Ethernet Interface   4

  This chapter describes how to use the command line interface to configure the Ethernet interfaces of the PortMaster 4. The PortMaster 4 manager module comes with two routable Ethernet interfaces, a 10BaseT Ether0 and 10/100BaseT Ether1.
  ComOS releases 4.1 and later also support a standalone Ethernet board with one 10/100BaseT interface (Ether0) and a standalone dual Ethernet module with two 10/100BaseT interfaces (Ether30 and Ether31). A PortMaster 4 can have only one dual Ethernet module, and it must be installed in slot 3. No new commands are required to support the standalone Ethernet board and module.
  For additional information about installing and configuring the Ethernet ports of the PortMaster 4, refer to the PortMaster 4 Installation Guide  and PortMaster 4 Configuration Guide .
  Detailed command definitions follow a command summary table.
  Commands for configuring subinterfaces on Ether0 are also summarized and defined in this chapter.

  Note ¯ To activate any changes to the configuration of Ether0--the 10BaseT interface on the manager module--you must use reboot . For all other Ethernet interfaces, you must use the appropriate reset slot  command.

       Ethernet Commands

  These commands affect the Ethernet interfaces of the PortMaster 4--Ether0, Ether1, and the standalone Ethernet module and boards. All Ether0 commands can be used for Ether1 and the standalone Ethernet module and boards, except as noted in this section. You can configure the Ethernet interfaces from any view.
  Lucent recommends that network traffic--syslog , traceroute , telnet , DNS, ChoiceNet, RADIUS, and TFTP--be configured using Ether1. 
 

       set Ether0 address

  This command sets the IP address of the Ethernet interface.

  set Ether0 address Ipaddress [/NM]|[Ipmask]

 
 Ether0  One of the following Ethernet interfaces:
   ether0   10BaseT interface on the manager module.
   ether1   10/100BaseT interface on the manager module.
    ether00  Single 10/100BaseT Ethernet interface on the standalone Ethernet board in slot 0.
   ether10  Single 10/100BaseT Ethernet interface on a standalone Ethernet board in slot 1.
   ether20  Single 10/100BaseT Ethernet interface on a standalone Ethernet board in slot 2.
   ether30  Single 10/100BaseT Ethernet interface on a standalone Ethernet board or the first Ethernet interface on a dual Ethernet module in slot 3.
   ether31  Second 10/100BaseT Ethernet interface on a dual standalone Ethernet module in slot 3.
   ether50  Single 10/100BaseT Ethernet interface on a standalone Ethernet board in slot 5.
   ether60  Single 10/100BaseT Ethernet interface on a standalone Ethernet board in slot 6.
   ether70  Single 10/100BaseT Ethernet interface on a standalone Ethernet board in slot 7.
   ether80  Single 10/100BaseT Ethernet interface on a standalone Ethernet board in slot 8.
   ether90  Single 10/100BaseT Ethernet interface on a standalone Ethernet board in slot 9.

  Note ¯ You must configure Ether0 or Ether1 with an IP address for the standalone Ethernet board or dual Ethernet module to function.

 Ipaddress  IP address or hostname.
 /NM  Optional netmask--an integer between 1 and 32 that indicates the number of high-order bits set to 1. Enter a slash (/) between the IP address and the netmask in bits.
 Ipmask  Optional netmask expressed in dotted decimal notation. Enter a space between the IP address and the netmask.

  Each 10/100BaseT Ethernet interface on the PortMaster 4 has an alternative media-independent interface (MII) for connection to fiber and copper media. ComOS uses the MII if both it and the RJ-45 interface are connected.

  Note ¯ To activate any changes to the configuration of Ether0--the 10BaseT interface on the manager module--you must reboot ; for all other Ethernet interfaces you must use the appropriate reset slot  command.

  If you change the IP address of an Ethernet interface, you must disable and then re-enable IP on the Ethernet interface for the change to take effect.
 

       set Ether0 broadcast

  This command determines which broadcast address the PortMaster will use.

  set Ether0 broadcast high|low

 
 Ether0  For a list of configurable Ethernet interfaces, see page 4-3.

  Note ¯ You must configure Ether0 or Ether1 with an IP address for the standalone Ethernet board or dual Ethernet module to function.

 high  Use a host part of all ones (for example, 192.168.1.255) in the broadcast address.
 low  Use a host part of all zeros (for example, 192.168.1.0) in the broadcast address. This is the default.

  This setting must match the broadcast address used by all hosts and routers on the same network segment. For the PortMaster 4, Lucent recommends that you connect Ether0  and Ether1  to separate Ethernet segments.
 

       set Ether0 ifilter

  This command sets a packet filter for evaluating packets entering the PortMaster on the Ethernet interface.

  set Ether0 ifilter [Filtername

 
 Ether0  For a list of configurable Ethernet interfaces, see page 4-3.

  Note ¯ You must configure Ether0 or Ether1 with an IP address for the standalone Ethernet board or dual Ethernet module to function.

 Filtername  Input filter name that is in the filter table. Filtername  can be up to 15 characters.
]

  The filter must be created before it can be used. Refer to the PortMaster 4 Configuration Guide for more information on how to construct a filter. If the filter is changed, this command must be re-entered for the changes to take effect on the Ethernet interface.
  You need not reboot the interface nor the PortMaster to activate the filter. To remove the filter, enter the command without a filter name.

  Note ¯ You can set the filtername to the Ethernet interface before the filter is created, but doing so allows packets to pass through without any packet filtering.

 

       set ether0 ip

  This command enables or disables the IP protocol on the interface.

  set ether0 ip enabled|disabled

 
 enabled  Enables IP. This is the default.
 disabled  Disables IP.

  This command is available only on the Ether0 interface.
 

       set ether0 ipx

  This command enables or disables the IPX protocol on the interface.

  set ether0 ipx enabled|disabled

 
 enabled  Enables IPX.
 disabled  Disables IPX.

  This command is available only on the Ether0 interface.

  Note ¯ The PortMaster 4 supports IPX protocols on ComOS 4.1 and later releases.

 
 
 

       set Ether0 ipxframe

  This command sets the IPX frame type.

  Note ¯ Enter this command on one line, without any breaks. The line break shown here is due to the limited space available.

  set Ether0 ipxframe ethernet_802.2|ethernet_802.2_ii
| ethernet_802.3|ethernet_ii

 
 Ether0  Ethernet interface.
 ethernet_802.2  Use Ethernet 802.2 protocol. This is the default encapsulation used by Novell NetWare 4.0.
 ethernet_802.2_ii  Use Ethernet 802.2_ii protocol. This encapsulation is not commonly used.
 ethernet_802.3  Use Ethernet 802.3 protocol. This is the default encapsulation used by Novell NetWare 3.11.
 ethernet_ii  Use Ethernet II protocol. This encapsulation is sometimes used for networks that handle both TCP/IP and IPX traffic.

  The encapsulation method and frame type were selected when your Novell IPX network servers were installed. The PortMaster IPX settings must match those of your IPX network.

  Note ¯ The PortMaster 4 supports IPX protocols on ComOS 4.1 and later releases.

 
 

       set Ether0 ipxnet

  This command sets the IPX network number for the Ethernet interface.

  set Ether0 ipxnet Ipxnetwork

 
 Ether0  Ethernet interface.
 Ipxnetwork  A 32-bit hexadecimal value.

  The IPX network number must be entered in hexadecimal format, as shown in the example. You must enable IPX before using this command.

  Note ¯ The PortMaster 4 supports IPX protocols on ComOS 4.1 and later releases.

 
 

       set Ether0 mproxy

  This command enables the PortMaster 4 to monitor Internet Group Management Protocol (IGMP) multicast traffic from a heartbeat group of multicast routers.

  set Ether0  mproxy address Ipaddress |port Tport |src-address Ipaddress |
src-netmask Netmask| slot Seconds| number Number| timeout Seconds|
 alarm Number

 
 Ether0  ether0  or ether1 .
 address Ipaddress  Broadcast address that identifies a multicast group--in dotted decimal notation.
 port Tport  TCP port--an integer between 1 and 65535--on which the PortMaster 4 listens for a heartbeat.
 src-address Ipaddress  IP address of the heartbeat source in dotted decimal notation, or the hostname--a string of up to 39 characters.
 src-netmask Netmask  Netmask for the heartbeat source in dotted decimal notation.
 slot Seconds  Length of a time slot in seconds--an integer between 0 and 120.
 number Number  Number of time slots--an integer between 1 and  6.
 timeout Seconds  Period of multicast host inactivity after which the PortMaster 4 disconnects the host. timeout  is an integer between 60 and 600.
 alarm Number  Minimum number of slots that must receive a heartbeat--an integer between 1 and 6. Otherwise, the PortMaster 4 sends an SNMP alarm.
 

  The PortMaster 4 supports the multicast heartbeat feature on ComOS 4.1 and later releases.
  This command sets time slots during which a multicast-enabled hosts must receive multicast traffic for the heartbeat group. Use this command to detect problems with multicast traffic by keeping track of multicast messages from the heartbeat group. If the number of slots receiving a heartbeat is lower than the set alarm  value, the PortMaster 4 sends an SNMP alarm.
  To activate new configuration settings, you must first use the reboot  command.

  Note ¯ The PortMaster 4 does not currently support this command on the standalone Ethernet boards.

  Command> set ether1 mproxy address 244.0.0.99 port 2000 src-address 192.168.20.1 src-netmask 255.255.255.255 slot 120 number 5 timeout 360 alarm 3
  set Ether0 mproxy on|off - page 4-10
show igmp - page 4-14
 

       set Ether0 mproxy on

  This command enables the Ethernet interface to listen for Internet Group Management Protocol (IGMP) broadcasts and send multicast broadcasts.

  set Ether0  mproxy on|off

 
 Ether0  ether0  or ether1 .
 on  Enables the PortMaster 4 to listen for IGMP broadcasts from multicast-enabled hosts in its multicast group on the specified Ethernet interface.  Setting multicast proxy routing on  also enables the PortMaster 4 to broadcast the IGMP member report for all other multicast-enabled hosts in its multicast group to other multicast routers
 off  Disables multicast proxy routing on the specified interface.

  The PortMaster 4 supports IGMP multicast proxy on ComOS 4.1 and later releases.
  To enable dial-in clients for multicast, you must configure corresponding RADIUS attributes. For more information about enabling users for multicast proxy, see the latest ComOS release notes.
  To display multicast proxy heartbeat settings, use the show  Ether0  command.

  Note ¯ The PortMaster 4 does not currently support this command on the standalone Ethernet boards.

  show Ether0 - page 4-12
show igmp - page 4-14
set igmp - page 4-9

  Note ¯ You must configure Ether0 or Ether1 with an IP address for the standalone Ethernet board or dual Ethernet module to function.

 Filtername  Output filter name, up to 15 characters, that is in the filter table.

  The filter must be created before it can be used. Refer to the PortMaster 4 Configuration Guide for more information on how to construct a filter. If the filter is changed, you must be re-enter this command for the changes to take effect on the Ethernet interface.
  You need not reset nor reboot the interface or the PortMaster to activate the filter. To remove the filter, enter the command without a filter name.
 

  Note ¯ You can set the filtername to the Ethernet interface before the filter is created, but doing so allows packets to pass through without any filtering.

       Ethernet Subinterface Commands

  The PortMaster 4 supports the configuration of Ether0 on the manager module for multiple IP subnets. The MAC address for the subinterfaces is the same as that for the primary interface.
  Because Ethernet subinterfaces are rebuilt every time a new subinterface is added, they can be viewed but not modified with the ifconfig  command.

  Note ¯ RIP, OSPF, packet filtering, and route propagation are not supported on Ethernet subinterfaces.

  The commands in Table 4-2 configure and manage Ether0 for subinterfaces.
