Place your switch close to the PC that you will use to configure it.
It helps if you can see the front panel of the switch while you work
on your PC.
Connect the Ethernet port of your PC to any port on the front panel
of your switch.
Insert the power adapter into the DC power socket in front of the
switch.
Plug the other end of the power adapter into a grounded, 3-pin
socket, AC power source.
Check the front-panel LEDs as the device powers on to confirm that
the PWR LED is green. If not, check that the power cable is correctly
plugged in.
If the PC IP address is different from the switch but is on the same
subnet, go to the next step. (For example, if the PC and switch both
have addresses that start with 192.168.1.x.) Otherwise, manually
set the IP address for the PC. See "Changing a PC IP address"
(page 96).

Setting the IP address
You can use an IP address to manage access to the switch over your
network. By default, the switch uses Dynamic Host Configuration Protocol
(DHCP) to assign IP settings to the management VLAN. (Default: VLAN
1.) If you want to manually configure IP settings, the IP address and subnet
mask must be compatible with your network. You may also need to establish
a default gateway between the switch and management stations that exist
on another network segment.
You can manually configure a specific IP address or direct the device to
obtain an address from a Bootstrap Protocol (BOOTP) or DHCP server.
Valid IP addresses consist of four decimal numbers, 0 to 255, separated by
periods. This is the only format that the Web-based user interface accepts.

that port.
To use port security, specify a maximum number of addresses to allow on
the port and then let the switch dynamically learn the source pair—MAC
address, VLAN—for frames received on the port. See "Configuring 802.1X
port settings" (page 88). You can also manually add secure addresses to the
port by using the Static Address table. See "Setting static addresses" (page
85). When the port reaches the maximum number of MAC addresses, the
selected port stops learning. The MAC addresses already in the address
table are retained and do not age out. Any other device that attempts to use
the port is prevented from accessing the switch.
A secure port:
•
cannot use port monitoring
•
cannot be a multi-VLAN port
•
cannot be used as a member of a static or dynamic trunk
•
should not be connected to a network interconnection device

as the Element Manager. You can specify up to five management stations
to receive authentication failure messages and other notification messages
from the switch.
By default, the switch issues notifications as trap messages. The recipient
of a trap message does not send a response to the switch. Therefore,
traps are not reliable as inform messages, which include a request for
acknowledgement of receipt. Informs can be used to ensure that the host
receives critical information. However, inform messages consume more
system resources because they must be kept in memory until a response is
received. Inform messages also add to network traffic.
If you specify an SNMP version 3 host, then the Trap Manager Community
String is interpreted as an SNMP user name. If you use SNMP version 3
authentication or encryption options (authNoPriv or authPriv), you must
first define the user name in the SNMP version 3 Users page to enable
password authentication and SNMP access to the switch. However, if
you specify a SNMP version 3 host with the no authentication (noAuth)
option, an SNMP user account is automatically generated, and the switch
authorizes SNMP access for the host.

Using the Nortel Business Ethernet Switch 50 Series
Before you make any physical connections between devices, use the
Web-based user interface to specify the trunk on the devices at both
ends.
•
To avoid creating loops, configure the port trunks completely before you
connect the corresponding network cables between switches.
•
Configure the ports at both ends of a connection as trunk ports.
•
Ensure that static trunks on switches of different types are compatible
with the IEEE802.3ad link aggregation standard.
•
Configure the ports at both ends of a trunk in an identical manner,
including communication mode (speed, duplex mode, and flow control),
Virtual Local Area Network (VLAN) assignments, and Class Of Service
(CoS) settings.
•
Ensure that all trunk ports have the same media type (for example, all
100BASE-T or all 1000BASE-TX).
•Treat all the portsin a trunk as a whole when moving, adding, or deleting
them to or from a VLAN.
Creating trunk groups 57
Configuring a static trunk
Use this procedure to configure static trunks. You can create up to six trunks
on the switch, with up to four ports for each trunk.
When you configure static trunks, keep in mind the following:
•
You may not be able to link switches of different types, depending on
the manufacturer’s implementation.
•Spanning Tree Algorithm (STA), VLAN, and IGMP settings can only
be configured for the entire trunk.
•
Static trunks on the BES50 are IEEE802.3ad link aggregationcompatible.
Prerequisites

To avoid creating a loop in the network:
— Add a static trunk through the configuration interface before you
connect the ports.
— Disconnect the ports before you remove a static trunk through the
configuration interface.

•
A trunk formed with another switch by using LACP is automatically
assigned to the next available trunk ID.
•
If more than four ports attached to the same target switch are
LACP-enabled, the additional ports are placed in standby mode and are
enabled only if one of the active links fails.

Setting the switch power budget
Use this procedure to define the Power over Ethernet (PoE) power budget
for the switch.
You can define a maximum PoE power budget for the switch (power
available to all switch ports) so that power can be centrally managed,
preventing overload conditions at the power source. If the power demand
from devices connected to the switch exceeds the power budget setting, the
switch uses port power priority settings to limit the supplied power.

Using the Nortel Business Ethernet Switch 50 Series
PriorityType the bridge priority used in selecting the root device, root port,
and designated port. The device with the highest priority becomes
the STA root device. However, if all devices have the same
priority, the device with the lowest MAC address becomes the root
device. Lower numeric values indicate higher priority. (Default:
32 768. Range: 0 to 61 440 in increments of 1 for 802.1D format,
or increments of 4 096 for 802.1t format. Options for 802.1t format:
0, 4 096, 8 192, 12 288, 16 384, 20 480, 24 576, 28 672, 32 768,

When the Switch Becomes Root
Hello TimeType the interval (in seconds) at which this device transmits a
configuration message. (Default: 2. Minimum: 1. Maximum: The
lower of 10 or [{Max. Message Age / 2} -1])
Maximum AgeType the maximum time (in seconds) a device can wait
without receiving a configuration message before attempting to
reconfigure. All device ports (except for designated ports) should
receive configuration messages at regular intervals. Any port
that ages out STA information (provided in the last configuration
message) becomes the designated port for the attached Local
Area Network (LAN). If it is a root port, a new root port is selected
from among the device ports attached to the network. (In this
instance, the term
ports refers to both ports and trunks.) (Default:
20. Minimum: The higher of 6 or [2 x {Hello Time + 1}]. Maximum:
The lower of 40 or [2 x {Forward Delay—1}])
Forward DelayType the maximum time (in seconds) the device waits before
changing states. (For example, changing from discarding to
learning to forwarding). Every device must receive information
about topology changes before it starts to forward frames. In
addition, each port needs time to listen for conflicting information
that can cause it to return to a discarding state resulting in
temporary data loops. (Default: 15. Minimum: The higher of 4 or
[{Max. Message Age / 2} + 1]. Maximum: 30)
Advanced
Path Cost MethodSelect the best path between devices. (Default: Long)
This option determines the range of values that can be assigned
to each interface:
•
Long: Specifies 32-bit based values ranging from 1 to
200 000 000.
•
Short: Specifies 16-bit based values ranging from 1 to 65 535.
Transmission LimitType the minimum interval between the transmission of
consecutive protocol messages. This is the maximum
transmission rate for Bridge Protocol Data Units (BPDUs).
(Range: 1 to 10. Default: 3.)
Using the Nortel Business Ethernet Switch 50 Series
Use this procedure to configure Spanning Tree Protocol (STP) attributes
for specific interfaces. In this procedure, the term interfaces refers to both
ports and trunks.
You can use a different priority or path cost for ports of the same media
type to indicate the preferred path, a link type to indicate a point-to-point
connection or shared-media connection, and an edge port to indicate if the
attached device can support fast-forwarding.

Variable definitions
VariableValue
PortThe port number.
Spanning TreeSelect to enable STA on this interface. (Default: Enabled)
STA StateIndicates the current state of this port within the Spanning Tree
Protocol:
•
Discarding—Port receives STA configuration messages, but
does not forward packets.
•
Learning—Port has transmitted configuration messages for an
interval set by the Forward Delay parameter without receiving
contradictory information. Port address table is cleared and
the port begins learning addresses.
•
Forwarding—Port forwards packets and continues learning
addresses.
Using the Nortel Business Ethernet Switch 50 Series
PriorityType the priority to use for this port in the Spanning Tree Protocol.
If the path cost for all ports on a switch is the same, the port with
the highest priority (lowest value) is configured as an active link in
the Spanning Tree Protocol. This makes a port with higher priority
less likely to be blocked if the Spanning Tree Protocol detects
network loops. Where more than one port is assigned the highest
priority, the port with lowest numeric identifier is enabled. (Default:
128. Range: 0 to 240, in increments of 16.)
Admin Path CostType the value to establish the best path between devices. Assign
lower values to ports attached to faster media, and assign higher
values to ports with slower media. Path cost takes precedence
over port priority. When the Path Cost Method is set to short, the
maximum path cost is 65 535.
Ranges:
Admin Link TypeSelect the link type attached to this interface as follows:
•
Point-to-Point—To connect to exactly one other bridge.
•
Shared—To connect to two or more bridges.
•
Auto—To configure the switch to automatically determine the
link type.
(Default: Auto)
Admin Edge Port
(Fast Forwarding)
If the interface is connected to an end-node device, or to a LAN
segment that is at the end of a bridged LAN, select to enable.
Because end nodes cannot cause forwarding loops, they can pass
directly through to the spanning tree forwarding state. Specifying
edge ports provides quicker convergence for devices such as
workstations or servers, retains the current forwarding database to
reduce the amount of frame flooding required to rebuild address
tables during reconfiguration events, does not cause the spanning
tree to initiate reconfiguration when the interface changes state,
and also overcomes other STA-related timeout problems. (Default:
Disabled)
Using the Nortel Business Ethernet Switch 50 Series
MigrationSelect to enable manual rechecking of the appropriate BPDU
format (RSTP or STP-compatible) to send on the selected
interfaces.
If Migration is disabled, the switch detects STA BPDUs
including configuration or topology change notification BPDUs; it
automatically sets the selected interface to forced STP-compatible
mode. (Default: Disabled)
TrunkIndicates if a port is a member of a trunk.

Assigning ports to VLANs
Before you enable VLANs for the switch, you must first assign each port
to the VLAN groups in which it will participate. By default, all ports are
assigned to VLAN 1 as untagged ports.
Add a port as a tagged port if you want the port to carry traffic for one or
more VLANs, and for any intermediate network devices, or for the host at
the other end of the connection support VLANs. Assign ports on the other
VLAN-aware network devices along the path to carry this traffic to the same
VLANs, either manually or dynamically by using Generic VLAN Registration
Protocol (GVRP).
Add a port as an untagged port if you want the port to participate in one or
more VLANs, but not on the intermediate network devices nor on the host at
the other end of the connection support VLANs.
You can assign ports to:
•
multiple tagged VLANs on the BES50FE-12/24T and the
BES50GE12/24T
•multiple untagged VLANs on the BES50FE-12/24T
•
only one untagged VLAN on the BES50GE12/24T
Using the Nortel Business Ethernet Switch 50 Series
For BES50GE-12/24T, if a port is an untagged member of VLAN 1, making
it an untagged member of VLAN 2 disassociates it from VLAN 1. The same
result occurs from VLAN 2 to VLAN 1.
VLAN-tagged frames can pass through VLAN-aware or VLAN-unaware network
interconnection devices, but the VLAN tags should be stripped off before passing
the VLAN-tagged frames on to any end-node host that does not support VLAN
tagging.

Assign ports as tagged if they are connected to 802.1Q VLAN compliant
devices, or untagged if they are not connected to any VLAN-aware devices.
Or, configure a port as forbidden to prevent the switch from automatically
adding it to a VLAN through the GVRP.
You can also use the VLAN Static Membership by Port page to configure
VLAN groups based on the port index. However, this configuration page
can add ports to VLANs only as tagged members.

Configuring VLAN behavior for interfaces
Use this procedure to configure VLAN behavior for specific interfaces,
including the default Port VLAN Identifier (PVID), accepted frame types,
ingress filtering, GVRP status, and Generic Attribute Resolution Protocol
(GARP) timers.
GARP VLAN Registration Protocol defines a way for switches to exchange
VLAN information to automatically register VLAN members on interfaces
across the network.
GVRP and GARP Multicast Registration Protocol (GMRP) use GARP to
register or deregister client attributes for client services within a bridged
LAN. The default values for the GARP timers are independent of the media
access method or data rate. Do not change these values unless you are
experiencing difficulties with GMRP or GVRP registration or deregistration.
Prerequisites
•
At least one port on the switch must be a member of the VLAN.
•
At least one member port of the VLAN must be in the Spanning Tree
Protocol Forwarding state.

Using the Nortel Business Ethernet Switch 50 Series
PVIDType the VLAN ID assigned to untagged frames received on the
interface.
If an interface is not a member of VLAN 1 and you assign its PVID
to this VLAN, the interface is automatically added to VLAN 1 as
an untagged member. For all other VLANs, an interface must first
be configured as an untagged member before you can assign its
PVID to that group. (Default: 1)
Acceptable Frame TypeSelect frame types accepted by the interface. When set to receive
all frame types, any untagged frames are assigned to the default
VLAN. (Option: All, Tagged; Default: All)
Ingress FilteringDetermines how to process frames tagged for VLANs for which
the ingress port is not a member:
•
Ingress filtering only affects tagged frames.
•
Ingress filtering does not affect VLAN independent BPDU
frames, such as GVRP or STA. However, ingress filtering
does affect VLAN dependent BPDU frames, such as GMRP.
Select to enable ingress filtering and to direct ports to discard
frames tagged for VLANs for which they are not a member. If
ingress filtering is disabled, frames tagged for VLANs for which
they are not a member are flooded to all other ports, except for
those VLANs explicitly forbidden on this port. (Default: Disabled)
GVRP StatusSelect to enable GVRP for the interface. GVRP must be globally
enabled for the switch before this setting can take effect. When
disabled, any GVRP packets received on this port are discarded
and no GVRP registrations are propagated from other ports.
(Default: Disabled)
GARP Join TimerType the interval between transmitting requests and queries to
participate in a VLAN group. (Range: 20 to 1 000 centiseconds.
Default: 20)
GARP Leave TimerType the interval a port waits before leaving a VLAN group. Set
this time to more than twice the join time, to ensure that the
applicants can rejoin before the port actually leaves the group
after a Leave or LeaveAll message is issued. (Range: 60 to 3 000
centiseconds. Default: 60)
GARP LeaveAll TimerType the interval between sending out a LeaveAll query message
for VLAN group participants and the port leaving the group. Set
this interval to be considerably larger than the Leave Timer to
minimize the amount of traffic generated by nodes rejoining the
group. (Range: 500 to 18 000 centiseconds. Default: 1 000)

Configuring address tables
Switches store the addresses for all known devices. This information passes
traffic directly between the inbound and outbound ports. The dynamic
address table stores all addresses learned by monitoring traffic. You can
also manually configure static addresses bound to a specific port.

Configuring Access Control Lists
Use these procedures to configure Access Control Lists (ACL) to provide
packet filtering for IP frames (based on address, protocol, Layer 4 protocol
port number, or TCP control code). To filter incoming packets, first create an
access list, add the required rules, specify a mask to modify the precedence
in which the rules are checked, and then bind the list to a specific port.

type. (Format: xxx.xxx.xxx.xxx)
Subnet MaskFor IP address type, type a subnet mask. The mask is
automatically generated if Any is the selected address type. The
subnet mask contains four integers from 0 to 255, each separated
by a period. The mask uses 1 bits to indicate match and 0 bits to
indicate ignore. The mask is bitwise ANDed with the specified
source IP address and compared with the address for each IP
packet entering the ports to which this ACL is assigned. (Format:
xxx.xxx.xxx.xxx)

ATTENTION
Address bits from the source/destination port are ANDed with
the corresponding bit positions in the source/destination port
bitmask. This produces a correct value that has bits set in all
positions where a bit is set in the supplied address.
Using the Nortel Business Ethernet Switch 50 Series
After you configure the Access Control Lists (ACL), you can bind the ports
that need to filter traffic to the appropriate ACLs. The switch supports ACLs
for only ingress filtering. However, you can only bind one IP ACL to any port
for ingress filtering. This means that only one ACL can be bound to an
interface—Ingress IP ACL.
Prerequisites
•
ACL must be configured before you can bind it to a port.
•
A mask must be configured for an ACL.
If the IP address type is Any, the mask is automatically generated.
