The LTM devices LTM3 and LTM2 have four Traffic Groups defined with approximately the sar of failover objects defined in each group.

-

Traffic Groups A and C have Default Device set to LTM1

-

Traffic Groups Band D have Default Device set to LTM2.

-

Traffic Groups B and C do NOT have Auto Failback enabled. Traffic Groups A and D have Auto Failback

enabled with a timeout value of 60 seconds.

-
