The server Commands
specifies a broadcast message to a network; for example, x.x.x.255 is
the broadcast address for a Class C network.
For CIFS users , when an interface is created, deleted or marked
up/down, using the server_setup command, stop, then restart the
CIFS service in order to update the CIFS interface list.
<if_name> up
Allows the interface to receive and transmit data, but does not enable
the physical port. Interfaces are marked up automatically when
initially setting up the IP address.
<if_name> down
Stops data from being transmitted through that interface. If possible,
the interface is reset to disable reception as well. This does not
automatically disable routes using the interface.
<if_name> mtu=<MTUbytes>
Resets the maximum transmission unit (MTU) size in bytes for the
specified interface. By default, the MTU is automatically set
depending on the type of network interface card installed.
Regardless of whether you have Ethernet or Gigabit Ethernet, the
initial default MTU size is 1500 bytes. To take advantage of the
capacity of Gigabit Ethernet, the MTU size can be increased up to
9000 bytes if your switch supports jumbo frames. Jumbo frames
should be used only when the entire infrastructure, including client
NICs, supports them.
For UDP it is important that both client and server use the same MTU
size. TCP negotiates the MTU size when the connection is initialized.
The switch’s MTU must be greater than or equal to the host’s MTU.
Note: The MTU size specified here is for the interface. The MTU size
specified in server_netstat applies to the device and is automatically set.
<if_name> vlan=<vlanID>
Sets the ID for the virtual LAN (VLAN). Valid inputs are 0 (default)
to 4094. When a VLAN ID other than 0 is set, the interface only
accepts packets tagged with that specified ID. Outbound packets are
also tagged with the specified ID.
Note: IEEE 802.1Q VLAN tagging is supported. VLAN tagging is not
supported on ana interfaces.
