result with the out-ofdate Dynamic Entries that may cause incorrect packet filtering/forwarding decisions.
Stackable NWay Ethernet Switch User’s Guide STA Operation Levels STA operates on two levels: the bridge level and the port level. On the bridge level, STA calculates the Bridge Identifier for each Switch, then sets the Root Bridge and the Designated Bridges. On the port level, STA sets the Root Port and Designated Ports. Details are as follows: On the Bridge Level ♦ Root Bridge The switch with the lowest Bridge Identifier is the Root Bridge.
Stackable NWay Ethernet Switch User’s Guide Root Bridge. If you set a Hello Time for your Switch, and it is not the Root Bridge, the set Hello Time will be used if and when your Switch becomes the Root Bridge. Note: The Hello Time cannot be longer than the Max. Age. Otherwise, a configuration error will occur. ♦ Bridge Max. Age The Max. Age can be from 6 to 40 seconds. At the end of the Max.
Stackable NWay Ethernet Switch User’s Guide Figure 5-2. After Applying the STA Rules STA parameters Settings Effects Comment Bridge Priority lower the #, higher the priority Increases chance of becoming the Root Bridge Avoid, if the switch is used in workgroup level of a large network Hello Time 1 - 10 sec. No effect, if not Root Bridge Never set greater than Max. Age Time Max. Age Time 6 - 40 sec.
Stackable NWay Ethernet Switch User’s Guide Figure 5-3. Port trunking example The switch treats all ports in a trunk group as a single port. As such, trunk ports will not be blocked by Spanning Tree (unless a redundant link with higher STP priority is present). Data transmitted to a specific host (destination address) will always be transmitted over the same port in a trunk group. This allows packets in a data stream to arrive in the same order they were sent.
Stackable NWay Ethernet Switch User’s Guide IEEE 802.1Q VLANs The Switch supports up to 96 IEEE 802.1Q (port-based) VLANs. Port-based VLANs limit traffic that flows into and out of switch ports. Thus, all devices connected to a port are members of the VLAN(s) the port belongs to, whether there is a single computer directly connected to a switch, or an entire department. On port-based VLANs, NICs do not need to be able to identify 802.1Q tags in packet headers. NICs send and receive normal Ethernet packets.
Stackable NWay Ethernet Switch User’s Guide Port PVID VID Ports Port 1 Port 2 Port 3 1 1 1 1 1,2,3,7 Port 7 3 3 1,2,3,7,11,1 2 Port 11 Port 12 2 2 2 11,12,7 Table 5-2. Example of possible VLAN assignments The server attached to Port 7 is shared by VLAN 1 and VLAN 2 because Port 7 is a member of both VLANs (it is listed as a member of VID 1 and 2). Since it can receive packets from both VLANs, all ports can successfully send packets to it to be printed.
Stackable NWay Ethernet Switch User’s Guide VLANs Over 802.1Q-compliant Switches When switches maintaining the same VLANs are 802.1Q-compliant, it is possible to use tagging. Tagging puts 802.1Q VLAN information into each packet header, enabling other 802.1Q-compliant switches that receive the packet to know how to treat it. Upon receiving a tagged packet, an 802.1Q-compliant switch can use the information in the packet header to maintain the integrity of VLANs, carry out priority forwarding, etc.
Stackable NWay Ethernet Switch User’s Guide Broadcast Storms Broadcast storms are a common problem on today’s networks. Basically, they consist of broadcast packets that flood and/or are looped on a network causing noticeable performance degradation and in extreme cases, network failure. Some of the causes of broadcast storms are network loops, malfunctioning NICs, bad cable connections, and applications or protocols that generate broadcast traffic.
Stackable NWay Ethernet Switch User’s Guide 6 6 U SING THE C ONSOLE I NTERFACE Your Stackable NWay Ethernet Switch supports a console management interface that allows you to set up and control your Switch, either with an ordinary terminal (or terminal emulator), or over the network using the TCP/IP Telnet protocol. You can use this facility to perform many basic network management functions.
Stackable NWay Ethernet Switch User’s Guide Figure 6-1. Example of a console connection Connecting to the Switch Using Telnet Once you have set an IP address for your Switch, you can use a Telnet program (in a VT-100 compatible terminal mode) to access and control the Switch. Most of the screens are identical, whether accessed from the console port or from a Telnet interface. You can also use a Web-based browser to manage the Switch.
