The LHM1000 is a 4-port Gigabit Ethernet switch with VLAN support. Two ports are presented on standard RJ45 10/100/1000Base-T interfaces supporting auto-negotiation and auto MDI/MDI-X sensing. One port is presented as a standard SFP socket, allowing for a 100M or Gigabit fibre interface or third copper port.
The fourth port employs an HDLC encapsulation system to pass Ethernet packets over a Wide Area Network via a HSSI DTE interface. Data rates up to 52Mbps are supported. The unit can source a 51.84MHz clock if required.
VLAN support allows traffic to be partitioned and routed selectively between ports. Pushing/popping of customer (802.1Q) or provider/Q-in-Q (802.1ad) tags is also possible and can be managed flexibly to suite a wide range of applications.
The unit supports a Link Loss Forwarding mechanism, allowing a fault condition at one port (typically the WAN) to be reflected at one or more other ports as an outgoing link-down state. 802.3ah 'Link OAM' protocol can be used to provide extra confidence in the port connections.
Jumbo frames (up to 10240 bytes) can be handled. An ingress rate-limiting mechanism may be applied to any port. The unit contains 4 internal priority queues. A range of priority management tools are available to optimise their use, including DSCP-to-PCP mapping, PCP-to-queue mapping and VLAN-based PCP overriding.
A menu-based user interface, accessed via local terminal port, Telnet or SSHv2, allows unit configuration and viewing of status and performance data. IP-based management packets can enter the unit via any port. These may be partitioned from other traffic using VLANs if desired. The user interface is password protected, with the option of TACACS+ for external secure user authentication. Management of the unit is also possible via the SNMP protocol, with a range of standard and proprietary MIBs supported.
Metrodata's layer 3 proxy system allows for zero-configuration installation of units and remote commissioning. The unit offers a range of loopback, BERT and cable test functions to aid fault diagnosis, plus comprehensive performance data logging.
The LHM1000 is ordered without a SFP fitted, although customers can subsequently change their interface type. Please contact Metrodata for price and availability of SFP modules including long haul, 1550nm, bi-directional and CWDM.
The LHM1000 is available in a choice of 100-250 VAC or -48 VDC integrated power supplies.
The LHM1000 can easily be rack mounted in either a 1U two unit rack mount kit , a 6U eighteen unit rack mount kit.
The LHM1000 is part of a wide range of LAN extension products from Metrodata.
This application shows an LHM1000 unit being used as the Ethernet demarcation device to deliver a Carrier Ethernet service from an MPLS core network. A wide choice of Ethernet connectivity is available for the user via the 10/100/1000baseT and SFP fibre ports. OAM support means that the LHM1000 can be remotely managed by the central network management system using standards based OAM packets.
This application shows how a pair of LHM1000 units can be used to offer Ethernet service demarcation and LAN Extension functionality either over a HSSI Serial circuit.
