Help for Packet Trace Link Add-Update
This help page explains how to add or update a link device. A link device cannot be updated or added when the trace is in an active or delay mode.
Service Point/Stack
The service point/stack to be traced.
Proc
The member name of the catalogued procedure used to start the TCPIP address space.
Domain
The NetView domain where the service point resides.
Link Name
If you are updating the link device you cannot change the link name field. If you are adding a link device enter the required valid defined link name in the space provided. Device links are defined in the TCP/IP address space through the LINK statement.
Packet Length
Specifies that a truncated portion of the IP packet is to be traced. You can specify a length by selecting the radio button Abbrev and entering a number in the range 1-65535 in the space provided. Select FULL to capture the entire packet. The default value is FULL.
Protocol
Specifies the protocol type to be traced. This can be one of the literals TCP=6, UDP=17, ICMP=1, and RAW=255, or as a Number in the range 0-255 in the space provided. Select ALL so any of the protocols will be traced. Select the corresponding radio button to pick which protocol type to be traced. The default value is ALL(*).
IP Address
Specifies an IP address that will be compared with both the source and destination addresses of inbound and outbound packets. If either the source or destination address of a packet matches the specified IP address, the packet will be traced. To specify a specific IP address, select the Specify radio button and enter the IP address in dotted decimal notation in the space provided. To specify all IP addresses, select the ALL(*) radio button. The default value is ALL(*).
SubNet
Specifies a subnet mask that applies to the host and network portions of the IP address specified on the accompanying IP parameter. To specify a specific subnet mask, select the Specify radio button and enter the mask in dotted decimal notation in the space provided. The subnet mask must be specified in conjunction with the IP parameter. To select the default subnet, select the 255.255.255.255 radio button.
Source Ports
Specifies a port number that will be compared with the source port of inbound and outbound packets. The port number is an integer in the range 1-65535. If the source port of a packet is the same as the specified port number, the packet will be traced. This comparison is only performed for packets using either the TCP or UDP protocol; packets using other protocols are not traced. To specify a specific port number, select the Specify radio button and enter the port number in the space provided. To specify all port numbers, select the ALL(*) radio button. If ALL(*) is specified, packets of any protocol and any source port will be traced. The default value is ALL(*).
Dest Ports
Specifies a port number that will be compared with the destination port of inbound and outbound packets. The port number is an integer in the range 1-65535. If the destination port of a packet is the same as the specified port number, the packet will be traced. This comparison is only performed for packets using either the TCP or UDP protocol; packets using other protocols are not traced. To specify a specific port number, select the Specify radio button and enter the port number in the space provided. To specify all port numbers, select the ALL(*) radio button. If ALL(*) is specified, packets of any protocol and any source port will be traced. The default value is ALL(*).
Update/Add Link
When you click the Update (Add) Link button your updated (added) link device will be saved and you will return to the Service Point Packet Trace Summary.
Note: Select the Back button to return to the previous panel without updating (adding) a link device.
