Field Descriptions for the Link Table (continued)

 

 

 

Field

 

Description

 

 

 

Is Link Valid

 

Validity of the link. Values are Valid or Invalid. For autodiscovered links, the value is Valid if both

 

 

the terminating NEs are in service and the NEs are able to confirm the presence of the link. An

 

 

autodiscovered/manual link is invalid if (1) the DCC is disabled on either PTP; (2) either PTP is

 

 

placed Out of Service (OOS); (3) there is a fiber cut or transmitter/receiver failure; or (4) either NE

 

 

is marked OOS. For manual links, the value is Valid or Invalid.

 

 

The following rules apply to link validity:

 

 

• All invalid links are shown as gray in the Network Map.

 

 

• Valid links are shown in the Network Map with a color corresponding to alarm severity, with

 

 

green for no alarm, yellow for minor alarms, orange for major alarms, and red for critical

 

 

alarms.

 

 

• Manual and unmanaged links can be valid or invalid.

 

 

• A link between an unmanaged NE and a managed NE can be valid or invalid. If the link is valid,

 

 

it is shown with the same color as the PTP alarm on the managed NE.

 

 

• The delete link operation is available for all links except for valid, autodiscovered links. You

 

 

can delete links of the following type:

 

 

– Manual (valid and invalid)

 

 

– Virtual (valid and invalid)

 

 

– Unmanaged (valid and invalid)

 

 

– Invalid autodiscovered

 

 

Link Connection Type

Whether the link connection is inter-NE or intra-NE.

 

 

An inter-NE link represents an external fiber connection between PTPs on different NEs. An

 

 

intra-NE link represents a fiber connection between two PTPs on the same NE.

 

 

Link Protection Type

Whether the link protection is unprotected, 1+1, 1+1 with Y-cable protection, 2-Fiber

 

 

BLSR/MS-SPRing, 4-Fiber BLSR/MS-SPRing, or Not Applicable.

 

 

For ONS 155xx NEs, protection types are Y-Cable/Line Card Protection, Trunk Protection, Splitter

 

 

Protection, or No Protection. The Y-Cable protection type also applies to ONS 15454 SONET and

 

 

ONS 15454 SDH NEs.

 

 

Used for Routing

Whether the selected link is used for routing. Value is Yes or No.

 

 

 

Link Name

 

Name of the selected link.

 

 

Link Description

User-entered description of the selected link. If the user does not modify the <System Default>

 

 

string shown in the Create Link wizard, the description is a string built from the end point

 

 

information.

 

 

 

Alarm Counts

 

Total number of critical, major, minor, and warning alarms associated with the selected link.

 

 

Note This field does not apply to ONS 155xx NEs.

 

 

 

Link Cost

 

Numeric cost associated with the selected link. The link cost is used while routing a circuit. The

 

 

lowest link cost is preferred in circuit routing. The Cisco default value is 1024. This attribute is

 

 

editable for manual links in the SONET or SDH layer.
