Limiting FTP Access

FTP access can be limited by:

HDisabling FTP access completely.

HRequiring a user ID and password to login.

HLimiting FTP bandwidth.

"Procedure

To limit FTP access when the session is not on the TS Management Link:

1. Select the Telnet and FTP Session options.

Main Menu

→

Configuration

→

Management and Communication

→

Telnet and FTP Sessions

2. Set the following configuration options, as appropriate.

To . . . Set the configuration option . . .

Disable FTP FTP Session to Disable.

Require a login Login Required to Enable.

NOTE: User ID and password combinations

must be defined. See

Creating a Login

.

If you want to allow users to configure the unit

or perform file transfers, including downloads,

keep the access at Level-1.

Level-1 access is required to download

software to the unit, or to upload or download

configuration files. Level-3 is sufficient for

NMS access for SLV historical information.

Limit bandwidth for FTP FTP Max Transfer Rate to a rate less than the

network line speed, typically less than or

equal to the CIR.

This method is not recommended if SLV

reports are desired since FTP is required to

generate the reports.

3. Save your changes.

See

Configuring Telnet and/or FTP Session Support
