Overview

This procedure is used to clear a Receive buffer overflow condition. The condition indicates that insufficient SONET bandwidth (not full rate) is provisioned for the specified Data port.

Before you begin

Prior to performing this procedure:

Refer to Before you begin and Required equipment in this chapter.
Refer to Electrostatic discharge in Chapter 1, Safety.

Steps

Complete the following steps to clear a Receive buffer overflow condition.


1	From the WaveStar^® CIT System View, click the Alarm List button and locate the `Receive buffer overflow` condition in the resulting alarm list.
2	Refer to the Probable Cause column in the alarm list, and note the corresponding AID.
3	Select Configuration → Cross-Connections to access the Cross-Connection Wizard and provision the required additional STSn add/drop cross-connections. The ESCON mode supports only full-rate service requiring a minimum of 4 STS-1s (6 STS-1s may be required for other vendor equipment), or 2 STS3c, or 1 STS12c cross-connections. The Data ports will not carry traffic end-to-end unless the full rate is provisioned. The FC-1G mode supports partial-rate and full-rate service requiring a minimum of 19 STS-1s or 6 STS3c (7 STS-3c may be required for other vendor equipment) cross-connections. The Data ports will carry traffic when end-to-end paths are established in both directions. The FC-2G mode supports partial-rate and full-rate service requiring a minimum of 37 STS-1s (38 STS-1s may be required for other vendor equipment) or 12 STS3c (13 STS-3c may be required for other vendor equipment) cross-connections. The Data ports will carry traffic when end-to-end paths are established in both directions. The FICON-1G mode supports full-rate service requiring a minimum of 19 STS-1s or 6 STS3c (7 STS-3c may be required for other vendor equipment) cross-connections. The Data ports will not carry traffic end-to-end unless the full rate is provisioned. The FICON-2G mode supports full-rate service requiring a minimum of 37 STS-1s (38 STS-1s may be required for other vendor equipment) or 12 STS3c (13 STS-3c may be required for other vendor equipment) cross-connections. The Data ports will not carry traffic end-to-end unless the full rate is provisioned.
4	From the System View, select View → Cross-Connections to obtain the current list of cross-connections and verify that the proper cross-connections have been made. End of steps
