show network-interface

The show network-interface command shows the following information about all network interfaces on the appliance.

• The type of interface: Ethernet, VLAN, aggregate, or other. The other interface type refers to network interfaces that you cannot configure. Examples of other interface types include gre0, ip6tnl0, lo, sit0, and usb0. Not all appliances have all of these other interface types.
• The name of the interface.
• The configured goal operational state of the interface.
• The operational state of the interface. States are Up, Down, Unknown, Dormant, Not present, or Lower Layer Down.
• The primary address for the interface: IP version, address, and netmask.
• The physical (MAC) address of the interface.
• The maximum transmission unit (MTU), or largest packet, size that can be sent or received on the interface.
• Statistics about received transactions:
  • The amount of data, in bytes, that was received successfully on the interface, which includes MAC-framing.
  • The number of packets that were received successfully on the interface and were passed to the network layer.
  • The number of packets that were not received because of errors in the packet or in the hardware.
  • The number of received packets that were not in error but were not passed to the network layer because of resource constraints.
• Statistics about transmitted transaction:
  • The amount of data, in bytes, that was transmitted successfully on the interface, which includes MAC-framing.
  • The number of packets that were transmitted successfully on the interface.
  • The number of packets that were not transmitted because errors on the network or in the hardware.
  • The number of packets that were not transmitted because the network layer generated packets faster than the physical network can accept them.
