Foundry Configuration Guide for the FESX, FSX, and FWSX
D - 4 © Foundry Networks, Inc. December 2005
Priority mapping using ACLs
• ToS-QoS mapping for routed packets using ACLs is supported. ToS-
QoS mapping for switched packets is not supported.
XXX
Rate limiting
• Port-based inbound rate limiting is supported. Port-based outbound
rate limiting is not supported.
• FESX support starts in release 01.1.00
• Fixed rate limiting is not supported on 10-Gigabit Ethernet ports.
XXX
sFlow
• RFC 3176
• FESX, FWSX, and FSX support sFlow sampling of inbound traffic
only. These devices do not sample outbound packets.
XXX
Static MAC entries with option to set priority X X X
Trunk groups
• FESX, FWSX, and FSX devices support up to 4-port trunk groups
(trunk groups on these devices can have 2, 3, or 4 ports)
XXX
Layer 2 Features
802.1d Spanning Tree Support
• Enhanced IronSpan support includes Fast Port Span and Single-
instance Span
• PVST/PVST+ compatibility
• Rapid Spanning Tree support allows for sub-second convergence
XXX
802.1p Quality of Service (QoS)
• Strict Priority (SP)
• Weighted Round Robin (WRR)
• Support of 8 priority queues
XXX
802.1W Rapid Spanning Tree
• Final IEEE standard
XXX
Dynamic Host Configuration Protocol (DHCP) Assist X X X
IGMPv2 snooping (Layer 2 Multicast) X X X
Metro Ring Protocol 1 (MRP 1)
• These devices can be MRP masters or MRP members (for different
rings).
• The RHP received counter on non-master MRP nodes increment.
This is different on other devices that support MRP 1.
