About This Release Obtaining Documentation, Obtaining Support, and Security Guidelines, page 25 About This Release Version .201 of Release 5.4.00 is a patch release for VXSM that introduces a new feature (see DTMF Squelching, page 4). See Table 2 on page 16 for information about software that is compatible for use in a switch running version .201 of Release 5.4.00. These release notes describe the system requirements, new features, and limitations that apply to Release 5.
New Features • SNMPv3, page 6 • Trap Squelch Feature, page 6 • MPSM Licensing Changes, page 6 DTMF Squelching This release contains the enhancements to completely squelch DTMF digits. This feature can be provisioned using the CLI commands shown below. Note These CLI commands are not new for this release. They already exist in the product. For H.
New Features dspccdprofs Display clear channel data profiles Unique Virtual Gateway Domain Name for H.248 For H.248 applications, a VXSM card has the capability of being partitioned into a number of virtual media gateways (VMGs); where each VMG is a logical entity residing within a physical VXSM card. This feature permits each virtual gateway to be assigned its own unique domain name. The Unique Virtual Gateway Domain Name feature modifies the following commands: addh248assoc Add H.
Release 5.3.10 Features Flash MIB Support Network management systems (NMS) can manage software images stored in boot flash using SNMP when the device supports the CISCO-FLASH-MIB. The RPM-XF supports the CISCO-FLASH-MIB in Cisco IOS Release 12.4(14)T and later releases. For MGX 8800/8900 multiservice switches, the NMS can query objects defined in the CISCO-FLASH-MIB through the PXM management interface or the RPM-XF management interface.
Release 5.3.10 Features Enhanced VXSM Card Support Release 5.3.10 supports the Processor Switch Module Hard Disk Voice (PXM-HDV) back card, which supports four or more VXSM cards on an MGX 8880 media gateway. The size of the D partition on the PXM-HDV back card is 2000 Mb. Non-redundant Upgrade Procedure To migrate from PXM-HD to PXM-HDV back cards in a non-redundant configuration, perform the following steps: Step 1 Upgrade the PXM boot and runtime images to release 5.3.
Release 5.3.10 Features When the Relative Humidity is high, the air temp and dew point temperatures are very close. The opposite it true when the Relative Humidity is low. When the dew point temperature and air temperature are equal, the air is saturated with moisture. Locations with high relative humidities have air that is close to being saturated with moisture. When saturated air cools it cannot hold as much moisture and can cause moisture migration and penetration into the system.
Release 5.3.00 Features and Enhancements • Altitude – Minimum: Sea level – Maximum: 10,000 feet (3,050 meters) Release 5.3.
Release 5.3.00 Features and Enhancements SFTP Limitations The SFTP feature has the following limitations: • Maximum of 4 simultaneous sessions • Sessions have an infinite timeout • Must use forward slash (/) for path names • The following SFTP commands are not supported: – chown – chmod – chgrp – ln – rename, with absolute filenames – Symlink Disabling Telnet and FTP By default, the PXM45 permits unsecured access from Telnet and FTP clients, as well as secure access from SSH and SFTP clients.
Release 5.3.00 Features and Enhancements Step 6 Proceed with the normal software upgrade procedure. Alternatively, enter the resetsys command to reset the chassis. Note The resetsys command interrupts all traffic on the MGX chassis. Remote IP Management Connection Enhancements You can manage an MGX 8850 node directly from an Ethernet or console port on the PXM, or you can configure a remote path to the PXM through a service module or route processor module.
Release 5.3.00 Features and Enhancements Configuring an RPM Management Connection The following quick start procedure summarizes the RPM configuration procedure. This procedure assumes the RPM already has a switch partition configured for the management connection. Command Action Step 1 switch partition Create and configure a partition for switch 1, as necessary. Step 2 interface sw1. point-to-point Configure a point-to-point subinterface on switch 1.

Release 5.2.10 Features Release 5.2.10 Features Maintenance Release 5.2.10 does not introduce new Cisco MGX 8880 features or enhancements. Release 5.2.00 Features Release 5.2.00 introduced the following hardware: • MGX-VXSM-T3 front card • VXSM-BC-3T3 back card MGX-VXSM-T3 Card Cisco MGX 8880 Release 5.2.00 introduced a third VXSM card for the support of T3 lines. The card consists of a front card with six T3 ports and a half-height back card with three T3 ports.

Limitations, Restrictions, and Notes for 5.4.00 • The VXSM cards, when installed for the first time or after clearing the slot configuration, create a default configuration. The creation of a default configuration involves writing large amount of data to the hard disk in the node. When multiple VXSM cards are installed simultaneously or the configuration of multiple VXSM slots are cleared simultaneously, one or more VXSM cards could fail to be installed.
Limitations, Restrictions, and Notes for 5.4.00 • Currently, command names are verified, but an invalid command name might be parsed and added to the binary file. However, this invalid name is ignored later. • If replication to standby failed, the installation process failed. • The cnfcli accesslevel default command restores all command access levels to default for the service module that this command is executed on. This command does not remove the binary file, and this change is not persistent.
Limitations, Restrictions, and Notes for 5.4.00 • For the clear service module configuration feature, using the clrsmcnf command might result in discrepancy in the PNNI configuration. For example, some connections might be in the mismatch state. • If the clrsmcnf command is given with the option to clear the software version for the slot as well, then the card enters the boot/empty state after the operation is complete.
Limitations, Restrictions, and Notes for 5.4.00 • Changing the routing priority for DAX connections does not change the priority of the associated SVCs. The SPVCs are not derouted and rerouted if just the endpoint parameters are changed, and routing priority is an endpoint parameter. Also, because DAX connections are never derouted even if the user-network interface (UNI) port stops responding and the rrtcon command is not supported for DAX connections, the routing priority change is never reflected.
Known MGX 8880 Media Gateway Anomalies Manual Clocking When resetcd is invoked, the primary and secondary (if configured) clock sources are recommitted. However, the clock to which the node is latched is not requalified. Only the backup clock is qualified if present. Recommitted means that the primary and secondary are requalified, and the node temporarily latches onto the internal oscillator. After the clock is requalified, the node locks onto the primary clock source once again.
Known Route Processor Module Anomalies For information about anomalies with the VXSM card, refer to Release Notes for the Cisco Voice Switch Service Module (VXSM), Release 5.4.00. For information about anomalies with the VISM card, refer to Release Notes for the Cisco Voice Interworking Service Module (VISM), Release 3.3.30.
