Interface Status
You can view status details for any interface through interface status windows, which are associated with each particular line card.
This chapter contains the following information:

Interfaces and Related Technology-Specific Windows
Interfaces and Related Technology-Specific Windows
Interfaces on line cards can support multiple technologies. Status windows are technology-specific. For example, a DS-3 interface supports two technologies:
•
•
Therefore, if you want to view the status of a DS-3 interface, you need to view two windows:
•
•
This same process is applicable to DS-3, ATM, or Ethernet interfaces. The following table outlines which technology-specific status windows apply to each interface type.

Generic Interface Status Window—Detailed Description
The Generic Interface Status tab has three areas:
•
•
•
Interface Details
The Interface Details area displays the following fields:
Type—Type of interface.
Description—Information about the interface. Generally contains the product name and the version of the interface hardware or software.
Operational Status—Current operational status of the interface. Possible values are as follows:
•
•
•
•
•
•
•
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:
Interface Last Change—Value of system up time at the time the interface entered its current operational state. If the current state was entered prior to the last re-initialization of the local network management subsystem, then this object contains a zero value.
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 units of 1,000,000 bits per second.
Maximum Transmission Unit—Size of the largest packet which can be sent or received on the interface, specified in octets.
SONET Interface Status
The SONET Interface Status section covers the following areas:
•
•
Viewing the SONET Interface Status Window
To view the SONET status window for any type of interface, proceed as follows:

Line Coding—Type of line coding used in the interface. Can be B3ZS for electrical SONET signals or NRZ for optical SONET signals.
Line Type—Line type for the interface. Can be short range single mode, long range single mode, or multi-mode for fiber interfaces; for electrical interfaces, it can be coax or UTP; and for all other line types it will be other.
Valid Intervals—Number of previous intervals for which valid data is stored.
Time Elapsed—Time elapsed (in seconds) after the start of the current error-measurement period. Includes partial seconds.
Circuit ID—Transmission vendor's circuit identifier.
Section
The Section tab appears as follows.
