NOTE
If you disable Telnet access, you will not be able to access the CLI except through a serial connection
to the management module, nor will you be able to use some of the features in IronView Network
Manager. If you disable SNMP access, you will not be able to use IronView Network Manager or
third-party SNMP management applications.
Disabling Telnet access
Telnet access is enabled by default. You can use a Telnet client to access the CLI on the device
over the network. If you do not plan to use the CLI over the network and want to disable Telnet
access to prevent others from establishing CLI sessions with the device, enter the following
command.
BigIron RX(config)# no telnet-server
To re-enable Telnet operation, enter the following command.
BigIron RX(config)# telnet-server
Syntax: [no] telnet-server
Disabling Web management access
If you want to prevent access to the device through the Web management interface, you can
disable the Web management interface.
NOTE
As soon as you make this change, the device stops responding to Web management sessions. If you
make this change using your Web browser, your browser can contact the device, but the device will
not reply once the change takes place.
To disable the Web management interface, enter the following command.
BigIron RX(config)# no web-management
To re-enable the Web management interface, enter the following command.
