AlliedView NMS Administration Guide

13.1.1 Profile Management

Since most of the parameters in the configuration of certain ports or devices will be the same throughout the network,

profile management is a way to set up these parameters (through profiles) and then apply them throughout the network in

only a few steps and with less chance of error. Profile Management also allows the network administrator to easily re-deploy

changes in a stored configuration to the devices/ports in the network. Finally, the AlliedView NMS allows the user to

determine whether the configuration on a device or port still matches the configuration that was defined for it using Profile

Management (and is therefore in-sync).

13.1.2 Quality of Service

The main strategy in providing QoS is to first classify and segregate traffic into separate flows. These flows can then be

managed separately through the network with each flow getting a specified level of service.

The Rapier, Switchblade, and iMAP devices provide this function, with some variation between the device types. Refer to the

User Guides for each device type for detailed information on how they provide QoS.

13.1.3 Protection Switching (EPSR)

The EPSR feature protects the parts of the network that have a ring topology. Key components that are configured are

Control VLANs, Domains, and Protected VLANs.

A Control VLAN is configured on the set of devices, and is used to send and receive control messages over the ring network.

The devices that are included in the control VLAN make up the Domain of the control VLAN.

The VLANs that require fault protection are configured on all the ring ports and are assigned to the EPSR domain. These

VLANs are called Protected VLANs.

13.1.4 Circuit Emulation Service (CES)

The iMAP devices use the CES8 card to transport T1 point to point across an Ethernet network. This CES is in unstructured

mode; in this mode, the CES8 creates a “pseudo-span” across the Ethernet network that acts like a virtual wire connection

that accepts a bit stream into the pseudo-span, and recreates that same stream out of the pseudo-span.

When configuring CES, the user provisions through forms the functional components of the CES8 and iMAP device, as well

as the network VLANs that connect devices and networks.

Note: Future releases of iMAP software will allow structured mode transport, which allows manipulation of the individual 64kbps

channels.

13.1.5 NTE8 Service

The NTE8 card allows DS1/E1 facilities to connect (backhaul) the ethernet network, with both ends of the DS1/E1

connections being on iMAP 9000 devices. Refer to the iMAP User Guide for a complete description of the NTE8 configuration.

Note: Refer to 10.21 and 11.19 for an overview of the NTE8 card and DS1/E1 port attributes.

Diagnostic Audit

Provides the capability to run diagnostic

audits on certain network entities.

Currently, the auditable entities are:

• Network VLANs

• CES Circuits

Refer to 13.18.

Port Authentication Refer to 13.19.
