10: Device Ports Detect Port Name Detect Name Tokens Group Access Banner # of Sessions Msg Idle Timeout Msg Connected Msg New User Msg Minimize Latency If enabled, the EMG will attempt to detect the hostname of the device connected to the device port, and set the device port name to the detected hostname. Many devices use their hostname or another identifier as the device prompt, and the EMG can extract this name from the prompt using the Detect Name Tokens. If the device port name is set to the default value, when a user interacts with a device connected to a device port, the EMG will look for the device prompt and set the device port name. The device prompt must be output at least 3 times in a single session for the prompt to be detected and the name extracted from the prompt. Any characters that are not part of the allowed characters for the device port Name will be removed. If the device name is automatically detected, the name will be logged in the Device Ports log. If Detect Port Name is enabled, the EMG will attempt to extract a hostname or other identifier from the device prompt, to use as the device port name. The EMG will extract any name between either the start of a line sent from the device up until one of the tokens, or any part of a prompt that does not include the tokens, as the device port name. For example, if the device prompt is set to [EMG431d]>, and the Detect Name Tokens include "[" and "]", the EMG will extract the identifier EMG431d and set it as the device port name. If the device prompt is set to myrouter>, and the Detect Name Tokens include ">", the EMG will extract the identifier myrouter and set it as the device port name. If undefined, any group can access the device port. If one or more groups are specified (groups are delimited by the characters ' ' (space), ',' (comma), or ';' (semicolon)), then any user who logs into the device port must be a member of one of the specified groups, otherwise access will be denied. Users authenticated via RADIUS may have a group (or groups) provided by the RADIUS server via the Filter-Id attribute that overrides the group defined for a user on the EMG unit. A group provided by a remote server must be either a single group or multiple groups delimited by the characters ' ' (space), ',' (comma), ';' (semicolon), or '=' (equals) for example "group=group1,group2;" or "group1,group2,group3". Text to display when a user connects to a device port by means of Telnet, SSH, or TCP. If authentication is enabled for the device port, the banner displays once the user successfully logs in. Blank is the default. If enabled, a message will be displayed to a user when connecting to a device port that indicates how many users are currently connected to the device port. Disabled by default. If enabled, a message will be displayed to a user when their connection to a device port will be terminated soon due to the connection being idle. Disabled by default. Note: When the Idle Timeout Msg is enabled, the terminal application timeout values for Telnet, SSH and TCP should be set to a value greater than 15 seconds. If enabled, a message will be displayed to a user when they initially connect to a device port. Enabled by default. If enabled, a message will be displayed to all the users connected to the device port when a new user connects to the same device port. Disabled by default. Minimize device port latency by reducing read delays. This may improve communication efficiency in scenarios where a series of short messages are exchanged, but may increase central processing unit (CPU) utilization and decrease throughput in cases where large messages are transmitted. Disabled by default. EMG™ Edge Management Gateway User Guide 194
