Interface tab

The Interface tab shows the basic configuration and status of a port.

To view the Interface tab, follow this procedure:


Step Action

1

Select the port to edit from the Device View. Select Edit, Port from the menu. The Port screen opens with the Interface tab displayed.

To continue, go to:

Interface tab items

The following table describes the Interface tab fields.

Interface tab fields

Field Description
Index A unique value assigned to each interface. The value ranges between 1 and 64 standalone. On stack, the index value of the first port of the second unit is 65. The maximum value is 512.
Name Use this field to enter an optional name for the port.
Descr The type of switch and number of ports.
Type The media type of this interface.
Mtu The size of the largest packet, in octets, that can be sent or received on the interface.
PhysAddress The MAC address assigned to a particular interface.
AdminStatus

The current administrative state of the interface, which can be one of the following:

  • up
  • down

When a managed system is initialized, all interfaces start with AdminStatus in the down state. AdminStatus changes to the up state (or remains in the down state) as a result of either management action or the configuration information available to the managed system.

OperStatus

The current operational state of the interface, which can be one of the following:

  • up
  • down
  • testing

If AdminStatus is up, then OperStatus is also up if the interface is ready to transmit and receive network traffic. If AdminStatus is down, then OperStatus is also down. It remains in the down state if and only if there is a fault that prevents it from going to the up state. The testing state indicates that no operational packets can be passed.

LastChange The value of sysUpTime at the time the interface entered its current operational state. If the current state was entered prior to the last reinitialization of the local network management subsystem, the value is zero.
LinkTrap Indicates whether linkUp/linkDown traps are generated for this interface. By default, this object has the value enabled for interfaces that do not operate on top of any other interface (as defined in the ifStackTable).
AutoNegotiate Indicates whether this port is enabled for autonegotiation or not.
AdminDuplex Sets the administrative duplex mode of the port (half or full).
OperDuplex Shows the current administrative duplex mode of the port (half or full).
AdminSpeed Set the port speed.
OperSpeed The current operating speed of the port.
AutoNegotiation
Capability

Specifies the port speed and duplex capabilities that hardware can actually support on a port, and which can be advertised by the port using auto-negotiation. Bit 7 tells if a port supports pause frame capabilities (for full-duplex links) as a part of the advertisement.

bit 0 - 10 half duplex advertisements

bit 1 - 10 full duplex advertisements

bit 2 - 100 half duplex advertisements

bit 3 - 100 full duplex advertisements

bit 4 - 1000 half duplex advertisements

bit 5 - 1000 full duplex advertisements

bit 6 - PAUSE frame support advertisements

bit 7 - Asymmetric PAUSE frame support advertisements

If auto-negotiation is not supported by the port hardware, then all bits reflect a value of zero.

AutoNegotiation
Advertisements

Specifies the port speed and duplex abilities to be advertised during link negotiation.

  • 10Half: 10 half duplex advertised
  • 10Full: 10 full duplex advertised
  • 100Half: 100 half duplex advertised
  • 100Full: 100 full duplex advertised
  • 1000Half: 1000 half duplex advertised
  • 1000Full: 1000 full duplex advertised
  • PauseFrame: PAUSE frame support advertised.
  • AsymPauseFrame: Asymmetric PAUSE frame support advertised.

The abilities specified in this object are only used when auto-negotiation is enabled on the port. If all bits in this object are disabled, and auto-negotiation is enabled on the port, then the physical link process on the port is disabled.

WanMode Set the area network type for a 10 GE port.
  • none
  • wan
  • lan
MltId The multilink trunk to which the port is assigned (if any).
IsPortShared Displays if the selected port is a shared port or not.
PortActive
Component
Displays the active component of shared ports.
