New Features in BIG-IP Version 17.1.3.1
See the following articles for details of software lifecycle.
BIG-IP version 17.1.3.1 introduces the following new features for LTM:
A new database variable is now available, allowing you to lock the current DAGv2 tables:
tmsh modify sys db dag.dagv2.pgs value $(tmctl -d blade -q -L 1 tmm/daglib_dagv2_pgs -s table)
tmsh modify sys db dag.dagv2.hsbs value $(tmctl -d blade -q -L 1 tmm/daglib_dagv2_hsbs -s table)
tmsh modify sys db dag.dagv2.mirror.pgs value $(tmctl -d blade -q -L 1 tmm/daglib_dagv2_mirror_pgs -s table)
tmsh modify sys db dag.dagv2.mirror.hsbs value $(tmctl -d blade -q -L 1 tmm/daglib_dagv2_mirror_hsbs -s table)It is important to store both standard and mirrored tables due to the internal workings of DAG. Additionally, this change requires the CMP state to remain consistent with the state defined within the tables, an essential consideration in cases such as blade failure. A tmm restart is required after locking the new dag tables.
This functionality is also applicable to SP DAG in LSN NAPT deployments.
This improvement extends the functionality of the cmp_dest utility functions to output the distribution of the IP addresses between a blades and tmms when given as inputs:
--subnets [list of subnets] address pools for traffic distribution profiling,
e.g.: 10.10.127.9/24,10.11.0.0/32
--excluded_subnets [list of subnets] address pools excluded from profiling.
i.e. discontinuity or holes in pools in --subnets argument.
--blades [comma separated list of populated blade slots starting from 1]
e.g.: 1,2,3. May be used instead of --cmp_state option
--config [configuration file] use arguments from a configuration file
For a given DAG configuration, the cmp_dest utility can now report the distribution of IP addresses within LSN blocks across the tmm instances on the system.
Support for HTTP1.1 is added which support the host header field. The OCSP requests for auth should now use HTTP1.1 version.
