Introduction

This document provides information on how to configure the FTP port mode on a Cisco CSS 11000 Series Content Services Switch. The client issues the retrieval request and sets up the listening port. The client issues a port command to the FTP server. This command informs the server of the port to which the client listens for the data connection. The server establishes the connection to the address that the port command indicates.

Step-by-Step Instructions

Complete these steps in order to configure the FTP port mode on the CSS 11000.

Issue the ftp-record command for the destined servers, and specify the username and password.

44-css150(config)#ftp-record ns1 172.18.124.206 anonymous "some@where.com"
44-css150(config)#ftp-record ns2 172.18.124.207 anonymous "some@where.com"

Issue the keepalive type ftp command with a predefined FTP record in order to configure service for each server.

44-css150(config)#service ns1
Create service <ns1>, [y/n]:y
44-css150(config-service[ns1])#ip address 172.18.124.206
44-css150(config-service[ns1])#keepalive type ftp ns1
44-css150(config-service[ns1])#active

Configure a content rule with a virtual IP (VIP) address for the clients to point to when they initiate the FTP session.

44-css150(config)#owner groupftp
Create owner <groupftp>, [y/n]:y
44-css150(config-owner[groupftp])#content groupftp
Create content <groupftp>, [y/n]:y
44-css150(config-owner-content[groupftp-groupftp])#add service ns1
44-css150(config-owner-content[groupftp-groupftp])#add service ns2
44-css150(config-owner-content[groupftp-groupftp])#vip address 172.18.124.208
44-css150(config-owner-content[groupftp-groupftp])#application ftp-control
44-css150(config-owner-content[groupftp-groupftp])#protocol tcp
44-css150(config-owner-content[groupftp-groupftp])#port 21
44-css150(config-owner-content[groupftp-groupftp])#act

Issue the group command in order to configure a source group.

44-css150(config)#group groupftp
Create group <groupftp>, [y/n]:y
44-css150(config-group[groupftp])#add service ns1
44-css150(config-group[groupftp])#add service ns2
44-css150(config-group[groupftp])#vip address 172.18.124.208
44-css150(config-group[groupftp])#active
