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. Terminology ELP : Exchange Link parameters EPP : Exchange Peer Parameters.
