    Table 2: Fields on the Configure Physical Interface Page
    Field Description
    Basic Information

    Interface Name

    Enter a name containing up to 63 characters without spaces.

    The name must begin with an alphanumeric character and can include colons, periods, dashes, and underscores.

    Description

    Enter a description of the physical interface.

    Ensure that the description contains useful information that is helpful to administrators.

    MTU

    Enter the Maximum Transmission Unit (MTU) size.

    MTU is the largest packet or frame size specified in bytes or octets that can be sent in a packet-based or frame-based network. TCP uses MTU to determine the maximum size of each packet in any transmission. The valid range is between 256 and 9192.

    Enabled

    Enable this option to activate VLAN tagging for the physical interface.

    VLAN Tagging Type

    Select whether you want the interface to receive and forward dingle tag frames, flexible dual-tag frames, or a mixture of untagged single-tag and dual-tag frames.

    If you change the VLAN tagging type, you must update the logical units of this interface.

    Native-VLAN ID

    Enter the VLAN identifier to associate with the untagged packets received on the physical interface of a trunk mode interface.

    Ethernet Config

    MAC address

    Enter the MAC address of the physical interface.

    Storm Control Profile Name

    Enter a storm control profile on a switch or router.

    Storm control is used to prevent network outages that are caused by broadcast traffic storms.

    Aggregate ID

    Enter the aggregated Ethernet interface ID.

    Port Speed

    Enter the port speed for the interface.

    Port speed is the maximum amount of data that the line card transmits through a port in one second.

    Flow Control

    Enable this option to regulate the flow of packets from the device to the remote side of the connection.

    VLAN Interface Mode

    Determine whether the interface accepts or discards packets based on VLAN tags.

    Select one of the following options:

    • None to accept both untagged and tagged packets.

    • TRUNK for only tagged packets.

    • ACCESS for only untagged packets

    Access VLAN

    Enter the VLAN ID to which the interface that accepts untagged packets belongs.

    Trunk VLANs

    Enter the VLAN ID to which the interface that accepts tagged packets belongs.

    Gratuitous-ARP Reply

    Enable this option to process ARP updates received through gratuitous ARP reply messages.

    Gratuitous-ARP No reply

    Enable this option to prevent the interface from responding to gratuitous ARP requests.

    Hold Time Up

    Select the hold time to use when an interface transitions from down to up.

    Hold Time Down

    Select the hold time to use when an interface transitions from up to down.
