Switch Ports displays the current Ethernet interface link settings for the system. If needed, the rate for each interface can be set manually to establish a reliable connection. The MTU size of the WAN interface can be adjusted to reduce the effects of large data packet on media data.

  1. Choose Network > Switch Ports.

  2. Configure settings using the information in the following table as a guide.

    Switch Ports Configuration Parameters

    ItemDescription

    Link Rate Settings

    Displays the current Port and Mode settings for the LAN and WAN interfaces.

    PortLists ports on the system and WAN Ethernet information.
    Mode

    Sets the link rate of an interface:

    Autonegotiate (default)

    10Base T-HD

    10Base T-FD

    100Base T-HD

    100Base T-FD

    1000Base T-FD

    Gigabit copper link (RJ45) rate settings:

    Autonegotiate (default)

    10Base T-HD

    10Base T-FD

    100Base T-HD

    100Base T-FD

    1000Base T-FD SFP link rate settings:

    1000 Autoneg

    1000FD No-neg

    100FD No-neg

    The default setting is autonegotiate. When connecting a device to the system that cannot be hard coded, leave these ports set to autonegotiate.

    Note: The link rate of an interface can be set to static values, and it is recommended to statically set the values on both the system and devices connecting to any port when applicable. Inconsistent rates may cause “flutter,” leading to intermittent voice outages.

    WAN Active Media

    Displays the current active connector of the WAN interfaces.

    Only one of SFP or RJ45 can be active at a time for each WAN interface. If SFP is active then RJ45 is deactivated. For each enabled WAN interface, the status will read “SFP Port”, “RJ45 Port”, or “Inactive” (if neither are connected).

    Detailed Link Rate Information

    Lists detailed Link Rate Information. If the negotiated rates change intermittently or the link is reported as no link or down, the link rate may need to be set manually. Both sides of the link must be set to the same rate. Inconsistent rates may cause “flutter,” leading to intermittent voice outages.

    Note: When the link rate is set manually, ensure that the device at the far end of the connection can communicate at the desired rate. Incompatible rates can cause a loss of communication with the system.

    Set LAN MTU size/ Set Primary WAN MTU size/ Set Secondary WAN MTU size

    Sets the WAN MTU size on some EdgeMarc platforms to reduce the latency that is introduced when large data packets are sent over a slow link. The default setting is 1500 bytes for static IP addresses.

    PPPoE links negotiate the value automatically although the value can be overridden using this field. If the WAN Upstream Bandwidth is less than 256 Kbps, the MTU size is automatically reduced to 800 bytes. The WAN interface must have an IPv4 address assigned.

    Note: When the link rate is set manually, ensure that the device at the far end of the connection can communicate at the desired rate. Incompatible rates can cause a loss of communication with the system.

  3. In the Mode column, choose from the following rates for each Ethernet link, or choose Autonegotiate:

    • 10Base T-HD

    • 10Base T-FD

    • 100Base T-HD

    • 100Base T-FD

    • 1000Base T-FD

  4. In the Set WAN MTU size field, adjust the WAN MTU size to reduce latency when large data packets are sent over a slow link. Default is 1500 bytes for static IP addresses.
