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 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.
Examples:
02_Port-2_1.log
02_Port-2_2.log
02_Port-2_3.log
02_Port-2_4.log
02_Port-2_5.log
PC Card Logging
Data can be logged to a PC Card Compact Flash that is loaded into one of the PC Card
slots on the front of the SLC and properly mounted (see
11:
PC Card
). Data logged
locally to the SLC is limited to 256 Kbytes and may be lost in the event of a power loss.
Data logged to a PC Card Compact Flash does not have these limitations. The system
administrator can define the file size and number of files per port. 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.
Examples:
02_Port-2_1.log
02_Port-2_2.log
02_Port-2_3.log
02_Port-2_4.log
02_Port-2_5.log
Email/SNMP Notification
The system administrator can configure the SLC to send an email alert message
indicating a particular condition detected in the device port log to the appropriate parties
or an SNMP trap to the designated NMS (see
7: Services
). The email or trap is triggered
when a user-defined number of characters in the log from your server or device is
exceeded, or a specific sequence of characters is received.
Use the Device Ports – Logging page to set logging parameters on individual ports.
To set logging parameters:
