ComOS 3.5 Release NotePM-3 VERSION ONLYIntroductionThe new Lucent Technologies ComOSTM 3.5 software release is now available for the PortMaster® 3 Integrated Access Server. This release note documents commands and features in ComOS release 3.5 in addition to those described in the OSPF chapter of the Command Line Administrator's Guide (available in late December, 1996) and the "Configuring the PortMaster 3" chapter of the PortMaster 3 Installation Guide (included with the PortMaster 3). Both manuals are available in PostScript and Adobe Acrobat PDF format on the Lucent Technologies FTP site, ftp://ftp.livingston.com:/pub/le/doc/manuals/. New Features in ComOS 3.5ComOS 3.5 includes the following new features: Support for the PortMaster 3 Integrated Access Server and True Digital Modems. Variable Length Subnet Masks. In previous releases ComOS required the same netmask to be used for all subnets of a network. In release 3.5 variable length subnet masks (VLSM) are supported. To ease the transition, the command "set user-netmask off" is available; see below for details. OSPF - see the OSPF Chapter in the Command Line Administrator's Guide, which is available now in PostScript and Adobe Acrobat PDF format on our FTP site ftp://ftp.livingston.com/pub/le/doc/manuals/ and will be available in printed form in late December, 1996. MultiChassis PPP - The "set endpoint" command now enables MultiChassis PPP. The size of Assigned Address Pool can be set with the "set pool" command. Digital Modem SpecificationsData Modulations:
Support for ITU V.34 Annex 12 - 33,600 bps will be added in a future release. High Level Data Protocols:
Modem SupportFollowing is a list of modems tested for compatibility with the True Digital¿ Modems in the PortMaster 3. For a more complete list see http://www.livingston.com/Marketing/Products/pm3qa.html and http://www.livingston.com/Tech/Appnotes/index.html.
T1/E1 Loopbackset Line0 loopback on|off When line0 or line1 is set to T1 or E1 operation, you can set it for local network loopback, for testing purposes. Variable Length Subnet MasksComOS release 3.5 now supports Variable Length Subnet Masks. In previous releases ComOS required the same netmask to be used for all subnets of a network. In release 3.5 variable length subnet masks (VLSM) are supported. To ease the transition, the command "set user-netmask off" will treat all netmasks specified in the User Table or RADIUS as though they were 255.255.255.255, the way earlier releases did. The command "set user-netmask on" will add a route based on the specified netmask. The default is off. In ComOS release 3.3.3 and earlier the PortMaster always used 255.255.255.255 for the user's Framed-IP-Netmask, regardless of the value of the Attribute. ComOS 3.5 adds support for Variable Length Subnet Masks (VLSM) but by default ignores the Framed-IP-Netmask the same way earlier releases did. To have 3.5 accept the netmask value, issue the following commands on the PortMaster: set user-netmask on save all After user-netmask is set on, the PortMaster will use the actual value of the Framed-IP-Netmask to update the routing table when a user logs in. USE CAUTION with this feature, since it affects both routing and Proxy ARP on the PortMaster. If you only want to route to that one host, use the attribute
Framed-IP-Netmask = 255.255.255.255
You should always use Netmask 255.255.255.255 when using the PortMaster assigned address pool (or omit the attribute, which defaults to 255.255.255.255). If you want to route to an entire 24-bit subnet, you would use
Framed-IP-Netmask = 255.255.255.0
Note that in some cases this may mean that the Framed-Route attribute may no longer be necessary. Assigned Pool SizeThe PortMaster allocates a pool of IP addresses starting at the Assigned Address (set from the global menu or by the "set assigned") and counting up. The total number of addresses is equal to the number of ports configured for Network Dialin. If someone dials in and requests an unused address from the pool, that is assigned; if someone dials in and requests any address, the next address from the pool is assigned, if someone disconnects, their address is placed at the end of the pool for re-use. In Release 3.5 the size of the pool can also be set explicitly with the "set pool Number" command, where Number will be the number of IP addresses allocated to the pool. If the pool size is decreased the PortMaster should be rebooted for the change to take effect. OSPFSee the OSPF Chapter in the Command Line Administrator's Guide, which is available now in PostScript and Adobe Acrobat PDF format on our FTP site ftp://ftp.livingston.com/pub/le/doc/manuals/ and will be available in printed form in late December, 1996. Some additional commands were added after that manual went to press and are documented here. Before configuring ospf, you must first do the following: set ospf enable save all reboot reset ospfThe "reset ospf" command resets the OSPF router engine in the PortMaster, and should be used after making changes to the PortMaster's OSPF configuration. OSPF cost, hello-timer, dead-timerOSPF cost, hello-timer and dead-timer are now configurable by interface. Note: The value for cost, hello-interval and dead-time must be the same for all routers attached to a common network. set Ether0 ospf on cost Number This command determines the cost of sending a packet on the interface, expressed in the link state metric. Number is a number from 1 to 65535. The default value is 1. Example: set ether0 ospf on cost 2 set Ether0 ospf on hello-interval Number This command determines how often the hello packet is transmitted, from 10 to 120 seconds. The default value of hello-interval is 10 seconds. Example: set ether0 ospf on hello-interval 40 set Ether0 ospf on dead-time Number This is the number of seconds after ceasing to hear a neighbor router's hello packets, that the remote router is marked as down. Range is 40 to 1200 seconds. The default value is 40 seconds. Example: set ether0 ospf on dead-time 60 Modem CommandsThe following commands were added after the Command Line Administrator's Guide went to press. set location Locname analog on|off show modems show M0 set debug mdp-events|mdp-status|mdp-internal|mdp-max on|off set location Locname analog on|off on = use an analog modem to dial out to this location off = use isdn to dial out to this location Dialout locations can use either analog modem or ISDN. It uses PAP or CHAP to authenticate itself to the location dialed. The remote end must auto-detect PPP; you cannot use dialout chat scripts in ComOS release 3.5 on the PortMaster 3. Show modem displays the modem status; ACTIVE if the modem is in use, READY if the modem is available for use, ADMIN if the modem has been busied out. pm3> show modem MdmPortStatusSpeed CompressionProtocolCallsRetrain Disconnect ------------------ ------------------------------- ---------- M0 S2 ACTIVE 28800 V42BIS LAPM 2 0 NORMAL M1 S3 ACTIVE 28800 V42BIS LAPM 1 0 NORMAL M2 S4 ACTIVE 28800 V42BIS LAPM 1 0 NORMAL M3 READY UNKNWN NONE NONE 0 0 NORMAL

MultiChassis PPPMultiChassis PPP (MCPPP) supports Multilink PPP (RFC 1717) across multiple PortMasters sharing an ethernet, to allow the use of MP across multiple PortMasters in a single telephone hunt group. To enable MCPPP use the "set endpoint" command. MCPPP FeaturesLoad balancing - In a hunt group configuration, traffic will be automatically switched to subsequent units if it is saturated on the first unit. Master and Slave Links - If the Master link goes down for any reasons, the Master unit will continue process the Slave links as long as they still exist. Master and Slave units - If the Slave unit is out of service, the Master links will continue to function. However, if the Master unit if out of service, the Slave links will cease to exist since the Master unit is required to process its links. MCPPP CommandsEnabling MCPPPUse the following commands on all PortMasters sharing a hunt group and Ethernet, using the same 12 digit hexadecimal endpoint discriminator on all of them. For convenience you may wish to use one PortMaster's ethernet MAC level address as the endpoint discriminator for all the PortMasters on that hunt group, but any 12-digit hexadecimal number will work. set endpoint 00C005123456 save all reboot The Endpoint Discriminator takes effect after the PortMaster is rebooted. show mcppp This command displays the mcppp table with the neighboring units in the same domain, the port number, user name, destination, the port type, and the IP addresses of the peer units. show global This command displays the End Point Discriminator address. show session The "show session" command on the Master unit now shows the virtual ports that are corresponding to the physical ports of the Slave unit. The virtual ports indicate by the letter V followed by the port number. reset V0 V0 is a virtual port number, v0, v1, etc. This command is used on the Master unit to reset the virtual port. Since the virtual port has a corresponding physical port on the Slave unit, once the virtual port is reset on the Master, its corresponding physical port will not be available on the Slave. Debugging MCPPPTo enable MCPPP debugging, use the "set console" command followed by any of the following commands: set debug mcppp-event Displays all the events related to the MCPPP links. set debug mcppp-history Displays the most recent 40 events. To disable debugging, use the "set debug off" command, and "reset console" to release the console. Quick Setup ExampleThis example configures a PortMaster 3 to use two PRI lines for dial-in by modem or ISDN users, with RADIUS authentication and accounting. Refer to the "Configuring the PortMaster 3" chapter in the PortMaster 3 Installation Guide for more information. Change the values and addresses shown to match your actual requirements. In this example, the RADIUS and RADIUS accounting servers are at 192.168.1.3, the default routing gateway is 192.168.1.1, and the PM-3 will assign dynamic IP addresses to dial-in users from the range 192.168.1.4 through 192.168.1.49 (if using two 23 channel PRI's) or 192.168.1.63 (if using two 30 channel PRI's). set password Hard2Guess set ether0 address 192.168.1.2 set gateway 192.168.1.1 set isdn-switch att-5ess save all reboot set assigned 192.168.1.4 set loghost 192.168.1.3 set authenticate 192.168.1.3 set accounting 192.168.1.3 set secret UpTo15Character save all Copyright and Trademarks© Copyright 1997 Lucent Technologies, Inc.
