The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Device Reachability State—A device's reachability status represents whether Cisco EPN Manager can communicate with the device using all configured protocols.

Device Reachability State |
Description |
Troubleshooting |
Reachable |
Cisco EPN Manager can reach device using SNMP. |
— | |
Ping reachable |
Cisco EPN Manager can reach device using Ping, but not via SNMP. |
Although ICMP ping is successful, check for all possible reasons why SNMP communication is failing. Check that device SNMP credentials are the same in both the device and in Cisco EPN Manager , whether SNMP is enabled on the device, or whether the transport network is dropping SNMP packets due to reasons such as mis-configuration, etc. See Change Basic Device Properties. | |
Unreachable |
Cisco EPN Manager cannot reach device using Ping. |
Verify that physical device is operational and connected to network. | |
Unknown |
Cisco EPN Manager cannot connect to the device. |
Check the device. |
Device Admin State—A device's admin state (or status) represents the configured state of the device (for example, if an administrator has manually shut down a device, as opposed to a device being down because it is not reachable by Ping).

Description |
Troubleshooting |
Managed |
Cisco EPN Manager is actively monitoring the device. |
Not Applicable. | |
Maintenance |
Cisco EPN Manager is checking the device for reachability but is not processing traps, syslogs, or TL1 messages. |
To move a device back to managed state, see Move a Device To and From Maintenance State. | |
Unmanaged |
Cisco EPN Manager is not monitoring the device. |
In the Network Devices table, locate the device and click the "i" icon next to the data in the Last Inventory Collection Status column. The popup window will provide details and troubleshooting tips. Typical reasons for collection problems are:
If a device type is not supported, its Device Type will be Unknown. You can check if support for that device type is available from Cisco.com by choosing , then click Check for Updates. |
|
Unknown |
Cisco EPN Manager cannot connect to the device. |
Check the device. |
Port/Interface Primary States—A port/interface's primary state conveys the most important state information for a port/interface by combining the admin and operational states. The Multilayer Trace displays either a port primary state or alarm status. For the Chassis View, if an element in the Chassis View does not support changing color to indicate a state change, you can still get the state change information from the alarm that is generated for the state change.

Port/Interface Admin Status—The port/interface admin status represents the configured state of the port or interface (for example, if an administrator has manually shut down a port).
Port/Interface Admin Status |
Icon |
Description |
Unknown |
Port/interface admin status is unknown. There is no response (or insufficient response) from the device. |
|
Admin Down |
Port/interface was manually shut down by the administrator. |
|
Up |
Port/interface is enabled by administrator. |
|
Test |
Port/interface is being tested by the administrator. |
Port/Interface Operational State—A port/interface's operational state conveys the port or interface's running state and whether it is working properly.

Description |
Unknown |
Port/interface operational state is unknown. There is no response (or insufficient response) from the device. |
|
Down |
Port/interface is not working properly. |
|
Up |
Port/interface is receiving and transmitting data. |
|
Auto Up |
Port/interface is receiving and transmitting data (only certain devices support this state; other devices use "Up"). |
Circuit/VC Primary States— A circuit/VC's primary state conveys the most important state information for a circuit, in this order: Serviceability, Discovery, Alarm, Provisioning. It is normally shown in the first column in a table of circuits.

Circuit/VC Serviceability States— A circuit/VC's serviceability state is a combination of the circuit/VC's admin and operational states. The admin state is shown because it impacts service operability and (for optical circuits) determines whether the Activate and Deactivate actions are available. The operational state is shown to quickly identify whether a service is working or not.
Circuit/VC Discovery States—A circuit/VC's discovery state represents the latest state and structure of a service and its components, as discovered from the network. Having a Discovered version means that the application is actually monitoring the service itself, e.g. it can define meaningful operational and performance data.
Circuit/VC Discovery State |
Icon |
Description |
Partial |
Circuit/VC partially discovered by CEPNM; not all of its expected entities have been discovered. |
|
Full |
Circuit/VC fully discovered by CEPNM, so CEPNM can monitor the service and provide meaningful operational and performance data. |
|
Missing |
Circuit/VC not yet discovered by CEPNM (though it may have been provisioned). |
Circuit/VC Provisioning States—A circuit/VC's provisioning state represents whether there is a provisioning intent for a circuit/VC and, if so, its status. If a reconciliation report has been generated, the state of the reconcile action is reflected.
Link Serviceability States
Serviceability State |

Description |
Admin Down |
Link was purposefully shut down by administrator. |
|
Down |
Link is down (but it should not be). |
|
Up |
Link is up and traffic is passing through the link. |
|
Auto Up |
Link is up because it detected a signal (this state is only supported by optical devices) |
|
Unavailable |
Link is not discovered by yet or the status is unavailable. |
|
Partial |
|
Equipment Operational State—The equipment operational state represents the running state of the network element.
