This is the Cisco fibre element management MIB module.
It covers:
- Cisco extension to the interface MIB ( IF-MIB )
- Contains all the groups from FIBRE-CHANNEL-FE-MIB
  relevant to Cisco fabric.
- Other features specific to Cisco fabric.

This MIB supports all the port types defined by the
textual convention FcPortTypes. In addition it also
supports Nx_port, where Nx_port can be either N_port or
NL_port. The FC standards define Interconnect_Ports
to be E_ports or B_Ports.

This MIB supports Port Channel ports. Port 
Channel port is a single logical port, which contains 
multiple physical ports as its members. Presently only 
E_ports can be a member of Port Channel port.

In addition it provides GigE and port channel information 
for all the Gigabit Ethernet (GigE) ports in the fabric.
