b tmm output and b tcp stats show output how best to decypher?
Hi, I have a few questions here in regards to comprehending the output of the 'b show' commands.
1/ b tmm
I'm trying to determine some %'s from the 'b tmm' output. Such as 'no listen' denials. I would like to be able to work out the % or at least explain what a number such as 1287 (below) refers to in terms of frequency.
Eg
denials (maint, addr full, serv full) = (0, 0, 0)
| (no serv, no listen, no mem, no lic) = (0, 1287, 0, 0)
2/ b tmm
Can anyone explain what the letters stand for in b output commands, such as 'M' and 'G', and 'T'.
Mega packets, Mega bits??
eg
server (pkts,bits) in = (20.13M, 15.99G), out = (19.25M, 40.19G)
3/ b tcp stats show all - rxooseg sol6523 tells me this is of connections that received an out of order TCP segment. How does one give this number more meaning? (Ie versus in order segments.)
GLOBAL TCP STATISTICS
| Conn (open, CLOSE-WAIT) = (15, 0)
| Conn (FIN-WAIT, TIME_WAIT) = (0, 0)
| Conn (accept, not accept) = (56, 0) (estab, fail) = (37, 0)
| Conn (abandon, expire) = (0, 3) Resets = 13 Bad cksm = 0
| (rxbadseg, rxooseg, txrexmits) = (0, 53855, 157)
| SYN cache overflow = 0 (rxcookie, rxbadcookie) = (0, 0)

Evan
- hooleylistCirrostratusHi Evan,
- kev_245_28249NimbostratusThanks for the reply. A couple more questions:
- hooleylistCirrostratusI would guess the uneveness has something to do with the hashing algorithm that determines which TMM receives the packets and the specific type of traffic that's being sent to an IP:port which doesn't have a listener defined. I'm not sure exactly why that would happen though. If you'd like to find out more about this, you could open a case with F5 Support.
- kev_245_28249NimbostratusOk will do. what do you think about the ratio? Am I correct in saying:
