Before you begin

In Trusted Computing Group (TCG) terminology, the edge switches in a Nortel

SNA solution function as the Policy Enforcement Point. In this document, the term network access device is used to refer to the edge switch once it is configured for the Nortel SNA network.

The following edge switches can function as network access devices in the Nortel

SNA solution:

• Ethernet Routing Switch 8300

• Ethernet Routing Switch 5510, 5520, and 5530

Before you can configure the edge switches as network access devices in the

Nortel SNAS 4050 domain, you must complete the following:

• Create the domain, if applicable. If you ran the quick setup wizard during initial setup, Domain 1 has been created. For more information about creating

a domain, see “Configuring the domain” on page 117 .

• Configure the edge switches for Nortel SNA (see

“Nortel SNAS 4050 configuration roadmap” ,

step 4 on page 45

). For detailed information about configuring the edge switches for Nortel SNA, see Release Notes for the

Ethernet Routing Switch 8300, Software Release 2.2.8 (316811-E) or Release

Notes for Nortel Ethernet Routing Switch 5500 Series, Software Release

4.3 (217468-B).

For secure communication between the Nortel SNAS 4050 and the network access device, each must have knowledge of the other’s public SSH key. After you have added the network access device to the Nortel SNAS 4050 domain, you must

exchange the necessary SSH keys (see “Managing SSH keys using the CLI” on page 84 or

“Managing SSH keys using the SREM” on page 102

).
