1 Overview

1 Overview

This document gives an overview of the data service interface features supported by the 8620 SmartRouter, 8630 Smart Router and 8660 Smart Router The emphasis is on the software configuration

of the interfaces The existing components, their features and installation instructions are presented

in the documents mentioned below

8620 Smart Router Reference Manual, 8630 Smart Router Reference Manual, 8660 Smart Router Reference Manual and 8600 Smart Routers Hardware Installation Guide provide more information

about the Network Element (NE) including the supported Interface Modules (IFMs)

The 8620 Smart Router, 8630 Smart Router and 8660 Smart Router include Multiservice IFMs,which support both SDH [G.707] and SONET [T1.105] versions of the synchronous digitalhierarchy Similarly, the 8620 Smart Router, 8630 Smart Router and 8660 Smart Router also includeMultiservice IFMs which support both E1 and T1 modes The E1/T1 mode is configurable for eachMultiservice IFM and the Timing Module individually, but the supported configuration requires theIFMs to be in the same E1/T1 mode in the whole NE

In a typical case, the IFMs are shipped in the pre-configured mode desired by the customer.However, it is possible to configure the mode as late as in the installation and provisioningphases when the line cards and IFMs are taken to the inventory The E1/T1 mode is set by usingthe ETSI/ANSI setting, which is a fundamental inventory configuration and therefore the IFMconfiguration is reset to the factory default values during mode switchover

The ETSI/ANSI modes configuration examples of the Multiservice IFM are available in 8600 Smart Routers Equipment Management Configuration Guide.

The following table shows a summary of the supported modes:

1xchSTM-1/chOC-3 MS SDH+P12s (E1) SONET+DS14xchSTM-1/chOC-3 MS SDH+P12s (E1) SONET+DS124xchE1/chT1 MS P12s (E1) DS1

Trang 18

1 Overview

The 8620 Smart Router is a stand alone NE and uses a baseboard architecture with up to twoInterface Modules (IFMs) Thus, there are no separate line cards An operator can flexibly equipthe NE with various combination of the IFMs within the capacity limits of the 8620 Smart Routerand interface modules

In a typical case, a single IFM can forward traffic up to 2.5 Gbps and the NE can forward traffic

up to 3.5 Gbps actual physical line rate See section3.2.6 Adjustable Forwarding Capacityformore details about forwarding capacity

1.2.1 Supported IFMs

Detailed functionality of the 8620 Smart Router is covered in 8620 Smart Router Reference Manual.

The following table shows the supported IFMs

Trang 19

1 Overview

1.2.2 IFM Combinations

To prevent the 8620 Smart Router from being congested some combinations of high-capacityIFMs are restricted with default capacity values The combination marked below "Yes with BA(Bandwidth Allocation)" implies that it is allowed only when forwarding capacity adjustment is inuse within the high capacity Ethernet IFMs, see the details in3.2.6 Adjustable Forwarding Capacity

Trang 21

1 Overview

The 1xSTM-16/OC-48 POS IFM is not supported in the 8620 Smart Router.

1.3.1 General Line Card Architecture

The 8630 Smart Router and 8660 Smart Router use a line card architecture to allow a flexibleequipping of the NE There are two types of line card architectures supported: the IFC line card(with two variants IFC1 and IFC2) and the Ethernet line card of ELC1 type All line card types can

be plugged to any line card slots in the 8630 Smart Router and 8660 Smart Router The followingtable summarizes the differences between the IFC and the ELC1 line cards The major difference isthat the ELC1 has no IFM modularity, the number and type of the interfaces are fixed and that theELC1 provides more forwarding capacity than the IFC line card

Line Cards Differences

Modularity

2 IFMs per IFC 2 virtual modules (M0, M1)

Interfaces ATM, Ethernet, Multiservice,

The following table defines the terminology used in this section:

Backplane interface The interface providing slots inter-connectivity in the 8630 Smart Router

and 8660 Smart Router NEs Depending upon interconnection links,there are two types of slots interconnection: BIF and CIF

BIF Backplane Interface links (BIF) interconnecting slots of the backplane

interface The BIF links are used by IFC (1 & 2) and ELC1 line cards.CIF Cluster Interface links (CIF) interconnecting slots of the backplane

interface in a cluster The CIF links are used by ELC1 line cards

Cluster A group of four slots

Trang 22

Capacity and Slots

Each IFC line card interconnects with other line cards via the backplane interface with a 3.5 GbpsBIF links, providing a total capacity of up to 42 Gbps (8660 Smart Router) or up to 14 Gbps (8630Smart Router)

In a typical case, a single IFM can forward traffic up to 2.5 Gbps and a single IFC line card canforward traffic up to 3.5 Gbps actual physical line rate See section3.2.6 Adjustable ForwardingCapacityfor more details about forwarding capacity

The following figure provides an example illustrating the backplane interface links connectivityfor an IFC line card installed in slot 6 of the 8660 Smart Router

in total three clusters available For more details about ELC1 supported subrack versions, power

feeding options and cooling, please refer to 8630 Smart Router Reference Manual and 8660 Smart Router Reference Manual.

Capacity and Slots (Clusters)

The ELC1 uses the backplane interface BIF and CIF links in the following ways depending on thecounterpart line card (IFC or ELC1) and its position in the subrack:

• ELC1 to ELC1 in the same cluster The backplane interface CIF links provide 10 Gbps and BIFlinks 10 Gbps forwarding capacity

• ELC1 to ELC1 in different clusters The backplane interface BIF links provide 10 Gbps ing capacity

forward-• ELC1 to IFC in the same cluster The backplane interface BIF links provide 3.5 Gbps stipulated

by the IFC line card forwarding capacity

• ELC1 to IFC in different clusters The backplane interface BIF links provide 3.5 Gbps stipulated

by the IFC line card forwarding capacity

3 Ethernet Interface Modules

3 Ethernet Interface Modules

An Ethernet interface functionality is implemented according to [IEEE 802.3] At ingress, anEthernet interface accepts Ethernet II frames (type/length = 0x0600-FFFF) and 802.3 LLC-SNAPframes (type/length = 0x0000-05FF) At egress, the Ethernet interface always generates Ethernet

II frames

A NE supports VLAN tagging and all interfaces can accept VLAN tagged, priority-tagged anduntagged frames Also double VLAN tagged frames are supported In the egress direction thepriority tag is not supported An interface performs input filtering based on the VLAN identifiersand can be configured to optionally discard all untagged and priority-tagged frames A VLANIdentifier (VID) can be selected from the full VID range (1–4094 are valid values, 0 and 4095 are

reserved) The 8600 system Ethernet functionality is covered in 8600 Smart Routers Ethernet Configuration Guide.

There are two types of Ethernet IFMs supported in the 8620 Smart Router, 8630 Smart Routerand the 8660 Smart Router:

• Regular Ethernet IFMs - the forwarding capacity of these IFMs is fixed

• High capacity Ethernet IFMs - the forwarding capacity of these IFMs may be fixed or dynamicallyadjusted

Overview

The 8-port Gigabit Ethernet IFM provides eight optical 1000BASE-X interfaces

• 1000BASE-X interfaces support full duplex mode

• Flexible user-configurable allocation of the IFM capacity between the GE Ethernet interfaces in

20 Mbps steps By default the capacity is shared equally between all 8 interfaces See chapter

3.2.6 Adjustable Forwarding Capacityfor more detailed information on how the 8x1000BASE-Xcan be configured with a fellow IFM in the same line card

• The architecture of IFM consists of two interface banks Ports 0 3 belong to the first bank,while ports 4 7 to the second bank To maximize the throughput of the IFM it is required

to use ports in both banks Both interface banks support max 2 Gbps throughput

• Port shaper, which limits the egress bandwidth of the Ethernet interface The limit is

user-config-urable between 6 1000 Mbps in 1 Mbps steps using eth bandwidth rate-limit command Before the Ethernet port shapers are configured using eth bandwidth rate-limit command it is impor- tant that the forwarding capacity is allocated properly for the IFM using bandwidth-if command

as described in3.2.6 Adjustable Forwarding Capacity The bandwidth allocation value shouldalways be larger than the shaper value to allow the port shaper to limit traffic

Trang 37

In the 8x1000BASE-X IFM, Ethernet line loopback supports only a maximum rate up to 800 Mbps If an Ethernet line loopback is activated with a rate exceeding 800 Mbps, packet loss will be observed.

When two interfaces are configured to operate at full GE capacity, it is recommended to shutdown the other unused interfaces or remove cabling to prevent them from interfering with the configured interfaces.

If port capacity has been configured to 0, the interface must be disabled with shutdown
