Network Login
Summit 200 Series Switch Installation and User Guide 79
NOTE
Because network login is sensitive to state changes during the authentication process, Extreme
Networks recommends that you do not log out until the login process is complete. The login process is
complete when you receive a permanent address.
DHCP Server on the Switch
A DHCP server with limited configuration capabilities is included in the switch to provide IP addresses
to clients. An external DHCP server is also required because the provided server does not address or
renew the DHCP lease after a client is authenticated.
DHCP is enabled on a per port, per VLAN basis. To enable or disable DHCP on a port in a VLAN, use
one of the following commands:
enable dhcp ports vlan
disable dhcp ports vlan
configure vlan netlogin-lease-timer
Displaying DHCP Information
To display the DHCP configuration, including the DHCP range, DHCP lease timer, network login lease
timer, DHCP-enabled ports, IP address, MAC address, and time assigned to each end device, use the
following command:
show vlan [dhcp-address-allocation | dhcp-config]
Displaying Network Login Settings
To display the network login settings, use the following command:
show netlogin {ports vlan }
Disabling Network Login
Network login must be disabled on a port before you can delete a VLAN that contains that port. To
disable network login, use the following command:
disable netlogin ports vlan
Additional Configuration Details
This section discusses additional configuration details such as switch DNS names, a default redirect
page and session refresh.
URL redirection requires the switch to be assigned a DNS name. The default name is
network-access.net . Any DNS query coming to the switch to resolve switch DNS name in
unauthenticated mode is resolved by the DNS server on the switch in terms of the interface (to which
the network login port is connected to) IP-address.
To configure the network login base URL, use the following command:
configure netlogin base-url
