Symptom: standby delay timer is not accurate in that the standby delay timer does does not take correct effect if set to >254 seconds For example, when configured standby delay minimum timer to 300, HSRP becomes active in 46 second after the interface come up. When configured reload timer to 600, HSRP becomes active in 88 seconds after the interface comes up. Essentially a modulus of 255 is being applied to the value. So it will work as expected up to a value of 254 then go back to zero seconds when a value of 255 is entered. Conditions: When the standby delay timer is used to delay the startup of HSRP on an interface up or a reload.
