Lucent ComOS 3.3.1 Release The new Lucent ComOSTM 3.3.1 software release is now available for the PortMaster® 2E, 2ER, 2, 2R, and 25 Communications Servers. Lucent shipped ComOS 3.3, an interim release, with the new 5-BRI ISDN expansion module in December of 1995. The new ComOS 3.3.1 includes all the functionality of ComOS 3.3, plus many other new useful features. All new shipments of the 5-BRI ISDN module will include ComOS 3.3.1. NOTE: Some of the features in ComOS 3.3.1 were added to support the 5-BRI ISDN module. The 5-BRI module is only supported by the PortMaster 2E & 2ER. There are however, many other new features in ComOS 3.3.1 for PortMaster 2, 2R, and 25 users as well. This release note describes the features of ComOS 3.3 and then the additional features of ComOS 3.3.1. It also includes information on where to get the 3.3.1 software image and how to upgrade your PortMaster. You need the new pminstall version 3.3 to upgrade to ComOS 3.3.1. Look in the How to upgrade section below for more details. This software release is provided free of charge to all Lucent PortMaster customers. New features in ComOS 3.3 and 3.3.1 Bug fixes in ComOS 3.3 and 3.3.1 Basic Rate Interface (BRI) support Configuring ISDN New RADIUS Attributes Memory Usage in ComOS 3.3 and 3.3.1 for PM-2E How do I upgrade? New features in ComOS 3.3 ISDN Basic Rate Interface (BRI) support Dynamic loadable software modules for memory management Multilink PPP on ISDN Multilink V.120 Per user port limit (for Multilink PPP and Multilink V.120) Per user idle timeouts Per session time limits IP numbered interfaces through User Table BOOTP support Called-Station-Id and Calling-Station-Id accounting additions Outbound PAP authentication Require PAP option Increase in active interfaces ARP entries cleared on Frame Relay RADIUS accounting sends notification of PortMaster boot ComOS 3.3.1 adds the following new features: 5ESS Custom Point-to-Point ISDN Support Data over voice for both inbound and outbound ISDN connections. New AT strings for more user control for outbound ISDN dialing. Input and output octet counters in RADIUS Accounting. Port Type included in RADIUS Authorization and Accounting. RFC 1877 support added so clients can learn their DNS server from PortMaster. Location Table entries made simpler and easier. !root login on serial ports can be disabled. Ascend Multilink PPP compatibility Console now ignores modem type and autolog Non-printing characters allowed in passwords RADIUS Accounting records signed Descriptions of New Features in ComOS 3.3 ISDN Basic Rate Interface (BRI) support ISDN basic rate interface support has been added. This release added full support for the new MOD-10I-U 5 BRI ISDN expansion boards available for the PortMaster 2E and 2ER. Consult the "Installing the MOD-10I-U ISDN Expansion Board" release note for a full list of supported capabilities. Dynamic loadable software modules Memory management has been improved and dynamic load modules have been implemented. Device drivers now only load if the specific device is present in the PortMaster (ie. sync port or ISDN). In addition if SNMP or IPX are not needed they can be disabled to save memory. The commands "set ipx off" and "set snmp off" will cause the modules to not load. Any device drivers or subsystems not needed can provide additional operational memory for the PortMaster. See the memory guidelines below for PortMaster memory requirements. IMPORTANT - to use IPX, you must now use the "set ipx on" command. If you are upgrading from a previous release and had IPX configured, it will default to on in this release. When turning IPX or SNMP off, you must do a "save all" and reboot the PortMaster before the change takes effect. Multilink PPP ComOS 3.3 supports Multilink PPP (MP) as described in RFC 1717 for ISDN interfaces. MP is supported concurrently with the Lucent Multi-line Load Balancing. The PortMaster will automatically detect and accept both Multi-line Load Balancing and Multilink PPP connections. Outbound, the PortMaster can be set to use Multilink PPP via the Location Table by entering "set location Location_Name Multilink on". Multilink V.120 Multilink V.120 is supported across ISDN ports. This allows the Lucent PowerLink128 ISDN PC modem to make 128Kbps connections to the PortMaster. Second connections generate PowerLink128 RADIUS accounting records. Per user port limit (for Multilink PPP and Multilink V.120) Maximum number of ports can be set on a per user basis within a single PortMaster. If left unconfigured, port limits will not be imposed. If a port limit is set, the user will be limited to that maximum number of ports on the PortMaster for Multilink V.120 and Multilink PPP sessions. This feature can be used to restrict which users can have service greater than 64 Kbps. Per user port limits can be set for user profiles residing in either the local user table, or via RADIUS. 1) For the user table (stored locally in the PortMaster), the following command is used: Command> set user username maxports number Examples- Command> set user jsmith maxports 2 Command> set user tjones maxports 1 2) For RADIUS, the Port-Limit attribute has been added to the user profile. (see New RADIUS attributes for more info) Per user idle timeouts Idle timeouts on a per user basis have been added. Idle timeouts can be set in the local User Table or can be provided as part of a new RADIUS Idle-Timout attribute. To set them in the User Table, use the following command: Command> set user Username idle Minutes (see New RADIUS attributes for more info)
