Ethernet ports Features

Switching card supports the following options:• 10/100 Base T• 10100 Base Fx• 1000 Base SX• 1000 Base LX

Supports auto negotiation Supports Flow control Supports Jumbo frames (up to 9216 bytes) Supports MDI-X 10/100 Base Ethernet ports can be configured in Full or Half

duplex mode. 1000 Base Ethernet ports in Full Duplex mode



Switching module : Salient Features

Line rate switching Supports 4K VLAN per port VLAN Stacking (Q-in-Q) is supported on all the GbE ports Per port rate limiting at 64 kbps granularity is supported on all the

client ports Switch has a built-in packet classification and filtering engine that

gives it the following capabilities• Layer 2-Layer 4 packet classification and filtering• Policing of flows based on programmable token bucket meters• Actions (e.g. dropping, setting lower priorities) on packets that are not in

conformance of programmed traffic profiles• Remarking of priorities (e.g.IP v6 DSCP, 802.1p) based on filter match

Traffic shaping using 1-8 CoS queues with strict priority, weighted round-robin, weighted fair queuing in scheduling



MAC and VLAN Switching

Ethernet switching is based on Destination MAC address + VLAN- ID Shared L2 address table

• Supports up to 16K entries• Entries can be configured aging or static

Shared Multicast Table with 256 entries Allows disabling of MAC learning on a per port basis VLAN Ids can be configured

• Port based• Protocol based

Supports• VLAN tagging and classification (IEEE 802.1 Q)• VLAN stacking (Q in Q)• Spanning Tree Protocol (IEEE 802.1 D)• Rapid Spanning Tree Protocol (IEEE 802.1 w)• MSTP (IEEE 802.1 s)• Link aggregation (802.3ad)



QoS Features

Rate of each port can be configured with granularity of 64 Kbps

• For FE: 64 Kbps to 10/100 Mbps

• For GbE: 64 Kbps to 1000 Mbps

Non conforming traffic can be dropped/back-pressured using PAUSE/RESUME thresholds.

Flow Classification based on• VLAN ID• IP ToS• IP DSCP• CoS• Source/Destination MAC

address• EtherType• Source/Destination IP Address• Source/Destination L4 address• Protocol field• Range of VLAN



Policing

Police simple• Rate limit the flow to meet committed information rate (CIR)• Burst size restricted to committed burst size (CBS).

Police Single-rate• Rate limit the flow to meet committed information rate (CIR)• Coloring based on committed burst size (CBS) and excess

burst size (EBS) Police Two-rate

• Rate limit the flow to meet committed information rate (CIR) and Excess information rate (EIR).

• Coloring based on committed burst size (CBS) and excess burst size (CBS).



Egress CoS queues

Supports 1- 8 CoS queues Supports following scheduling scheme

• Strict priority (SP)• Weighted round robin (WRR)• Weighted Fair queuing (WFQ)• Combination of (WFQ or WRR) and strict priority.

Traffic shaping to restrict bandwidth usage per CoS queue to minimum (BMIN) or maximum (BMAX) configurable bandwidth.

HOL is avoided by dropping traffic after a configurable threshold is exceeded

Supports WRED to avoid congestion



Broadband

Help operators provide New Revenue generating Broadband services

By providing Integration with existing networks Network Predictability (Resilience of RPR and SDH) Single Network Management Best-in-class scalability



Evolution of Broadband Services

Triple Play Services to residential subscribers• High Speed Internet Access, Video-on-demand, IP-TV,

Voice • Quadruple play with Wireless

Broadband Connectivity services to business subscribers• Leased Lines/Transparent LAN Services• VPN Services



Security Related Features

Access Control Lists: allows the traffic to be permitted or denied based on:

• VLAN ID• IP ToS• IP DSCP• CoS• Source/Destination MAC

address• EtherType• Source/Destination IP

Address• Source/Destination L4

address• Protocol field

Broadcast Storm control• Can be enabled/disabled on a per-port

basis Port mirroring

• Allows mapping of all incoming and outgoing packets on any specified port to a “probe” port

Performance Monitoring• The traffic statistics parameters can be

provided every 15 mins and on daily basis

• Parameters are monitored per flow and per port basis

• Allows loop-back on a per port basis• Supports connectivity fault

management as per 802.1ag
