Configuring VLANs

Virtual LANs and VLAN tables are configured using options from Cisco ATM Administrator GUI (csadmin). You can access options from the Cisco ATM Administrator GUI to dynamically configure your system for ATM communications. In general, the tasks to configure VLANs are:

Step 1 Plan your network. Determine the type(s) of VLANs you'll be configuring (IPATM and/or LANE). This chapter contains details for setting up each of these types. For information about VLAN parameters that must be considered when setting up virtual LAN types, see Chapter 4, "Virtual LAN Considerations."

Step 2 For IPATM VLANs, commonly referred to as Logical IP Subnets (LIS), find out the location of one ATM ARP Server for each VLAN. Determine how many VLANs you'll be initializing and the associated VLAN numbers and IP address assignments for each. Refer to "Adding a New VLAN" on page 3-13 and "Quick Install for IPATM" on page 3-7 for detailed information on configuring a new IPATM VLAN.

Step 3 For LANE VLANs, commonly referred to as emulated LANs (ELAN), find out the location of the LAN Emulation Configuration Server for each VLAN. Determine how many VLANs you'll be initializing and the associated VLAN numbers assigned for each. Refer to "Adding a New VLAN" on page 3-13 and "Quick Install for LAN Emulation" on page 3-7 for detailed information on configuring a new LANE VLAN.

Step 4 Initialize each new VLAN that will terminate on the host by adding it to your system. See "Adding a New VLAN" on page 3-13 for details.

Step 5 Configure each new VLAN using the default VLAN parameters. See "Configuring a VLAN" on page 5-22 for details. See Chapter 6, "Understanding VLAN Configuration File Syntax" for details on configuration file syntax.

Step 6 For IPATM (or LIS) VLANs, create the appropriate VLAN tables by making entries into the host's active ARP server table. See "Viewing and Modifying the Server ARP Table" on page 5-47 for details.

Step 7 Set up any permanent virtual circuit (PVC) connections. See "Adding and Removing PVC Entries" on page 5-57 for details on setting up PVCs using the Cisco ATM Administrator.

Step 8 Save the configuration information for each host. See "Saving VLAN Settings" on page 5-60 for details.

Step 9 Repeat the initialize, configure, create, set up, and save processes for each Cisco ATM PCI Adapter host.

You can dynamically configure a virtual LAN by selecting the VLAN menu option from the Cisco ATM Administrator Main Menu (Figure 5-1).

To dynamically configure a virtual LAN:

Step 1 Select the VLAN option from the Cisco ATM Administrator Main Menu (Figure 5-1).

The Virtual LAN Options window appears (Figure 5-21). Each virtual LAN is configured and maintained through this window.

Step 2 Choose a virtual LAN number.

Note A virtual LAN number is the unique identifier by which the virtual LAN is identified by the Cisco ATM Administrator. Each VLAN must have a unique identifier number ranging from 0-255. You can define up to eight VLANs using any of the 256 numbers. Any subsequent selection of the buttons (located at the bottom of the Virtual LAN Options window) affects only the specified VLAN number.

Figure 5-21 : Virtual LAN Options Window

nm1840.gif


Configuring a VLAN

You use the configuration features of the Cisco ATM Administrator to set and modify VLAN parameters. Parameters are used to store information such as the external server for IP over ATM protocol. You can modify VLAN configuration parameters at any time after adding the virtual LAN to the system.

To configure a virtual LAN, or modify an existing VLAN configuration, after it had been initialized:

Step 1 Choose the VLAN option from the Main Menu (Figure 5-1).

The Virtual LAN Options window appears (Figure 5-21).

Step 2 Select the number of an existing VLAN on the Virtual LAN Options window (Figure 5-21). If you do not know your VLAN's identifier number, see "Deleting an Existing VLAN" on page 3-15 for instructions on how to obtain it.

Step 3 Select the Configuration option.

One of theVirtual LAN Configuration windows appears (Figure 5-22 or Figure 5-24).

Depending on the VLAN type you selected when the VLAN was added to the system, the VLAN Configuration window that is presented will be one of the following:

  • IP-ATM (LIS)

  • LAN Emulation (ELAN)

Refer to the appropriate subsection for information about the fields available for the VLAN type you are configuring or modifying. To set configuration parameters for a VLAN:

Step 4 Enter the values into the appropriate VLAN Configuration window fields. Then select Apply.


Configuring an IP Over ATM VLAN

This section describes how to configure an IP over ATM VLAN. The acronyms IPATM (IP over ATM) and/or LIS (Logical IP Subnet) are used when referring to IP over ATM Logical Subnets. See "Adding a New VLAN" on page 3-13 for instructions on creating and initializing an IPATM VLAN.

To configure an IPATM VLAN, after it has been initialized:

Step 1 Enter a VLAN number that corresponds to an IPATM VLAN in the Virtual LAN Options window (Figure 5-21).

Step 2 Choose Configuration from the Virtual LAN Options window.

The Virtual LAN Configuration - IPATM window appears (Figure 5-22).

Figure 5-22 : Virtual LAN Configuration Window - IPATM

nm1841.gif

To set configuration parameters for an IPATM VLAN:

Step 3 Enter the values into the appropriate VLAN Configuration window fields and select Apply.

The fields on the Virtual LAN Configuration - IPATM window and their meanings are:

  • VLAN Number---[read-only] Displays the VLAN number to identify the logical subnet the data relates to. This is the number you set when you initialized the VLAN.

  • VLAN State---[read-only] Displays one of the following values:

    • Operational---The VLAN is functioning properly.

    • Shutdown---The VLAN has not been configured and/or started.

    • Network Prefix Pending---The local workstation is in the process of getting a fully qualified ATM address from the switch (via the ILMI protocol).

  • VCC Timeout---Enter a value for the amount of time to wait before removing an inactive VCC. The Cisco ATM software will delete a VCC entry from the connection table if no traffic is transferred over the VC within this period. This value is expressed in seconds.

  • Complete Timeout---Enter a value for the amount of time to wait before terminating an inactive connection to a client. After the Cisco ATM software has resolved an ATM address on this VLAN, if no traffic is being transferred for this period, the entry will be deleted from the ARP table. This value determines how often the ARP information is validated to assure accurate information. This value is expressed in seconds.

  • Server Inactive Timeout---Enter a value for the amount of time to wait before terminating an inactive connection to the VLAN's ARP Server. The Cisco ATM software will terminate the connection to the ARP Server if connection is inactive for this period. This value is expressed in seconds.

  • Incomplete Timeout---Enter a value for the amount of time to wait in order to resolve an ATM address. When Cisco ATM software is in the process of resolving an ATM address on this VLAN, if the ATM address remains unresolved for this period, the entry will be deleted from the ARP table. This value is expressed in seconds.

  • Maximum MTU Size---Enter the maximum AAL5 SDU size of a data frame that the LEC wishes to send. This value is expressed in bytes and should not exceed 9180 bytes.

  • Peak Data Rate---Enter the maximum rate at which cells are allowed to transfer over the connection. This entry is expressed in megabits per second.

  • Average Data Rate---Enter the average rate at which cells are allowed to transfer over the connection. This value must be below the peak rate and is expressed in megabits per second.

  • Burst Cells at Peak Rate---Enter the maximum number of cells allowed to transfer over the connection at the peak rate. This entry is expressed in number of cells.

  • IP Address---Enter the IP address of the client. The value is expressed either as the explicit dotted decimal notation, or as a host name (resolved in the hosts file or through a domain name server). A unique IP address is required for each VLAN.

  • ATM Address---[read-only] Displays the ATM address of the client for this VLAN. The value is 20 bytes expressed in hex nibbles, each byte delimited by colons. The first 13 bytes correspond to the network prefix (identifying the target switch to which the endstation is connected) while the remaining seven bytes are used to identify the target ATM endstation.

Note Peak data rate, average data rate, burst settings, and other traffic shaping parameters recognize discrete values (136/x). Do not be alarmed if a value you enter (for example, 50) is output as a different value (for example, 45) during a test.

Locating the IPATM ARP Server

An ATM ARP Server table must be defined to collect and manipulate the information required for IP over ATM virtual LAN operation. The ARP Server Information window controls how the connection to the ARP Server is set up. All other endstations can then connect to the ARP server to identify the ATM addresses for other nodes on the same VLAN. The ATM ARP server is usually located on the Cisco router.

At this time, you are only establishing an initial ARP Server connection, not modifying the ARP Server table. For more connection information, see "Viewing and Modifying VLAN Tables" on page 5-40 and "Viewing and Modifying the Server ARP Table" on page 5-47.

To choose an initial location for the server ARP table, or to move the server ARP table:

Do one of the following:

  • Choose Servers from the Virtual LAN Options window (Figure 5-21), or

  • Choose ARP Server from the Virtual LAN Configuration - IPATM window (Figure 5-22).

Choosing either of these options displays the ARP Server Information window (Figure 5-23).

fig_2.gif

Caution If you wish to save your configuration values, be sure to choose Save from the Main Menu (Figure 5-1) before exiting the Cisco ATM Administrator.


Refreshing the LANE VLAN Configuration Window

To update the values on the screen, or to obtain the current VLAN state:

Choose Refresh from the VLAN Configuration - LAN Emulation window (Figure 5-24).


Viewing and Modifying VLAN Tables

Note VLAN Tables are used only in IP over ATM configurations. Table features are disabled when configuring LAN Emulation VLANs.

VLAN tables contain connection information needed in ATM configurations. You set up and monitor connection statistics using VLAN tables. Each time a connection is established between ATM endstations on a particular VLAN, an entry is added to the appropriate connection table.

To get access to the various tables needed for your VLAN configuration:

Step 1 Select Tables from the Virtual LAN Options window (Figure 5-21).

The VLAN Tables Menu window appears (Figure 5-26).

Figure 5-26 : VLAN Tables Menu Window

nm1845.gif

The fields on the VLAN Tables Menu and their meanings are:

  • VLAN Number---Displays the current VLAN number.

  • Client Arp Table---Accesses the Client ARP Table required for IPATM protocol connections. The ATM addresses associated with each IP address are dynamically or statically stored in the client ARP table.

  • Server Arp Table---Required for IPATM VLAN configurations. Stores and monitors the target (IP address) and the host (ATM address of the host adapter) information. Can be used to query and update the client ARP table.

  • Connection Table---Used to monitor connection status between ATM endstations and a particular VLAN. Both SVC and PVC connection statistics are collected. (IP over ATM and LAN Emulation protocols are usually connected as SVCs that are dynamically opened and closed. PVC connections must be manually opened and closed.)

  • ARP Connection Table---Contains accumulated connection data from Client and Server ARP Tables and from the Connection Table.

  • PVC Entries---Used to set up PVCs. Permanent Virtual Circuits must be established and disconnected manually between ATM endstations and each connected PVC VLAN.

Step 2 Click on the field (Figure 5-26) for the appropriate VLAN table.

The corresponding table opens.

See Chapter 4, "Virtual LAN Considerations," for more information related to what tables are necessary for your particular network configuration.
