Port logging is disabled by default. You can enable more than one type of logging (local, NFS file, email/SNMP, USB port, or PC Card) 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 Device Ports - Logging web 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 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: __.log. Examples: 02_Port-2_1.log 02_Port-2_2.log SLC™ Console Manager User Guide 96
