sticky weirdness (CSM)

neo · ‎08-09-2010

HI All,

Can someone explain this ? I don’t understand why the IWSS servers appear to be ‘sticky’ to themselves

This is an extract from the config

sticky 200 netmask 255.255.255.255 address source timeout 10

static client source 10.253.21.56 real 10.253.21.1

static client source 10.253.21.57 real 10.253.21.2

static client source 10.253.21.58 real 10.253.21.3

static client source 10.253.21.59 real 10.253.21.6

static client source 10.253.21.60 real 10.253.21.7

static client source 10.253.21.61 real 10.253.21.8

static client source 10.253.21.176 real 10.253.21.4

static client source 10.253.21.177 real 10.253.21.9

and this is what the sticky table looks like

cor-lln-civ-6509-01#sh mod csm 7 sticky group 200

group sticky-data real timeout

it appears that servers also are initiating connections to whatever vserver uses this sticky group, so you see servers laodbalancing to other servers.
