Interface tab

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


Note Note: 10/100BASE-TX ports may not autonegotiate correctly with older 10/100BASE-TX equipment. In some cases, the older devices can be upgraded with new firmware or driver revisions. If an upgrade does not allow autonegotiation to correctly identify the link speed and duplex settings, the settings can be manually configured for the link in question. Check the Nortel Networks Web site (www.nortelnetworks.com) for the latest compatibility information.


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.
