Routing Features
In addition to Layer 2 and Layer 3 switching, the Rapier switch provides a
wide array of multiprotocol routing, security and network management
features.
IP routing is performed at wire-speed. Other Layer 3 routing is performed by the CPU,
and increasing the routing load on the CPU decrease its performance.
Some features require the addition of WAN interfaces via Network Service
Modules (NSMs) and Port Interface Cards (PICs) installed in the NSM bay on
the rear of the switch.
Features provided by the routing software suite include:
■ IP version 4 routing.
■ Network Address Translation (NAT) (not between switch ports)
■ Dynamic IP Address Assignment
■ IP Dynamic Filtering Firewall
■ IP Multihoming
■ IP RIP and IP RIPv2
