  • Page 11: Server Load Balancing Concepts

    Server Load Balancing Concepts The Px series application switch marks the next step in server load balancing. Using a revolutionary hardware design, the Px series application switch is designed to help website administrators achieve levels of availability and scalability never before possible.

  • Page 12: Terms

    • Allowing movement of web content without extensive re-linking of the site Terms The Px series application switch creates a level of abstraction between the real servers and the Internet, by configuring a virtual IP (VIP) address and port on the application switch.

  • Page 13: Load Balancing Modes

    IP address of the request to point to one of the internal IP addresses of the Px series application switch. When the server responds to the request, the application switch rewrites the response so that it appears to originate from its VIP address, and forwards the response to the client.

  • Page 14: Layer 7 Load Balancing And Content Analysis

    Because this data request is only sent out after a connection is established, the Px series application switch must first act as a proxy for the server by acting as the endpoint of the TCP/IP connection from the client.
  • Page 15 IP address that is part of a proxy pool inside the application switch. After a connection is established between the application switch and the real server, the application switch forwards the buffered data to the server. The server sends any response to the application switch.

  • Page 16: Port Rewrite

    Getting Started on Load Balancing Configuration To successfully configure the Px series application switch to perform load balancing operations, you must consider the following: • Do you want to use full NAT or server-only NAT mode? For more information on NAT, see Chapter 6.
  • Page 17 — If the virtual service is layer 4, assign a server group to it. — If the virtual service is layer 7, create the appropriate domains and pattern-rules, and assign server groups to the pattern-rules.

Installing the SummitPx1 Application Switch The application switch can be mounted in a rack or placed free-standing on a tabletop. Rack Mounting Caution: The rack mount kits must not be used to suspend the switch from under a table or desk, or to attach to a wall.

  • Page 23: Free-Standing

    Up to four SummitPx1 application switches can be placed on top of one another. Powering On the SummitPx1 To turn on power to the SummitPx1 application switch, connect the AC power cable to the switch and then to the wall outlet.

  • Page 24: Setting Up Console Communication

    If the application switch passes the POST, the MGMT LED blinks at a slow rate (1 blink per second). If the application switch fails the POST, the MGMT LED shows a solid yellow light. Setting Up Console Communication To manage the application switch locally, you must connect to the management console to configure the switch’s Ethernet management port using a serial connection.

  • Page 25: Configuring Switch Ip Parameters

    Configuring Switch IP Parameters To manage the application switch by way of a Telnet connection to the Gigabit Ethernet port, you must first configure the switch IP parameters. To manually configure the IP settings, follow these steps: 1 Connect a terminal or workstation running terminal-emulation software to the serial management (console) port.

  • Page 44: Ssh2 Client Functions On The Switch

    SSH2 Client Functions on the Switch In ExtremeWare version 6.2.1 or later, an Extreme Networks switch can function as an SSH2 client. This means you can connect from the switch to a remote device running an SSH2 server, and send commands to that device. You can also use SCP2 to transfer files to and from the remote device.
