1 INTRODUCTION
The Metrodata WCM5100 allows for the extension of an Ethernet Service over an SDH,
Wide Area Network Connection. The WCM5100 is a managed unit allowing for the
effective demarcation between LAN and WAN services. Management of the WCM5100 is
achieved using either Telnet/SSH or SNMP (V1/V2c) via either the LAN or WAN ports.
In cases where management is not required, or undesired, the WCM5100 can operate
standalone with simple configuration options provided using bit switches located on the
underside of the unit.
The Metrodata WCM5100 is a manageable multiport Ethernet Switch with an SDH uplink,
supporting automatic fallback when using dual SFP modules. The WCM5100 provides two
10/100/1000BaseT Auto Negotiating, Auto switching Ports as well as a single SFP port
supporting either 1000Base-X or 100Base-FX SFP modules. The WCM5100 operates as a
layer 2 bridge and as such may be used to extend a LAN segment over an SDH WAN link.
The WCM5100 has an internal LAN switch offering full wire-speed switching between
ports. The WCM5100 uses MAC address filtering to filter all local traffic and only forward
traffic destined for remote stations. Each of the WCM5100’s LAN ports support automatic
cross-over switching and will therefore connect directly to a Hub/Switch/Router or PC End
Station.
The WCM5100 has support for both tagged and untagged frames, with both VLAN C-Tag,
and Provider Bridge S-Tag (QinQ) modes supported.
The WCM5100 supports either IP DSCP, or IEEE802.1p based traffic prioritisation with
outgoing traffic being queued in one of four priority queues.
The WCM5100 supports link OAM, IEEE802.3ah and RSTP for loop prevention.
The WCM5100 performs GFP frame encapsulation and supports the VC-4 and VC-3 EoS (
Ethernet over Sonet ) modes. Internal packet buffers enable the WCM5100 to smooth out
bursty traffic and prevent packet loss as the higher layer protocols rate adapt to the SDH
capacity.

2.2 Base Label and Bit Switches
On the underside of the WCM5100 unit there are bit switches which may be used to
configure certain functions within the unit. The bit switches are used to configure the
default settings following a cold start.
2.2.1 WCM5100 Base Label
2.2.2 Bit Switches
The bit switches are used to configure the default settings following a cold start, either
from the console, or by powering on with switch 8 in the OFF position.
2.2.2.1 Bit switch 1, Boot Mode 0
This bit switch is used to determine whether the IP proxy management mode is enabled or
not. IP proxy mode utilises OAM to remotely manage a WCM5100 device.

2.3 Rackmounting
The WCM5100 is a standalone, desktop unit however it may be mounted in a standard 19
inch rack using the rack mounting kit, part number 80-05-256.
To mount the WCM5100 in the 19 inch rack mount adaptor first remove the two M3x12
screws and washers from the rear panel of the unit. Then align the WCM5100 rear panel
with the mounting bracket, and secure the unit to the adaptor using the previously
removed screws.
When rack mounting, please ensure that the bit switches on the underside are correctly
configured prior to mounting the units in the rack.

3 WCM5100 APPLICATIONS
3.1 WCM5100 Normal Mode
In this application, the WCM5100 is operating with Traffic Isolation Disabled. In this mode,
the WCM5100 acts as a simple, layer 2, 5 port switch with packetsswitched based on MAC
address alone. The WCM5100 supports both local and remote switching, and forwarding
over the WAN trunk.
Management traffic is not isolated from the through data traffic, and both units may be
managed from any port.
3.2 WCM5100 VLAN Trunk Mode
In this application, WCM-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. WCM-A is
operating with VLAN support enabled but all ports defined as Trunks. A VLAN ID is
allocated to the Manager and thus management traffic is isolated from the user traffic and
the management VLAN, in this case 101, can be used to manage the WCM’s. WCM1100-
B is configured with VLAN support enabled but each port is configured as an access port
and isolated to a single VLAN.
Trunk ports expect packets to be tagged, whilst access ports expect untagged packets and
will add tag and priority to incoming packets.

3.3 VLAN Mode
In this mode, both WCM units have VLAN support enabled, and all ports are defined as
access ports VLAN 101 is used as the management VLAN and in unit WCM-A the VLAN
group 101 includes the LAN Port 1, the Manager and the SDH WAN port. At the remote
end, The SFP port is disabled to prevent customer access to the WCM manager.
3.4 S-Tag Mode
In this mode, the WCM 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.

4 QUICK START CONFIGURATION
The following guide gives a simple, quick start introduction to configuring the WCM5100
for Normal Mode operation as shown in section 2.1
4.1 Cold Start the Unit
When a WCM5100 is shipped from the factory it will be in the default condition, however
with previously used equipment this may not be the case. To return the unit to the default
state will require a power cycle and configuration of the bit switches.
The underside of the unit has a set of accessible bit switches and a label, as shown below
for the two products:
Ensure all other bit switches are in the desired default positions.
To cold start the unit, first set bit switch 8 (Cold Start) to the OFF (Return to Default
Settings) position. Power up the WCM5100, wait for the Status LED to come on in any
state, and then power down. To return to normal mode, return bit switch 8 to the ON
(Normal Operation) position.
4.2 Access the WCM
Initial access to the WCM5100 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 D-
Type is configured as a DCE port with standard pin out as shown below:
