Description

Summary

Provides an overview of the cross-connect card (XC10G, XCVT, XC) usage:

  • STS-1 Matrix: (XC10G, XCVT, XC) Provides the percentage of the cross-connect card STS-1 path resources that are used. 288 STS-1 paths are available for XC or XCVT cards; 1152 STS-1 paths are available for XC10G cards.

  • VT Matrix Ports: (XC10G, XCVT) Provides the percentage of the cross-connect card VT matrix ports that are used. Each port is one STS in size and each can transport 28 VT1.5s. 24 VT matrix ports are available for the XCVT and XC10G cards.

  • VT Matrix: (XC10G, XCVT) Provides the percentage of the VT matrix resources that are used. 672 are available, which is the number of VT matrix ports (24) multiplied by the number of VT1.5s in an STS (28).

VT Matrix Port Detail

Provides details of the VT Matrix Port usage:

  • Drop: Identifies the source slot, port, and STS.

  • Tunnel Name: If the port is used by a VT tunnel, the tunnel name appears here. VT tunnels use VT matrix ports on the tunnel source and destination nodes, but do not use matrix resources on pass-through nodes.

  • % Used: Shows the percentage of the matrix port that is used. Each matrix port can carry 28 VT1.5s, so for example, if one STS carries seven VT1.5 circuits, the matrix port appears as 25 percent used.

  • Usage: Shows the port usage. For example, if one STS carries seven VT1.5 circuits, the matrix port will show that 7 of 28 are used.

Refresh

Updates the XC resources display.

Delete

Deletes STSs that use VT matrix resources but no longer carry VT circuits. This occasionally occurs when many VT circuits are added and deleted over a period of time. Stranded STSs appear as STSs with 0% usage in the VT Matrix Port Detail area. If stranded STSs appear, click the STS, then click Delete to free up VT matrix capacity.
