11-12 CHAPTER 11: ETHERNET LANS AND BRIDGES IN THE 7600 CARD

Local Bridged-LAN

Environment

For the purpose of forming bridged-LAN environments, the 7600 Card

provides up to 16 internal bridges that can be configured by

management. On setup, one bridge is allocated to each bridged-LAN

environment that is to operate in the 7600 Card. Each local LAN segment

is then attached to a port of the bridge corresponding to the

bridged-LAN environment in which it is to operate. bridges are

configured by management in the Fast Setup (see Chapter3) or in the

Virtual LAN Configuration menu see (Chapter5). For management

purposes the bridges are numbered from 0 to 3 in each one of the four

contexts. Figure11-5 shows two local bridged-LAN environments,

Engineering and Finance, connected to bridges on a 7600 Card.

Connection to the

ATM Network

In Chapter 12, the possibility of connecting bridges in the 7600 to the

ATM network is discussed. For each bridge, an ATM connection can be

configured through which the bridge is attached to an Emulated LAN (see

“Bridges in the 7600 Card” on page 12-10).
