Switching 8-5 Introduction This chapter gives an overview of Layer 1 (the physical layer), 2 (the data link layer), and 3 (the network layer) switching, and describes the support for switching and how to configure and operate the switching functions. The switch, also referred to as a MAC (media access control) bridge, a data link relay, or a Layer 2 switch, can connect multiple Local Area Network (LAN) segments together to form an extended LAN.
8-6 Rapier Switch Software Reference ■ Further improve LAN performance, as broadcast traffic is limited to LAN segments serving members of the VLAN to which the sender belongs. ■ Provide security, as frames are forwarded to those stations belonging to the sender’s VLAN, and not to stations in other VLANs on the same physical LAN. ■ Reduce the cost of moving or adding stations to function or security based LANs, as this generally requires only a change in the VLAN configuration.
Switching 8-7 Autonegotiation of Port Speed and Duplex Mode Each of the switch ports can operate at either 10 Mbps or 100 Mbps, in either full duplex or half duplex mode. In full duplex mode, a port transmits and receives data simultaneously. In half duplex mode, the port either transmits or receives, but not at the same time. This versatility makes it possible to connect devices with different speeds and duplex modes to different ports on the switch.

Switching 8-9 All the ports in a trunk group must have the same VLAN configuration: they must belong to the same VLANs and have the same tagging status. All ports in a trunk group must be added to VLANs together, and can only be deleted from a VLAN as a group. Similarly, if the tagged or untagged status of the ports is changed, it must be changed for all ports in the trunk group at the same time.
8-10 Rapier Switch Software Reference ■ terminate on the same device ■ be members of the same VLANs ■ have the same data rate ■ share the same admin port key (assigned by using the command, add lacp port command on page 8-71). The hardware must also be capable and have the capacity to handle the number of links to be aggregated. Aggregated group identification In order to identify particular aggregated groups, each group is assigned a link aggregation identifier called a lag ID.
Switching 8-11 Port Mirroring Port mirroring allows traffic being received and transmitted on a switch port to be sent to another switch port, the mirror port, usually to capture data with a protocol analyser. The mirror port is the only switch port that belongs to no VLANs, and therefore does not participate in any other switching. Before the mirror port can be set, it must be removed from all VLANs except the default VLAN. The port cannot be part of a trunk group.
8-12 Rapier Switch Software Reference addresses on a locked port. To disable port security on a port, set the limit for learned MAC addresses to zero or none. Port security can be enabled or disabled on a port by using the command: set switch port={port-list|all} learn={none|0|1..
Switching 8-13 ■ Connect 802.1q-compatible switches together through one port on each switch Devices that are members of the same VLAN exchange data with each other through the switch’s switching capabilities. To exchange data between devices in separate VLANs, the switch’s routing capabilities are used. The switch passes VLAN status information, indicating whether a VLAN is up or down, to the Internet Protocol (IP) module. IP uses this information to determine route availability.
8-14 Rapier Switch Software Reference Single-host mode In single host mode, VLAN assignment is as follows: ■ If authentication fails, the supplicant is denied access to the port. The port is placed in its configured access VLAN, that is, the VLAN it was set up for in the add vlan command. ■ If the RADIUS server supplies valid VLAN information, the port is placed in the specified VLAN after configuration.
Switching 8-15 state. This effectively disables the guest VLAN on the port until the port’s link goes down. A guest VLAN can only be configured for a port that is running in singlesupplicant mode. VLAN Tagging An Ethernet packet can contain a VLAN tag with fields that specify VLAN membership and user priority. The VLAN tag is described in IEEE Standard 802.3ac, and is four octets that can be inserted between the Source Address and the Type/Length fields in the Ethernet packet (Figure 8-1 on page 8-16).
8-16 Rapier Switch Software Reference Figure 8-1: Format of user priority and VLAN data in an Ethernet frame Destination Address 64 bits 48 bits TPID 16 bits Source Type/ Address Length Frame Data 48 bits 16 bits User Priority CFI 3 bits 1 bit Preamble 368-12000 CRC 32 bits VID 12 bits 0x81-00 SWITCH6 Table 8-3: Reserved VID values VID value (hexadecimal) Meaning and use of reserved VID values 0 The null VLAN ID.
Switching 8-17 associated with the VID of the VLAN for which the incoming port is untagged. When the switch forwards a frame over a tagged port, it adds a VLAN tag to the frame. When the switch forwards the frame over an untagged port, it transmits the frame as a VLAN-untagged frame, not including the VID in the frame. The VLAN tag that the switch adds to a frame on egress depends on whether the frame is switched in Layer 2 or Layer 3.

Switching 8-19 If the network includes VLANs that do not need to share network resources or span several switches, VLAN membership can usefully be based on untagged ports. Otherwise, VLAN membership should be determined by tagging (see “VLAN Tagging” on page 8-15). Figure 8-3 on page 8-19 shows two port-based VLANs with untagged ports. Ports 1-3 belong to the marketing VLAN, and ports 14-16 belong to the training VLAN.
8-20 Rapier Switch Software Reference To add tagged ports to a VLAN, use the command: add vlan={vlan-name|1..4094} port={port-list|all} frame=tagged A port can be tagged for any number of VLANs. To add untagged ports to a VLAN, use the command: add vlan={vlan-name|1..4094} port={port-list|all} [frame=untagged] A port can be untagged for zero or one VLAN. A port can be added only to the default VLAN as an untagged port when it is not untagged for another VLAN.
Switching 8-21 Summary of VLAN Tagging Rules When designing a VLAN and adding ports to VLANs, consider the following rules: • Except for the mirror port, each port must belong to at least one static VLAN. By default, a port is an untagged member of the default VLAN. • A port can be untagged for zero or one VLAN. A port that is untagged for a VLAN transmits frames destined for that VLAN without a VLAN tag in the Ethernet frame. • A port can be tagged for zero or more VLANs.
8-22 Rapier Switch Software Reference Protected VLANs If a VLAN is protected, Layer 2 traffic between ports that are members of a protected VLAN is blocked. Traffic can be Layer 3 switched to another VLAN. This feature prevents members of a protected VLAN from communicating with each other yet still allows members to access another network. Layer 3 Routing between ports in a protected VLAN can be prevented by adding a Layer 3 filter.

8-24 Rapier Switch Software Reference Private VLANs on Rapier 48i Switches The ports on Rapier 48i switches are divided into two instances: • ports 1-24 plus uplink port 49 • ports 25-48 plus uplink port 50 Private VLANs on a Rapier 48i switch can consist of only ports from one instance. Both the private ports and the uplink port must be in the same instance. Configuring Private VLANs To create a private VLAN and add ports to it: 1.
Switching 8-25 VLAN Relaying VLAN relaying allows the passage of traffic between the VLANs on one switch, for protocols that are not processed by the switch’s routing functions. Particular protocols or protocol groups can be specified, and filtering occurs on the basis of protocol identification number. VLAN relaying is similar to the bridging function of an Allied Telesyn router. Protocol names have been predefined for many protocol types.
8-26 Rapier Switch Software Reference Table 8-5: Predefined protocol types implemented by VLAN relay (Continued) Protocol Name Protocol Number Encapsulation IBM SNA 80D5 EthII SNMP 814C EthII AllSNAP all SNAP protocols SNAP VLAN relaying operates in the following stages: 1. The user creates one or more VLAN relay entities and adds the required VLANs and protocols to each entity. 2. The VLAN relay entity attaches to each specified VLAN and receives traffic.
Switching 8-27 Protocols are specified by protocol type and number, or by allowing all protocols of a certain type. A predefined list of common protocols is provided in Table 8-5 on page 8-25. VLANs and/or protocols can be removed from an existing VLAN relay entity by using the command: delete vlanrelay=name [protocol=protocoltype] vlan=[{vlanname|1..
8-28 Rapier Switch Software Reference The Ingress Rules When a frame first arrives at a port, ingress rules for the port check the VLAN tagging in the frame to determine whether to discard it or forward it to the learning process. The first check depends on whether the Acceptable Frame Types parameter is set to Admit All Frames or to Admit Only VLAN Tagged Frames.
Switching 8-29 If the ageing timer for an entry in the forwarding database expires before another frame with the same source address is received, the entry is removed from the forwarding database. This prevents the forwarding database from being filled up with information about stations that are inactive or have been disconnected from the network, while ensuring that entries for active stations are kept alive in the forwarding database.
8-30 Rapier Switch Software Reference The forwarding process provides storage for queued frames to be transmitted over a particular port or ports. More than one transmission queue may be provided for a given port. The transmission queue where a frame is sent is determined by the user priority tag in the Ethernet frame and the Quality of Service mapping (see “Quality of Service” on page 8-30).
Switching 8-31 The Egress Rules After the forwarding process determines the ports and transmission queues from which a frame is forwarded, the Egress Rules for each port determine whether the outgoing frame is VLAN-tagged with its numerical VLAN Identifier (VID). When you add a port to a VLAN, configure it to transmit either untagged or VLAN tagged packets by using the command: add vlan={vlan-name|1..
8-32 Rapier Switch Software Reference the frame is transmitted on the port specified by the entry in the forwarding database. Spanning Tree Protocol (STP) The Spanning Tree Protocol (STP) automatically disables redundant paths in a network to avoid loops, and enables them when a fault in the network means they are needed to keep traffic flowing. A sequence of LANs and switches may be connected together in an arbitrary physical topology resulting in more than one path between any two switches.
Switching 8-33 Once the spanning tree is established, it is maintained by: 1. Replacing a failed path with a redundant backup path, if one is available. 2. Detecting and removing loops by declaring ports redundant and removing them from the logical spanning tree. 3. Maintaining timers that control the ageing of the forwarding database entries.
8-34 Rapier Switch Software Reference A spanning tree running in standard mode can take up to one minute to rebuild after a topology or configuration change. The Rapid Spanning Tree algorithm provides for a more rapid recovery of connectivity following the failure of a bridge, bridge port, or a LAN.
Switching 8-35 Table 8-7: Spanning Tree port states State Meaning DISABLED STP operations are disabled on the port. The port does not participate in frame relay or the operation of the Spanning Tree Algorithm and Protocol. The port can still switch if its switch state is enabled. BLOCKING The port does not participate in frame relay. The forwarding process discards received frames and does not submit forwarded frames for transmission. This is the “standby” mode.
8-36 Rapier Switch Software Reference If creating multiple STPs in a network, consider the following: • A VLAN can only belong to a single STP. • Except on the Rapier i Series switches, any port in the switch must belong only to a single STP. When a port is a member of multiple VLANs, all these VLANs must belong to the same STP. Within any given STP, all VLANs belonging to it use the same Spanning Tree.
Switching 8-37 By default, all VLANs, and therefore all ports, belong to the default STP. To add or delete a VLAN and all the ports belonging to it from any other STP, use the commands: add stp=stp-name vlan={vlan-name|2..4094} delete stp=stp-name vlan={vlan-name|2..4094|all} The default STP is disabled by default at switch start up, and STPs created by a user are disabled by default when they are created.
8-38 Rapier Switch Software Reference To modify the parameters controlling these time intervals, use the command: set stp={stp-name|all} [forwarddelay=4..30] [hellotime=1..10] [maxage=6..40] The value of the priority parameter is used to set the writable portion of the bridge ID, i.e. the first two octets of the (8-octet long) Bridge Identifier. The remaining 6 octets of the bridge ID are given by the MAC address of the switches.

Switching 8-41 Multiple Spanning Tree Protocol (MSTP) The multiple spanning tree protocol (MSTP) was developed to address the limitations in the existing spanning tree protocols, STP and RSTP. These limitations apply mainly to networks that use multiple VLANs with topologies employing alternative physical links. MSTP is defined in IEEE Standard 802.1Q 2003. The protocol builds on, and remains compatible with, the following previous standards: ■ IEEE Standard 802.
8-42 Rapier Switch Software Reference Table 8-12: MST Configuration identifier Field Name Description Format Selector A single octet field whose value of 0 indicates MSTP operation Configuration Name A name (up to 32 characters long) that identifies a particular MST region. The configuration name is defined using the SET MSTP command. Revision Level A number representing the region’s revision level. This value is normally set to 0.

CIST Port Identifier 26–27 CIST port identifier of the transmitting bridge port. Message Age 28–29 Message age timer value. Max Age 30–31 Timeout value to be used by all bridges in the bridged network. This value is set by the root. Some implementations of MSTP may choose not to use this value.
8-44 Rapier Switch Software Reference Table 8-14: MSTI configuration messages MSTI Port Priority 15 Bits 5 through 8 are used to convey the value of the port identifier priority for this MSTI. Bits 1 through 4 are transmitted as 0, and ignored on receipt. MSTI Remaining Hops 16 Value of remaining hops for this MSTI. Compatibility with Previous Spanning Tree Protocols MSTP provides for compatibility with older spanning tree protocols in several ways.
Switching 8-45 Configuring MSTP The configuration examples in this section are based on the network shown in Figure 8-6 on page 8-45. This simple network comprises three LAN bridges connected in a multi-linked mesh configuration. The network is configured as a single MSTP region, called a MSTR, and given the name, Head Office. Two spanning tree instances (MSTIs) are created within this region called MSTI 2 and MSTI 3.
8-46 Rapier Switch Software Reference Configure Switch 1 1. Name the system and set manager port. set system name=switch1 set manager asyn=0 2. Create VLAN 12 and assign it a VID of 12. create vlan=vlan12 vid=12 3. Create VLAN 25 and assign it a VID of 25. create vlan=vlan25 vid=25 4. Add VLAN 12 to the required ports, as tagged ports. add vlan=12 po=3,4,5,6,7,8 frame=tagged 5. Add VLAN 25 to the required ports, as tagged ports. add vlan=25 po=3,4,5,6 frame=tagged 6. Set MSTP on Switch 1.
Switching 8-47 Configure Switch 2 1. Name the system and set manager port. set system name=switch2 set manager asyn=0 2. Create VLAN 12 and assign it a VID of 12. create vlan=vlan12 vid=12 3. Create VLAN 25 and assign it a VID of 25. create vlan=vlan25 vid=25 4. Add VLAN 12 to the required ports, as tagged ports. add vlan=12 po=3,4,5,6,7,8,9,10 frame=tagged 5. Add VLAN 25 to the required ports, as tagged ports. add vlan=25 po=3,4,9,10 frame=tagged 6. Set MSTP on Switch2.
8-48 Rapier Switch Software Reference Configure Switch 3 1. Name the system and set manager port. set system name=switch3 set manager asyn=0 2. Create VLAN 12 and assign it a VID of 12. create vlan=vlan12 vid=12 3. Create VLAN 25 and assign it a VID of 25. create vlan=vlan25 vid=25 4. Add VLAN 12 to the required ports, as tagged ports. add vlan=12 po=5,6,9,10 frame=tagged 5. Add VLAN 25 to the required ports, as tagged ports. add vlan=25 po=5,6,9,10 frame=tagged 6. Set MSTP on Switch 3.
Switching 8-49 Root bridge selection for MSTP MSTIs The MSTP protocol will select its root bridges for each MSTI. It does this by selecting, for each MSTI, the bridge that contains (numerically) the lowest bridge identifier. This is shown in Figure 8-7 on page 8-49.
8-50 Rapier Switch Software Reference Path selection for MSTP MSTIs After the protocol has selected its root bridge for each MSTI, it selects which are to be the active and blocked paths for each MSTI. The port with the best path to the root bridge is selected as the foot port and becomes active. Other ports that also lead to the root bridge, but via a path that is better than the path back through the switch, are selected as alternate ports and are blocked to prevent loops.
Switching 8-51 other path is blocked. Similarly, the active path between Switches 2 and 3 is between Port 9 on each switch. For MSTI 2 Between Switches 1 and 3 there are two paths available, Port 5 to Port 5, and Port 6 to Port 6. Since no port priority has been explicitly applied, all port configurations have their defaults. Since all ports have the same speed (100 MBPS) each port has a Port Path Cost of 200,000.
8-52 Rapier Switch Software Reference Configuring the CIST Example Configuring this network involves the same basic steps used in the previous examples. Note that the only VLAN that is common to both regions is VLAN 12, which uses MSTI 3. These must be explicitly configured to Ports 1 and 10 of Switches 3 and 4. For Switch 3 1. Add VLAN 12 to the required ports, as tagged ports. add vlan=12 po=1,10 frame=tagged set mstp msti=2 port=10 pathcost=1000 For Switch 4 1.
Switching 8-53 CIST Vectors Having selected the CIST Root and Designated bridge, the CIST will then deal with any loops that exist between the regions. It will do this by considering the following entities, called “vectors” in the following order: 1. CIST External Root Path Cost 2. CIST Regional Root Identifier 3. CIST Internal Root Path Cost 4. CIST Designated Bridge Identifier 5. CIST Designated Port Identifier 6.

Switching 8-55 The Relationship between Spanning Trees and Trunks If multiple links are trunked together, either manually or by using an automatic process such as LACP, the spanning tree application is notified and considers the links as a single logical path. Consequently, the spanning tree broadcast messages (BPDUs) only traverse the master trunk path. Whether trunking offers a better solution depends on the individual network configuration.
