Initial
Configuration
This chapter instructs you how to configure and manage the GEP-2651 through the
web user interface. With this facility, you can easily access and monitor through any
one port of the switch all the status of the switch, including MIBs status, each port
activity, Spanning tree status, port aggregation status, multicast traffic, VLAN and
priority status, even illegal access record and so on.
The default values of the GEP-2651 are listed in the table below:
After the GEP2651 has been finished configuration the it interface, you can browse it.
For instance, type http://192.168.1.1 in the address row in a browser, it will show the
following screen and ask you inputting username and password in order to login and
access authentication.
The default username is “admin” and password is “admin”. For the first time to use,
please enter the default username and password, and then click the <Login> button.
The login process now is completed. In this login menu, you have to input the complete
username and password respectively, the GEP-2651 will not give you a shortcut to
username automatically. This looks inconvenient, but safer.
In the GEP-2651, allowed two or more users using administrator’s identity to manage
this switch, which administrator to do the last setting, it will be an available
configuration to effect the system.

information on how to contact this person. The allowed string length is 0 to 128, and the
allowed content is the ASCII characters from 32 to 126.
l System name:
An administratively assigned name for this managed node. By convention, this is the
node's fully-qualified domain name. A domain name is a text string drawn from the alphabet
(A-Za-z), digits (0-9), minus sign (-). No space characters are permitted as part of a name.
The first character must be an alpha character. And the first or last character must not be a
minus sign. The allowed string length is 0 to 128.

2-1.2 IP
The IPv4 address for the switch could be obtained via DHCP Server for VLAN 1. To manually
configure an address, you need to change the switch's default settings to values that are
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.
Configure the switch-managed IP information on this page
Configure IP basic settings, control IP interfaces and IP routes.
The maximum number of interfaces supported is 8 and the maximum number of routes is 32.

Configure whether the IP stack should act as a Host or a Router. In Host mode, IP traffic
between interfaces will not be routed. In Router mode traffic is routed between all interfaces.
l DNS Server
This setting controls the DNS name resolution done by the switch. The following modes are
supported:
• From any DHCP interfaces
The first DNS server offered from a DHCP lease to a DHCP-enabled interface will be
used.
• No DNS server
No DNS server will be used.
• Configured
Explicitly provide the IP address of the DNS Server in dotted decimal notation.
• From this DHCP interface
Specify from which DHCP-enabled interface a provided DNS server should be
preferred.
l DNS Proxy
When DNS proxy is enabled, system will relay DNS requests to the currently configured
DNS server, and reply as a DNS resolver to the client devices on the network.
IP Interfaces
l Delete
Select this option to delete an existing IP interface.
l VLAN
The VLAN associated with the IP interface. Only ports in this VLAN will be able to access
the IP interface. This field is only available for input when creating an new interface.
l IPv4 DHCP Enabled
Enable the DHCP client by checking this box. If this option is enabled, the system will
configure the IPv4 address and mask of the interface using the DHCP protocol. The DHCP
client will announce the configured System Name as hostname to provide DNS lookup.
l IPv4 DHCP Fallback Timeout
The number of seconds for trying to obtain a DHCP lease. After this period expires, a
configured IPv4 address will be used as IPv4 interface address. A value of zero disa bles the
fallback mechanism, such that DHCP will keep retrying until a valid lease is obtained. Legal
values are 0 to 4294967295 seconds.
l IPv4 DHCP Current Lease
For DHCP interfaces with an active lease, this column show the current interface address,
as provided by the DHCP server.
l IPv4 Address
The IPv4 address of the interface in dotted decimal notation.
If DHCP is enabled, this field is not used. The field may also be left blank if IPv4 operation
on the interface is not desired.
l IPv4 Mask
The IPv4 network mask, in number of bits (prefix length). Valid values are between 0 and
30 bits for a IPv4 address.
If DHCP is enabled, this field is not used. The field may also be left blank if IPv4 operation
on the interface is not desired.
l IPv6 Address
The IPv6 address of the interface. A IPv6 address is in 128-bit records represented as
eight fields of up to four hexadecimal digits with a colon separating each field (:). For
example, fe80::215:c5ff:fe03:4dc7. The symbol :: is a special syntax that can be used as a
shorthand way of representing multiple 16-bit groups of contiguous zeros; but it can
appear only once. It can also represent a legally valid IPv4 address. For
example, ::192.1.2.34.
The field may be left blank if IPv6 operation on the interface is not desired.

2-1.3 NTP
NTP is Network Time Protocol and is used to sync the network time based Greenwich Mean
Time (GMT). If use the NTP mode and select a built-in NTP time server or manually specify an
user-defined NTP server as well as Time Zone, the switch will sync the time in a short after
pressing <Apply> button. Though it synchronizes the time automatically, NTP does not update
the time periodically without user’s processing.
Time Zone is an offset time off GMT. You have to select the time zone first and then perform
time sync via NTP because the switch will combine this time zone offset and updated NTP time
to come out the local time, otherwise, you will not able to get the correct time. The switch
supports configurable time zone from –12 to +13 step 1 hour.
Default Time zone: +8 Hrs.
Web Interface
To configure NTP in the web interface:
1. Click Configuration, System, NTP.
2. Specify the Time parameter in manual parameters.

represented as eight fields of up to four hexadecimal digits with a colon separating each field
(:). For example, 'fe80::215:c5ff:fe03:4dc7'. The symbol '::' is a special syntax that can be
used as a shorthand way of representing multiple 16-bit groups of contiguous zeros; but it
can only appear once. It can also represent a legally valid IPv4 address. For example,
'::192.1.2.34'.

2-2 Green Ethernet
EEE is a power saving option that reduces the power usage when there is low or no traffic
utilization.
EEE works by powering down circuits when there is no traffic. When a port gets data to be
transmitted all circuits are powered up. The time it takes to power up the circuits is named
wakeup time. The default wakeup time is 17 us for 1Gbit links and 30 us for other link speeds.
Revision A1
Page 24
15
EEE devices must agree upon the value of the wakeup time in order to make sure that both the
receiving and transmitting device has all circuits powered up when traffic is transmitted. The
devices can exchange wakeup time information using the LLDP protocol.
EEE works for ports in auto-negotiation mode, where the port is negotiated to either 1G or 100
Mbit full duplex mode.
For ports that are not EEE-capable the corresponding EEE checkboxes are grayed out and
thus impossible to enable EEE for.
When a port is powered down for saving power, outgoing traffic is stored in a buffer until the
port is powered up again. Because there are some overhead in turning the port down and up,
more power can be saved if the traffic can be buffered up until a large burst of traffic can be
transmitted. Buffering traffic will give some latency in the traffic.
Web Interface
To c o nf ig u re a P o rt P o we r S av in g C on f ig ur at i on i n t he w eb in te r fa ce :
1. Click Configuration, Green Ethernet
2. Evoke to enable or disable the ActiPHY, PerfectReach, EEE and EEE Urgent Queues .
3. Click Apply.

Optimize EEE for
The switch can be set to optimize EEE for either best power saving or least traffic latency.
l Port:
The switch port number of the logical port.
Revision A1
Page 25
16
l ActiPHY :
Link down power savings enabled.
ActiPHY works by lowering the power for a port when there is no link. The port is power up
for short moment in order to determine if cable is inserted.
l PerfectReach :
Cable length power savings enabled.
PerfectReach works by determining the cable length and lowering the power for ports with
short cables.
l EEE :
Controls whether EEE is enabled for this switch port.
For maximizing power savings, the circuit isn't started at once transmit data is ready for a
port, but is instead queued until a burst of data is ready to be transmitted. This will give some
traffic latency.
If desired it is possible to minimize the latency for specific frames, by mapping the frames to
a specific queue (done with QOS), and then mark the queue as an urgent queue. When an
urgent queue gets data to be transmitted, the circuits will be powered up at once and the
latency will be reduced to the wakeup time.
l EEE Urgent Queues :
Queues set will activate transmission of frames as soon as data is available. Otherwise the
queue will postpone transmission until a burst of frames can be transmitted.

2-5.1.5 SNMP
Any Network Management System (NMS) running the Simple Network Management Protocol
(SNMP) can manage the Managed devices equipped with SNMP agent, provided that the
Management Information Base (MIB) is installed correctly on the managed devices. The SNMP
is a protocol that is used to govern the transfer of information between SNMP manager and
agent and traverses the Object Identity (OID) of the management Information Base (MIB),
described in the form of SMI syntax. SNMP agent is running on the switch to response the
request issued by SNMP manager.
Basically, it is passive except issuing the trap information. The switch supports a switch to turn
on or off the SNMP agent. If you set the field SNMP “Enable”, SNMP agent will be started up.
All supported MIB OIDs, including RMON MIB, can be accessed via SNMP manager. If the field
SNMP is set “Disable”, SNMP agent will be de-activated, the related Community Name, Trap
Host IP Address, Trap and all MIB counters will be ignored.
2-5.1.5.1 System
This section describes how to configure SNMP System on the switch. This function is used to
configure SNMP settings, community name, trap host and public traps as well as the throttle
of SNMP. A SNMP manager must pass the authentication by identifying both community
names, then it can access the MIB information of the target device. So, both parties must have
the same community name. Once completing the setting, click <Apply> button, the setting
takes effect.

Security Model (USM) for message security and the View-based Access Control Model
(VACM) for access control. For the USM entry, the usmUserEngineID and usmUserName
are the entry's keys. In a simple agent, usmUserEngineID is always that agent's own
snmpEngineID value. The value can also take the value of the snmpEngineID of a remote
SNMP engine with which this user can communicate. In other words, if user engine ID equal
system engine ID then it is local user; otherwise it's remote user.

2-5.2.1 Limit Control
This section shows you to to configure the Port Security settings of the Switch. You can use
the Port Security feature to restrict input to an interface by limiting and identifying MAC
addresses.
Web Interface
To c o nf ig u re a C o nf ig u ra ti o n of Limit Control in the web interface:
1. Select “Enabled” in the Mode of System Configuration.
2. Checked Aging Enabled.
3. Set Aging Period (Default is 3600 seconds).
To c o nf ig u re a P o rt C o nf ig ur a ti on of Limit Control in the web interface:
1. Select “Enabled” in the Mode of Port Configuration.
2. Specify the maximum number of MAC addresses in the Limit of Port Configuration.
3. Set Ation (Trap, Shutdown, Trap & Shutdown)
4. Click Apply.
Figure 2-5.2.1: The Port Security Limit Control Configuration
Revision A1
Page 63
55
Parameter description:
System Configuration
l Mode :
Indicates if Limit Control is globally enabled or disabled on the switch. If globally disabled,
other modules may still use the underlying functionality, but limit checks and corresponding
actions are disabled.
l Aging Enabled :
If checked, secured MAC addresses are subject to aging as discussed under Aging Period .
l Aging Period :
If Aging Enabled is checked, then the aging period is controlled with this input. If other
modules are using the underlying port security for securing MAC addresses, they may have
other requirements to the aging period. The underlying port security will use the shorter
requested aging period of all modules that use the functionality.
The Aging Period can be set to a number between 10 and 10,000,000 seconds.
To u n de r st a nd wh y a gi ng m a y b e de si re d, co n si d er t h e fo ll ow in g s ce n ar i o: S u pp o se a n en d host is connected to a 3rd party switch or hub, which in turn is connected to a port on this
switch on which Limit Control is enabled. The end-host will be allowed to forward if the limit
is not exceeded. Now suppose that the end-host logs off or powers down. If it wasn't for
aging, the end-host would still take up resources on this switch and will be allowed to forward.
To o ve r co m e t hi s s it ua t io n, e n ab l e a g in g . W i th a g in g e na b le d , a t i me r is s ta rt ed o nc e t he
end-host gets secured. When the timer expires, the switch starts looking for frames from the
end-host, and if such frames are not seen within the next Aging Period, the end-host is
assumed to be disconnected, and the corresponding resources are freed on the switch.
Port Configuration
The table has one row for each port on the selected switch and a number of columns, which
are:
l Port :
The port number to which the configuration below applies.
l Mode :
Controls whether Limit Control is enabled on this port. Both this and the Global Mode must
be set to Enabled for Limit Control to be in effect. Notice that other modules may still use the
underlying port security features without enabling Limit Control on a given port.
l Limit :
The maximum number of MAC addresses that can be secured on this port. This number
cannot exceed 1024. If the limit is exceeded, the corresponding action is taken.
The switch is "born" with a total number of MAC addresses from which all ports draw
whenever a new MAC address is seen on a Port Security-enabled port. Since all ports draw
from the same pool, it may happen that a configured maximum cannot be granted, if the
remaining ports have already used all available MAC addresses.
l Action :
If Limit is reached, the switch can take one of the following actions:
None: Do not allow more than Limit MAC addresses on the port, but take no further action.
Trap: If Limit + 1 MAC addresses is seen on the port, send an SNMP trap. If Aging is disabled,
only one SNMP trap will be sent, but with Aging enabled, new SNMP traps will be sent every
time the limit gets exceeded.
Shutdown: If Limit + 1 MAC addresses is seen on the port, shut down the port. This implies
that all secured MAC addresses will be removed from the port, and no new address will be
learned. Even if the link is physically disconnected and reconnected on the port (by
disconnecting the cable), the port will remain shut down. There are three ways to re-open
the port:
Revision A1
Page 64

1) Boot the switch,
NOTE: That clicking the reopen button causes the page to be
refreshed, so non-committed changes will be lost
2) Disable and re-enable Limit Control on the port or the switch,
3) Click the Reopen button.
Trap & Shu tdown: If Limit + 1 MAC addresses is seen on the port, both the "Trap" and the
"Shutdown" actions described above will be taken.
l State :
This column shows the current state of the port as seen from the Limit Control's point of view.
The state takes one of four values:
Disabled: Limit Control is either globally disabled or disabled on the port.
Ready: The limit is not yet reached. This can be shown for all actions.
Limit Reached: Indicates that the limit is reached on this port. This state can only be shown
if Action is set to None or Trap.
Shutdown: Indicates that the port is shut down by the Limit Control module. This state can
only be shown if Action is set to Shutdown or Trap & Shutdown.
l Re-open Button :
If a port is shutdown by this module, you may reopen it by clicking this button, which will only
be enabled if this is the case. For other methods, refer to Shutdown in the Action section.

Parameter description:
l Mode :
Indicates if NAS is globally enabled or disabled on the switch. If globally disabled, all ports
are allowed forwarding of frames.
l Reauthentication Enabled :
If checked, successfully authenticated supplicants/clients are reauthenticated after the
interval specified by the Reauthentication Period. Reauthentication for 802.1X-enabled ports
can be used to detect if a new device is plugged into a switch port or if a supplicant is no
longer attached.
For MAC-based ports, reauthentication is only useful if the RADIUS server configuration has
changed. It does not involve communication between the switch and the client, and therefore
doesn't imply that a client is still present on a port (see Aging Period below).
l Reauthentication Period :
Determines the period, in seconds, after which a connected client must be reauthenticated.
This is only active if the Reauthentication Enabled checkbox is checked. Valid values are in
the range 1 to 3600 seconds.
l EAPOL Timeout :
Determines the time for retransmission of Request Identity EAPOL frames.
Revision A1
Page 66
58
Valid v a lue s ar e in t h e range 1 to 2 5 5 seco n d s. This h as no e ffect f o r MAC-based ports.
l Aging Period :
This setting applies to the following modes, i.e. modes using the Port Security functionality
to secure MAC addresses:
• Single 802.1X
• Multi 802.1X
• MAC-Based Auth.
When the NAS module uses the Port Security module to secure MAC addresses, the Port
Security module needs to check for activity on the MAC address in question at regular
intervals and free resources if no activity is seen within a given period of time. This parameter
controls exactly this period and can be set to a number between 10 and 1000000 seconds.
If reauthentication is enabled and the port is in an 802.1X-based mode, this is not so critical,
since supplicants that are no longer attached to the port will get removed upon the next
reauthentication, which will fail. But if reauthentication is not enabled, the only way to free
resources is by aging the entries.
For ports in MAC-based Auth. mode, reauthentication doesn't cause direct communication
between the switch and the client, so this will not detect whether the client is still attached or
not, and the only way to free any resources is to age the entry.
l Hold Time :
This setting applies to the following modes, i.e. modes using the Port Security functionality
to secure MAC addresses:
• Single 802.1X
• Multi 802.1X
• MAC-Based Auth.
If a client is denied access - either because the RADIUS server denies the client access or
because the RADIUS server request times out (according to the timeout specified on the
"Configuration→Security→AAA" page) - the client is put on hold in the Unauthorized state.
The hold timer does not count during an on-going authentication.
In MAC-based Auth. mode, the The switch will ignore new frames coming from the client
during the hold time.
The Hold Time can be set to a number between 10 and 1000000 seconds.
l RADIUS-Assigned QoS Enabled :
RADIUS-assigned QoS provides a means to centrally control the traffic class to which traffic
coming from a successfully authenticated supplicant is assigned on the switch. The RADIUS
server must be configured to transmit special RADIUS attributes to take advantage of this
feature (see RADIUS-Assigned QoS Enabled below for a detailed description)
The "RADIUS-Assigned QoS Enabled" checkbox provides a quick way to globally
enable/disable RADIUS-server assigned QoS Class functionality. When checked, the
individual ports' ditto setting determine whether RADIUS-assigned QoS Class is enabled on
that port. When unchecked, RADIUS-server assigned QoS Class is disabled on all ports.
l RADIUS-Assigned VLAN Enabled :
RADIUS-assigned VLAN provides a means to centrally control the VLAN on which a
successfully authenticated supplicant is placed on the switch. Incoming traffic will be
classified to and switched on the RADIUS-assigned VLAN. The RADIUS server must be
configured to transmit special RADIUS attributes to take advantage of this feature (see
RADIUS-Assigned VLAN Enabled below for a detailed description).
The "RADIUS-Assigned VLAN Enabled" checkbox provides a quick way to globally
enable/disable RADIUS-server assigned VLAN functionality. When checked, the individual
ports' ditto setting determine whether RADIUS-assigned VLAN is enabled on that port. When
unchecked, RADIUS-server assigned VLAN is disabled on all ports.
l Guest VLAN Enabled :
A Gu est VLAN is a special VLAN - typically with limited network access - on which 802.1Xunaware clients are placed after a network administrator-defined timeout. The switch follows
Revision A1
Page 67
59
a set of rules for entering and leaving the Guest VLAN as listed below.
The "Guest VLAN Enabled" checkbox provides a quick way to globally enable/disable Guest
VLAN functionality. When checked, the individual ports' ditto setting determines whether the
port can be moved into Guest VLAN. When unchecked, the ability to move to the Guest
VLAN is disabled on all ports.
l Guest VLAN ID :
This is the value that a port's Port VLAN ID is set to if a port is moved into the Guest VLAN.
It is only changeable if the Guest VLAN option is globally enabled.
Valid v a lue s ar e in t h e range [1; 40 9 5].
l Max. Reauth. Count :
The number of times the switch transmits an EAPOL Request Identity frame without
response before considering entering the Guest VLAN is adjusted with this setting. The value
can only be changed if the Guest VLAN option is globally enabled.
Valid v a lue s ar e in t h e range [1; 25 5 ].
l Allow Guest VLAN if EAPOL Seen :
The switch remembers if an EAPOL frame has been received on the port for the life-time of
the port. Once the switch considers whether to enter the Guest VLAN, it will first check if this
option is enabled or disabled. If disabled (unchecked; default), the switch will only enter the
Guest VLAN if an EAPOL frame has not been received on the port for the life-time of the
port. If enabled (checked), the switch will consider entering the Guest VLAN even if an
EAPOL frame has been received on the port for the life-time of the port.
The value can only be changed if the Guest VLAN option is globally enabled.
l Port Configuration :
The table has one row for each port on the selected switch and a number of columns, which
are:
l Port :
The port number for which the configuration below applies.
l Admin State :
If NAS is globally enabled, this selection controls the port's authentication mode. The
following modes are available:
l Force Authorized :
In this mode, the switch will send one EAPOL Success frame when the port link comes up,
and any client on the port will be allowed network access without authentication.
l Force Unauthorized :
In this mode, the switch will send one EAPOL Failure frame when the port link comes up,
and any client on the port will be disallowed network access.
l Port-based 802.1X :
In the 802.1X-world, the user is called the supplicant, the switch is the authenticator, and the
RADIUS server is the authentication server. The authenticator acts as the man-in-the-middle,
forwarding requests and responses between the supplicant and the authentication server.
Frames sent between the supplicant and the switch are special 802.1X frames, known as
EAPOL (EAP Over LANs) frames. EAPOL frames encapsulate EAP PDUs (RFC3748).
Frames sent between the switch and the RADIUS server are RADIUS packets. RADIUS
packets also encapsulate EAP PDUs together with other attributes like the switch's IP
address, name, and the supplicant's port number on the switch. EAP is very flexible, in that
it allows for different authentication methods, like MD5-Challenge, PEAP, and TLS. The
important thing is that the authenticator (the switch) doesn't need to know which
authentication method the supplicant and the authentication server are using, or how many
information exchange frames are needed for a particular method. The switch simply
encapsulates the EAP part of the frame into the relevant type (EAPOL or RADIUS) and
forwards it.
When authentication is complete, the RADIUS server sends a special packet containing a
Revision A1
Page 68
60
success or failure indication. Besides forwarding this decision to the supplicant, the switch
NOTE: Suppose two backend servers are enabled and that the
server timeout is configured to X seconds (using the AAA
configuration page), and suppose that the first server in the list is
currently down (but not considered dead).
Now, if the supplicant retransmits EAPOL Start frames at a rate faster
than X seconds, then it will never get authenticated, because the
switch will cancel on-going backend authentication server requests
whenever it receives a new EAPOL Start frame from the supplicant.
And since the server hasn't yet failed (because the X seconds haven't
expired), the same server will be contacted upon the next backend
authentication server request from the switch. This scenario will loop
forever. Therefore, the server timeout should be smaller than the
supplicant's EAPOL Start frame retransmission rate.
uses it to open up or block traffic on the switch port connected to the supplicant
l Single 802.1X :
In port-based 802.1X authentication, once a supplicant is successfully authenticated on a
port, the whole port is opened for network traffic. This allows other clients connected to the
port (for instance through a hub) to piggy-back on the successfully authenticated client and
get network access even though they really aren't authenticated. To overcome this security
breach, use the Single 802.1X variant. Single 802.1X is really not an IEEE standard, but
features many of the same characteristics as does port-based 802.1X. In Single 802.1X, at
most one supplicant can get authenticated on the port at a time. Normal EAPOL frames are
used in the communication between the supplicant and the switch. If more than one
supplicant is connected to a port, the one that comes first when the port's link comes up will
be the first one considered. If that supplicant doesn't provide valid credentials within a certain
amount of time, another supplicant will get a chance. Once a supplicant is successfully
authenticated, only that supplicant will be allowed access. This is the most secure of all the
supported modes. In this mode, the Port Security module is used to secure a supplicant's
MAC address once successfully authenticated.
l Multi 802.1X :
In port-based 802.1X authentication, once a supplicant is successfully authenticated on a
port, the whole port is opened for network traffic. This allows other clients connected to the
port (for instance through a hub) to piggy-back on the successfully authenticated client and
get network access even though they really aren't authenticated. To overcome this security
breach, use the Multi 802.1X variant.
Multi 802.1X is really not an IEEE standard, but features many of the same characteristics
as does port-based 802.1X. Multi 802.1X is - like Single 802.1X - not an IEEE standard, but
a variant that features many of the same characteristics. In Multi 802.1X, one or more
supplicants can get authenticated on the same port at the same time. Each supplicant is
authenticated individually and secured in the MAC table using the Port Security module.
In Multi 802.1X it is not possible to use the multicast BPDU MAC address as destination
MAC address for EAPOL frames sent from the switch towards the supplicant, since that
would cause all supplicants attached to the port to reply to requests sent from the switch.
Instead, the switch uses the supplicant's MAC address, which is obtained from the first
l MAC-based Auth.:
EAPOL Start or EAPOL Response Identity frame sent by the supplicant. An exception to this
is when no supplicants are attached. In this case, the switch sends EAPOL Request Identity
frames using the BPDU multicast MAC address as destination - to wake up any supplicants
that might be on the port.
The maximum number of supplicants that can be attached to a port can be limited using the
Port Security Limit Control functionality.
Unlike port-based 802.1X, MAC-based authentication is not a standard, but merely a bestpractices method adopted by the industry. In MAC-based authentication, users are called
clients, and the switch acts as the supplicant on behalf of clients. The initial frame (any kind
Revision A1
Page 69
61
of frame) sent by a client is snooped by the switch, which in turn uses the client's MAC
address as both username and password in the subsequent EAP exchange with the RADIUS
server. The 6-byte MAC address is converted to a string on the following form "xx-xx-xx-xxxx-xx", that is, a dash (-) is used as separator between the lower-cased hexadecimal digits.
The switch only supports the MD5-Challenge authentication method, so the RADIUS server
must be configured accordingly.
When authentication is complete, the RADIUS server sends a success or failure indication,
which in turn causes the switch to open up or block traffic for that particular client, using the
Port Security module. Only then will frames from the client be forwarded on the switch. There
are no EAPOL frames involved in this authentication, and therefore, MAC-based
Authentication has nothing to do with the 802.1X standard.
The advantage of MAC-based authentication over port-based 802.1X is that several clients
can be connected to the same port (e.g. through a 3rd party switch or a hub) and still require
individual authentication, and that the clients don't need special supplicant software to
authenticate. The advantage of MAC-based authentication over 802.1X-based
authentication is that the clients don't need special supplicant software to authenticate. The
disadvantage is that MAC addresses can be spoofed by malicious users - equipment whose
MAC address is a valid RADIUS user can be used by anyone. Also, only the MD5-Challenge
method is supported. The maximum number of clients that can be attached to a port can be
limited using the Port Security Limit Control functionality.
l RADIUS-Assigned QoS Enabled :
When RADIUS-Assigned QoS is both globally enabled and enabled (checked) on a given
port, the switch reacts to QoS Class information carried in the RADIUS Access-Accept
packet transmitted by the RADIUS server when a supplicant is successfully authenticated.
If present and valid, traffic received on the supplicant's port will be classified to the given
QoS Class. If (re-)authentication fails or the RADIUS Access-Accept packet no longer carries
a QoS Class or it's invalid, or the supplicant is otherwise no longer present on the port, the
port's QoS Class is immediately reverted to the original QoS Class (which may be changed
by the administrator in the meanwhile without affecting the RADIUS-assigned).
This option is only available for single-client modes, i.e.
• Port-based 802.1X
• Single 802.1X
RADIUS attributes used in identifying a QoS Class:
Refer to the written documentation for a description of the RADIUS attributes needed in order
to successfully identify a QoS Class. The User-Priority-Ta bl e at tr ib u te de fi n ed in RFC4675
forms the basis for identifying the QoS Class in an Access-Accept packet.
Only the first occurrence of the attribute in the packet will be considered, and to be valid, it
must follow this rule:
• All 8 octets in the attribute's value must be identical and consist of ASCII characters in the
range '0' - '3', which translates into the desired QoS Class in the range [0; 3].
l RADIUS-Assigned VLAN Enabled :
When RADIUS-Assigned VLAN is both globally enabled and enabled (checked) for a given
port, the switch reacts to VLAN ID information carried in the RADIUS Access-Accept packet
transmitted by the RADIUS server when a supplicant is successfully authenticated. If present
and valid, the port's Port VLAN ID will be changed to this VLAN ID, the port will be set to be
a member of that VLAN ID, and the port will be forced into VLAN unaware mode. Once
assigned, all traffic arriving on the port will be classified and switched on the RADIUSassigned VLAN ID.
If (re-)authentication fails or the RADIUS Access-Accept packet no longer carries a VLAN ID
or it's invalid, or the supplicant is otherwise no longer present on the port, the port's VLAN
ID is immediately reverted to the original VLAN ID (which may be changed by the
administrator in the meanwhile without affecting the RADIUS-assigned).
This option is only available for single-client modes, i.e.
• Port-based 802.1X
• Single 802.1X
Revision A1
Page 70
62
For trouble-shooting VLAN assignments, use the "Monitor→VLANs→VLAN Membership
and VLAN Port" pages. These pages show which modules have (temporarily) overridden the
current Port VLAN configuration.
RADIUS attributes used in identifying a VLAN ID:
RFC2868 and RFC3580 form the basis for the attributes used in identifying a VLAN ID in an
Access-Accept packet. The following criteria are used:
• The Tunnel-Medium-Type, Tunnel-Type, and Tunnel-Private-Group-ID attributes must all
be present at least once in the Access-Accept packet.
• The switch looks for the first set of these attributes that have the same Tag value and fulfil
the following requirements (if Tag == 0 is used, the Tunnel-Private-Group-ID does not need
to include a Tag):
- Val u e of Tu nnel-Medium-Type must be set to "IEEE -802" (ordinal 6).
- Val u e of Tu nnel-Type must be set t o "VLAN" (ordinal 1 3).
- Valu e of Tun n e l-Private-Group-ID must be a string of ASCII chars in the range '0' - '9',
which is interpreted as a decimal string representing the VLAN ID. Leading '0's are discarded.
The final value must be in the range [1; 4095].
l Guest VLAN Enabled :
When Guest VLAN is both globally enabled and enabled (checked) for a given port, the
switch considers moving the port into the Guest VLAN according to the rules outlined below.
This option is only available for EAPOL-based modes, i.e.:
• Port-based 802.1X
• Single 802.1X
• Multi 802.1X
For trouble-shooting VLAN assignments, use the "Monitor→VLANs→VLAN Membership
and VLAN Port" pages. These pages show which modules have (temporarily) overridden the
current Port VLAN configuration.
Guest VLAN Operation:
When a Guest VLAN enabled port's link comes up, the switch starts transmitting EAPOL
Request Identity frames. If the number of transmissions of such frames exceeds Max.
Reauth. Count and no EAPOL frames have been received in the meanwhile, the switch
considers entering the Guest VLAN. The interval between transmission of EAPOL Request
Identity frames is configured with EAPOL Timeout. If Allow Guest VLAN if EAPOL Seen is
enabled, the port will now be placed in the Guest VLAN. If disabled, the switch will first check
its history to see if an EAPOL frame has previously been received on the port (this history is
cleared if the port link goes down or the port's Admin State is changed), and if not, the port
will be placed in the Guest VLAN. Otherwise it will not move to the Guest VLAN, but continue
transmitting EAPOL Request Identity frames at the rate given by EAPOL Timeout.
Once in the Guest VLAN, the port is considered authenticated, and all attached clients on
the port are allowed access on this VLAN. The switch will not transmit an EAPOL Success
frame when entering the Guest VLAN.
While in the Guest VLAN, the switch monitors the link for EAPOL frames, and if one such
frame is received, the switch immediately takes the port out of the Guest VLAN and starts
authenticating the supplicant according to the port mode. If an EAPOL frame is received, the
port will never be able to go back into the Guest VLAN if the "Allow Guest VLAN if EAPOL
Seen" is disabled.
l Port State :
The current state of the port. It can undertake one of the following values:
Globally Disabled: NAS is globally disabled.

is authorized.
Unauthorized: The port is in Force Unauthorized or a single-supplicant mode and the
supplicant is not successfully authorized by the RADIUS server.

Two buttons are available for each row. The buttons are only enabled when aut hentic ation
is globally enabled and the port's Admin State is in an EAPOL-based or MAC-based mode.
Clicking these buttons will not cause settings changed on the page to take effect.
Reauthenticate: Schedules a reauthentication whenever the quiet-period of the port runs out
(EAPOL-based authentication). For MAC-based authentication, reauthentication will be
attempted immediately.
The button only has effect for successfully authenticated clients on the port and will not cause
the clients to get temporarily unauthorized.
Reinitialize: Forces a reinitialization of the clients on the port and thereby a reauthentication
immediately. The clients will transfer to the unauthorized state while the reauthentication is
in progress.

2-5.2.3 ACL
The Series switch access control list (ACL) is probably the most commonly used object in the
IOS. It is used for packet filtering but also for selecting types of traffic to be analyzed, forwarded,
or influenced in some way. The ACLs are divided into Ether Types. IPv4, ARP protocol, MAC
and VLAN parameters etc. Here we will just go over the standard and extended access lists for
TCP/IP. As you create ACEs for ingress classification, you can assign a policy for each port,
the policy number is 1-8, however, each policy can be applied to any port. This makes it very
easy to determine what type of ACL policy you will be working with.

other more specific criteria. This switch tests ingress packets against the conditions in an ACL
one by one. A packet will be accepted as soon as it matches a permit rule, or dropped as soon
as it matches a deny rule. If no rules match, the frame is accepted. Other actions can also be
invoked when a matching packet is found, including rate limiting, copying matching packets to
another port or to the system log, or shutting down a port.

l Retransmit
Retransmit is the number of times, in the range 1 to 1000, a RADIUS request is retransmitted
to a server that is not responding. If the server has not responded after the last retransmit it
is considered to be dead.
l Deadtime
Deadtime, which can be set to a number between 0 to 1440 minutes, is the period during
which the switch will not send new requests to a server that has failed to respond to a
previous request. This will stop the switch from continually trying to contact a server that it
has already determined as dead.
Setting the Deadtime to a value greater than 0 (zero) will enable this feature, but only if more
than one server has been configured.

2-6 Aggregation
The Aggregation is used to configure the settings of Link Aggregation. You can bundle more
than one port with the same speed, full duplex and the same MAC to be a single logical port,
thus the logical port aggregates the bandwidth of these ports. This means you can apply your
current Ethernet equipment’s to build the bandwidth aggregation. For example, if there are
three Fast Ethernet ports aggregated in a logical port, then this logical port has bandwidth three
times as high as a single Fast Ethernet port has.
2-6.1 Static
Ports using Static Trunk as their trunk method can choose their unique Static GroupID to form
a logic “trunked port”. The benefit of using Static Trunk method is that a port can immediately
become a member of a trunk group without any handshaking with its peer port. This is also a
disadvantage because the peer ports of your static trunk group may not know that they should
be aggregate together to form a “logic trunked port”. Using Static Trunk on both end of a link is
strongly recommended. Please also note that low speed links will stay in “not ready” state when
using static trunk to aggregate with high speed links.
Web Interface
To configure the Trunk Aggregation Hash mode and Aggregation Group in the web interface:
1. Click Configuration, Aggregation, Static and then Aggregation Mode Configuration.

2-8 Spanning Tree
The Spanning Tree Protocol (STP) can be used to detect and disable network loops, and to
provide backup links between switches, bridges or routers. This allows the switch to interact
with other bridging devices (that is, an STP-compliant switch, bridge or router) in your network
to ensure that only one route exists between any two stations on the network, and provide
backup links which automatically take over when a primary link goes down.
STP - STP uses a distributed algorithm to select a bridging device (STP- compliant switch,
bridge or router) that serves as the root of the spanning tree network. It selects a root port on
each bridging device (except for the root device) which incurs the lowest path cost when
forwarding a packet from that device to the root device. Then it selects a designated bridging
device from each LAN which incurs the lowest path cost when forwarding a packet from that
LAN to the root device. All ports connected to designated bridging devices are assigned as
designated ports. After determining the lowest cost spanning tree, it enables all root ports and
designated ports, and disables all other ports. Network packets are therefore only forwarded
between root ports and designated ports, eliminating any possible network loops.
Once a stable network topology has been established, all bridges listen for Hello BPDUs
(Bridge Protocol Data Units) transmitted from the Root Bridge. If a bridge does not get a Hello
BPDU after a predefined interval (Maximum Age), the bridge assumes that the link to the Root
Bridge is down. This bridge will then initiate negotiations with other bridges to reconfigure the
network to reestablish a valid network topology.

l Bridge Priority :
Controls the bridge priority. Lower numeric values have better priority. The bridge priority
plus the MSTI instance number, concatenated with the 6-byte MAC address of the switch
forms a Bridge Identifier. For MSTP operation, this is the priority of the CIST. Otherwise, this
is the priority of the STP/RSTP bridge.
l Forward Delay :
The delay used by STP Bridges to transit Root and Designated Ports to Forwarding (used in
STP compatible mode). Valid values are in the range 4 to 30 seconds.
l Max Age :
The maximum age of the information transmitted by the Bridge when it is the Root Bridge.
Valid v a lue s ar e in t h e range 6 to 40 seconds, and MaxAge must be <= (FwdDelay-1)*2.
l Maximum Hop Count :
This defines the initial value of remaining Hops for MSTI information generated at the
boundary of an MSTI region. It defines how many bridges a root bridge can distribute its
BPDU information to. Valid values are in the range 6 to 40 hops.
l Tra nsmit Hold Count :
The number of BPDU's a bridge port can send per second. When exceeded, transmission
of the next BPDU will be delayed. Valid values are in the range 1 to 10 BPDU's per second.
