downstateflush string Flush all active transactions on all services bound to the virtual server when the state changes to DOWN.
disableprimaryondown string When a virtual server goes DOWN, remain the primary virtual server in the HA pair so clients continue to connect.
insertvserveripport string Insert the virtual server IP address and port in the request header.
vipheader string Name of the HTTP header used to insert the virtual server IP and port.
authenticationhost string FQDN of the authentication virtual server to which the user is redirected for authentication.
authentication string Whether authentication is enabled for the virtual server.
authn401 string Whether to use HTTP 401-based authentication instead of redirect-based.
authnvsname string Name of the authentication virtual server for 401-based authentication.
icmpvsrresponse string How the NetScaler responds to ICMP ping requests sent to the VIP.
rhistate string Route health injection state. Whether to advertise the route to the VIP via dynamic routing when the server is UP.
newservicerequest integer Number of requests to accept on a new service before distributing traffic to all bound services. Range 0-100.
newservicerequestunit string Unit for the newservicerequest parameter.
newservicerequestincrementinterval integer Interval in seconds between successive increments for new service request rate. Range 0-3600.

redirurl string Redirect URL string configured on the virtual server.
curstate string Current operational state of the virtual server.
effectivestate string Effective state of the virtual server considering all factors.
status integer Current status of the virtual server. 1 indicates UP.
lbrrreason integer Reason for the last load balancing redirection.
totalservices integer Total number of services bound to the virtual server.
activeservices integer Number of active (UP) services bound to the virtual server.
statechangetimesec string Time when the virtual server state last changed, in date-time format.
