Introducing the GLC1320G-55

1.1 GLC1320G-55 Overview

The GLC1320G-55 is a Gigabit Ethernet Line Card with 20 SFP slot connector slots for fiber-based SFP (mini-GBIC) transceivers (16 for SFP transceiver and 4 for CSFP/SFP). It connects through fiber-optic cables to other Ethernet switches that support fiber connections (like the FSG1100HN, GS2200-8 or FMG3024/3025) located at the subscriber’s premises.

Figure 1 GLC1320G-55 Overview

CHAPTER 1

The GLC1320G-55 supports various SFP transceivers to satisfy a wide range of loop length requirements (see Table 3 on page 15 for details).

The GLC1320G-55 lets you easily implement high-speed optical FTTH (Fiber To The Home) or FTTB (Fiber To The Building) networks. The GLC1320G-55’s 1000 Mbps symmetric bandwidth persubscriber is perfect for offering IP-based triple play (voice, video, and Internet) services

The GLC1320G-55 aggregates layer-2 traffic from Ethernet subscribers to the IES system. The GLC1320G-55’s Ethernet QoS, security, and multicast features make it easy to deploy, provide subscribers with differentiated classes of service, and add new services.

Refer to the directions and safety warnings in the IES User's Guide to install the line card in the IES.

See the MSC User’s Guide for detailed information on configuring the line card.

1.2 Features

Here is a partial list of the GLC1320G-55’s features.

CSFP/SFP Slots

Install CSFP or SFP transceivers to connect to Ethernet switches. The Compact SFP (CSFP) transceivers consist of two bidirectional channels inside a conventional SFP form factor.

Chapter 1 Introducing the GLC1320G-55

SFP Slots

Install SFP (Small Form-factor Pluggable) transceivers to connect to Ethernet switches.

Discovery and Dependency Mapping Inventory (DDMI)

Discovery and Dependency Mapping Inventory (DDMI) reads the transceiver temperature and voltage.

SFP/CSFP Tx Manual Power Disable

Manually disables the transfer (Tx) power of individual transceivers.

Subnet Based VLAN

Subnet based VLAN allows you to group traffic into logical VLANs based on the source IP subnet you specify . When a fr ame is received on a port, the GL C1320G-55 checks if a tag is added already and the IP subnet it came from. The untagged packets from the same IP subnet are then placed in the same subnet based VLAN. One advantage of using subnet based VLANs is that priority can be assigned to traffic from the same IP subnet.

xVLAN

xVLAN changes the VLAN IDs (VIDs) of subscriber traffic before sending it to the service provider’s network. It also changes the VIDs of traffic from the service provider’s network before sending it to the subscriber. This lets you use unique VLANs for each subscriber but still deploy all the CPE devices with the same VLAN configuration.

Upstream Broadcast Storm Control

Broadcast storm control lets you set limits for how many broadcast, multicast and destination lookup failure (DLF) packets a port receives per second from the subscriber.

Downstream Broadcast VLAN Control

Downstream broadcast VLAN control allows you to block downstream broadcast packets from being sent to specified VLANs on specified ports. This helps to reduce downstream bandwidth requirements on a subscriber line.

MAC Count Limit

You can limit the number of MAC addresses that may be dynamically learned on a port. You may enable/disable the MAC count filter on individual ports.

Rate Limiting

Rate limiting on the subscriber ports allows service providers to offer tiered service in increments of 64 Kbps. This service differentiation is not only to fulfill the needs of different customers, but also to provide a network infrastructure that combines guaranteed performance and flexibility in service provisioning.

Loop Guard

Loop guard protects against network loops on the edge of you network.

Double Tag Mode (DT)

For untagged packets, DT adds outer VLAN tag and inner VLAN tags. For tagged packets, DT adds an outer VLAN tag.

System Monitoring

• System status (link status, rates, statistics counters)

• Temperatures, voltage reports and alarms.

Configurable Alarms

The system allows you to customize the priority levels of individual alarms and the alarm severity threshold for recording alarms on an individual slot(s).

Alarm LED

An ALM (alarm) LED lights when the GLC1320G-55 is overheated, the voltage readings are outside the tolerance levels, a fan fails, or another alarm with a severity level of MAJOR or CRITICAL occurs.

IEEE 802.1Q Tagged VLAN

Your GLC1320G-55 uses the IEEE 802.1Q Tagged VLAN (Virtual Local Area Network), which allows it to deliver tagged/untagged frames to and from its ports. The IES supports up to 4094 individual VLANs.

Multicast VLAN

Multicast VLAN is designed for applications (such as Media-on-Demand (MoD)) using multicast traffic across an Ethernet ring-based service provider network. Multicast VLAN allows one single multicast VLAN to be shared among different subscriber VLANs on the network. This improves bandwidth utilization by reducing multicast traffic in the subscriber VLANs and simplifies multicast group management.

IEEE 802.1x Port-based Authentication

The GLC1320G-55 supports the IEEE 802.1x standard for centralized user authentication and accounting management through an optional network authentication (RADIUS) server.

Port Isolation

The GLC1320G-55's port isolation feature allows each port to communicate with the uplink port but not communicate with each other. This option is the most limiting but also the most secure.
