Status information is available for managed interfaces and connections on the device. Using the status indicators the corresponding windows provides, it is possible to determine if particular objects require attention.
The Status chapter contains the following information:
Interfaces on line cards can support multiple technologies. Status windows are technology-specific. For example, an ATM interface supports multiple technologies: ATM, SONET, and IP. Therefore, if you wish to view the status of an ATM interface, you must view the ATM Interface Status window, the SONET Status window, in addition to the Generic Interface Status window. Note that there is not a separate IP-specific status window.
The following table outlines which technology-specific status windows apply to each interface type.

To view the Generic Interface Status window for any type of interface, proceed as follows:
Step 1 Right-click (on a relevant object icon in the Map Viewer window or from an object pick list) and choose Cisco 8500 Series Manager > Status > (Interface >) Generic. Refer to "EM Windows" for information on which objects allow you to launch the Interface Status window.
The Interface Status window appears.
Figure 9-1 Interface Status Window
Step 2 Select a chassis from the Chassis list box at left of the window, select a module from the Module list box, then select an interface from the Interface list box.
Status information for the interface selected displays. Data in the Interface Details area displays the following:
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:
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 determination is not possible 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 yes. Otherwise, this value will be no
The Last Change Details area displays the following:
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 (that is, the SNMP Agent on the Cisco Catalyst 8500 family router), then this object contains a zero value.
Reason for Last Change—Reason for the interface's last status change
The Transmission Details area displays the following:
Speed—(in bps) Estimate of the interface's current bandwidth in bits per second. Speed is used for interfaces less than 4,294,967,295 bits per second. High Speed should be used for interfaces above this value.
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.
Step 3 Review the data on each tab as necessary.
Step 4 Choose File > Close to close the Interface Status window.
If the EM provides additional technology-specific status information for the interface you reviewed, you may proceed to one of the following sections:
To view the ATM Interface Status window for ATM, IP, or SONET interfaces, proceed as follows:
Step 1 Right-click (on a relevant object icon in the Map Viewer window or from an object pick list) and choose Cisco 8500 Series Manager > Status > (Interface >) ATM. Refer to "EM Windows" for information on which objects allow you to launch the ATM Interface Status window.

SONET Interface Status
The presentation of SONET interface status information provides easy to decipher color indicators for several of the values. Possible color indicators which may display are green (OK, no errors), red (errors), or yellow (suppressed errors).
Error suppression occurs when an error in one field prevents data retrieval for another field. The following table lists the SONET status attribute suppression behavior rules for what happens when certain conditions arise. Examples of how to read the table and how the data the table displays related to the status color indicators on the Section, Line, Path, and Virtual Tributary tabs of the SONET Interface Status window follow.

"S" indicates that the attribute value is suppressed and the color indicator will be yellow, and "—" indicates that the attribute value is not suppressed
For example, the Rule 1 column indicates that if item (4), Line Alarm Indication Signal, is asserted, that is, the color indicator is red, then items (5), (7), (8), (9), (10), and (11) are suppressed, that is, the color indicator is yellow. The fields are yellow because the data cannot be retrieved due to the indication of a failure by the field that is red.
