Configure a Switch

As an administrator, you can make changes to your switch configuration. Use this procedure to configure an ExtremeSwitch or an Extended Edge Switch

Some use cases include:

• Deploying a cloud-enabled ExtremeSwitch
• Deploying a new collection of cloud-enabled APs and switches
• Deploying a new service that uses a new VLAN
• Enabling LAG to an AP
• Diagnosing and correcting a connectivity issue
• Rebooting a switch
• Cloning a configuration for an RMA replacement

When a configuration change is made, it gets pushed to the switch the next time the switch checks in with ExtremeCloud. If the switch does not receive a response from ExtremeCloud, the switch reboots and loads the previous working configuration that is stored on the switch.

Note

Most switch management is done using the graphical user interface (GUI). ExtremeCloud also offers a CLI mode option.

To configure a switch:

1. Select Configure > Devices > Switches from the menu.
2. Select a switch from the list.
   Details about the switch are displayed. (The PoE budget can be viewed in the Hardware pane.)
3. Select View Configuration.
4. Edit the fields:
   

   Switch Configuration

   

   Name	(Required) Specify a unique name.
   Ports	Enable the check box to perform bulk configuration of ports, or select a single port from the list to configure.
   Set Selected Ports	Select one or more ports from the list,. Then, one at a time, set the Admin State, Port Function, and PoE options to On or Off. Select Apply after each selection.

5. Select New LAG. Edit the fields (the dialog displays the options when you select a master port) and select Save Master Port. You can either create or delete LAG ports. Link aggregation allows multiple physical ports to be aggregated into one logical port, or link aggregation group (LAG), which provides increased bandwidth and link redundancy.

   Important

   When configuring a LAG port for use by an ExtremeCloud-enabled access point, enable link aggregation on the access point first. If you do not do this, the AP can become isolated from the network. If the AP becomes isolated by the switch LAG port configuration, disable link aggregation on the switch ports used by the AP to allow the AP to join the network again. LAG can then be enabled on the AP, which takes one minute to update the configuration. Approximately two minutes later, LAG can be enabled on the corresponding switch ports.

   

   LAG Configuration

   

   Choose a Master Port

   Specify the master port for the LAG configuration on this switch by selecting from the drop-down list. Then drag and drop the ports you want into the Master Port pane.

6. Select Advanced. Select the options you want, and select Close.
   

   Note

   LLDP is automatically enabled on the switch and is not configurable. The RMA button is used for RMA replacements. For more information, see RMA Replacement Process.

   

   Switch Advanced Settings

   

   Bridge Priority	By configuring the STPD (Spanning Tree Domain) bridge priority, you change the likelihood of the switch becoming the root bridge. The lower the numerical value of the priority, the more likely the switch is the root bridge. Multiples of 4,096 are used to determine the bridge priority, per the 802.1D-2004 standard. Default: Depends on the switch model. Important You should not configure this STP parameter unless you have considerable knowledge and experience with STP. The default parameter is adequate for most networks.
   IGMP Snooping	Enable snooping of Internet Group Management Protocol (IGMP) to provide a method for intelligently forwarding multicast packets within a Layer 2 broadcast domain. By snooping the IGMP registration information, the device forms a distribution list that determines which end stations receive packets with a specific multicast address. Layer 2 switches listen for IGMP messages and build mapping tables and associated forwarding filters. IGMP snooping also reduces IGMP protocol traffic. Default: Disabled
   LED Status	Select On to make the LEDs flash on the switch. Can be used for identifying a switch in a DC or a rack or for testing the communication between the switch and cloud management. Stays on until turned off. Default: Off
   Change to CLI-Mode	Manage the switch in CLI mode directly from the cloud user interface. Review the CLI-Mode documentation before selecting this option.
   Reboot	Restarts the switch.
   RMA	Lets you replace this device with a new device and automatically assign the configuration to the new device.
   Clone From	Use this option with an RMA switch replacement. This options lets you clone the configuration from the old switch to the new replacement switch.

7. If needed, configure STP, VLANs, and SNMP by selecting the corresponding links in the Advanced Settings dialog.
8. In the Advanced Settings dialog, select Close.
9. On the Configure Switch page, select Save.
