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

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

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
