These release notes summarize the functions of the Cisco MGX 8240 Private Line Service Gateway switch software, Release 2.2.0.6. 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 (2.2.0.4). 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.
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 MGX 8240 systems previously shipped to Williams Networks are to be upgraded to the new swithc software being shipped.
The software upgrade procedure supports the following Switch Software Releases:
 |
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.
Finally, the Cisco MGX 8240 CPE can be upgraded from Release 1.1.2.10 directly to Release 2.2.0.6 or from Release 2.1.0.6 to Release 2.2.0.4 or from Release 2.2.0.4 to Release 2.2.0.6 using the Upgrade Procedure provided below.
The following bugs that existed in Release 2.2.0.4 have been fixed and verified in Release 2.2.0.6
| DDTS Number | SeveritySeveSrity | Functional Area | Problem Description | Corrected |
CSCdp56732 | High | BERT | Creating loopbacks on circuits that are under BERT testing causes future connections on that port to fail creation. Also, half-created or half deleted circuits cannot be fully deleted due to erroneous check. | Creating local loopbacks on circuits under BERT is now blocked. |
CSCdp93716 | High | Redundancy | Race condition in performing forceback can cause lost configuration. | Race condition is resolved with extra synchronization. |
Cisco MGX 8240 CPE/CS3 Switch software (Release 2.2.0.6) has some known problems. Every attempt has been made to resolve the problems of high severity. Below are the known problems that remain, including all outstanding problems related to the CES modules and associated I/O ports.
| DDTS Number | SeveritySeveSrity | Functional Area | Problem Description | Corrected | |
Sn04840 | High | Switch Shaping | Policing on Ascend 550 causes inband cells to be dropped because Maximum Burst Size(MBS) is not configurable and fixed to 1024 cells. | Do not turn on policing at Ascend, or set it to 1024 cells. | Same as 1.1.1.2 |
Sn04752 | Low | Switch Craft Interface | Double ESC required to exit from DS1 statistics window on Craft Interface. |
| Same as 1.1.1.2 |
Sn05174 | High | Xyplex | FTP fails sometimes due to Xyplex's problem. | Pending on Xyplex new fix. | Same as 1.1.1.11 |
Sn05554 | High | 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.
| Workaround: 1. On NMS go to the port's Near End Loopback. Invoke a Near End Loopback, then drop the loop. 2. Go to the Far End Loopback and invoke the loop first and then drop it. | Bug found in 1.1.2.10 |
Dm61874 | Low | Port State | When using OC3 IO, STS Path LOP and Label Mismatch will not automatically show a problem in the contained DS3 state. | Workaround: Look at OC3 state as well as DS3 state when using OC3 IO. |
|
Dm90409 | Low | Inband | When an operation to change inband parameters fails due to invalid parameters, future reads of parameters will return the invalid parameters. | Workaround: when changing inband parameters fail, resave the old parameters. | Will be fixed in next release. |
Dm93724 | Low | IO card state | With the introduction of a new IO card type, if a blade is booted without an IO card connected in the back slot, the switch will declare an alarm. Other attributes cannot give accurate information without an IO card present. | The switch expects that an IO card is present when the blade is booted. |
|
Dm66546 | Low | Inband | Setting inband address to default through VCLI does not work. | Workaround: Set to default using CMDR. |
|
Dm76776 | Low | Alarms | Alarms are not cleared when in test mode.
| As per Functional Specification, alarms are neither set nor cleared when in test mode. However, status fields are reported. |
|
Dm78670 | Low | CES stats | Cell rate reported differently.
| In release 2 the cell rate has been dropped from 4110 to 4109 in order to accommodate 2016 circuits. |
|
Dm92060 | Medium | Inband | Inband does not always come up active. | Occasionally inband does not come up active when the OC3 is up. Workaround is to toggle the OC3 state from up to test and back to up. Data is not affected. |
