Chapter 2 Scalability and Performance
Configuring the Cisco 10000 Series Router for High Scalability
Configuring Parameters for RADIUS Authentication
If your network uses a RADIUS server for authentication, set the small, middle, and big buffers by using
the
buffers
command.
Table 2-4
lists the buffer sizes to configure (and see
Example 2-3
).
Example 2-3
Configuring Buffer Sizes
Router(config)# buffers small perm 15000
Router(config)# buffers mid perm 12000
Router(config)# buffers big perm 8000
Typically, if the RADIUS server is only a few hops away from the router, we recommend that you
configure the RADIUS server retransmit and timeout rates by using the
radius-server
command.
Table 2-5
lists the recommended settings (and see
Example 2-4
).
Example 2-4
Configuring RADIUS Server Parameters
Router(config)# radius-server retransmit 5
Router(config)# radius-server timeout 15
Configuring L2TP Tunnel Settings
Configure an L2TP tunnel password using Cisco IOS Release 12.2(4)BZ1 or later. We recommend that
you configure the L2TP tunnel parameters listed in
Table 2-6
(and see
Example 2-5
,
Example 2-6
, and
Example 2-7
).
