Configures the slb failover. Specify:
• remote-ip-address—The remote
peer IP address.
•
local-ip-address—The address of a
local IP interface used for the failover
connection.
•
L4Port—The TCP port used for keep-
alives between the failover peers. The
default port is 1028.

configure slb global [ping-check | tcp-port-
check | service-check] frequency <seconds>
timeout <seconds>
Configures default health checking
frequency and timeout period. If the health
check frequency and timeout are not
specified for a specific node or VIP, the
global values are used. Specify one of these
service checkers:
• ping-check—L3-based pinging of the
physical node. Default ping frequency is
one ping generated to the node each 10
seconds. If the node does not respond to
any ping within a timeout period of 30
seconds (3 ping intervals), the node is
considered inoperable.
•
tcp-port-check—L4-based TCP port
open/close testing. Default values are 30
seconds for frequency and 90 seconds for
timeout.
•
service-check—L7-based
application-dependent checking. Default
values are 60 seconds for frequency and
180 seconds for timeout.
configure slb global ftp userid <userid>
password {encrypted} {<password>}
Configures default parameters for L7
service checking. If no password is
provided, you are prompted twice.
