Sets the ETHER1 interface (100BASE full duplex/AUTO).
After changing the switch setting, you have to reboot the unit (power off
and back on) to enable the new setting.

Table 3-3 Alarm Issuance and Clear Conditions
Initial state
Cleared The RFU-CPU detects LOCALM
or TRSELALM three times each
for more than 10msec.
LOCALM (local oscillator alarm)
occurs if the local oscillator lost
synchronization.
TRSELALM
(transmission/reception
switchover SW failure) occurs if
the transmission state continues
for more than 1sec.
IFU-CPU detects a RFU-IFU
communication error (monitoring
response).
Cleared Communication error among the
S-CPU, D-CPU and U-CPU.
No response to polling for 3sec
L2SW setting failure
If setting failed four times (once
for transmission and 3 times for
retransmission)
Cleared The S-CPU detects a
S-RFU-CPU communication
error.
No response to polling four
times (once for transmission
and 3 times for retransmission)
Issued PHY link down 3 times each for
100msec.
Issued PHY link down 3 times each for
100msec.

Description
Issued when: Cleared when:
The RFU-CPU detects
no LOCALM or
TRSELALM three
times each for more
than 10msec.
Synchronization is
recovered.
Only by a reset.
IFU-CPU is cleared by
a single RFU-IFU
communication
(monitoring response).
Cleared by a single
response.
No recovery
Cleared by a single
response.
Recovered from PHY
link down 3 times each
for 100msec.
Recovered from PHY
link down 3 times each
for 100msec.
