Command |
Description |
|
Sets an IP interface option. | |
|
Defines an IP interface. | |
|
Defines a gateway route. | |

Assigns the IP address of the TX board's redundant mate board. Required in a redundant configuration for both SIGTRAN and TDM networks. | |
|
Controls Ethernet data tracing. |
The ifopt command sets an IP interface option using the following syntax:
ifopt [!]<optName>[ = <optValue>]
where:
|
Value |
Description |
|
optName |
optName indicates that the option is enabled. !optName indicates that the option is disabled. |
|
optValue |
Value options are specified as: optName = optValue |
The following table lists the valid option names:
|
Option name |
Type |
Description |
|
PINGBLOCK |
BIT |
Indicates if automatic responses to PING messages are blocked. |
|
MTU |
VALUE |
Maximum transmission unit (in bytes). |
|
FRAGDROP |
SECS |
Partial fragment drop timeout. |
|
HOPLIMIT |
VALUE |
Reserved for future use. |
|
ICMPRATE |
VALUE |
Reserved for future use. |
|
IPV6 |
BIT |
Reserved for future use. |
|
IPSEC |
BIT |
Reserved for future use. |
|
NDATTEMPTS |
VALUE |
Specifies the neighbor discovery attempt (NDA) limit for the specified Ethernet interface. |
|
NDRETRAN |
SECS |
Neighbor discovery retransmission timeout. |
|
NDREACH |
SECS |
Reserved for future use. |
|
ARPRETRY |
MSECS |
Amount of time to wait after issuing an ARP request before re-transmitting the same ARP request. |
|
ARPMAX |
VALUE |
Maximum number of times to retry an ARP request before terminating retry attempts and considering the remote entity to be unreachable. |
|
ARPREACH |
MSECS |
Maximum amount of time without receiving any message from the remote IP address before probing to verify connectivity. |
|
ARPUNUSED |
MSECS |
Amount of time that an unused ARP entry remains in the ARP table. An ARP entry is used each time an outbound IP packet is sent to the remote entity for the given ARP entry. |
Enter the following command to block responses to received PING requests:
ifopt pingblock
Enter the following command to drop all fragments if incomplete after 10 seconds:
ifopt fragdrop 10
The ifcreate command defines an IP interface that uses either:
DHCP to determine IP address and mask, or
A fixed IP address and mask
An interface is created with default options unless options were specifically set using previous ifopt commands.
The ifcreate command syntax using DHCP is:
ifcreate intfNum DHCP
where:
|
Value |
Description |
|
intfNum |
1-based Ethernet interface number. |
|
DHCP |
Obtains the IP address, network mask, and default gateway. |
The following example shows an interface that uses DHCP:
ifcreate 1 dhcp
The ifcreate command syntax when not using DHCP is:
ifcreate intfNum IPaddr mask
where:
|
Value |
Description |
|
intfNum |
1-based Ethernet interface number. |
|
IPaddr |
IP address to assign to the interface. |
|
mask |
IP subnet mask. |
The following example shows an interface with a specific address and mask:
ifcreate 2 10.3.9.15 255.255.255.0
The gateway command defines a gateway route using the following syntax:
gateway IPaddress mask gatewayAddress
where:
|
Value |
Description |
|
IPaddress |
IPv4 address in dot notation. For example, 1.2.3.4. |
|
mask |
Mask associated with IP address, in dot notation. |
|
gatewayAddress |
IPv4 address, in dot notation, of routing gateway. |
The following example sends all traffic not covered by a more specific route to the gateway at 10.1.0.1:
gateway 0.0.0.0 0.0.0.0 10.1.0.1
The mate command assigns the IP address of the TX board's redundant mate using the following syntax:
mate IP address | NONE
where:
|
Value |
Description |
|
IP address |
IPv4 address in dot notation, for example 1.2.3.4. |
|
NONE |
No mate IP address (default). |
The following example indicates that the TX board's redundant mate is at address 10.1.1.2:
mate 10.1.1.2
Refer to the Dialogic® TX Series SS7 Boards Health Management Developer's Reference Manual for information about SS7 redundancy.
The ethtrace command controls Ethernet data tracing using the following syntax:
ethtrace <iface|*> on [<hostchan>]|off
To activate tracing of all Ethernet traffic as part of the TX board boot process, add the following command to the TX configuration file:
ethtrace * ON
This causes the TX board to trace all packets (sent or received over any on-board Ethernet interface) to the default trace channel (47). The ss7trace utility uses Channel 47 to receive all types of SS7 tracing. Refer to the Dialogic® TX Series SS7 Boards TX Utilities Manual for information about ss7trace.
The following example shows how Ethernet tracing can be activated for specific interfaces:
ethtrace 1 on
ethtrace 2 on
Ethernet tracing can also be directed to channels other than the default channel. The following example causes Ethernet 1 to trace to host channel 101 while Ethernet 2 traces to host channel 102:
ethtrace 1 on 101
ethtrace 2 on 102
To deactivate tracing, run the txconfig utility without a configuration file (interactive mode) and enter the following command:
txconfig> ethtrace * off
