Scenario

The basic Nortel SNA network in this example includes: one Nortel SNAS 4050 device; two edge switches (one Ethernet Routing Switch 8300 and one Ethernet

Routing Switch 5510) functioning as network access devices; an Ethernet Routing

Switch 8600 functioning as the core router; a BCM call server; a DNS server; a

DHCP server; and a remediation server. The edge switches function in Layer 2 mode.

Figure 235 on page 780 illustrates the network configuration.
