4. SYN Cookie: LTM Configuration

Hi Runo,

It seems that article you pointed out should be updated. It is partially correct, in v12 default value for this DB Key was 2999 originally, but for last v12 versions this changed to 16k. I paste below an example for you from a v12.1.6 device:

# tmsh sho sys soft

-------------------------------------------------

Sys::Software Status

Volume Product Version Build Active  Status

-------------------------------------------------

HD1.1  BIG-IP 12.1.6 0.0.9   yes complete

# tmsh list sys db pvasyncookies.virtual.maxsyncache all-properties

sys db pvasyncookies.virtual.maxsyncache {

  default-value "16000"

  scf-config "true"

  value "16000" <==!!

  value-range "unsigned integer min:193 max:65535"

}

# tmsh modify sys db pvasyncookies.virtual.maxsyncache value 500000

01070049:3: Db variable pvasyncookies.virtual.maxsyncache's value [500000] out of its minimum 193 and maximum 65535 range.

Regards
