AlliedView NMS Administration Guide
6.1.1 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).
6.1.2 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.
6.1.3 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.
6.1.4 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.
Software Upgrade support for
EPSR and EPSR+
During upgrade of iMAP devices, nodes are
updated in proper order to keep the EPSR
ring in-service. If other nodes need to be
added to upgrade sequence, GUIs appear.
If EPSR had not been configured
correctly, a GUI with an error
message appears. Refer to 6.20.
Diagnostic Audit
Provides the capability to run diagnostic
audits on certain network entities.
Currently, the auditable entities are:
• Network VLANs
• CES Circuits
Refer to 6.21.
Port Authentication Refer to 6.22.
a. VLAN Translations may be needed when configuring the VLANs on the iMG6x6MOD. This involves interaction
between the iMG and Port Profiles. Refer to 7.9.3
