new sessions and max sessions

[sib2017]

Hi,

What are the differnces between the metric new sessions and max sessions .

I can see sessions per sessions from cli .How can i see new sessions count 

Thank you

Hello,

Max sessions would be the maximum supported sessions that the device can concurrently sustain, new sessions would be either new sessions since boot up or rate of new sessions established per second.

You can use this command to find out all that information:

> show session info 

You'll get an output like this:

show session info

--------------------------------------------------------------------------------
Number of sessions supported: 65534
Number of active sessions: 134
Number of active TCP sessions: 105
Number of active UDP sessions: 29
Number of active ICMP sessions: 0
Number of active BCAST sessions: 0
Number of active MCAST sessions: 0
Number of active predict sessions: 0
Session table utilization: 0%
Number of sessions created since bootup: 282139
Packet rate: 30/s
Throughput: 96 kbps
New connection establish rate: 0 cps
--------------------------------------------------------------------------------
Session timeout
TCP default timeout: 3600 secs
TCP session timeout before SYN-ACK received: 5 secs
TCP session timeout before 3-way handshaking: 10 secs
TCP half-closed session timeout: 120 secs
TCP session timeout in TIME_WAIT: 15 secs
TCP session timeout for unverified RST: 30 secs
UDP default timeout: 30 secs
ICMP default timeout: 6 secs
other IP default timeout: 30 secs
Captive Portal session timeout: 30 secs
Session timeout in discard state:
TCP: 90 secs, UDP: 60 secs, other IP protocols: 60 secs
--------------------------------------------------------------------------------
Session accelerated aging: True
Accelerated aging threshold: 80% of utilization
Scaling factor: 2 X
--------------------------------------------------------------------------------
Session setup
TCP - reject non-SYN first packet: False
Hardware session offloading: True
IPv6 firewalling: False
Strict TCP/IP checksum: True
ICMP Unreachable Packet Rate: 200 pps
--------------------------------------------------------------------------------
Application trickling scan parameters:
Timeout to determine application trickling: 10 secs
Resource utilization threshold to start scan: 80%
Scan scaling factor over regular aging: 8
--------------------------------------------------------------------------------
Session behavior when resource limit is reached: drop
--------------------------------------------------------------------------------
Pcap token bucket rate : 10485760
--------------------------------------------------------------------------------
Max pending queued mcast packets per session : 0
--------------------------------------------------------------------------------

Additionally you can see live stats by using this command:

> show system statistics session 

hope this helps,
