Faildetect - Enterasys Matrix DFE-Gold Series Configuration Manual

Understanding Transparent Web Cache Balancing (TWCB)
Mode
Router command, Cache Server Configuration mode: Matrix(rw)‐>Router(config‐twcb‐cache)#.
Usage
The application method defaults to a check of service availability on port 80. This check can be
overridden by the web‐cache group configuration of http‐port using the http‐port command.
Example
This example sets the failure detection type to the ping method for cache server 186.89.10.51:
Matrix(rw)->Router(config)#ip twcb wcserverfarm s1Server
Matrix(rw)->Router(config-twcb-wcsfarm)#cache 186.89.10.51
Matrix(rw)->Router(config-twcb-cache)#faildetect type ping

faildetect

Use this command to specify the TWCB cache server up or down status detection method
parameter values.
Syntax
faildetect [ping-int seconds] [ping-retries number] [app-int seconds
app-retries number]
Parameters
ping‐int seconds
ping‐retries number

app‐retries number
Defaults
If no parameter is specified, all parameters remain unchanged.
Mode
Router command, Cache Server Configuration mode: Matrix(rw)‐>Router(config‐twcb‐cache)#.
Example
This example sets the failure detection type to the ping method for cache server 186.89.10.51 and
sets the ping interval to 7 and the number of ping retries to 3:
Matrix(rw)->Router(config)#ip twcb wcserverfarm s1Server
Matrix(rw)->Router(config-twcb-wcsfarm)#cache 186.89.10.51
Matrix(rw)->Router(config-twcb-cache)#faildetect type ping
Matrix(rw)->Router(config-twcb-cache)#faildetect ping-int 7 ping-retries 3
