Link Summary Panel

Link Summary

Summarizes the selections you made. To change the Link Summary, click Back and change your selection(s).

Note	• Once the links are created, each link will have a different color notation depending on the alarm
	status of the PTP on which the link is created. Links between Not Managed/Other Vendor NEs are
	always black. The color of the link between an MDS 9000 or a Not Managed/Other Vendor NE and
	a CTC-based NE is the color of the TP of the CTC-based NE. The colors are green for no alarm,
	yellow for minor alarms, orange for major alarms, and red for critical alarms. Invalid links (as
	reflected in the Is Link Valid attribute) are gray. An autodiscovered link can become invalid if 1) the
	DCC is disabled on either PTP, 2) either PTP is placed out of service, 3) there is a fiber cut or
	transmitter/receiver failure, or 4) either NE is marked Out of Service. Manual links are colored to
	match the highest alarm severity on either PTP. L2 links are always gray.
	• Links that are supported in different layer rates can be created only if the link endpoints are
	compatible with the specified layer rate.
	• If CTM discovers a link, it automatically assigns layer rates based on its endpoint.

Table 3-13summarizes link color as it relates to link type and the involved NEs.
