show interfaces fibrechannel Command Description
Field Description
Information:
Fibrechannel 0/0 is down,
FC link is down
Administrative state of the Fibre Channel interface (up/no shutdown or down/
shutdown) and operational state of the FC link (up or down).
Pluggable media present,
SFP+ type
Pluggable optic is inserted in the port or not, and the SFP+ optic type.
Wavelength Wavelength of the inserted optic.
SFP+ receive power Power received on SFP+ optic.
Interface index Index number of FC port.
MTU Maximum transmission unit on interface (not user-configurable; fixed at 2148
bytes).
LinkSpeed Configured transmission speed of the FC port when the port link is down or
current speed when the port link is up. Valid link speeds are: auto (port
autosenses speed of peer FC port), 2G, 4G, or 8G.
Port type, Max BB credits The FC port type is fixed at N (end node port). The maximum number of
buffer-to-buffer (BB) credits available is fixed at 16.
