Interfaces General

Note The following variables are not supported by all interfaces: PortVsan, Port Mode Admin and Oper, Admin Speed, and FailureCause.
Item     Description
Description

Alias name for the interface as specified by a network manager.

PortVsan

VSAN ID to which this interface is statically assigned.

Admin

The port mode configured by the user. If the user configured the port as auto, then the port initialization scheme determines the mode of the port. Modes are:

  • E Port - In expansion port mode, an interface functions as a fabric expansion port. This port may be connected to another E port to create an Inter-Switch Link (ISL) between two switches. E ports carry frames between switches for configuration and fabric management.
  • F Port - In fabric port mode, an interface functions as a fabric port. This port may be connected to a peripheral device (host or disk) operating as an N port.
  • FL Port - In fabric loop port mode, an interface functions as a fabric loop port. This port may be connected to one or more NL ports (including FL ports in other switches) to form a public arbitrated loop.
  • TL Port - In translative loop port mode, an interface functions as a translative loop port. It may be connected to one or more private loop devices. TL port mode is specific to Cisco MDS 9000 family switches and have similar properties as FL ports.
  • TE Port - In trunking E port mode, an interface functions as a trunking expansion port. It may be connected to another TE port to create an Extended ISL (EISL) between two switches. TE ports are specific to Cisco MDS 9000 family switches.
  • SD Port - In SPAN destination port mode, an interface functions as a switched port analyzer (SPAN). The SPAN feature is specific to switches in the Cisco MDS 9000 Family. It monitors network traffic that passes though a Fibre Channel interface.
  • ST Port - In the SPAN Tunnel port mode, an interface functions as an entry point port in the source switch for the RSPAN Fibre Channel tunnel. The ST port mode and the remote SPAN (RSPAN) feature are specific to switches in the Cisco MDS 9000 Family. When configured in ST port mode, the interface cannot be attached to any device, and thus, cannot be used for normal Fibre Channel traffic.
  • Fx Port- Interfaces configured as Fx ports are allowed to operate in either F port or FL port mode. The Fx port mode is determined during interface initialization depending on the attached N port or NL port. This administrative configuration disallows interfaces to operate in any other mode—for example, preventing an interface to connect to another switch.
  • B Port - While E ports typically interconnect Fibre Channel switches, some SAN extender devices, such as Cisco's PA-FC-1G Fibre Channel port adapter, implement a bridge port model to connect geographically dispersed fabrics.
Oper

The current operating mode of the port.

Admin

The port speed configured by the user.

Speed

Operational speed.

Admin

The desired state of the interface.

Oper

The current operational state of the interface.

FailureCause

The cause of current operational state of the port.

WasEnabled

If true, this port successfully completed a link initialization.

LastChange

When the interface entered its current operational state. If the current state was entered prior to the last re-initialization of the local network management subsystem, then this value is N/A.
