Vlan2 DOWN Not connected
Table 20
Command output
Field Description
Vlan-interface10 current state
The physical state of a VLAN interface:
•
DOWN ( Administratively )—The administrative state of the VLAN
interface is down, because it has been shut down with the
shutdown
command.
•
DOWN—The administrative sate of the VLAN interface is up, but
its physical sate is down. The VLAN corresponding to this interface
does not contain any physical port in the UP state (possibly because
the ports are not well connected or the lines have failed).
•
UP—Both the administrative state and the physical state of the
VLAN interface are up.
Line protocol current state
The link layer protocol state of a VLAN interface:
•
DOWN—The protocol state of the VLAN interface is down.
•
UP—The protocol state of the VLAN interface is up.
Description
The description string of a VLAN interface.
The Maximum Transmit Unit
The MTU of a VLAN interface.
Internet Address is
192.168.1.54/24 Primary
The primary IP address of the interface is 192.168.1.54/24. This
information is displayed only if the primary IP address is configured for
the interface.
Internet Address is 6.4.4.4/24 Sub
The secondary IP address of the interface is 6.4.4.4/24. This
information is displayed only if a secondary IP address is configured
for the interface.
IP Packet Frame Type
The IPv4 outgoing frame format.
Hardware address
The MAC address corresponding to a VLAN interface.
IPv6 Packet Frame Type
The IPv6 outgoing frame format.
Last clearing of counters
The time when the
reset counts interface vlan-interface
command was
last used to clear the interface statistics.
Never
indicates the
reset counters interface
command has never been
used on the interface since the device's startup.
The brief information of interface(s)
under route mode
Brief information about Layer 3 interfaces.
Link: ADM - administratively down;
Stby - standby
ADM—The interface has been administratively shut down. To recover
its physical state, perform the
undo shutdown
command.
Stby—The interface is operating as a standby interface. To see the
main interface, use the
display standby state
command.
Protocol: (s) - spoofing
If the network layer protocol state of an interface is shown as UP, but its
link is an on-demand link or not present at all, its protocol attribute
includes the spoofing flag (an s in parentheses).
