Configuring the Cisco 10000 Series Router for High Scalability
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 ).
Note The No Session Timeout parameter indicates the length of time a tunnel persists when there are no
sessions in the tunnel.
Example 2-5 Configuring an L2TP Tunnel Password
Router(config)# vpdn-group tunnel1
Router(config-if)# l2tp tunnel password 7
Example 2-6 Configuring the No Session Timeout Parameter
Router(config)# vpdn-group tunnel1
Router(config-if)# l2tp tunnel nosession-timeout 30
