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, appoint vlan for the port

switchport dot1q-tunnel vlan

<2-4094>

Configure port to tunnel mode, appoint vlan for the port

switchport trunk allowed vlan list Configure port to trunk mode, appoint vlan allowed by the port

switchport hybrid allowed vlan list Configure port to hybrid mode, appoint 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 default vlan of every port. Default vlan always exists. If one port belongs to its default 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 appoint vlan for the port. If destination vlan is not existed, system creates a vlan to meet the configuration reques. Configuration won’t be effective and lack of 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:

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 Clock Configuration

9.1 Related commands

Command Description

Config Enter global configuration mode.

device clock ssm (disable|standard|extend)

Configure SSM mode.

disable: SSM function disable, switch of clock just depends on alarm and priority and alarm of clock source; standard: enable SSM described in ITU-T G.781; extend: extending standard SSM by enabling clock ID, enhance the capacity of avoiding clock loop.

device clock local priority <1-5> [quality (prc|ssua|ssub|sets|dnu|received)] Or device clock sdh-port <1-2> priority <1-5> [quality (prc|ssua|ssub|sec|dnu|received)] Or device clock e1 <1-4> priority <1-5> [quality (prc|ssua|ssub|sec|dnu|received)]

Configure priority of clock source and quality level set in advance. Set quality level to be received, which indicates the quality level not set in advance but scavenge from the real-time received singal from clock source. Generally speaking, local must set quality level in advance; other clock source can set quality level or not according to the condition if input signal takes along with SSM information.。

device clock local id <0-15> Or device clock sdh-port <1-2> id <0-15> Or device clock e1 <1-4> id <0-15>

Configure clock source ID. This configuraiton is meaningless except under extend SSM mode. In extend SSM mode, clock source to synchronize with NE in synchronous network should all set with ID.

show device clock Show clock information.

9.2 Configure synchronous chain network

9.2.1 Chain topology configuration Chain network topology is one the simplest synchronous network topology in common use. Suppose a chain network topology with 4 NE as below figure shows:

Single BITS chain synchronous network topology

Eastbound SDH port of NE1 access to OPCOM3500E to aggregate services; eastbound SDH port of


24

NE2 connects with westbound port of adjacent device.

In normal running, the whole network synchronizes with device clock of OPCOM3500E; if OPCOM3500E clock is invalid, the whole network synchronizes with local clock of NE1. If fiber among NE is broken, synchronous network is cut off to be two chain sub-nets by the broken point of fiber and the two sub-nets run in pseudo synchronization mode.

Users should enable standard SSM protocol in whole network in this topology mode. Configuration of NE clock as below table shows:

NE1, NE2:

Priority Clock source Quality level Clock ID

1 Eastbound line clock source Scavenge by automation 0

2 Local crystal run SEC 0

9.3 Configure ring synchronous network

9.3.1 Single BITS ring configuration Single BITS chain topology is also a common synchronous network topology.

Suppose a chain network topology with 4 NE as below figure:

Single BITS ring synchronous network topology

External clock of NE1 input port accesses output of main BITS, westbound SDH port of NE2, NE3 and NE4 connect with eastbound port of adjacent device.

In normal running, the whole network synchronizes with main BITS clock; if BITS is invalid, the whole network synchronizes with local clock of NE1. If fiber among NE is broken, synchronous network is cut off to be two chain sub-nets by the broken point of fiber and the two sub-nets run as 9.2.1 showed mode.


25

Users should enable standard SSM protocol in whole network in this topology mode. Configuration of NE clock as below table shows:

NE1:


1 External clock source Scavenge by automation 0


NE2, NE3, NE4:



2 Westbound line clock source Scavenge by automation 0


9.3.2 Dual BITS ring configuration Dual BITS ring network topology adds one standby BITS comparing with single BITS network. The clock protection capability is greatly improved.

Suppose a ring network topology with 4 NE as figure below shows:

Dual BITS ring synchronous network topology

External clock of NE1 input port accesses output of main BITS, westbound SDH port of other NE connect with eastbound port of adjacent device. External clock input port of NE4 accesses output of standby BITS.


26

In normal running, the whole network synchronizes with main BITS clock; if BITS is invalid, the whole network synchronizes with standby BITS clock; if standby BITS is invalid, the whole network synchronizes with lock clock of NE1. If fiber among NE is broken, synchronous network is cut off to be two chain sub-nets by the broken point of fiber and the two sub-nets run as 9.2.1 showed mode.

Users should enable extend SSM protocol in whole network in this topology mode. Configuration of NE clock as below table shows:

NE1:






NE2, NE3:





NE4:






9.3.3 Self-loop network of OPCOM3105 Use several (more than 3) sets of OPCOM3105 to build up ring topology network as figure shows:

NE1, NE2 and NE3 make up SDH ring network. In normal running, the whole network synchronizes E1 line clock connected from external NE1. If E1 line clock of NE1 is invalid, the whole network


27

synchronizes with E1 line clock of NE2; if both NE1 and NE2 E1 line clocks are invalid, the whole network synchronizes local clock of NE1.

Users should enable extend SSM protocol in whole network in this topology mode. Configuration of NE clock as below table shows:

NE1:


1 E1 line clock source Set to be PRC 1




NE2:




3 E1 line clock source Set to be PRC 2


NE3:

Chapter 10 Network Topology


Overview Point-to-point topology Chain topology Ring topology

10.1 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.

10.2 Point-to-point topology

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

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

10.3 Chain topology

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

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

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


29

10.4 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.

10.4.1 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.

3 OPCOM3105 are used here to build ring network, the configuration of every device shows as the figure.

Configure DCC interface IP on OPCOM3105-A:


OPCOM3105#config Enter global configuration mode

OPCOM3105(config)# interface dcc 1 Enter dcc interface 1

OPCOM3105(config)#ip address 192.168.5.1 Configure dcc1 ip 192.168.5.1

OPCOM3105(config)#interface dcc 2 Enter dcc interface 2


Configure DCC interface IP on OPCOM3105-B:







Configure DCC interface IP on OPCOM3105-C:


32







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.

11.1.2 E1 network management channel In addition to support the use of standard D1D2D3-byte DCC NMS channel, OPCOM3105 devices provide remote management through independent E1 channels and VC12-channel in order to make information of network management pass through the SDH equipment of other manufacturers. This device support 2 E1 NMS channel, each with bandwidth of 192kbps. In addition, since OPCOM3105 E1 NMS channel can not interconnect with OPCOM3500E VCC, that OPCOM3500E VCC can not manage OPCOM3105 devices.

The specific configuration is as follows:

1. Configure the device using the E1 channel.



OPCOM3105(config)# dcc select e1channel E1 channel is applied to transmit the NMS information

2. Map E1 channels to VC12. Using the E1 channel for network management, each line of NMS information occupied independent VC12 timeslot, and VC12 is at random. In addition, for 8E1 equipment, E1 NMS channels are fixed to E1-9 and E1-10, on the 16E1 equipment, E1 NMS channels are fixed to E1-17 and E1-18. Take 8E1 equipment as an example:



OPCOM3105(config)# interface e1 9 Enter e1 interface configuration mode

OPCOM3105(config)# timeslot add sdh 1 vc12 1 Configure vc12-1 at SDH interface 1

OPCOM3105(config)# interface e1 10 Enter e1 interface configuration mode

OPCOM3105(config)# timeslot add sdh 2 vc12 1 Configure vc12-1 at SDH interface 2

3. Configure IP address of DCC channel and the RIP function. Refer to 11.1.1
