Perform Device Configuration

Create a network policy and Device Template.

Under Device Configuration, you can choose to override settings made under Common Settings in a network policy. The Switch Template Override feature allows customers 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 device configuration will be inherited by the network policy common settings.

Note

If this is a switch stack, repeat this task for each device in the stack.

Navigate to Configure > Network Polices > the existing network policy > Switching > Switch Templates and select the template for the device model.
Ensure that Enable Override Policy Common Settings is set to ON to make any changes to device configuration.
For STP Configuration, see Configure STP Settings.
For IGMP Settings, toggle to On and make the following selections:
- 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.
For MAC Locking Settings, select to control the forwarding database for learned MAC address entries on a port.

Note
MAC Locking must also be enabled on a per-port basis.
For Extreme Loop Recovery Protocol Settings, select to configure ELRP client periodic packet transmission for VLAN(s) 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
ELRP must also be enabled within the switch template.
For DHCP Snooping Settings, toggle to On, and make the following selection:
- Drop Rogue DHCP Packets Action: Ports configured as Trusted will not apply drop action.
Note
If VLAN attributes has enabled DHCP Snooping settings, then the VLAN attributes will override the switch template.
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.
For PSE Settings, toggle to On to configure maximum power thresholds to generate alerts to ExtremeCloud IQ about exceeding maximum power levels.
For Management Interface Settings (Switch Engine devices only), select one of the following options:
- 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.

Proceed to Port Configuration.
