Configuring a Health-Check Ping
The health-check ping will be associated with an ESI group, along with servers, so that controller will send ICMP
echo requests to each server in the group and mark the server down if the controller does not hear from the server.
The health-check parameters used in this example are:
l Frequency—30 seconds. (The default is 5 seconds.)
l Retry-count—3. (The default is 2.)
l Timeout—2 seconds. (The default is 2 seconds.)
Use these CLI commands to configure a health-check ping method:
esipingprofile_name
frequencyseconds
retry-countcount
timeoutseconds
Configuring ESI Servers
Here are the ESI server CLI configuration tasks:
l Configure server mode to be NAT.
l Configure the trusted IP address (the server IP address to which packets should be redirected).
l To redirect to a different port than the original destination port in the packet, configure an alternate destination
port.
Use these CLI commands to configure an ESI server and identify its associated attributes:
esiserverserver_identity
dportdestination_tcp/udp_port
mode{bridge|nat|route}
trusted-ip-addrip-addr [health-check]
Configure an ESI Group, Add the Health-Check Ping and ESI Servers
Use these CLI commands to configure an ESI server group, identify its associated ping health-check method, and
associate a server with this group:
esigroupname
pingprofile_name
serverserver_identity
Using the ESI Group in a Session Access Control List
Use these CLI commands to define the redirection filter for sending traffic to the ESI server.
ip access-listsessionpolicy
useranysvc-httpredirectesi-groupgroupdirectionboth
