SAFETY INFORMATION
CLASS 1 LASER TRANSCEIVERS
THE FE-100F3 FAST ETHERNET INTERFACE MODULE, FPIM-05 AND
FPIM-07 FDDI PORT INTERFACE MODULES, AND APIM-29 ATM
PORT INTERFACE MODULE USE CLASS 1 LASER TRANSCEIVERS.
READ THE FOLLOWING SAFETY INFORMATION BEFORE
INSTALLING OR OPERATING THESE MODULES.
The Class 1 laser tran sce ivers use an optical feedbac k loop to maintain Class 1 operation limits. This control loop eliminates the need for maintenance checks or adjustments. The output is factory set, and does not allow any user adjust m en t. Class 1 La ser t ransceivers comply with th e fol lowing safety standards:
• 21 CFR 1040.10 and 1040.11 U.S. Department of Health and Human Services (FDA).
• IEC Publication 825 (International Electrotechnical Commission).
• CENELEC EN 608 25 (European Commit te e for Electrotechnical Standardizati on). When operating wi thin their performanc e l im it ations, laser transceiver output meets the Class 1
accessible emission l imit of all three standards. Clas s 1 lev el s of laser ra dia t ion are not considered hazardous.
SAFETY INFORMATION
CLASS 1 LASER TRANSCEIVERS
LASER RADIATION AND CONNECTORS
When the conne ctor is in place, all laser radiation remains within the fib er. The maximum amount of radiant power exit ing the fiber (under normal condi t ion s) is -12. 6 dBm or 55 x 10
Removing the optical connecto r from the transceiver al lows laser radiation to emit directly from the optical port. The maximum radiance from the optical port (unde r worst case conditions) is
0.8 W cm
Do not use optical instruments to view the laser output. The use of optical instruments to view laser output increases eye hazard. When viewing the output optical port, power must be removed from the network adapter.

CHAPTER 1
INTRODUCTION
1.1 PRODUCT OVERVIEW
The SmartSTACK Ethernet ELS10-27TX provides a low cost, high performance solution for 10/100 Mbps switched networks. The SmartSTACK Ethernet ELS10-27TX is configured wi th twenty-seven RJ 45 ports support ing twenty-four autonegotiati ng 1 0 Mbps por ts an d th ree autonego tiatin g 10/ 100 Mbp s por ts. Th e device also features two EPIM-100 slots that allow the user to install up to two EPIM-100s to provide multimode fiber uplinks (with potential for single mode fiber). It also includes an RS232C port for local console management.
In ELS10-27TX Version 1.0.1.00, the SmartSTACK Ethernet ELS10-27TX supports two forms of Virtual LANs. One is the IEEE 802.1Q standard and the other is a proprietary form that was developed prior to the IEEE standard being available. The pr oprietary for m is known as Workgroups. V irtual Workgroups are only supported i n the 802.1D mode and VLANs are only suppo rted in the 80 2.1Q mode. This manual documents both forms.
Also, modification of existing LCM commands were added that describe how to set an address limit on a port and how to configure destination IP addresses for
traps. For information on “enable address limit” and “trap control” refer to Chapter 2, Enhancements to LCM Commands.
This document does not attempt to d escribe the entire functionality of the SmartSTACK Ethernet ELS10-27TX product, but only differences between Version 1.00.xx and Version 1.01.00 of the SmartSTACK Ethernet ELS10-27TX product.
1.2 USING VLANS ON THE ELS10-27TX
This section describes Virtual Local Area Networks (VLANs) support for the SmartSTACK Ethernet ELS10-27TX switch. This section describes support for the IEEE 802.1Q standard.
1-1
Introduction
1.2.1 IEEE 802.1Q Standard
IEEE 802.1Q is a standard for virtual bridged local area networks (VLANs). It provides an alternate method for forwarding packets through a switch. In an
802.1D (Spanning Tree) bridge, packets are forwarded in accordance with the
spanning tree as dynamically created by the 802.1D protocol (Bridge Protocol Data Units [BPDUs]), and the spanning tree state of each port. In 802.1Q, in addition to spanning tree, packets are forwarded in accordance with a VLAN tag that is embedded in the packet, and the set of ports registered for that VLAN. A set of rules is used for ingress (receipt), forwarding, and egress (transmit).
The SmartSTACK Ethernet ELS10-27TX provides support for port based VLANs.
The ingress rules deal with the reception of tagged and untagged packets and the decision to either drop them, or forward them to the forwarding process.
The forwarding rules deal with forwarding packets using topology restrictions, the filtering database, queue frames (not supported), map priorities (not supported), and recalculation of the FCS. The forward/filtering database can contain three types of entries:
Permanent entries
Static entries
Dynamic entries
Dynamic entries are created using the protocols supported by the switch (GVRP). There will be no learning of VLANs outside of this protocol.
NOTE
There is no support for GVRP with ELS10-27TX Version 1.01.00.
GVRP will be supported in a subsequent release.
The egress rules deal with whether the destination port(s) are members of the VLAN, and whether the VLAN tag is to be stripped. There is also an issue of address translation on a packet that is having the VLAN tag stripped. This only applies to multi-protocol environ ments, such as a combination of Ethernet, FDDI, and Token Ring protocols and does not apply to the SmartSTACK Ethernet ELS10-27TX.
The 802.1Q standard does not replace 802.1D. It limits the relaying of packets on the spanning tree to a subset: the subset being the members of a particular VLAN. This is determined by comparing th e VLAN ID, which is a field with in the tag, to the ports which are members of that VLAN.
1-2
Introduction
Tag-aware devices should not exist on a segment
The 802.1Q VLANs spans multiple systems and could span the entire network. Unlike Workgroups, VLANs are not limited within a particular unit. The maximum number of VLANs supported in 802.1Q mode on ELS10-27TX is 32.
1.3 802.1Q MODE ON ELS10-27TX
The SmartSTACK Ethernet ELS10-27TX operates in two modes: 802.1D and
802.1Q. While operating in 802.1Q mode, ports can be configured to allow non-
802.1Q devices to operate in this environment.
1.3.1 VLAN Hybrid Ports (802.1Q Mode)
A VLAN Hybrid port is used to connect one or more VLAN-aware or VLAN­unaware devices to the switch. Both tagged and untagged frames can be received and transmitted on Hybrid ports.
If a port on the ELS10-27TX is not configured as an Access port, it is a Hybrid port.
1.3.2 VLAN Access Ports (802.1Q Mode)
The VLAN feature must be used only when non-802.1Q devices are attached to this port. These ports are known as access ports.
An access command is a sub-command of the port command. An access port is used to allow each segment to have multiple tag-unaware devices on it, and to have those devices communicating on multiple VLANs.
An access port has three major characteristics:
1. When a packet is received, it will always insert a tag into the packet.
NOTE
2. When a port transmits a packet, it always strips off the tag, even if it does not match the default VLAN ID for that port.
3. Additional entries must be placed into the database to support it. When addresses are learned on access ports, add itional MAC addresses/VLAN ID pairs are placed into the database to avoid flooding and to establish connectivity.
connected to an access port.
For further information on Access Ports, refer to Appendix A, Virtual LANs (VLANs).

Introduction
1.3.3 802.1Q Trunk Ports
An 802.1Q trunk port passes all packets with the tag in place. It will not strip the tag. The port must be a hybrid port. There is no explicit command to create
802.1Q trunks ports. The following are two ways of implementing trunk ports:
Preserving Priority. The default port VLAN ID (PVID) must be identical at both ends of the tru nk link. The PVID us ed must be a value not us ed anywhere else in the network to pass traffic. Because this VLAN ID is unique, it will not be stripped from the packet on egress and therefore will pass the priority bits intact.
Non-Preserving Priority . The default port VLAN ID (PVID) must be identical at both ends of the trunk link . The VLAN ID will be stripped on egress and re­inserted on ingress. However, the priority bits will be lost.
NOTE
All VLAN ports by default are hybrid ports.
1.3.3.1 Preserving Priority
The 802.1Q trunk passes all packets with the tag in place. It will not strip the tag. All packets traversing the link will contain a tag. The administrator should set a policy that certain VLAN IDs must be reserved and must not be used for traffic.
For example, when reserv ing VLAN IDs 0xf f0 throug h 0xff e, one of th ese can be used as the PVID for both ends of trunk links. By doing this, the priority bits can be passed intact. Both ends of the link should be defined as Hybrid so that they only strip tags if they match the PVID. Because the tag in the packet traversing the trunk will never match the PVID, it will not be stripped. Also, because the packet is always received with a tag, the PVID is never inserted.
Preserving priority works best when the end device inserts the tag and supports priority (priority is not used by the ELS10-27TX, but is passed within the packet). Therefore, the trunk will not strip a tag or insert a tag, thus the priority fields are passed intact.
1-4
Introduction
1.3.3.2 Non-Preserving Priority
Use this method if there is no concern about passin g priority from one device to another. Configure the same P VID at bo th ends of th e trunk l ink to en sure t hat all traffic will be forwarded correctly.
In order to implement this, the ports at both ends of the link must work the same, that is:
Strips tags on egress of the ports that match the PVID
Inserts a tag using the PVID when there is no tag
Changes the tag on egress with an ID of zero to the PVID
The tag will be stripped on egress of that port, when it matches the PVID. When the packet is received by the peer, a tag with the same VLAN ID will be inserted and the packet will be forwarded as though the packet traversed the trunk link with the tag in place. However, the priority bits will not be reserved.
1.3.4 Accessing Network Management Using VLANs
When an IP address is configured on the unit, it must be associated with the VLAN. If multiple VLANs are configured on a switch, you can configure multiple IP addresses provided they are on separate subnets. Therefore, when an IP address is assigned to a switch, the VLAN ID for the subnet must be specified. When the network management processor issues a response to a network management packet, it selects the correct VLAN ID to use based on the IP subnet.
For further infor mation, refer to IP A ddress Command or the VLAN Command in Chapter 2, Enhancements to LCM Commands.

Introduction
1.3.5 Switch Mode
The unit operates in either an 802.1D or 802.1Q mode. The mode must be selected by the user and applies to all ports. The unit will not operate in a mixed mode. The default is to operate in 802.1D mode.
For further information, refer to Switch Command in Chapter 2, En hancements to
LCM Commands.
1.3.6 Assigning Ports to a VLAN
A port becomes a member of a VLAN, by using the VLAN command. For further information, refer to the Port Command in C hap t er 2, En han cement s
to LCM Comman d s .
1.3.7 Default Port VLAN ID
If the unit is operating in 802.1Q mode, then each port will be configured with a default port VLAN ID (PVID). The default v alue for each p ort will be th e default VLAN ID of 0x001. You are allowed to modify this on a per port basis.
When 802.1Q was developed, it was deci ded to configure a defaul t VLAN ID for a port. If a packet is received on a port that does not have a VLAN ID or does not have a VLAN ID of zero, the default VLAN ID will be inserted. Once this tag is in place the packet is sent to the forwarding engine. Once the forwarding engine receives it, it will use this tag to determine which VLAN to restrict this packet to.
The sub-command of the port command known as the VLAN sub-command is used to set the default VLAN ID for the port.
NOTE
For further information, refer to Port Command in Chapter 2, Enhancements to LCM Commands.
There is a sub-command of the port command known as the VLAN sub-command. This is not used to make a port a member of the VLAN, and is not directly used in the forwarding and
filtering decision.
1-6
Introduction
1.3.8 Restrict ing VLANs (802.1Q Mode)
This command will allow you to specify a list of VLAN IDs that should not be dynamically learned by GVRP. When the management processor receives a GVRP packet, it checks this database to det ermin e if the learning of this ID should be restricted.
NOTE
There is no support for GVRP with ELS10-27TX Version 1.01.00. GVRP will be supported in a subsequent release.
For usage, refer to the VLAN Command in Chapter 2, Enhancements to LCM Commands.
1.3.9 Enable GVRP
GVRP can be enabled on a per port basis using the Port command.
NOTE
For further information, refer to the Port Command in C hap t er 2, En hancements to LCM Comman d s .
There is no support for GVRP with ELS10-27TX Version 1.01.00. GVRP will be supported in a subsequent release.

Introduction
1.4 WORKGROUPS
This section describes Workgroup support for the SmartSTACK Ethernet ELS10-27TX switch. The switch supports up to eight user defined Workgroups, with limited support for overlapping Workgroups.
The purpose of Workgroups is to isolate broadcast and multicast traffic to within the W orkgroup. In some cases, unicast traffic will also be isolated. Due to the fact that a typical unicast address is obtained by first issuing an ARP packet (which is a broadcast, and the broadcast packet will not be forwarded outside of the Workgroup), the unicast address will not be learned outside of the Workgroup. The end result is that host or servers will not be able to communicate with other hosts or servers outside of their Workgroup.
Unlike IEEE standard VLANs which span switches, Workgroups only deal with filtering and forwarding of frames within the single switch. When packets are received on a port, the packet will be identified with a single Workgroup. The packet will then be forwarded or filtered based on that single Workgroup marking. When a packet leaves the switch, the packet will appear just as it did when it was received on the inbound port.
The SmartSTACK Ethernet ELS10-27TX allows you to define ports for logical groups of associated devices (virtual workgroups) to provide a more efficient flow of traffic acros s your Ether net netw ork. You can define a maximum of eight virtual workgroups. The number of ports within a Workgroup is not restricted and an individual port can be a member of multiple Virtual Workgroups.
NOTE
Virtual Workgroups will only operate in 802.1D mode.
V irtual workgroups offer the ability to limit broadcasts to logical domains within the network. Workgroup destinations are recognized by the SmartSTACK Ethernet ELS10-27TX and broadcast and unicast packets are routed directly to hosts within the workgroup, eliminating the need to perform a general broadcast across each segment of the network to find specific host addresses.
For further information, refer to the Wo rkgroup Command in Chapter 5,
Configuring Workgroups Using LCM.

Introduction
1.5 DEFAULT GATEWAY
A default gateway field was added to the router command to allow communication to a device on a subnet not configured on this switch.
For information on configuring the Default Gateway, refer to Chapter 2,
