When the map command is invoked with the timeout argument, a similar 16 x 16 grid is
displayed that contains the number of message timeouts from the remote since last
cleared. In the timeout grid, the value of “.” Represents the value zero, and “*”
represents a value greater than 99. Numeric values were not used for zero to enhance
readability as this grid tends to be sparse.
When the
map command is invoked with the argument of clear, both the address map
and the timeout grid are manually cleared. All of the E2A addresses are then acquired
dynamically and the map is rebuilt.
6.2.13 Configuring User Prompt
Syntax: uprompt [ “User Prompt” | STD ]
The uprompt command command supports custom user prompting for ports of
type=orig. In the default condition, a user is prompted with a xxxx Destination> prompt
string where xxxx is the actual device number. If the uprompt command is issued with a
double quoted string, that string is presented as the user prompt without the double
quotes. The maximum size of the prompt string is 31 characters. The value of STD
returns the xxxx user prompt to its default, or standard, configuration.
6.3 IP-GATE PORT COMMANDS
These commands are used to configure the operation of the single IP-GATE port on the
4180. There are two basic objects to be configured. The first, the screening/routing table,
determines which packets will be directed to the outgoing path. The second is the
specification of the path across the IP infrastructure to either a stand-alone IP-GATE, the
IP-GATE port on another 4180, a 4000, or a 6xxx Network Processor running IP-
FANOUT. Although the command structure has been designed to accommodate
multiple paths, only a single path ( i.e. idx=0 ) is supported at the present time.
6.3.1 IPGATE ROUTE
Syntax: ipgate route < idx = k > [ addr = < ipaddr > ]
[ mask = < submask > ]
[ path = < path_idx > ]
[ act = < rte | drop | del> ]
The ipgate route command builds the screening and routing table for the IP-GATE port.
This table may have up to 8 entries, indexed 0-7 by the idx parameter. Each entry is for
a range of IP addresses (specified by the addr and mask parameters), and an action to
perform (specified by the act parameter) if the packet’s destination address falls into this
range. These entries have precedence, i.e., entry 0 is evaluated before entry 1, etc., as
each outgoing packet is inspected, and the indicated action is immediately performed
when a match is found. If a match occurs on an entry for which act=RTE, the packet is
routed. If act=DROP, the packet is explicitly dropped. If no entry in the table matches the
packet’s destination IP address, the packet is dropped and an exception is logged.
Setting the act parameter to DEL deletes the entry.
