CAS Profile
An administrator can configure settings for ports that are assigned to the CAS Profile. The CAS
Profile option has four options shown in the following table.
To configure the protocol, authentication, auto discovery and other general
settings for ports configured with CAS Profile:
1. Select Appliance Settings - Ports - CAS Profile - Default Settings - General . The General
screen appears.
NOTE: Default settings to the CAS Profile are intended for new CAS ports. CAS ports with previously-configured
default settings will not be affected unless they are edited in Appliance Settings - Ports - Physical Ports or by
using the Multi-Edit Wizard in Appliance Settings - Ports - CAS Profile - Devices .
2. Select the desired protocol(s) (SSH, Telnet or Telnet/SSH) that can be used to access the serial
port/target device from the Protocol pull-down menu.
3. Select the desired authentication type from the drop-down menu.
NOTE: Port authentication authenticates the user for one session.
Table 4.1: CAS Profile Options
Option Description
Default Settings Configure the connection protocol, authentication, auto discovery and other general
settings
Devices Configure one or more ports that have the CAS Profile
Auto Answer Configure an auto answer input and output string
Auto Discovery Configure settings and probe and match strings for ports that are configured for auto
discovery. When auto discovery is enabled, if the hostname of the connected target
device is successfully discovered, the hostname is shown instead of the serial port
alias. This feature can save time for administrators because they do not need to enter
port aliases manually. If the console server is being managed through DSView 3
software, hostname discovery can be configured through the DSView 3 software.
Probe and match strings are used to probe the target device that is connected to the
serial port and to extract a hostname from the answer that is received in response to the
probe string. The result of each probe string is compared against all match strings.
Each time no match is found, the next probe string is sent until there are no more probe
strings.
Default probe and answer strings used for auto discovery have a broad range and work
in most cases. An administrator can configure site-specific probe strings and answer
strings. Probe string configuration requires knowledge of C-style escape sequences.
Match strings require knowledge of POSIX extended regular expressions. Hostnames
longer than 31 characters are truncated when the hostname is assigned to the serial
port alias.
