Overview
Introduction
The ComNet CWGE28FX4TX24MS is a managed redundant ring Ethernet switch with
24x10/100/1000Base-(TX) ports and 4x1000Base-X SFP ports. The Ethernet Redundancy protocol,
C-Ring (Gigabit model recovery time < 30ms over 250 units of connection) and MSTP/RSTP/
STP (IEEE 802.1s/w/D) can protect your applications from network interruptions or temporary
malfunctions with its fast recovery technology.
ComNet’s Ethernet switches provide advanced IP-based bandwidth management which can limit
the maximum bandwidth for each IP device. The User can configure IP cameras and Network
Video Recorders with more bandwidth and limit other device’s bandwidth.
ComNet’s Ethernet switches also support application-based QoS. Application-based QoS can set
the highest priority for data stream according to TCP/UDP port number. The ComNet special IP
police function can permit only allowed IP address with MAC address to access the networking.
Unintended access is eliminated, as a user cannot access the IP surveillance network without
permission. Moreover, the ComNet CWGE28FX4TX24MS switch provides advanced DoS/DDoS
auto prevention. If an IP flow rises quickly, the CWGE28FX4TX24MS switch will lock the source IP
address for a certain time to prevent the attack. It is hardware-based prevention so it can prevent
DDOS attack immediately and completely. And all functions of the CWGE28FX4TX24MS can also
be centrally managed conveniently by eConsole, the Web-based interface, Telnet and console
(CLI) configuration. Therefore, the switch is one of the most reliable choices for highly managed
and Gigabit Fiber Optic Ethernet applications.

Rx ErrorsThe 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-OutsEach 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 incremented.

Redundancy
C-Ring
C-Ring is the most powerful Redundant Ring 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 Ring
topology: C-Ring, Coupling Ring and Dual Homing.
Ring interface
The following table describes the labels in this screen.
LabelDescription
Redundant RingMark to enable C-Ring.
Ring MasterThere should be one and only one Ring Master in a ring. However if there are two or more
switches that 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 PortThe primary port, when this switch is Ring Master.
2nd Ring PortThe backup port, when this switch is Ring Master.
Coupling RingMark 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 PortLink to Coupling Port of the switch in another ring. Coupling Ring need four switch to build
an active and a backup link.
Set a port as coupling port. The coupled four ports of four switches will be run at active/
backup mode.
Dual HomingMark to enable Dual Homing. By selecting Dual Homing mode, C-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 C-Ring to the normal switches in RSTP mode.
Save Save the configurations.
Note: We don’t suggest you to set one switch as a Ring Master and a Coupling Ring at the same
time due to heavy load.

Legacy Ring
Legacy ring provides support for the switch to be used in an existing ring of ComNet X-Ring
enabled switches.
X-Ring provides a faster redundant recovery than Spanning Tree topology. The action is similar to
STP or RSTP, but the algorithms between them are not the same. In the X-Ring topology, every switch
should be enabled with X-Ring or Legacy Ring function and two ports should be assigned as the
member ports in the ring. Only one switch in the X-Ring group would be set as the master switch
that one of its two member ports would be blocked, called backup port, and another port is called
working port. Other switches in the X-Ring group are called working switches and their two member
ports are called working ports. When the failure of network connection occurs, the backup port of the
master switch (Ring Master) will automatically become a working port to recover from the failure.
The switch supports the function and interface for setting the switch as the ring master or not. The ring
master can negotiate and place command to other switches in the X-Ring group. If there are 2 or more
switches in master mode, the software will select the switch with lowest MAC address number as the
ring master. The X-Ring master ring mode can be enabled by setting the Legacy Ring configuration
interface. Also, the user can identify whether the switch is the ring master by checking the R.M. LED
indicator on the front panel of the switch.

LabelDescription
PortThe switch port number of the logical STP port.
STP EnabledControls whether STP is enabled on this switch port.
Path CostControls the path cost incurred by the port. The Auto setting will set the path cost as
appropriate by the physical link speed, using the 802.1D recommended values. Using
the Specific setting, a user-defined value can be entered. The path cost is used when
establishing the active topology of the network. Lower path cost ports are chosen as
forwarding ports in favor of higher path cost ports. Valid values are in the range 1 to
200000000.
PriorityControls the port priority. This can be used to control priority of ports having identical
port cost. (See above).
OpenEdge
(state flag)
Operational flag describing whether the port is connecting directly to edge devices.
(No Bridges attached). Transitioning to the forwarding state is faster for edge ports
(having operEdge true) than for other ports.
AdminEdgeControls whether the operEdge flag should start as being set or cleared. (The initial
operEdge state when a port is initialized).
AutoEdgeControls whether the bridge should enable automatic edge detection on the bridge
port. This allows operEdge to be derived from whether BPDU’s are received on the
port or not.
Restricted RoleIf enabled, causes the port not to be selected as Root Port for the CIST or any MSTI,
even if it has the best spanning tree priority vector. Such a port will be selected as an
Alternate Port after the Root Port has been selected. If set, it can cause lack of spanning
tree connectivity. It can be set by a network administrator to prevent bridges external
to a core region of the network influencing the spanning tree active topology, possibly
because those bridges are not under the full control of the administrator. This feature is
also know as Root Guard.
Restricted TCNIf enabled, causes the port not to propagate received topology change notifications
and topology changes to other ports. If set it can cause temporary loss of connectivity
after changes in a spanning trees active topology as a result of persistent incorrectly
learned station location information. It is set by a network administrator to prevent
bridges external to a core region of the network, causing address flushing in
that region, possibly because those bridges are not under the full control of the
administrator or is the physical link state for the attached LANs transitions frequently.
Point2PointControls whether the port connects to a point-to-point LAN rather than a shared
medium. This can be automatically determined, or forced either true or false. Transition
to the forwarding state is faster for point-to-point LANs than for shared media.

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.

Port QoS
This page allows you to configure QoS settings for each port.
Frames can be classified by 4 different QoS classes: Low, Normal, Medium, and High.
The classification is controlled by a QCL that is assigned to each port.
A QCL consists of an ordered list of up to 12 QCEs.
Each QCE can be used to classify certain frames to a specific QoS class.
This classification can be based on parameters such as VLAN ID, UDP/TCP port, IPv4/IPv6 DSCP or
Tag Priority.
Frames not matching any of the QCEs are classified to the default QoS class for the port.

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, System
Configuration and Port Configuration.

LabelDescription
System Configuration
ModeIndicates 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.
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).
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.
EAP
Timeout
Determines the time the switch shall wait for the supplicant response before retransmitting a
packet. Valid values are in the range 1 to 255 seconds. This has no effect for MAC-based ports.
Age Period This setting applies to ports running MAC-based authentication, only.
Suppose a client is connected to a 3rd party switch or hub, which in turn is connected to a port
on this switch that runs MAC-based authentication, and suppose the client gets successfully
authenticated. Now assume that the client powers down his PC. What should make the switch
forget about the authenticated client? Reauthentication will not solve this problem, since this
doesn’t require the client to be present, as discussed under Reauthentication Enabled above. The
solution is aging of authenticated clients. The Age Period, which can be set to a number between
10 and 1000000 seconds, works like this: A timer is started when the client gets authenticated.
After half the age period, the switch starts looking for frames sent by the client. If another half age
period elapses and no frames are seen, the client is considered removed from the system, and it
will have to authenticate again the next time a frame is seen from it. If, on the other hand, the client
transmits a frame before the second half of the age period expires, the switch will consider the
client alive, and leave it authenticated. Therefore, an age period of T will require the client to send
frames more frequent than T/2 for him to stay authenticated.
Hold TimeThis setting applies to ports running MAC-based authentication, only.
If the RADIUS server denies a client access, or a RADIUS server request times out (according to
the timeout specified on the Authentication configuration page), the client is put on hold in the
unauthorized state. In this state, frames from the client will not cause the switch to attempt to
re-authenticate the client. The Hold Time, which can be set to a number between 10 and 1000000
seconds, determines the time after an EAP Failure indication or RADIUS timeout that a client is not
allowed access.

LabelDescription
System Configuration
PortThe port number for which the configuration below applies.
Admin
State
Sets the authentication mode to one of the following options (only used when 802.1X or
MAC-based authentication is globally enabled):
Auto: Requires an 802.1X-aware client (supplicant) to be authorized by the authentication
server. Clients that are not 802.1X-aware will be denied access.
Authorized: Forces the port to grant access to all clients, 802.1X-aware or not. The switch
transmits an EAPOL Success frame when the port links up.
Unauthorized: Forces the port to deny access to all clients, 802.1X-aware or not. The switch
transmits an EAPOL Failure frame when the port links up.
MAC-Based: Enables MAC-based authentication on the port. The switch does not transmit or
accept EAPOL frames on the port. Flooded frames and broadcast traffic will be transmitted
on the port, whether or not clients are authenticated on the port, whereas unicast traffic
against an unsuccessfully authenticated client will be dropped. Clients that are not yet
successfully authenticated will not be allowed to transmit frames of any kind.
Port StateThe current state of the port. It can undertake one of the following values:
Disabled: 802.1X and MAC-based authentication is globally disabled.
Link Down: 802.1X or MAC-based authentication is enabled, but there is no link on the port.
Authorized: The port is authorized. This is the case when 802.1X authentication is enabled,
the port has link, and the Admin State is “Auto” and the supplicant is authenticated or the
Admin State is “Authorized”.
Unauthorized: The port is unauthorized. This is the case when 802.1X authentication is
enabled, the port has link, and the Admin State is “Auto”, but the supplicant is not (yet)
authenticated or the Admin State is “Unauthorized”.
X Auth/Y Unauth: X clients are currently authorized and Y are unauthorized. This state is
shown when 802.1X and MAC-based authentication is globally enabled and the Admin State
is set to “MAC-Based”.
Max
Clients
This setting applies to ports running MAC-based authentication, only.
The maximum number of clients allowed on a given port can be configured through the listbox and edit-control for this setting. Choosing the value “All” from the list-box allows the port
to consume up to 48 client state-machines. Choosing the value “Specific” from the list-box
opens up for entering a specific number of maximum clients on the port (1 to 48).
The switch is “born” with a pool of state-machines, from which all ports draw whenever a new
client is seen on the port. When a given port’s maximum is reached (both authorized and
unauthorized clients count), further new clients are disallowed access. 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 state-machines.

Clicking these buttons will not cause settings changed on the page to take effect.
Reauthenticate: Schedules a reauthentication to whenever the quiet-period of the port runs out
(port-based authentication). For MAC-based authentication, reauthentication will be attempted
immediately.
The button only has effect for successfully authenticated ports/clients and will not cause the port/
client to get temporarily unauthorized.
Reinitialize: Forces a reinitialization of the port/clients and thereby a re-authentication immediately.
The port/clients will transfer to the unauthorized state while the reauthentication is ongoing.

shows backend server counters for the currently selected client, or dashes if no client is
selected or available. A client can be selected from the list of authorized/unauthorized
clients below the two counter tables.
There are slight differences in the interpretation of the counters between port- and
MAC-based authentications.
