•
Files deleted to free up disk space
Event logs at the Informational level are generated for normal situations:
•
Disk partition completion
•
RAID discovery results without overwriting
•
RAID construction completion
•
RAID disk added or removed
•
File system initialization
•
NFS service start
•
Files copied/removed from CDR module to RAID disk
The hard disk supports SNMP notifications which are described in the
SNMP MIB Reference
.
When the hard-disk is filled, dynamically created records files in the folder
/hd-raid/record
will be deleted
to free up space. Other user-created files on the disk should be cleaned up manually.
Important
Packet Processing Cards: PSC2 and PSC3
The packet processing cards provide packet processing and forwarding capabilities within a system. Each
card type supports multiple contexts, which allows an operator to overlap or assign duplicate IP address ranges
in different contexts.
You cannot mix packet processing card types in the same chassis.
Caution
Specialized hardware engines support parallel distributed processing for compression, classification, traffic
scheduling, forwarding, packet filtering, and statistics.
The packet processing cards use control processors to perform packet-processing operations, and a dedicated
high-speed network processing unit (NPU). The NPU does the following:
•
Provides "Fast-path" processing of frames using hardware classifiers to determine each packet's processing
requirements
•
Receives and transmits user data frames to and from various physical interfaces
•
Performs IP forwarding decisions (both unicast and multicast)
•
Provides per interface packet filtering, flow insertion, deletion, and modification
•
Manages traffic and traffic engineering
•
Modifies, adds, or strips datalink/network layer headers
•
Recalculates checksums
•
Maintains statistics
•
Manages both external line card ports and the internal connections to the data and control fabrics
