Interfaces on port adapters can support multiple technologies. Status windows are technology-specific. For example, a DS-3 interface supports two technologies:
Generic
DS-3
Therefore, if you want to view the status of a DS-3 interface, you need to view two windows:
Generic Interface Status window
DS-3 Interface Status window
This applies to DS-3, ATM, or Ethernet interfaces as well. The following table lists the technology-specific status windows that apply to each interface type.
To view the Generic Interface Status window for any type of interface:
Step 1 Right-click the selected port adapter, then choose CERM Management > Physical > Interface > Generic > Status.
Figure 8-1: Generic Interface Status Window
Step 2 Choose the chassis, module, and interface from the list boxes on the left side of the window. The corresponding details for the selected module appear.
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:
Up: Ready to pass packets (if admin status is changed to up, then operational status should also 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 cannot be determined.
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 address at its protocol sublayer; 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—Indicates whether or not keep alives are enabled 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 value is True. Otherwise, the value is False.
The Last Change Details area displays the following fields:
Interface Last Change—Value of system uptime 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, then this object contains a zero value.
Reason for Last Change—Reason for the last interface status change.
To view the SONET status window for any type of interface:
Step 1 Right-click the selected port adapter, then choose CERM Management > Physical > Interface > SONET > Status.
Figure 8-2: SONET Interface Status (Medium Tab)
Step 2 Choose the chassis, module, and SONET interface from the list boxes on the left side of the window. The corresponding details for the selected interface appear on the tabs on the right side of the window.
Type—Indicates whether the signal used across this interface is SONET or SDH.
Line Coding—Type of line coding used in the interface. It can be B3ZS for electrical SONET signals or NRZ for optical SONET signals.
Line Type—Line type for the interface. It can be short-range single mode, long-range single mode, or multimode for fiber interfaces; for electrical interfaces, it can be coax or UTP; and for all other line types it is "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.
To view the ATM Interface Status window for any type of interface:
Step 1 Right-click the selected port adapter, then choose CERM Management > Physical > Interface > ATM > Status. The ATM Interface Status window appears as shown in Figure 8-7.
Figure 8-7: ATM Interface Status Window
Step 2 Choose the chassis, module, and ATM interface from the list boxes on the left side of the window. The corresponding details for the selected interface appear on the tab on the right side of the window.
The ATM Transmit Status pane allows you to view and configure the following attribute:
Bit Rate Type—Service category to which the row applies.
Available Cell Rate—Available cell rate for traffic sent out of the interface for this service category.
Allocated Cell Rate—Allocated cell rate for traffic sent out of the interface for this service category.
LED Status—Transmit LED color for this interface.
Maximum Cell Transfer Delay—Maximum cell transfer delay for the service category. Applies only to cbr and vbr-rt service categories. The units of this object are in microseconds.
Peak-to-Peak Cell Delay Variation—Default peak-to-peak cell delay variation time (in microseconds) for this service category. Applies only to cbr and vbr-rt service categories.
Cell Loss Ratio—Default cell loss ratio for this service category (for CLP=0 cells only). The units of this object are negative powers of ten; so an object value of 8 equals 10**(-8).
The Action area contains one button: Show Connections. This button provides IOS information about the state of the current connections on the selected interface. When you click the Show Connections button, a separate window appears, displaying the status of all connections on the selected interface.
To view the DS-3 interface status window for any type of interface:
Step 1 Right-click the selected port adapter, then choose CERM Management > Physical > Interface > DS-3 > Status.
Figure 8-8: DS-3 Interface Status Window
Step 2 Choose the chassis, module, and DS-3 interface from the list boxes on the left side of the window. The corresponding details for the selected interface appear on the tab on the right side of the window.
