## from root cli ##

host:~# ibportstate
Usage: ibportstate [-d(ebug) -e(rr_show) -v(erbose) -D(irect) -G(uid) -s smlid -V(ersion) -C ca_name -P ca_port -t(imeout) timeout_ms] <dest dr_path|lid|guid> <portnum> [<op>]
supported ops: enable, disable, reset, speed, query

Examples:

ibportstate 3 1 disable # by lid
ibportstate -G 0x2C9000100D051 1 enable # by guid
ibportstate -D 0 1 # (query) by direct route
ibportstate 3 1 reset # by lid
ibportstate 3 1 speed 1 # by lid

host:~# ibportstate 2 18 disable
Initial PortInfo:
# Port info: Lid 2 port 18
LinkState:.......................Active
PhysLinkState:...................LinkUp
LinkWidthSupported:..............1X or 4X
LinkWidthEnabled:................1X or 4X
LinkWidthActive:.................4X
LinkSpeedSupported:..............2.5 Gbps
LinkSpeedEnabled:................2.5 Gbps
LinkSpeedActive:.................2.5 Gbps

After PortInfo set:

# Port info: Lid 2 port 18
LinkState:.......................Down
PhysLinkState:...................Disabled

Alternate way of doing this from 'admin' login is as follows:

Confirm if the IB port is on CORE / LEAF2 switch, and keep its GUID handy for the below command:

admin@chassis-name[xsigo] set diagnostics ib-link-state guid <GUID of internal switch> <port> down/up
