The Interface tab allows you to set and check basic port configuration options. Refer to the following table for item descriptions.


Item	Description
Index	A unique value assigned to each interface. The value ranges between 16 and 96.
Name	The name assigned to this interface (optional).
ifDescr	The port type of this interface.
Type	The media type of this interface.
Mtu	The size of the largest packet, in octets, that can be sent/received on the interface.
PhysAddress	The MAC address assigned to a particular interface.
AdminStatus	One of the following states: up down testing When a managed system initializes, all interfaces start with AdminStatus in the down state. As a result of either explicit management action or per configuration information retained by the managed system, AdminStatus is then changed to either the up or the testing state (or remains in the down state). The testing state indicates that no operational packets can be passed.
OperStatus	The current operational state of the interface. One of the following states: up down testing The testing state indicates that no operational packets can be passed. If AdminStatus is down, then OperStatus should be down. If AdminStatus is changed to up, then OperStatus should change to up if the interface is ready to transmit and receive network traffic. It should remain in the down state if and only if there is a fault that prevents it from going to the up state.
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 or not link Up/link Down traps should be generated for this interface.
AutoNegotiate	Indicates whether this port is enabled for auto negotiations or not (only 10/100BASE ports).
AdminDuplex	The current administrative duplex mode of the port (half or full).
OperDuplex	The current operational duplex mode of the port (half or full).
AdminSpeed	The current administrative speed of the port.
OperSpeed	The current operating speed of the port.
HighPriority	Enable High Priority for traffic ingressing the port.
MltID	The MultiLink Trunk to which the port is assigned (if any).
Locked	Indicates whether or not the port is locked. When locked, the port configuration cannot be changed. To lock or unlock a port, select Edit > Security > Port Lock.
UnknownMacDiscard	If enabled, then a packet with an unknown source MAC address is dropped on that port, and other ports then will discard any packets with this MAC address in the destination field. To enable MAC Learning, select a port and then from the menu bar select Edit > Port > Mac Learning tab.
AllowOversizeFrame	If enabled, oversized frames (up to 1750 bytes for 10/100 MB and Gigabit Ethernet interfaces) to ingress the port.
DirectBroadcastEnable	If enabled, an Isolated Routing Port (IRP) can forward directed broadcast traffic. A directed broadcast is a frame sent to the subnet broadcast address on a remmote IP subnet. By disabling or suppressing directed broadcast on an interface, all frames sent to the subnet broadcast address for a local router interface will be dropped. Disabling this function will protect host from possible denial of service (DOS) attacks. Note: This feature is enabled by default. With the feature enabled, the CPU does not receive a copy of the directed broadcast. As a result the switch does not respond to a subnet procast ping sent from a remote subnet.
Action	One of the following port-related actions: none flushMacFdb--flush MAC forwarding table for port flushArp--flush ARP table for port flushIp--flush IP route table for port flushAll--flush all tables for port triggerRipUpdate--manually update the RIP table
LastResult	Results from the last system action.
