<SSH flags> is one or more of:
user <Login Name>
version <1|2>
command <Command to Execute>
tcp <IP Address> port <TCP Port>
telnet <IP Address> [port <TCP Port>]
udp <IP Address> port <UDP Port>
hostlist <Host List>
Notes: To escape from the connect direct command when the endpoint of the
command is deviceport, tcp, or udp and return to the command line interface, type the
escape sequence assigned to the currently logged in user. If the endpoint is telnet or
SSH, logging out returns the user to the command line prompt.
To escape from the connect listen command, press any key. Setting up a user with
an escape sequence is optional. For any NIS, LDAP, RADIUS, Kerberos, or TACACS+
user, or any local user who does not have an escape sequence defined, the default
escape sequence is Esc+A.
When connecting to a USB device port, buffered data collected while there was no active
connection to the device port may be displayed initially. This is due to clearing internal
buffers in preparation for the new connection to the device port.
Device Ports - Logging and Events
The SLC products support port buffering of the data on the system's device ports as well as
notification of receiving data on a device port. Port logging is disabled by default. You can enable
more than one type of logging (local, NFS file, token and data detection, SD card, or USB port) at
a time. The buffer containing device port data is cleared when any type of logging is enabled.
Local Logging
If local logging is enabled, each device port stores 256 Kbytes (approximately 400 screens) of I/O
data in a true FIFO buffer. You may view this data (in ASCII format) at the CLI with the show
locallog command or on the Devices > Device Ports - Logging & Events page. Buffered data is
normally stored in RAM and is lost in the event of a power failure if it is not logged using an NFS
mount solution. If the buffer data overflows the buffer capacity, only the oldest data is lost, and only
in the amount of overrun (not in large blocks of memory).
NFS File Logging
Data can be logged to a file on a remote NFS server. Data logged locally to the SLC 8000
advanced console manager is limited to 256 Kbytes and may be lost in the event of a power loss.
Data logged to a file on an NFS server does not have these limitations. The system administrator
can define the directory for saving logged data on a port-by-port basis and configure file size and
number of files per port.
The directory path must be the local directory for one of the NFS mounts. For each logging file,
once the file size reaches the maximum, a new file opens for logging. Once the number of files
reaches the maximum, the oldest file is overwritten. The file naming convention is: <Device Port
Number>_<Device Port Name>_<File number>.log.
