Commands in the interface configuration mode
This section describes commands that you can call up in the Interface configuration mode.
● The commands are only available with layer 3
● Enable routing to use VRRP.
● You can only use VRRP in conjunction with VLAN interfaces.
● VRRP only supports IPv4. If you want to use IPv4 and IPv6, use VRRPv3
Note
The commands are only available with layer 3 and only in conjunction with VLAN interfaces.
In the VRRP Router configuration mode, enter the interface command to change to this
mode.
Commands relating to other topics that can be called in the Interface configuration mode can
be found in the relevant sections.
● If you exit the Interface configuration mode with the exit command, you return to the VRRP
Router configuration mode.
● If you exit the Interface configuration mode with the end command, you return to the
Privileged EXEC mode.
7.3.4.1
spanning-tree
Description
With this command, you configure the various properties of the spanning tree function:
● With the cost option, you configure the port costs used to calculate the lowest-cost path.
● With the disable option, you disable the interface for the spanning tree function.
● With the link-type option, you configure the connection status of the following network
segment. The following settings are possible:
– point-to-point – the interface communicates with precisely one network component
– shared - the interface is connected to more than one network component
● With the portfast option, you enable the PortFast function on the interface. The interface
is connected to an end device and can therefore ignore the waiting time before changing
to Forwarding mode.
● With the port-priority option, you configure the priority of the interface for negotiating
a spanning tree configuration.
Requirement
You are in the Interface Configuration mode.
The command prompt is as follows:
324
SCALANCE W770/W730 acc. to IEEE 802.11n Command Line Interface
Configuration Manual, 09/2017, C79000-G8976-C324-08
