1 INTRODUCTION
This manual details the basic information required to configure and operate the Metrodata
WCM1400, WCM1800 and WCM1820 family of Products. The product range allows the
extension of Ethernet Services over multiple, bonded E1 Wide Area Network Connections.
The WCM1400 provides 4 E1 ports, giving an uplink capacity of approximately 8Mbps.
The WCM1800 provides 8 E1 ports giving a maximum uplink bandwidth of approximately
16 Mbps, and the WCM1820 provides 16 E1 ports giving a maximum uplink bandwidth of
32Mbps.
Throughout the document WCM1800 will be used, however this manual equally applies to
the WCM1400 and WCM1820.
The WCM1800 performs GFP frame encapsulation and uses Virtual Concatenation
(VCAT) to bond multiple E1 circuits together according to ITU-G.7043 with ITU-G.7042
LCAS to allow for the addition or removal of circuits. Internal packet buffers enable the
WCM1800 to smooth out bursty traffic and prevent packet loss as the higher layer
protocols rate adapt to the bonded E1 capacity. The E1 ports operate in framed mode
using G.704 with CRC-4 multi frame enabled. The WCM1800 range offers upto 4 VCAT
groups (VCG) allowing for upto 4 remote devices to be connected.
The WCM1800 is a managed unit allowing for the effective demarcation between LAN and
WAN services. Management of the WCM1800 is achieved using either Telnet or SNMP
via either the LAN or WAN ports.
The Metrodata WCM1800 is a manageable multiport Ethernet Switch with a multiple,
bonded E1 uplink. The WCM1800 provides two 10/100/1000BaseT Auto Negotiating,
Auto-Switching RJ45 Ports as well as a single SFP port supporting either 1000Base-X or
100Base-FX SFP modules. The WCM1800 operates as a layer 2 bridge and as such may
be used to extend a LAN segment over a WAN link.
The WCM1800 has an internal LAN switch offering full wire-speed switching between
ports. The WCM1800 uses MAC address filtering to filter all local traffic and only forward
traffic destined for remote stations. Each of the WCM1800’s LAN ports support automatic
cross-over switching and will therefore connect directly to a Hub/Switch/Router or PC End
Station.
The WCM1800 has support for both tagged and untagged frames, with both VLAN C-Tag,
and Provider Bridge S-Tag (QinQ) modes supported.

Quick Start Guide
2 WCM1800 Applications
2.1 WCM1800 Normal Mode
In this application, the WCM1800 is operating with Traffic Isolation Disabled. In this mode,
the WCM1800 acts as a simple, layer 2, 5 port switch with packets being switched based
on MAC address alone. The WCM1800 supports both local and remote switching.
Management traffic is not isolated from the through data traffic, and both units may be
managed from any port.
The WAN link comprises 8 E1 circuits running E1 G.704 CRC-4 framing with GFP packet
encapsulation and VCAT/LCAS to give a combined trunk bandwidth of 15.87Mbps for
payload. In this mode, the untagged frames are directed to VCG1.
2.2 WCM1800 VLAN Trunk Mode
76-02-087 Rev D
Page 11
METRODATA LTD WCM1400/WCM1800/WCM1820
11 of 61
Quick Start Guide
In this application, WCM1800-A is connected to a VLAN enabled LAN switch. The LAN
switch is configured as a VLAN trunk and all packets are tagged with VLAN Tags.
WCM1800-A is operating with VLAN support disabled, but with a VLAN ID allocated to the
Manager. In this way, the management VLAN, in this case 101, can be used to manage
the WCM1800. WCM1800-B is configured with VLAN support enabled and thus each port
is isolated to a single VLAN.
2.3 WCM1800 VLAN Access Mode
In this mode, both WCM1800 units have VLAN support enabled. VLAN 101 is used as the
management VLAN and in unit WCM1800-A the VLAN group 101 includes the LAN Port 1,
the Manager and the E1 port. At the remote end, Port 1 is disabled to prevent customer
access to the WCM1800 manager.
2.4 WCM1800 S-Tag Mode
In this mode, the WCM1800 adds a, port based, S-TAG to all incoming traffic. Where
customer traffic is already VLAN tagged, this leads to double tagging or ‘QinQ’ operation.
The use of the S-TAG enables the carrier to isolate customer traffic. Carrier management
traffic is carried with a separate S-Tag giving management access to both units, and on
the customer site the external management access is disabled.

Quick Start Guide
2.5 Point to Multi-Point
12 of 61
In this application, the traffic is transported to remote destinations based on the incoming
VLAN C-Tag. To support the point to multipoint management, the IP Proxy mode is used
with device A acting as the server and B/C acting as clients.
In this application, WCM1800-A is operating with VLAN mode enabled and is operating
LAN Port 2 in VLAN Trunk Mode. Incoming packets must be tagged and are switched
based on the incoming tag. Individual VLAD ID’s or ranges may be allocated to each
VCG. In this case, VLAN 101 and 102 are allocated to VCG1 serving remote device B,
whilst VLAN 103, 104 are allocated to VCG2 serving remote device C.
The remote devices, B and C are both operated in VLAN mode but with the LAN ports in
access mode stripping the tags from egress packets and tagging packets on ingress.

3 Theory of Operation
3.1 Frame Encapsulation
The WCM1800 uses the Generic Framing Procedure (GFP) to encapsulate the Ethernet
frames for transmission over the WAN link(s). GFP is a byte aligned procedure and hence
is suitable for use with multi link bonding. GFP does not use bit stuffing as with HDLC and
is therefore a deterministic protocol. The diagram below compares HDLC and GFP for
encapsulation of an Ethernet Frame
The native Ethernet frame is encapsulated under GFP as shown.
The GFP core header is four bytes long and is used for packet delineation. To decouple
the line rate from the packet rate, idle frames consisting of the core header only are sent.
The GFP payload header provides information about the payload type and also whether
the payload includes an FCS. The GFP payload header uses 4 bytes.
The GFP payload area contains the Ethernet Frame payload. Since the receiver uses the
core header pattern to delineate packets, scrambling the payload helps to prevent aliasing
of the header and improves reliability.
76-02-087 Rev D
Page 14
METRODATA LTD WCM1400/WCM1800/WCM1820
14 of 61
Quick Start Guide
The GFP frame contains an optional FCS, Frame Check Sequence. Packets received
with an FCS error will be discarded. Since the GFP frame is protected from bit errors by
the GFP payload FCS, the MAC FCS may be stripped and recalculated at the remote end
to save bandwidth.
3.2 Virtual Concatenation and LCAS
Virtual Concatenation (VCAT) is a method of bonding multiple E1 circuits together to form
a single connection with increased capacity. LCAS, Link Capacity Adjustment Procedure,
is a protocol which will enable a failed link to be removed from the VCAT group to allow
traffic to pass over a reduced capacity link.
VCAT inserts a single overhead byte immediately following FAS pattern in the first frame
of a CRC-4 multiframe. The VCAT control byte is shown below:
The VCAT control byte forms a 16 frame multi frame to pass all the required information.
Each link is given a sequence number, and a status bit (MST). Through the use of the
VCAT control word, the multiple links in the group can be aligned with upto 250ms of delay
variation compensated for.
LCAS operates using the VCAT control word and uses the MST status bits and
CTRL/LCAS control to monitor the status of all members of the group, and remove any
that fail or add in any new links in a hitless manner.

4 Quick Start Configuration
The following guide gives a simple, quick start introduction to configuring the WCM1800
for Normal Mode operation as shown in section 2.1
4.1 Access the WCM1800
Initial access to the WCM1800 is made using the Terminal Port on the rear panel of the
unit. The Terminal port defaults to 19200baud, 8bit, No Parity 1 Stop Bit. The 9 Way DType is configured as a DCE port with standard pinout.
4.2 Logging onto WCM1800
The initial access to the WCM1800 must use a terminal connected to the terminal port.
The WCM1800 has a password protected, menu driven user interface. When a
management session is connected to the WCM1800, the welcome banner will be
displayed as shown:
Metrodata WCM1800: Local connection to “”
Password (‘view’ to view only ) :
At the prompt, enter the password to gain access to the WCM1800.
The default password is product specific as below:
WCM1400: default password “wcm1400”
WCM1800: default password “wcm1800”
WCM1820: default password “wcm1820”
For security, the password is obscured with an asterisk (*) being displayed for each
character typed. An incorrect password will lead to the welcome banner being
redisplayed. A correct password will lead onto the main set up menu as shown below:
Throughout this manual, the Telnet VT100 emulation user screens will be displayed.

Quick Start Guide
4.2.1 User Interface Navigation
16 of 61
The WCM1800 user interface is a simple, menu based interface. Each selectable item
may be selected by typing the first capital of the option, e.g. for “Data port set-up” type
<D>1 or <d>. Sometimes, where multiple items have the same starting letter the selection
capital will not be the first letter, e.g. “alarm eXtension” which is selected with <X> or <x>.
On the right side of the display is a list of what is below each item. This could be:
<menu> This indicates a sub-menu will be entered
<display> This indicates an information screen will be displayed. This may be
status or statistics.
Additional keys may be used to navigate the menu system:
<ESC> This will exit the current menu, or log out from the main set up menu.
<SPACE> This will toggle through a list of selectable options
<ENTER> This will select an item
1
Encapsulating an item within < > indicates a key press is required, for example <D>
means type D.

5.1.1 Setting the Time and Date
The WCM1800 does not provide a non volatile Real Time Clock, instead it uses NTP to set
the date and time following power up. In applications where NTP is not available, the
WCM1800 defaults to providing a simple uptime display.
To configure the NTP parameters, select the “Time and date” menu from the “System”
menu. The menu is as below:
If NTP is available, then the following parameters need to be set,
Time Zone +/-12 Since NTP uses GMT, time zone adjustment allows the
correct time to be configured wherever the units are
deployed globally.

5.1.6 Warm Start
A warm Start will force the WCM1800 to restart and reload the configuration from the
EEPROM. Note, any changes to configuration that have not been saved to the EEPROM
will be lost.
When a user issues a warm start request, the WCM1800 will indicate that a warm start is
in progress and then close the connection.
5.1.7 Cold Start
Cold Start will return the WCM1800 to the factory default condition and as defined by the
bit switch settings.
Note, that a cold start will erase IP addresses and Routing Table entries and it is therefore
highly likely that remote access will be lost following a cold start.
For this reason a cold start request must be confirmed before it is actioned.

5.2.1 LAN Port
The WCM1800 has two external copper LAN ports which by default operate in
10/100/1000BaseT auto negotiating, auto crossover mode. The LAN ports are presented
on RJ45 connectors and support access to the other external local LAN ports, the
management processor or the WAN forwarding port.
The LAN port menu allows for configuration of the LAN port parameters and VLAN settings
5.2.1.1 State
The port state is the administrative state of this port. The state may be up or down. When
‘UP’, the port is enabled and will generate a Major Alarm if the link is physically down.
When in the ‘DOWN’ state, the port is disabled.
5.2.1.2 Link Status
The Link Status is a display of the current link status. If the link is up, the link status will
show UP and vice versa. Only when the link status is up are the operating parameters
valid when in auto negotiating mode.
5.2.1.3 Auto Negotiation
The port may be configured to automatically determine the optimal operating parameters
for link speed and duplex. Alternatively, it may be disabled to enable configuration of fixed
operating parameters.
76-02-087 Rev D

Quick Start Guide
Note, the Auto Negotiating algorithm works optimally with a link partner that also supports
auto negotiation. For operation where one end of a link uses fixed configuration and does
not negotiate, it must be noted that only Speed, 10 or 100M, can be determined, the auto
negotiating node will fall back to use half duplex. 1000M operation requires auto
negotiation.
5.2.1.4 Speed
When in auto negotiating mode, the speed displayed is the highest that will be advertised
to the link partner. In non auto negotiating mode, the speed is manually set by the user.
5.2.1.5 Duplex
When in auto negotiating mode, the duplex displayed is the highest that will be advertised
to the link partner. In non auto negotiating mode, the duplex is manually set by the user.
5.2.1.6 Negotiated
this item displays the actual operating parameters of the link following auto negotiation and
may take the values:
1000/FD 1000Mbps, Full Duplex
100/FD 100Mbps, Full Duplex
100/HD 100Mbps, Half Duplex
10/FD 10Mbps, Full Duplex
10/HD 10Mbps, Half Duplex
5.2.1.7 MDI/MDIX
By default, the ports support automatic crossover configuration when required. The port
may be configured as follows:
AUTO Auto Sense and configure
MDI Present MDI interface, direct connection to switch
MDIX Present MDIX Interface, direct connection to PC

Quick Start Guide
5.2.1.8.1 Traffic Type
In order to provide port based traffic isolation this parameter defines what type of traffic
passes over this interface. The options are as below
User + Mgmt This port carries user and management traffic. Management frames
are switched to the processor, whilst user frames are switched to the
WAN port.
User only This port only carries user traffic and ALL frames are switched to the
WAN port with no access to the management processor
Mgmt only This port only carries Management Traffic and all frames are
forwarded to the management processor with no frames forwarded to
the WAN port.
5.2.1.8.2 Port Type
If the traffic isolation mode is set to VLAN mode, then the LAN port may be defined as
either an Access or Trunk port.
An Access port expects untagged frames to ingress, and will strip tags for egress frames.
The port will add the configured VLAN ID.
A Trunk port expects ingress and egress packets to be tagged.
5.2.1.8.3 VLAN/S-Tag ID
If the Traffic Isolation mode is set to VLAN then the LAN port may be assigned to a VLAN.
and all frames ingressing this port will have a VLAN Tag added. This configuration item
defines the VLAN ID which will be added and may be in the range (1 to 4095 ). One or
more ports may be assigned to the same VLAN and packets will then only switch between
those ports and the WAN interface.
In VLAN mode, packets are expected to ingress the LAN ports untagged, and will have
any tags stripped before egress.
If the traffic isolation mode is set to QinQ, then the defined S-TAG will be added to all
incoming frames. If ingress traffic is already C-Tagged then the S-TAG will be added as
the outer most tag giving QinQ operation.

When the traffic isolation mode is VLAN, this is the priority value that is added with the
VLAN ID during ingress. In QinQ mode, untagged packets are given this default priority,
whilst tagged packets promote the C-TAG priority to the S-TAG priority.
5.2.1.9 OAM
The LAN port supports IEEE 802.3 clause 57 link OAM. The LAN port may operate in
Active, Passive or have OAM functions disabled.
In Active mode, the port will transmit a status request once a second to solicit information
from the attached peer device.
In Passive mode, the port will wait for a status request from the active peer and will
respond with its local status.
In disabled mode, OAM will be disabled.
When OAM is enabled, the port OAM status may be displayed
when the peer device is identified as a member of the Metrodata MetroConnect product
range, proprietary enterprise extensions are used to extract further useful information
about the remote unit status.

In server mode, the transfer is initiated from an external client. If the file downloaded
matches that configured for Software or Config then they will be used to upgrade the
software or configuration.
To use TFTP, the IP address of the remote server must be entered.
For security reasons, it is recommended to change the default settings for software and
config file names to prevent unauthorised updates.
To initiate a TFTP transfer from a windows PC, select a DOS window and then type the
command
tftp –i “WCM1800 IP Address” put “Source Filename” “Software File Name”
eg
tftp –i 192.168.0.1 put wcm1800.80 software
Which will load a file named “wcm1800.80” onto the WCM1800 with IP address
192.168.0.1 and load as a file called “software”
