7210 SAS-MXP, R6, R12, S, SX, T BASIC SYSTEM
CONFIGURATION GUIDE RELEASE 22.9.R1
System management
If a sync-if-timing reference is linked to a source port that is operationally down, the port is no longer
qualified as a valid reference. Depending on the platform used, either SFP or Fixed copper ports can be
used as a reference.
Note:
• On the 7210 SAS-T, 7210 SAS-Mxp, 7210 SAS-R6, and 7210 SAS-R12, all three timing
references can be enabled at the same time. In other words, it is allowed to specify the syncE
and PTP references simultaneously. Only syncE and BITS are allowed as a reference.
• The 7210 SAS-Sx 1/10GE (standalone) only supports the first and second parameters and it
is allowed to specify the syncE and PTP references simultaneously.
• The7210 SAS-S 1/10GE (standalone) and 7210 SAS-Sx 10/100GE (standalone) only support
first and second parameters.
The no form of this command reverts the reference order to the default values.
Default
bits1 bits2 ref1 ref2 ptp (7210 SAS-Mxp)
ref1 ref2 ptp bits1 bits2 (7210 SAS-T)
ref1 ref2 (7210 SAS-S 1/10GE (standalone))
ref1 ref2 ptp (7210 SAS-Sx 1/10GE (standalone) and 7210 SAS-Sx 10/100GE (standalone))
bits1 ref1 ref2 ptp (7210 SAS-R6 and 7210 SAS-R12)
Parameters
first
Specifies the first timing reference to use in the reference order sequence.
second
Specifies the second timing reference to use in the reference order sequence.
third
Specifies the third timing reference to use in the reference order sequence. This parameter
is supported only on 7210 SAS-T, 7210 SAS-Mxp, 7210 SAS-R6, and 7210 SAS-R12
devices.
fourth
Specifies the fourth timing reference to use in the reference order sequence. This
parameter is supported only on 7210 SAS-T, 7210 SAS-Mxp, 7210 SAS-R6, and
7210 SAS-R12 devices.
fifth
Specifies the fifth timing reference to use in the reference order sequence. This parameter
is supported only on 7210 SAS-T and 7210 SAS-Mxp devices.
ptp
Specifies that PTP must be used as a timing reference.
