Command netif
The netif command is used to control and check the status of network
interfaces. The command syntax is:
netif [ open <ifname> | close < ifname> ]
Parameters for the netif command are described in Table 60 below.
Table 60 Parameters for Command netif
Parameter Use
No parameters Lists current status of all configured network
interfaces
open Opens the given interface
close Closes the given interface
ifname Name of interface to be opened or closed, for
example,
netif0
NOTE In spite of an issued close command, the interface may still remain open
if a service is using it. Closing will always be delayed by the specified
idle time (set in configuration).
Depending on the connection used, changing the state of a network
interface may take a while. For example, with the GSM modem, the
netif open command will take time for establishing the telephone
connection plus the time for network connection negotiation. This can
easily total over one minute.
Examples of netif command output are presented below:
