This chapter provides the information on bridge connection and packet statistics
6.1

Bridging in General

Bridging bases the forwarding decision on the MAC (Media Access Control), or hardware address, while
routing does it on the network layer (IP) address. Bridging allows the Prestige to transport packets of network
layer protocols that it does not route, for example, SNA, from one network to another. The caveat is that,
compared to routing, bridging generates more traffic for the same network layer protocol, and it also
demands more CPU cycles and memory.
For efficiency reasons, do not turn on bridging unless you need to support protocols other than IP on your
network. For IP, enable the routing if you need it; do not bridge what the Prestige can route.
6.2

Bridge Ethernet Setup

Basically, all non-local packets are bridged to the WAN. Your Prestige does not support IPX.
Syntax:
bridge cnt disp <channel>
This command displays the connection statistics for a specified channel.
An example is shown next.
ras> bridge cnt disp 1
