Cisco AS5x00 Case Study for Basic IP Modem Services

Section 1 Network Design and Case Study Overview
Network Service Definition
The network service definition for each company is different:

Maui Onions’ scaling projections are much smaller than THEnet’s projections. For this reason,
THEnet requires higher density network access servers (that is, THEnet requires a Cisco AS5800
instead of a Cisco AS5300).

Maui Onions cares more about security and less about billing. THEnet cares more about billing and
less about security.

THEnet has a higher V.90 priority and, for this reason, will spend more time fine tuning V.90 than
Maui Onions. THEnet’s primary objective is to get 56K modem-connections enabled. For THEnet,
higher connect speeds equate to increased sales, whereas Maui Onions’ revenue stream does not
depend on high modem-connect speeds. Maui Onions will use dial-up service for its employees.

AAA design is important to Maui Onions. A defined security policy protects enterprise network
resources.

Maui Onions enables its network administrator users to change their own passwords by using an
EXEC shell login. THEnet allows its users to change their own passwords using a web page
interface.

For the short term, both companies store users’ passwords in a local-username database inside the
router. In the long term, Maui Onions will scale to use TACACS+ security. THEnet will use
RADIUS security.

Maui Onions supports per-user attribute definitions. THEnet provides Internet access only.
Maui Onions enables specific onion vendors to dial in, pass through filters, and access specific
devices.
