EDIRECTION
Web cache redirection uses the TCP or UDP port number to redirect client requests to a
target device (or group of devices). Web cache redirection transparently redirects traffic
to web cache devices or to proxy servers and firewalls located in a demilitarized zone.
There are two ways to configure web cache redirection:
• Transparent mode SLB (described earlier in this chapter)
• Flow redirection

EDIRECTION
Flow redirection examines traffic and redirects it based on the following criteria:
• IP source address and mask
• IP destination address and mask
• Layer 4 port
enable slb vip [<vipname> | all] svcdown-reset Enables the svcdown-reset configuration. If
enabled, the switch sends TCP RST to
both the clients and the node, if the node
associated with this VIP completely fails a
ping-check, port-check, or service-check.
Otherwise, the connections to the node are
left as is, and are subject to connection
reaping if idle for longer than the
treaper-timeout configured on the SLB port.
The default setting is disabled.
show slb 3dns members Disables the current connection information
between the switch and all the 3DNS
queriers.
show slb failover Disables the SLB failover configuration and
status.
unconfig slb vip [<vipname> | all] service-check Disables and removes the service check
configuration.
