Automatic Nameserver Configuration

The primary and secondary name server’s addresses can either be statically configured as above, or learned dynamically over an interface. Name servers can be learned via DHCP over an Ethernet interface or via IPCP over a PPP interface. The interface is specified using the command:

ADD IP DNS [DOMAIN={ANYdomain-name}] INTERFACE=interface

If no nameservers have been manually configured, and nameserver configuration is assigned to an interface by either PPP or DHCP, this configuration will be automatically used for the default nameservers. Name servers configured in this way are identified by an “*” in the “Domain” column of the SHOW IP DNS output table. Automatically-configured nameservers can be deleted or replaced, using the commands:

DELETE IP DNS

SET IP DNS

A deleted automatic configuration may subsequently reappear if the interface concerned is reset.

Telnet Server Port Number

The listen port for the Telnet server is now configurable, so that it can be changed from the default value 23.

The LISTENPORT parameter has been added to the SET TELNET command.

The syntax is:

SET TELNET [TERMTYPE=termstring] [INSERTNULL={ONOFF}] [LISTENPORT=port]

The LISTENPORT parameter sets the TCP port over which the Telnet server listens for connections. If this parameter is not used, the default port number is 23.

If the TCP listen port is changed from the default of 23, care must be taken to ensure that any firewall or IP filtering configurations are matched accordingly.

Triggers for Ethernet Interfaces

Support for Ethernet UP and DOWN triggers on Ethernet interfaces has been added, as per existing triggers for other interface types. This limitation on the CREATE TRIGGER and SET TRIGGER commands is removed.

CREATE TRIGGER=trigger-idINTERFACE=interface EVENT={UPDOWN FAILANY} [CIRCUIT=miox-circuit] [CP={APPLEATCPBCPCCP DCPDNCPIPCPIPXCPLCP}] [DLCI=dlci]] [AFTER=hh:mm] [BEFORE=hh:mm] [{DATE=dateDAYS=day-list}] [NAME=name] [REPEAT={YESNOONCEFOREVERcount}] [SCRIPT=filename...] [STATE={ENABLEDDISABLED}] [TEST={YESNOONOFFTRUE FALSE}]
