Configure Switch Templates

You can create a switch template during the network policy creation process, or at the device level after you have a network policy in place. Device-level changes to a switch template override settings in the network policy. For more detailed information about switch use in ExtremeCloud IQ, see the ExtremeCloud IQ Universal Switch Deployment Guide.

A switch template is a visual depiction of the physical ports on a switch. Configure how ports function by assigning port types and port usage settings to the template, and then applying the template to managed switches. The following steps describe how to create a switch template inside the network policy creation workflow.

Under Device Configuration, you can choose to override settings made under Common Settings in a network policy. The Switch Template Override feature allows you to create and manage switch templates based on common settings for the SwitchEngine, ExtremeXOS, Fabric Engine, and VOSS platforms. These common settings include STP, MAC Locking, IGMP, Extreme Loop Recovery Protocol Settings (ELRP), MTU, PSE, and Management Interfaces (Switch Engine only). The default values for these settings are defined within the common switch settings for each platform type. When you create a new switch template and enable the override option, you can customize device configuration settings that will override the network policy switch common settings. If the override option is disabled, the network policy common settings inherit the device configuration.

To make changes to a switch template at the device level, go to Manage > Devices and select a device name.

Use this task to configure a switch template.

  1. Go to Configure > Common Objects > Policy > Switch Template.
  2. Select an existing switch template, and then select Edit, or select Add and select the switch model from the list.
  3. Type a Name for the template.
  4. To make changes to device configuration (Switch Engine only), enable Override Policy Common Settings.
  5. For STP Configuration, enable STP (Spanning Tree Protocol) and configure the settings.

    See Configure Switch STP Settings.

  6. For MAC Locking Settings, select to control the forwarding database for learned MAC address entries on a port.
    Note

    Note

    MAC Locking must also be enabled on a per-port basis.
  7. Enable IGMP Snooping and configure the settings.
    • Enable immediate leave: Instructs the switch to remove a multicast host from the multicast forwarding table immediately upon receipt of a leave-group-membership message.
    • Suppress redundant IGMP membership reports to optimize traffic: Suppresses redundant IGMP membership reports from multiple hosts on a subnet. The switch sends a single report to the IGMP router, reducing traffic.
  8. For Extreme Loop Recovery Protocol Settings, select to configure ELRP client periodic packet transmission for VLANs assigned to a port type to detect and prevent loops.
    This option enables an ELRP client and disables a port when a loop is detected on the applied access or trunk VLANs assigned to the port type.
    Note

    Note

    ELRP must also be enabled within the switch template.
  9. Enable DHCP Snooping, and select Enable drop rogue DHCP Packets action

    Ports configured as trusted do not apply the drop action. By default, port types configured as Trunk Port are trusted.

  10. For MTU Settings, enter a maximum transmission unit value for Ethernet interfaces.
    The MTU value determines the largest packet size that can be transmitted through your system.
  11. For PSE Settings, toggle to On to configure maximum power thresholds to generate alerts to ExtremeCloud IQ about exceeding maximum power levels.
  12. Select Enable Flow Control to manage the port data receive transmission rate.
  13. For Management Interface Settings, select one of the following options:
    • Infer from device (Dell EMC switches only): Select when the switch supplies the management interface.
    • VLAN Interface: Select when the management interface is to be supplied by the management VLAN.
      • Management VLAN: Enter the VLAN to be used by the switch.
      • Management IP Settings: Select to enable DHCP on this interface.
  14. For the Port Configuration section, see the following:
  15. For sFlow Control, see Configure an sFlow Receiver.
  16. For Supplemental CLI, see Configure Supplemental CLI.
  17. For Advanced Settings, see Configure Switch Device Template Advanced Settings.
  18. Select Save.

Continue configuring the network policy. To create a switch stack template, see Manually Create a Switch Stack.
