When a stack unit reloads, the stack unit generates a syslog message similar to the following:
SYSLOG: <9>3d21h52m57s : ICX6610-24P Router Stack: unit 3 Reload u3 in 10 sec due
to 3/2/6 port problems. reason: lose one nbr
SYSLOG: <9>0d00h08m59s : ICX6610-48 Router Stack: unit 2 U3 detects stack port
problem. will reload u2: one directional CPU to CPU: u2 --> u3, one directional CPU
to CPU: u2 --> u4,
When the entire stack reloads, the active controller generates a syslog message similar to the
following:
SYSLOG: <9>0d00h12m07s : ICX6610-48 Router Stack: "stack stack-port-resiliency 3"
is configured. Active u3 reloads the stack in 5s. reason: no CPU to CPU: u1 -x- u4,
no CPU to CPU: u2 -x- u4, no CPU to CPU: u3 -x- u4,
SYSLOG: <9>0d00h12m28s : ICX6610-24P Router Stack: "stack stack-port-resiliency 3"
is configured. Active u1 reloads the stack in 5s. reason: 1: 1/2/1 (T0) --->
2/2/6 (T1) *** error: one-way 2: 1/2/2 (T0) ---> 2/2/7 (T1) *** error:
one-way 3: 1/2/3 (T0) ---> 2/2/8 (T1) *** error: one-way 4: 1/2/4 (T0) ---

error: one-way one directional CPU to CPU: u2 --> u4,
PHY calibration errors in stack ports of the ICX 6610
On every boot initialization, an ICX 6610 device performs PHY calibration on the 40 Gbps and 4 x10
Gbps stack ports. Sometimes, this calibration is incorrect, and results in CRC errors and link drops on
a port. FastIron IronWare detects the calibration errors and, by default, recovers the port by
recalibrating it. You can use the no snmp-server enable traps nlp-phy-40g command to disable this
recovery of incorrectly calibrated stack ports. To re-enable the default behavior of recalibrating the
incorrectly calibrated stack ports for recovery, use the snmp-server enable traps nlp-phy-40g
command.
Syslog messages for PHY calibration
On boot initialization, an ICX 6610 device in a stack performs PHY calibration on its 40 Gbps and 4
x10 Gbps stack ports, and generates a syslog message. The following syslog message example
shows the calibration of all 16 ports (4 PHY with 4 lanes for each) on an ICX 6610 stack unit.
SYSLOG: <14>0d00h02m52s : ICX6610-48 Router System: Port init success Stack unit 3

If any stack port in an ICX 6610 device has the PHY Tx or Rx CMU (voltage) reaching a threshold
value of 31 and the port is re-calibrated, the stack unit generates a syslog message similar to the
following:
SYSLOG: <14>0d00h08m49s : ICX6610-48 Router System: Port init success Stack unit 2
