IP Commands show ip interface
OmniSwitch CLI Reference Guide March 2011 page 10-99
Device The type of device bound to the interface:
•
unbound —No device is bound to the interface.
•
vlan —The VLAN ID that is bound to the interface.
•
EMP —The Ethernet Management Port is bound to the interface.
•
Loopback —A loopback interface is configured for testing.
•
GRE tunnel —GRE tunnel is configured for the interface.
•
IPIP tunnel —IPIP tunnel is configured for the interface.
Configured through the ip interface command.
Note that the GRE tunnel and IPIP tunnel devices are supported only
on the OmniSwitch 10K switches.
Encapsulation Displays the IP router encapsulation ( eth2 or snap ) that the interface
uses when routing packets. Configured through the ip interface
command.
Forwarding Indicates whether or not IP forwarding is active for the interface
(
enabled or disabled ). Configured through the ip interface command.
Administrative State Administrative state of the IP interface ( enabled or disabled ), which is
independent of the state of the underlying device. Configured through
the
ip interface command.
Operational State Indicates whether or not the interface is active ( up or down ).
Operation State Reason Indicates why the operational state of the interface is down:
•
unbound —No device is bound to the interface.
•
device-down— Device bound to the interface is down.
•
admin-down— The admin state of the interface is down.
•
no-such-device— Device does not exist.
•
no-router-mac— No MAC address available for the interface.
•
tunnel-src-invalid— The source IP address of the tunnel is invalid.
•
tunnel-dst-unreachable— The destination IP address of the tunnel
is not reachable.
Note that the tunnel-src-invalid and tunnel-dst-unreachable Opera-
tional State reasons are supported only on the OmniSwitch 10K
switches. These two reasons are only applicable for the GRE tunnel
and IPIP tunnel device types.
Note that Operational State Reason field is only included in the dis-
play output when the operational state of the interface is down .
Router MAC Switch MAC address assigned to the interface. Note that each interface
assigned to the same VLAN shares the same switch MAC address.
Local Proxy ARP Indicates whether or not Local Proxy ARP is active for the interface
(
enabled or disabled ). Configured through the ip interface command.
Maximum Transfer Unit The Maximum Transmission Unit size set for the interface. Configured
through the
ip interface command.
Primary (config/actual) Indicates if the interface is the configured and/or actual primary inter-
face for the device (VLAN, EMP, Loopback). If the actual status is set
to
yes and the config status is set to no , the interface is the default inter-
face for the VLAN. Configured through the ip interface command.
