Chapter 1 System Overview

OPCOM3105 is a compact SDH Multi Service Access Device that implement SDH 155M upstream at line side. It can be used as remote device of OPCOM3500E to connect with OPCOM3500E SDH tributary unit. The service side provides 3 paths 10/100M Ethernet with switching function and one independent Ethernet interface by EOS to fulfill accessing of Ethernet service and access 4 paths E1 to SDH. Expanding slot of the device can connect with E-SUBM series sub-module of Raisecom to provide users flexible solutions for service accessing. 1+1 path protection and multiplex section protection functions are available in this device. The network maintenance and management is realized by DCC in-band network management path of STM-1.

OPCOM3107 just makes some modification based on OPCOM3105. the modification including: add redundant power supply, change the E1 interfaces from 4 to 8 or 16, and delete expanding slot on OPCOM3105. in fact there are 8E1 or 16E1 and 4 Fast-Ethernet, 2 STM-1 optical interface and 2 DC/AC power supply on OPCOM3107. Thus the operations about E-SUBM series expanding cards mentioned in this manual are not available to OPCOM3107 devices.

Set Successfully.

Note: use the command mac-polling before show mac information. Otherwise the information may invalid or not correct. Or users can use the command search mac-address HHHH.HHHH.HHHH to search mac address information saved at local device, but users also need to execute mac-polling command to update local mac address table information.

7.4 QOS function configuration

Related commands of QOS function:


[no] qos Qos enable/disable

qos default-cos <0-7> Configure defaulted cos value for current switch port.

[no] qos trust cos Enable QOS based on cos byte section in tag message

qos map cos-queue cos0 cos1 cos2 cos3 cos4 cos5 cos6 cos7

Configure COS corresponding priority

show qos Show QOS relevant status

OPCOM3105 supports queuing attemper based on priority weighted average. The function can use cos byte section priority or use interface priority configuration. When priority function disable, use port priority configuration by default and every interface is of the same priority.

There are four different priorities in OPCOM3105 device. Users can use qos map cos-queue cos0 cos1 cos2 cos3 cos4 cos5 cos6 cos7 command to configure corresponding relation between cos value and priority.


20

Example:

OPCOM3105(config)# qos map cos-queue 1 2 3 4 1 2 3 4

Set Successfully.

[no] qos trust cos command can used in configuration of choosing cos value or port privilege. If configured trust cos, device will allot privilege according to cos value.

Example:

OPCOM3105(config)# qos trust cos

Set Successfully.

Note: Priority configuration by default is realized by port COS value configuration. To modify mapping relation from cos to priority will affect the port priority configuration directly.


21

Chapter 8 VLAN Configuration

This chapter mainly introduces configuration of vlan.

Related commands of vlan configuration:


[no] vlan <2-4094> Create vlan or enter static vlan mode, no command can be used to delete vlan.

state (active | suspend) Vlan working state.

switchport access vlan <2-4094> Configure port to access mode, assign vlan for the port.

switchport dot1q-tunnel vlan <2-4094>

Configure port to tunnel mode, assign vlan for the port.

switchport trunk allowed vlan list Configure port to trunk mode; assign vlan allowed by the port.

switchport hybrid allowed vlan list Configure port to hybrid mode; assign vlan allowed by the port.

switchport mode (access | dot1q-tunnel)

Configure port mode, without change port vlan id.

switchport vlan <2-4094> Configure port vlan id, without change port mode.

show vlan [<2-4094>] Show vlan configuration information.

OPCOM3105 supports vlan configuration management function based on 802.1Q recommendation. Only single tag type configuration is in support here. Since vlan resource of the device is limited, it supports 11 user configured vlan and 4 default vlan at one time. When vlan resources are used out, release the already existed vlan before configure new vlan.

The 4 default vlan are: vlan1 includes interface and defaulted vlan of every port. Defaulted vlan are always existed. If one port belongs to its defaulted vlan, it can not be deleted.

The 4 standard interface types are: access port, tunnel port, trunk port and hybrid port. Users can configure one port type and assign vlan for the port. If destination vlan is not existed, system creates a vlan to meet the configuration request. Configuration won’t be effective and lack of printing resource information will display if all vlan resources are exhausted.

Example:

OPCOM3105(config-eswif/0/2)# sw trunk allowed vlan 301-305

Set Successfully.

OPCOM3105(config-eswif/0/1)# sw trunk allowed vlan 401-409

Vlan resource exhausted !

Users can use vlan command to enter static vlan mode, if the vlan is not existed, system checks vlan resource and create the vlan or show resource exhausted.

OPCOM3105(config-vlan300)# vlan 301

OPCOM3105(config-vlan301)#


22

OPCOM3105(config-vlan300)# vlan 310

Vlan resource exhausted !

Use state command to modify vlan state for the vlan that is existed:

OPCOM3105(config-vlan302)# state suspend

Set Successfully.

Besides, users can modify port mode without change port belonged vlan (command switchport mode (access | dot1q-tunnel)), or modify port belonged vlan without change port mode (command switchport vlan <2-4094>).

Chapter 9 Network Topology


Overview Point-to-point topology Chain topology Ring topology

9.1 Overview

OPCOM3105 provides bi-direction aggregation interface and Ethernet and E1 tributary interface. It is flexible to build network topology for meeting complicated structure in client accessing, as the below figure shows.

9.2 Point-to-point topology

Network of point to point topology is used in inter-office relay and extend or used to replace the existed PDH. The networking is shown in the picture below:

TM TM

TM device can form point to point non-protection network, and double TMs can form a 1+1 path protection of STM-1 level. When configured as 1+1 protection mode, the two optical interfaces can protect each other to enhance service reliability.

9.3 Chain topology

Network of chain topology is suitable for communication network in chain topology and tributary networks in chain topology.

TM device and ADM device can form a non-protection chain topology network, and double optical interface TM device and ADM device can form 1+1 protection chain of STM-1 level.

When configured as 1+1 protection mode, service reliability will enhance.


24

9.4 Ring topology

Network of ring topology is suitable for distribution of network elements in ring topology. With the feature of line interfaces self closed, service can be transmitted bi-directionally (eastward and westward), so the network has high reliability and self-healing ability.

This topology can form a 2F SNC-P.

9.4.1 2F SNC-P The advantages of 2F SNC-P are high speed, flexibility and all level capacities. The switching depends on local environment and has nothing to do with the network topology, so 2F SNC-P is suitable for all kinds’ topologies, especially dynamic network.

The disadvantage of 2F SNC-P is that all the tributaries in the ring are all APS architectures, that is between any two points, there are two transmission lines transmitting the data bi-directionally, and every receiving node receives the data bi-directionally. So the total service flow is lower than the device capacity.

2F SNC-P is suitable for access network, relay network and long distance network, which are concentrated, low service flow.


25

Chapter 10 Typical Application

OPCOM3105 is typical applied as remote device of OPCOM3500E SDH tributary module to supply SDH access for Ethernet and E1 service.

27

Configure DCC interface IP on OPCOM3105-C:








The network management station gateway to configure at last is the direct connected OPCOM3105-A IP address 192.168.4.28. (this configuration asks for users guarantee there is no IP address of network segment 10 and 11 at the network station, otherwise the message that with destination IP address belong to these two network segments will not able to transmit to default gateway.)

Ping 192.168.5.28 and 192.168.6.28 must be successful on OPCOM3105-A after configuration successfully, and network management host can access 192.168.5.28 and 192.168.6.28 to realize management of other devices. If one path of network management has fault, the host can manage other devices by alternative router. Selection of router is automatically operated in accordance with devices rip.

Typical Point-to-Point network management path application as the below figure shows:

Configure DCC interface IP on OPCOM3105-A:









28

Configure DCC interface IP on OPCOM3105-B:








At last, configure default gateway for network station to be direct connected OPCOM3105-A IP 192.168.4.28 (this configuration asks for users guarantee there is no IP address of network segment 10 at the network station, otherwise the message that with destination IP address belong to the network segments 10 will not able to transmit to default gateway.).

Ping 192.168.10.28 must be successful on OPCOM3105-A after configuration successfully, and network management host can access 192.168.10.28 to realize management of other devices. If east optical port of network management has fault, the network management data will shift to western optical port of DCC2 by automation.
