Virtual servers
BIG-IP® Reference Guide 4-79
The following example shows the two commands used to enable mirroring
for virtual server v1 on the FTP control and data ports:
b virtual v1:21 mirror conn enable
b virtual v1:20 mirror conn enable
Displaying information about virtual servers
You can display information about all virtual servers in your configuration,
or you can display information about one or more specific virtual servers.
To display information about all virtual servers in your
configuration
Use the following syntax to display information about all virtual servers
included in the configuration:
b virtual show
To display information about one or more virtual servers in
your configuration
Use the following syntax to display information about one or more virtual
servers included in the configuration:
b virtual <virt_ip>:<service> [...<virt_ip>:<service>] show
The command displays information such as the nodes associated with each
virtual server, the nodes’ status, and the current, total, and maximum
number of connections managed by the virtual server since the BIG-IP was
last rebooted.
Setting a user-defined netmask and broadcast
The default netmask for a virtual address, and for each virtual server hosted
by that virtual address, is determined by the network class of the IP address
entered for the virtual server. The default broadcast is automatically
determined by the BIG-IP, and it is based on the virtual address and the
current netmask. You can override the default netmask and broadcast for a
network virtual address only.
All virtual servers hosted by the virtual address use the netmask and
broadcast of the virtual address, whether they are default values or they are
user-defined values.
To set a custom netmask and broadcast
If you want to use a custom netmask and broadcast, you define both when
you define the network virtual server:
b virtual <virt_ip>[:<service>] [vlan <vlan_name> disable | enable] [netmask <ip>]
[broadcast <ip>] use pool <pool_name>
Note
The BIG-IP calculates the broadcast based on the IP address and the
netmask. In most cases, a user-defined broadcast address is not necessary.
