Local Counters

Label Description

Local Port The port on which LLDP frames are received or transmitted.

Tx Frames The number of LLDP frames transmitted on the port.

Rx Frames The number of LLDP frames received on the port.

Rx Errors The number of received LLDP frames containing some kind of error.

Frames Discarded

If an LLDP frame is received on a port, and the switch’s internal table has run full, the LLDP frame is counted and discarded. This situation is known as “Too Many Neighbors” in the LLDP standard. LLDP frames require a new entry in the table when the Chassis ID or Remote Port ID is not already contained within the table. Entries are removed from the table when a given port links down, an LLDP shutdown frame is received, or when the entry ages out.

TLVs Discarded Each LLDP frame can contain multiple pieces of information, known as TLVs (TLV is

short for “Type Length Value”). If a TLV is malformed, it is counted and discarded.

TLVs

The number of well-formed TLVs, but with an unknown type value.

Unrecognized

Org. Discarded The number of organizationally TLVs received.

Age-Outs Each LLDP frame contains information about how long time the LLDP information is

valid (age-out time). If no new LLDP frame is received within the age out time, the LLDP information is removed, and the Age-Out counter is incremental.

Redundancy

C-Ring

C-Ring is one of the most powerful Ring technologies in the world. The recovery time of C-Ring is less than 30 ms. It can reduce unexpected damage caused by network topology change. C-Ring supports 3 different Ring topologies: Ring, Coupling Ring and Dual Homing.

C-Ring interface

The following table describes the labels in this screen.

Label Description

C-Ring Mark to enable Ring.

Ring Master There should be one and only one Ring Master in a ring. However if there are two

or more switches which set Ring Master to enable, the switch with the lowest MAC address will be the actual Ring Master and others will be Backup Masters.

1st Ring Port The primary port, when this switch is Ring Master.

2nd Ring Port The backup port, when this switch is Ring Master.

Coupling Ring Mark to enable Coupling Ring. Coupling Ring can be used to divide a big ring into

two smaller rings to avoid effecting all switches when network topology change. It is a good application for connecting two Rings.

Coupling Port Link to Coupling Port of the switch in another ring. Coupling Ring needs four switches

to build an active and a backup link. Set a port as coupling port. The coupled four ports of four switches will be run in active/backup mode.

Dual Homing Mark to enable Dual Homing. By selecting Dual Homing mode, Ring will be connected

to normal switches through two RSTP links (ex: backbone Switch). The two links work as active/backup mode, and connect each Ring to the normal switches in RSTP mode.

Apply Click “Apply” to set the configurations.

Note: It is not recommended to set one switch as a Ring Master and a Coupling Ring at the same time due to heavy load.

This mode is normally used for ports connected to VLAN aware switches. Tx tag should be set to Untag_pvid when this mode is used. If Specific (the default value) is selected, a Port VLAN ID can be configured (see below). Untagged frames received on the port are classified to the Port VLAN ID. If VLAN awareness is disabled, all frames received on the port are classified to the Port VLAN ID. If the classified VLAN ID of a frame transmitted on the port is different from the Port VLAN ID, a VLAN tag with the classified VLAN ID is inserted in the frame.

Port VLAN ID Configures the VLAN identifier for the port. The allowed values are from 1 through

4095. The default value is 1.

Note: The port must be a member of the same VLAN as the Port VLAN ID.

Tx Tag Determines egress tagging of a port. Untag_pvid – All VLANs except the configured

PVID will be tagged. Tag_all – All VLANs are tagged. Untag_all – All VLANs are untagged.

Traffic Prioritization

Storm Control

There is a unicast storm rate control, multicast storm rate control, and a broadcast storm rate control. These only affect flooded frames, i.e. frames with a (VLAN ID, DMAC) pair not present on the MAC Address table.

The rate is 2^n, where n is equal to or less than 15, or “No Limit”. The unit of the rate can be either pps (packets per second) or kpps (kilopackets per second). The configuration indicates the permitted packet rate for unicast, multicast, or broadcast traffic across the switch.

Note: Frames, which are sent to the CPU of the switch are always limited to approximately 4 kpps. For example, broadcasts in the management VLAN are limited to this rate. The management VLAN is configured on the IP setup page.

QoS is an acronym for Quality of Service. It is a method to guarantee a bandwidth relationship between individual applications or protocols.

Label Description

Port The port number for which the configuration below applies

QoS Class Controls the default QoS class.

All frames are classified to a QoS class. There is a one to one mapping between QoS

class, queue and priority. A QoS class of 0 (zero) has the lowest priority.

If the port is VLAN aware and the frame is tagged, then the frame is classified to a QoS

class that is based on the PCP value in the tag as shown below. Otherwise the frame is

classified to the default QoS class.

PCP value: 0 1 2 3 4 5 6 7

QoS class: 1 0 2 3 4 5 6 7

If the port is VLAN aware, the frame is tagged and Tag Class is enabled, then the

frame is classified to a QoS class that is mapped from the PCP and DEI value in the tag.

Otherwise the frame is classified to the default QoS class.

The classified QoS class can be overruled by a QCL entry.

Note: If the default QoS class has been dynamically changed, then the actual default

QoS class is shown in parentheses after the configured default QoS class.

Common Server Configuration

Label Description

Timeout The Timeout, which can be set to a number between 3 and 3600 seconds, is the

maximum time to wait for a reply from a server. If the server does not reply within this time frame, we will consider it to be dead and continue with the next enabled server (if any). RADIUS servers are using the UDP protocol, which is unreliable by design. In order to cope with lost frames, the timeout interval is divided into 3 subintervals of equal length. If a reply is not received within the subinterval, the request is transmitted again. This algorithm causes the RADIUS server to be queried up to 3 times before it is considered to be dead.

Dead Time The Dead Time, which can be set to a number between 0 and 3600 seconds, 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 Dead Time to a value greater than 0 (zero) will enable this feature, but only if more than one server has been configured.

NA S (802.1x)

This page allows you to configure the IEEE 802.1X and MAC-based authentication system and port settings.

The IEEE 802.1X standard defines a port-based access control procedure that prevents unauthorized access to a network by requiring users to first submit credentials for authentication. One or more central servers, the backend servers, determine whether the user is allowed access to the network. These backend (RADIUS) servers are configured on the Authentication configuration page.

MAC-based authentication allows for authentication of more than one user on the same port, and doesn’t require the user to have special 802.1X software installed on his system. The switch uses the user’s MAC address to authenticate against the backend server. Intruders can create counterfeit MAC addresses, which makes MAC-based authentication less secure than 802.1X authentication.

Overview of 802.1X (Port-Based) Authentication

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 switch 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 MD5Challenge, 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 success or failure indication. Besides forwarding this decision to the supplicant, the switch uses it to open up or block traffic on the switch port connected to the supplicant.

Note: Suppose two backend servers are enabled and that the server timeout is configured to X seconds (using the Authentication 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.

Overview of MAC-Based Authentication

Unlike 802.1X, MAC-based authentication is not a standard, but merely a best-practices 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 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-xx-xx-xx”, that is, a dash (-) is used as separator between the lower-cased hexadecimal digits. The switch only supports the MD5Challenge 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 static entries into the MAC Table. 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 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 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, and only the MD5-Challenge method is supported.

The 802.1X and MAC-Based Authentication configuration consists of two sections, a system – and a port-wide

Label Description

Mode Indicates if 802.1X and MAC-based authentication is globally enabled or disabled on

the switch. If globally disabled, all ports are allowed forwarding of frames.

Reauthentication Enabled

If checked, 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. 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 Age Period below).

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.

EAPOL Timeout Determines the time for retransmission of Request Identity EAPOL frames.

Valid values are in the range 1 to 65535 seconds. This has no effect for MAC-based ports.

Age Period This setting applies to the following modes, i.e. modes using the Port Security

functionality to secure MAC addresses:

• 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. 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.

Hold Time This setting applies to the following modes, i.e. modes using the Port Security

functionality to secure MAC addresses:

• 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. 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.

Port The port number for which the configuration below applies.

Admin State

If NAS is globally enabled, this selection controls the por t’s authentication mode. The following modes are available:

Force Authorized

In this mode, the switch will send one EAPOL Success frame when the port link comes up, and any client on the por t will be allowed network access without authentication.

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.

Port-based 802.1X

In the 802.1X-world, the user is called the supplicant, the switch is the authenticator, and the RADIUS ser ver is the authentication server. The authenticator acts as the man-in-the-middle, forwarding requests and responses bet ween the supplicant and the authentication server. Frames sent between the supplic ant 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 R ADIUS ser ver are RADIUS packets. RADIUS packets also encapsulate EAP PDUs together with other attributes like the switch’s IP address, name, and the supplicant ’s por t number on the switch. EAP is ver y flexible, in that it allows for dif ferent authentication methods, like MD5-Challenge, PEAP, and TLS. The impor tant 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 t ype (EAPOL or RADIUS) and forwards it. When authentication is complete, the R ADIUS ser ver sends a special packet containing a success or failure indication. Besides forwarding this decision to the supplicant, the switch uses it to open up or block traf fic on the switch port connected to the supplicant. Note: Suppose two backend servers are enabled and that the server timeout is configured to X seconds (using the AA A configuration page), and suppose that the firs t ser ver in the lis t 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 ser ver will be contac ted 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. Single 802.1X In por t-based 802.1X authentication, once a supplicant is successfully authenticated on a port, the whole por t is opened for network traf fic. 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 E APOL 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 Securit y module is used to secure a supplicant’s MAC address once successfully authenticated. Multi 802.1X In por t-based 802.1X authentication, once a supplicant is successfully authenticated on a port, the whole por t is opened for network traf fic. 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 por t 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 des tination MAC address for EAPOL frames sent from the switch towards the supplic ant, 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 EAPOL Star t or EAPOL Response Identit y 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 supplicant s that can be attached to a por t can be limited using the Por t Security Limit Control functionality. MAC-based Auth. Unlike port-based 802.1X, MAC-based authentication is not a s tandard, but merely a bes t-practices 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 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 E AP exchange with the RADIUS server. The 6-byte MAC address is converted to a string on the following form “xx-x x-xx-xxxx-x x”, 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 R ADIUS ser ver sends a success or failure indication, which in turn causes the switch to open up or block traffic for that par ticular 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 connec ted to the same port (e.g. through a 3rd par ty 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 sof tware 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 suppor ted.
