Security
Where <url> is the DNS name of the switch. For example,
configure netlogin base-url
network-access.ne
t makes the switch send DNS responses back to the netlogin clients when a DNS
query is made for
network-access.net
.
To configure the network login redirect page, use the following command:
configure netlogin redirect-page <url>
Where
<url>
defines the redirection information for the users once logged in. This redirection
information is used only in case the redirection info is missing from RADIUS server. For example,

redirects all users to this URL
after they get logged in.
To enable or disable the network login session refresh, use one of the following commands:
enable netlogin session-refresh {<minutes>}
disable netlogin session-refresh
Where
<minutes>
ranges from 1 - 255. The default setting is 3 minutes.
enable netlogin
session-refresh {<minutes>}
makes the logout window refresh itself at every configured time
interval.

Switch Protection
Switch protection features enhance the robustness of switch performance. In this category are the
following features:
• Routing Access Profiles
• Denial of Service Protection
Routing Access Profiles
Routing access profiles are used to control the advertisement or recognition of routing protocols, such as
RIP or OSPF. Routing access profiles can be used to ‘hide’ entire networks, or to trust only specific
sources for routes or ranges of routes. The capabilities of routing access profiles are specific to the type
of routing protocol involved, but are sometimes more efficient and easier to implement than access lists.
