Usage Guidelines
You must have administrator privileges to issue this command.
To create any virtual service, you must specify the IP address and port to which Internet clients connect
and the protocol (TCP or UDP) to be used. For a layer 7 service, you also specify the class of application
that the VIP supports, either http for regular web trafÞc, or https for SSL session persistence.
You may optionally specify either of the following:
¥ A virtual router ID (VRID) for the VRRP class for this service
¥ A VLAN for this service
If you enable VRRP (with the enable vrrp command):
¥ You must assign every virtual service to a VRRP class. You specify the class for a service with the
vrid parameter.
¥ Every unique VIP must belong to a single VRRP class. Thus, if you use the same VIP for different
services (each with a different combination of port and protocol), all those services must be assigned
the same VRID.
¥ If gateway mode is also enabled, you must ensure sure every server responds to VIPs in a single
VRRP class. That is, all services that use a particular server must be in the same VRRP class.
IP address The virtual IP address of the service.
VRID number The VRID of the VRRP class for the service; a number between 1 and 255.
vlan tag number The VLAN tag for the service.
port number The port the service uses to answer requests.
tcp Specifies the TCP protocol.
udp Specifies the UDP protocol.
http Specifies that the service supports regular web traffic.
https Specifies that the service supports SSL session persistence.
