Administrators and Ethernet device users with rights to a device may add ports to that device. This is useful when a device does not automatically report port information.
To add a port: Notes:
The example below shows how to add an SLC port. Ports on other devices do not require extra port information such as baud and flow control).
During auto detect, if an SLC device does not have SNMP enabled, it will not retrieve these extra SLC port parameters. Then this SLC device is marked with an internal flag to indicate that those port parameters are incorrect. When this flag is set, the user cannot perform a "Write info to device" as this would push incorrect port settings back to the SLC device. This flag is cleared if the user did a "Read info from device" or manually modified one of the SLC device port settings. After this flag is cleared, the user can perform "Write info to device."
1. On the Ports tab of the Device page, click the Add Port button at the bottom. The following page opens:
Port Setting Description
Name Name of the Ethernet device port.
Port Number Number of the Ethernet device port (e.g., a number between 1 and 48 for the SLC 48 device).
Console Name of the parent Ethernet device.
Log Enabled Indicates whether logging has been enabled for this port.
Note: To enable or disable port logging for one or more ports, select the check box for each affected port, and select Enable Port Logging or Disable Port Logging from the drop-down list at the bottom of the page.
Only SLC devices that have established a secure channel connection can have ports with logging enabled.
Log Time Frame For SLC v3.1 and later v3.x (but not v4.0): The maximum time frame in hours before a new log file is created. The default setting is 1 hour.
For SLC v4.0 and later: The maximum time frame in seconds before the SLC console manager sends data to the vSLM 2 software. The default is 30 seconds.
Max Log Size (KB) Maximum size of each log file in kilobytes. Once it is reached, a new log file is created. The default setting is 256 KB.
Byte Threshold For SLC v4.0 and later: The number of bytes the SLC device port receives before it forwards them to the vSLM 2 software. For example, a threshold preset at 128 characters means that as soon as the SLC console manager receives 128 bytes of data on this particular device port, it captures log data and sends it to the vSLM 2 secure management software. The minimum byte threshold is 1, and the default is
1024.

Table 9-47 New Port - Configure Tab
Port Setting Description
Port Number Number of the Ethernet device's port (e.g., a number between 1 and 48 for the SLC 48 device). The system offers all unassigned ports up to 16 above the current highest port number.
Parent Ethernet Device (view only)
Name of the Ethernet device.
Name Name of the port (e.g., name of the device to which it is attached).
Parent Device Type (view only)

Log Enabled Indicates whether logging is enabled on the port. Disabled by default.
Note: To enable or disable port logging for one or more ports, select the check box for each affected port, and select Enable Port Logging or Disable Port Logging from the drop-down list at the bottom of the page.
Only SLC/SLB devices that have established a secure channel connection can have ports with logging enabled.
Log Time Frame For SLC v3.1 and later v3.x (but not v4.0): The maximum time frame in hours before a new log file is created. The default setting is 1 hour.
For SLC v4.0 and later: The maximum time frame in seconds before the SLC console manager sends data to the vSLM 2 software. The default setting is 30 seconds.
Max Log Size (KB) Maximum size of each log file in kilobytes. Once it is reached, a new log file is created. The default setting is 256 KB.
Byte Threshold For SLC v4.0 and later: This is the number of bytes the SLC device port receives before it forwards them to the vSLM 2 software. For example, a threshold preset at 128 characters means that as soon as the SLC console manager receives 128 bytes of data on this particular device port, it captures log data and sends the received data regarding this device port to the vSLM 2 secure management software. The minimum byte threshold is 1, and the default is 1024.
Receiving SLM(s) An SLC port can log its port data to one, two, or three SLM units at the same time. This field shows the IP address(es) of any SLM management appliance(s) that are receiving log data from this particular SLC port. These IP addresses need not necessarily include the SLM unit you are looking at.
Break Sequence A series of one to ten characters users can enter on the command line interface to send a break signal to the external device. A suggested value is Esc+B (escape key, then uppercase "B" performed quickly but not simultaneously). You would specify this value as \x1bB, which is hexadecimal (\x) character 27 (1B) followed by a B.
Managed Device Not active when you are adding a port.
Data Setting Description
Baud The speed with which the device port exchanges data with the attached serial device.
From the drop-down list, select the baud rate. Most devices use 9600 for the administration port, so the device port defaults to this value. Check the equipment settings and documentation for the proper baud rate.
Data Bits Number of data bits used to transmit a character. From the drop-down list, select the number of data bits. The default is 8 data bits.
Stop Bits The number of stop bit(s) used to indicate that a byte of data has been transmitted. From the drop-down list, select the number of stop bits. The default is 1.
Parity Parity checking is a rudimentary method of detecting simple, single-bit errors. From the drop-down list, select the parity. The default is none.
Flow Control A method of preventing buffer overflow and loss of data. The available methods include none, xon/xoff (software), and RTS/CTS (hardware). The default is none.
