Introduction

Introduction

These release notes summarize the functions of the Cisco MGX 8240 Private Line Service Gateway switch software, Release 2.2.0.3. These notes describe new features and enhancements as well as a list of known caveats that have been fixed and verified since the previous deployed Release (1.1.2.10). The document also lists open caveats.

These notes are intended for customer functional and operational groups and Cisco System Engineers responsible for installing and provisioning the Cisco MGX 8240 Private Line Service Gateway.

New and Changed Information

The Cisco MGX 8240 Private Line Service Gateway systems previously shipped are to be upgraded to the new switch software.

The purpose of this release is to resolve problems found in the switch functions. Therefore, there are no new features as part of this release.

The following fixes and enhancements have been incorporated into Release 2.2.0.3:

•

•

•

•

•

Support for APS protected Channelized Access OC3 interface

Major rework and improvement of redundancy

Support of 2016 DS0 circuits

SNMP trap IP address changes and enhancements

•

•

•

•

CES connection loopback towards TDM or ATM

Connection BERT towards TDM or ATM

OAM loopback delay test

DS1 Out-Of-Frame Stats

•

•

Connection based control of Loss of Cells reporting

T1 SF and ESF loopback support

Improved bootup diagnostics

Upgraded Products

The software upgrade procedure supports the following Switch Software Releases:

• 1.1.2.10 (general release of 3/5/99)

•

•

2.1.0.6 (general release of 8/11/99)

2.2.0.1 (genera release of 9/9/99)

Note All Releases prior to Release 1.1.2.10 must first be upgraded to Release1.1.2.10 using the upgrade procedure for Release 1.1.2.10, before this Release can be applied.

Before the Cisco MGX 8240 CPE software can be upgraded, the VCLI must first be upgraded to Version

2.1.0 or higher. Separate documents provide release notes for the VCLI and information on upgrade procedures for the VCLI.

Xyplex

BERT

FTP failed sometimes due to Xyplex’s problem.

Circuit will not pass data if it is created while

DS1s on both ends of a local circuit are under BERT.

FE Loopback If the user manipulates the far-end

DS1 loop modes more rapidly than the 1.5 second

(the loop send code duration time), the far-end

Larscom

CSU/DSU and the Cisco

MGX 8240

DS1 port are both in a loop up mode. Once this happens, the loop down command issued from

Sentient NMS is unable to take Larscom

CSU/DSU out of a loop.

Pending on Xyplex new fix.

Workaround: Delete and create the circuit again after the BERT is stopped.

Workaround:

1.

2.

On NMS go to the port's Near End

Loopback. Invoke a

Near End

Loopback, then drop the loop.

Go to the Far End

Loopback and invoke the loop first and then drop it.
