Configuring Spanning Tree Protocols on EX Series Switches (J-Web Procedure)

Note

This topic applies only to the J-Web Application package.

EX Series switches provide Layer 2 loop prevention through Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), Multiple Spanning Tree Protocol (MSTP), and VLAN Spanning Tree Protocol (VSTP). You can configure STP, RSTP, and MSTP by using the J-Web interface. You can configure bridge protocol data unit (BPDU) protection on interfaces to prevent them from receiving BPDUs that could result in STP misconfigurations, which could lead to network outages.

Note

In EX4300 switches, you can configure STP only by enabling RSTP and forcing it to act as STP. You need to select the Force STP check box from the RSTP configuration page.

To configure STP, MSTP, or RSTP for an EX Series switch by using the J-Web interface:

  1. Select Configure > Switching > Spanning Tree.

    The Spanning Tree Configuration page displays the spanning-tree protocol configuration parameters and a list of interfaces configured for each spanning-tree protocol configuration.

    Note

    After you make changes to the configuration on this page, you must commit the changes for them to take effect. To commit all changes to the active configuration, select Commit Options > Commit. See Using the Commit Options to Commit Configuration Changes for details about all commit options.

Configuring IGMP Snooping on EX Series Switches (J-Web Procedure)

Note

This topic applies only to the J-Web Application package.

IGMP snooping regulates multicast traffic in a switched network. With IGMP snooping enabled, the EX Series switch monitors the IGMP transmissions between a host (a network device) and a multicast router, keeping track of the multicast groups and associated member interfaces. The switch uses that information to make intelligent multicast-forwarding decisions and forward traffic to the intended destination interfaces.

You can configure IGMP snooping on one or more VLANs to allow the switch to examine IGMP packets and make forwarding decisions based on packet content. By default, IGMP snooping is enabled on EX Series switches.

To enable IGMP snooping and configure individual options by using the J-Web interface:

  1. Select Configure > Switching > IGMP Snooping.Note

    After you make changes to the configuration on this page, you must commit the changes for them to take effect. To commit all changes to the active configuration, select Commit Options > Commit. See Using the Commit Options to Commit Configuration Changes for details about all commit options.

  2. Click one of the following options:
    • Add—Creates an IGMP snooping configuration for the VLAN.

    • Edit—Modifies an IGMP snooping configuration for the VLAN.

    • Delete—Deletes a selected VLAN from the IGMP snooping configuration.

    When you are adding or editing an IGMP snooping configuration, enter information as described in Table 52.

  3. Click OK to apply changes to the configuration or click Cancel to cancel without saving changes.

To disable IGMP snooping on a VLAN, select the VLAN from the list and click Disable.

Note

The Disable option is not available for EX4300 switches.

Configuring Redundant Trunk Groups on EX Series Switches (J-Web Procedure)

Note

This topic applies only to the J-Web Application package.

A redundant trunk link provides a simple solution for network recovery when a trunk interface goes down. Traffic is routed to another trunk interface, keeping network convergence time to a minimum. You can configure redundant trunk groups (RTGs) with a primary link and a secondary link on trunk interfaces, or configure dynamic selection of the active interface. If the primary link fails, the secondary link automatically takes over without waiting for normal Spanning Tree Protocol (STP) convergence. An RTG can be created only if the following conditions are satisfied:

  • A minimum of two trunk interfaces that are not part of any RTG are available.

  • All the selected trunk interfaces to be added to the RTG have the same VLAN configuration.

  • The selected trunk interfaces are not part of a spanning-tree configuration.

To configure an RTG by using the J-Web interface:

  1. Select Configure > Switching > RTG.

    The RTG Configuration page displays a list of existing RTGs. If you select a specific RTG, the details of the selected RTG are displayed in the Details of group section.

    Note

    After you make changes to the configuration on this page, you must commit the changes for them to take effect. To commit all changes to the active configuration, select Commit Options > Commit. See Using the Commit Options to Commit Configuration Changes for details about all commit options.

  2. Click one of the following options:
    • Add—Creates an RTG.

    • Edit—Modifies an RTG.

    • Delete—Deletes an RTG.

    When you are adding or editing an RTG, enter information as described in Table 53.

  3. Click OK to apply changes to the configuration or click Cancel to cancel without saving changes.
