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) in NPG mode and are automatically
set to F (fabric port) or E (extended port) in Fabric Services. The maximum number
of buffer-to-buffer (BB) credits available is fixed at 16.
WWN, FC-ID Factory-provided world-wide name (WWN) of FC port (in hexadecimal) that
uniquely identifies the port on the switch (not user-configurable) and the unique
FC port ID (24-bit in hexadecimal) received from an FC switch in the fabric after a
successful login.
Last clearing of
“show interface”
counters
Elapsed time since the interface counters displayed in show interfaces output were
last cleared.
Statistics:
BBCR_FrameFailur
es
Number of link resets due to frames lost during buffer-to-buffer credit recovery
(BBCR) period.
BBCR_RRDYFrame
Failures
Number of link resets due to multiple Receiver Ready (R_RDY) frames received
during the credit recovery period.
