Chapter 16 Monitoring XgOS 311
■ the magenta text shows another link in the overall IB path. These entries show
how the IB path flows through the various points in the Oracle Fabric
Interconnect Fabric Board. Entries are ordered in pairs to show the ingress and
egress points in the Fabric Board’s leaf switches/chips.
■ the cyan text shows the I/O module that is the other end of the IB path, which in
this example is a Fibre Channel card in slot 3 which is terminating the vHBA on
the IB path.
Fields in the command output show information about the performance of, and
any errors on, the links in the overall IB path. The following table provides a brief
description of the fields. Complete documentation for these fields can be found in
the InfiniBand Architecture Release 1.2.1, July 2007, Final Release.
Field Description
lid/port The Local Identifier and port that the IB path is using.
width/speed The link width and speed.
SymErrors The Symbol Error Counter, which show the total number of minor link errors detected on
one or more IB lanes.
LnkRcov The Link Error Recovery Counter, which shows the total number of times the Port Training
state machine has successfully complete a link-error recovery.
LnkDwnd The Link Downed Counter, which shows the total number of times the Port Training state
machine has not successfully completed a link-error recovery, and as a result, has put the
link into “down” state.
RxErrs The Port Receive Errors Counter, which shows the total number of packets received on the
port but contained errors.
RxSwErr The Port Receive Switch Relay Errors Counter, which shows the total number of packets
received on the port that were discarded because they could not be forwarded by the switch
relay.
TxDisc The Port Transmit Discard Errors Counter, which shows the total number of outbound
packets discarded by the port because the port is down or congested.
TxPkts The Port Transmit Packets Counter, which shows the total number of packets transmitted on
all Virtual Lanes from the port.
RxPkts The Port Receive Packets Counter, which shows the total number of packets received on all
Virtual Lanes on the port, including packets containing errors, and excluding link packets.
