SP maintenance statistics are described in the following table:
 
SP Maintenance Statistics (/stats/slb/sp/maint) 
Statistic
Description
Maximum sessions
The maximum number of simultaneous sessions supported.
Current Sessions
The number of session bindings currently in use (the last four and 64 seconds).
Terminated Sessions
The number of sessions removed from the session table because the server assigned to them failed, and graceful server failure was not enabled.
Allocation Failures
Indicates instances where Alteon ran out of available sessions for a port.
TCP Fragments
Indicates the number of TCP fragments encountered by Alteon. Layer 4 processing may not handle TCP fragments, depending on the configuration.
UDP Datagrams
Indicates that the virtual server IP address and MAC are receiving UDP frames when UDP balancing is not turned on.
Non TCP/IP Frames
Indicates the number of non-IP based frames received by the virtual server.
Incorrect VIPs
Indicates the number of times Alteon received a Layer 4 request for a virtual server which was not configured.
Incorrect Vports
A dropped frames counter that indicates that the virtual server has received frames for TCP/UDP services that have not been configured. Normally this indicates a mis-configuration on the virtual server or the client, but it also may be an indication of a potential security probing application like SATAN.
No Available Real Server
A dropped frames counter that indicates that all real servers are either out of service or at their maxcon limit.
Backup Server Activations
This indicates the number of times a real server failure has occurred and caused a backup server to be brought online.
Overflow Server Activations
This indicates the number of times a real server has reached the maxcon limit and caused an overflow server to be brought online.
Filtered (Denied) Frames
This indicates the number of frames that were dropped because of one of the following reasons:
*They matched an active filter with the deny action set.
*There are no real servers, in the case of redirection filters.
*There are no available session entries.
LAND attacks
This counter increases whenever a packet has the same source and destination IP addresses and ports.
No TCP Control Bits
The number of packets that were dropped because the packet had no control bits set in the TCP header.
Invalid reset packet drops
The number of packets that were dropped because the packet had an invalid reset flag set.
Total IP fragment sessions
This represents the total number of fragment sessions Alteon has processed so far.
Current IP fragment sessions
This represents the current number of fragment sessions.
IP fragment discards
The number of fragmented packets that are discarded due to lack of resources.
IP fragment table full
This counter indicates how many times session table is full.
