Chapter 9 Interface Status
Generic Interface Status
Generic Interface Status Window—Detailed Description
The Generic Interface Status tab has three areas: Interface Details, Last Change Details, and
Transmission Details.
Interface Details
The Interface Details area displays the following fields:
Type—Type of interface.
Description—Information about the interface. Generally contains the interface name.
Operational Status—Current operational status of the interface. Possible values are as follows:
• Up—Ready to pass packets (if admin status is changed to up, then operational status should change
to up if the interface is ready to transmit and receive network traffic)
• Down—If admin status is down, then operational status should be down
• Testing—In test mode, no operational packets can be passed
• Unknown—Status can not be determined for some reason
• Dormant—Interface is waiting for external actions
• NotPresent—Some component is missing, typically hardware
• LowerLayerDown—Down due to state of lower layer interface
Physical Address—Interface’s address at its protocol sub-layer. For example, an 802.x interface
normally contains a MAC address. For interfaces that do not have such an address (such as a serial line),
this object should contain an octet string of zero length.
Keep Alive—Displays whether keepalives are enabled or not on this interface.
Line Protocol—Displays whether the line protocol is up or not.
Connector Present—If the interface sublayer has a physical connector, this object has the value true.
Otherwise, this value will be false.
Last Change Details
The Last Change Details area displays the following fields:
Current State Duration—This value indicates the time duration since the last interface operational status
was changed. This, however, is not applicable to the SRP interface side objects and the VLAN
sub-interface objects.
Reason for Last Change—Reason for the interface’s last status change.
Transmission Details
The Transmission Details area displays the following fields:
Speed—(in bps) Estimate of the interface’s current bandwidth in bits per second.
High Speed—Estimate of the interface’s current bandwidth in gigabits per second.
Maximum Transmission Unit—Size of the largest packet which can be sent or received on the interface,
specified in octets.
