  1. GTM V11 update Jing Lin 2012 12 March.

  2. Files change • Removed files: • /config/gtm/wideip.conf • /config/gtm/region.* • /config/gtm/topology.inc • New file: • /config/bigip_gtm.conf • /config/*partitions*/bigip_gtm.conf • Remain file: • /config/gtm/server.crt • /config/gtm/keyset-* ( dnssec zone) • /config/gtm/dsset-* (dnssec zone)

  3. Commands change • Removed: • Gtmparse • New: • tmsh /gtm • Esrapmtg, only for converting wideip.conf to bigip_gtm.conf • Tmsh show cm device-group gtm • Remain: • bigip_add, gtm_add, iqdump

  4. Gui CHANGE • Add prober pools menu • Add prober pool configurations when manage server/dc • Change old “Statistics Collection Server ” to prober pool • Add iquery, prober pool info in gtm statistics

  5. GuiCHANGE- continue • Add dns profile when creating listener Need create dns profile first in ltm part. • Add route advertisment when creating listener.

  6. Function change • New function dnsexpress. • See another ppt for dnsexpress detail: • dns_zone_transfer_and_dnsExpress.pptx • New function DNS6to4 • New function IP Anycast • Now can use dnsirule command to control/maintain/manipulate dns packets. – v11.0 read-only;v11.1 read-write, create/modify rr

  7. Change ON CREATING SYNC GROUP? • No change! • Still bigip_add, gtm_add… big3d_install

  8. What change to user? • Cant use gtmparse –l to load wideipconfig • Use tmsh load sys configgtm-only partitions allinstead • Use tmsh save sys configgtm-only partitions all

  9. Architecture change • GTM LB AND PERSISTENCE moved into tmm now. So now gtm can get high performance. (GTM CMP now) • This help reduce gtmd’s load and increase its stability.

  10. Change on sync logic IQSyncer TMSH BIG3D BIG3D GTMD GTMD MCPD MCPD BIG-IP B BIG-IP A

  11. Change on sync logic • Not use timestamp of wideip.conf now • Use commit-id timestamp • Also can see commit-id timestamp in iqdump • No more sync the whole wideip.conf file. Use mcp message instead now.

  12. Prober pool • Use prober pool override GTM election logic of big3d. • Note will not override gtm election logic of gtmd. So you will still see the same result on which gtmd will be responsible. Need be careful when checking logging. • Prober pool can be applied to DC, server (not vs)

  13. If customer upgrade to v11, and get strange behavior, first check big3d version which is running. • You can find them in iquerymessage, • In ihealth check gtm_module.xml

  14. Thanks
