Ethernet OAM |

Ethernet OAM is enhanced for the following:
|
|
Ethernet OAM |
7.3(0)D1(1) |
This feature was introduced. |
Ethernet as a Metro Area Network (MAN) or a Wide Area Network (WAN) technology benefits greatly from the implementation of Operations, Administration and Maintenance (OAM) features. Ethernet link OAM features allow Service Providers to monitor the quality of the connections on a MAN or WAN. Service providers can monitor specific events, take actions on events, and if necessary, put specific interfaces into loopback mode for troubleshooting. Ethernet link OAM operates on a single, physical link and it can be configured to monitor either side or both sides of that link.
A Link OAM profile can be configured, and this profile can be used to set the parameters for multiple interfaces.
Link OAM can be configured directly on an interface.
When an interface is also using a link OAM profile, specific parameters that are set in the profile can be overridden by configuring a different value directly on the interface.
An EOAM profile simplifies the process of configuring EOAM features on multiple interfaces. An Ethernet OAM profile, and all of its features, can be referenced by other interfaces, allowing other interfaces to inherit the features of that Ethernet OAM profile.
Individual Ethernet link OAM features can be configured on individual interfaces without being part of a profile. In these cases, the individually configured features always override the features in the profile.
The preferred method of configuring custom EOAM settings is to create an EOAM profile in Ethernet configuration mode and then attach it to an individual interface or to multiple interfaces.
Neighbor Discovery
Link Monitoring
Miswiring Detection (Cisco-Proprietary)
Neighbor discovery enables each end of a link to learn the OAM capabilities of the other end and establish an OAM peer relationship. Each end also can require that the peer have certain capabilities before it will establish a session. You can configure certain actions to be taken if there is a capabilities conflict or if a discovery process times out, using the capabilities-conflict or discovery-timeout commands in the action configuration submode.
Link monitoring enables an OAM peer to monitor faults that cause the quality of a link to deteriorate over time. When link monitoring is enabled, an OAM peer can be configured to take action when the configured thresholds are exceeded.
Miswiring Detection is a Cisco-proprietary feature that uses the 32-bit vendor field in every Information OAMPDU to identify potential miswiring cases.
You must be in a user group associated with a task group that includes proper task IDs. The command reference guides include the task IDs required for each command. If you suspect that user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Cisco NX-OS Release 8.2(3) has the following Ethernet OAM enhancements:
Frame error threshold values can be configured on the Ethernet link to measure the quality of the link.
Error-disabled ports need to be manually shut/no shut to bring the port up.
The error-disabled ports need to be manually shut/no-shut to bring the ports to the up state. This is applicable to all the Ethernet OAM links except for link-oam-dying-gasp and for link-oam-discovery-timeout if the errdisable recovery cause is configured with the link-oam-dying-gasp and link-oam-discovery-timeout options.
This recovery mechanism for link-oam-dying-gasp and link-oam-discovery-timeout links is introduced in Cisco NX-OS Release 8.2(3).
The following modules are supported from Cisco Nexus Release 7.3(0)D1(1):
M2-Series 10-Gigabit Ethernet Series Module for Cisco Nexus 7000 Series Switches.
F3-Series 10-Gigabit Ethernet Series Module for Cisco Nexus 7000 Series Switches and Cisco Nexus 7700 Switches.
Ethernet OAM is not supported on the F2 series modules.

Creates a new Ethernet Operations, Administration and Maintenance (OAM) profile and enters Ethernet OAM configuration mode. |
||
|
Step 4 |

Enters the Ethernet OAM link monitor configuration mode. |
||
|
Step 6 |
(Optional) symbol-period window window Example: |
(Optional)
Configures the window size (in milliseconds) for an Ethernet OAM symbol-period error event. The range is 1000 to 60000. The default value is 1000. |
||
|
Step 7 |
(Optional) symbol-period threshold low threshold [high threshold] Example: |
(Optional)
Configures the thresholds (in symbols) that trigger an Ethernet OAM symbol-period error event. The high threshold is optional and is configurable only in conjunction with the low threshold. The range is 1 to 60000000. The default low threshold is 1. |
||
|
Step 8 |
(Optional) frame window window Example: |
(Optional)
Configures the frame window size (in milliseconds) of an OAM frame error event. The range is 1000 to 60000. The default value is 1000. |
||
|
Step 9 |
(Optional) frame threshold low threshold high threshold Example: |
(Optional)
Configures the thresholds (in frames) that triggers an Ethernet OAM frame error event. The high threshold is optional and is configurable only in conjunction with the low threshold. The range is 1 to 12000000. The default low threshold is 1. |
||
|
Step 10 |
(Optional) frame-period window window Example: |
(Optional)
Configures the window size (in milliseconds) for an Ethernet OAM frame-period error event. The range is 1000 to 60000. The default value is 1000. |
||
|
Step 11 |
(Optional) frame-period threshold low threshold [high threshold] Example: |
(Optional)
Configures the thresholds (in frames) that trigger an Ethernet OAM frame-period error event. The high threshold is optional and is configurable only in conjunction with the low threshold. The range is 1 to 1000000. The default low threshold is 60000. The IEEE 802.3 standard defines threshold crossing events as number of error frames in a window. To comply with the standards, the low and high threshold for frame-period events is measured in errors per million frames. Hence, the calculation to determine the remote low and high threshold is (configured threshold * frame window in received Bridge Protocol Data Unit (BPDU))/1000000. For example, if the received frame window=300, then high threshold is 20000 * 300 / 1000000 = 6. |

Configures the window size (in milliseconds) for the OAM frame-seconds error event. The range is 10000 to 900000. The default value is 60000. |

Using an EOAM profile is an efficient way of configuring multiple interfaces with a common EOAM configuration. However, if you want to use a profile but also change the behavior of certain functions for a particular interface, then you can override the profile configuration. To override certain profile settings that are applied to an interface, you can configure that command in interface Ethernet OAM configuration mode to change the behavior for that interface.
In some cases, only certain keyword options are available in interface Ethernet OAM configuration due to the default settings for the command. For example, without any configuration of the action configuration submode commands, several forms of the command have a default behavior of creating a syslog entry when a profile is created and applied to an interface. Therefore, the log keyword is not available in Ethernet OAM configuration for these commands in the profile because it is the default behavior. However, the log keyword is available in Interface Ethernet OAM configuration if the default is changed in the profile configuration so you can retain the action of creating a syslog entry for a particular interface.
To configure Ethernet OAM settings at an interface and override the profile configuration, perform the following steps:
| Command or Action | Purpose | |
|---|---|---|
|
Step 1 |
configure terminal Example: |
Enters global configuration mode. |
|
Step 2 |
interface type slot/port Example: |
Specifies an interface to configure, and enters interface configuration mode. |
|
Step 3 |
ethernet oam Example: |
Enables Ethernet OAM and enters interface Ethernet OAM configuration mode. |
|
Step 4 |
hello-interval interval-time Example: |
Configures Ethernet OAM hello interval limit for an interface. The possible values for hello interval is 100 millisecond or 1 second. The default value is 1 second. |
|
Step 5 |
interface-Ethernet-OAM-command Example: |
Configures a setting for an Ethernet OAM configuration command and overrides the setting for the profile configuration, where interface-Ethernet-OAM-command is one of the supported commands on the platform in Interface Ethernet OAM configuration mode. |
|
Step 6 |
end Example: |
Ends the configuration session and exits to the EXEC mode. |
