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.

GLC1320G-55 User’s Guide 7

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.

GLC1320G-55 User’s Guide

Chapter 1 Introducing the GLC1320G-55

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.

GLC1320G-55 User’s Guide

Chapter 1 Introducing the GLC1320G-55

Isolation (per-VLAN)

Use isolation to block the subscribers in a specific VLAN from sending traffic directly to each other.

Packet Filter

The GLC1320G-55 supports packet filtering based on protocol. You can configure the GLC1320G-55 to accept all packets, accept PPPoE packets only or block any combination of the following protocols: IP, ARP, DHCP, EAPOL, PPPoE, NetBios or IGMP.

MAC (Media Access Control) Filters

Use the MAC filter to filter incoming frames based on MAC (Media Access Control) address(es) or the OUI (Organizational Unit Identifier) that you specify. You may enable/disable the MAC filter on specific ports. You may specify up to ten MAC addresses per port.

MAC (Media Access Control) 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 limit on individual ports.

IGMP Snooping

The GLC1320G-55 supports IGMP snooping enabling group multicast traffic to be only forwarded to ports that are members of that group; thus allowing you to significantly reduce multicast traffic passing through your GLC1320G-55.

IGMP Filter

The IGMP filter defines multicast groups a port can join. You can create IGMP filter profiles which allow access to a multicast group, then assign the IGMP filter to a specific subscriber slot.

Multicast Group Limit

You can limit the number of IGMP multicast groups a subscriber on a port can join. You may enable/ disable the multicast group limit on individual ports.

Discarding of IGMP Query Messages

The GLC1320G-55 discards IGMP query messages received from subscriber ports. This prevents subscribers from hosting IGMP multicast servers.

IGMP Statistics

The GLC1320G-55 records the number of active users in an IGMP multicast channel (multicast group). The GLC1320G-55 also records IGMP message statistics on a per port basis to ease management and troubleshooting.

GLC1320G-55 User’s Guide

Chapter 1 Introducing the GLC1320G-55

IGMP Message Rate Limiting

The GLC1320G-55 can limit how many IGMP message packets a subscriber can send per second. This prevents subscribers from flooding the multicast server.

Static Multicast

Use static multicast to allow incoming frames based on multicast MAC address(es) that you specify. This feature can be used in conjunction with IGMP snooping to allow multicast MAC address(es) that are not learned by IGMP snooping. You can use static multicast to pass routing protocols, such as RIP and OSPF.

Multicast Bandwidth Control

The GLC1320G-55 supports static bandwidth control for multicast traffic. Bandwidth limits can be assigned to multicast channels. During IGMP snooping, the system checks the total bandwidth usage to see if it exceeds the specified limit. If the specified limits are reached, the system restricts the joining of multicast groups.

DHCP Relay

DHCP (Dynamic Host Configuration Protocol RFC 2131 and RFC 2132) allows individual computers to obtain TCP/IP configuration at start-up from a server. You can configure the system as a DHCP relay agent to have another DHCP server provide TCP/IP configuration for the clients. In addition, you can set the system to forward client DHCP requests to specific DHCP servers based on the VLAN ID. You can also specify up to two DHCP servers for each VLAN to provide failover protection.

DHCP Relay Option82

The system supports DHCP relay agent82 (RFC 3046) that adds additional information to client DHCP requests that the MSC relays to a DHCP server. It also supports adding the sub-option 2 (Remote ID) with additional information.

DHCP Snooping

DHCP snooping allows the system to identify packets with DHCP server assigned IP address(es) and block access of devices using unknown IP addresses on a subscriber port. You can also manually add static IP addresses to the DHCP snooping table.

System Error Logging

The system error log will record error logs locally to the management switch card memory.

Remote Firmware Upgrade

You can use FTP or SFTP to perform configuration backup/restore and firmware upgrade from a remote location.

GLC1320G-55 User’s Guide

Chapter 1 Introducing the GLC1320G-55

Anti-IP Address Spoofing

With DHCP snooping, the GLC1320G-55 records which IP addresses are assigned on each port. The GLC1320G-55 drops packets from a device using a different IP address.

Anti-MAC Address Spoofing

The GLC1320G-55 checks to make sure the MAC addresses of the devices connected to the subscriber ports are not the same as MAC addresses of devices connected to the Ethernet network. This protects the network from disruptions of service caused by subscriber devices spoofing the MAC address of ISP servers.

PPPoE Intermediate Agent Information

Similar to DHCP relay option82, you can set the system to insert line information into client PPPoE Active Discovery Initialization (PADI), PPPoE Activ e Discovery R equest (P ADR), and upstream PPP oE Active Discovery Terminate (PADT) packets. This allows a PPPoE termination server to identify and authenticate a PPPoE client.

T ransparent LAN Service (TLS)

Use TLS (also known as VLAN stacking) to add an outer VLAN tag to the inner IEEE 802.1Q tagged frames that enter the network. By tagging the tagged frames (“double-tagged” frames), the service provider can manage up to 4,094 VLAN groups with each group containing up to 4,094 customer VLANs. This allows a service provider to provide different services based on specific VLANs, for many different customers.

Classifier and Policy

You can create an ACL profile and map it to individual ports to define actions to be performed on traffic that matches the ACL profile. The ACL profile specifies criteria such as the IP address, port number, or protocol type, and so on.

Console Port

Use the console port for debugging and troubleshooting.

3.2 Data Transmission

The link is up, but data cannot be transmitted.

Table 8 Data Transmission Troubleshooting

STEPS CORRECTIVE ACTION

1 Check the line card’s port isolation settings.

If the subscriber is having problems with video or other high-bandwidth services, make

sure the line card’s port’s data rates are set high enough. 2 Check the VLAN configuration. 3 Ping the MSC from a computer at the subscriber’s location.

If you cannot ping, connect a Ethernet switch to a subscriber slot (th at is known to

work).

If the Ethernet switch works with a different subscriber slot, there may be a problem with

the transceiver in the original SFP slot or the configuration for the SFP slot.

If using a different slot does not work, try a different Ethernet switch with the original

slot.

sys

3.3 Local Server

The computer behind an Ethernet switch cannot access a local server connected to the line card.

GLC1320G-55 User’s Guide

Table 9 Local Server Troubleshooting

STEPS CORRECTIVE ACTION

1Refer to Section 3.2 on page 20 to make sure that the subscriber is able to transmit to

the line card. 2 Make sure the computer behind the Ethernet switch has the correct gateway IP address

configured. 3 Check the VLAN configuration (refer to the MSC User’s Guide). 4 Check the cable and connections between the line card and the local server. 5 Try to access another local server.

If data can be transmitted to a different local server, the local server that could not be

accessed may have a problem.

3.4 Management and Configuration

Chapter 3 Troubleshooting

The line card is not manageable.

The line card always uses the default configuration. Any changes you made to the line card are stored on the MSC. By default, the MSC is allowed to manage every line card. Use the command on the MSC to see a line card’s connection status. If you still cannot manage the line card from the MSC, the line card’s configuration file may be damaged or the firmware may be old, you may need to restore the default configuration file or upload new firmware using the line card’s console port.

Note: The MSC resets the line card after a period of inactivity on the line card. This may

damage the line card if you are uploading the default configuration file or new firmware to the line card. Use the lcman disable <slot> command on the MSC to prevent the MSC from managing the line card. After you upload the file successfully, use the lcman enable <slot> command on the MSC to allow the MSC to manage the line card again. Refer to the MSC User’s Guide for details about commands.

3.4.1 Uploading the Default Configuration File via Boot Commands

Obtain the default configuration file, unzip it and save it in a folder. Use a console cable to connect a computer with terminal emulation software to the line card’s console port. Pull out the line card and push it back in, you will see the initial screen. When you see the message
