may be changed)
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.
AUTO: AUTO

Table 3-3 Alarm Issuance and Clear Conditions
Item Initial state Issued when: Cleared when:
The RFU-CPU detects LOCALM or
TRSELALM three times each for
more than 10msec. The RFU-CPU detects no
LOCALM or TRSELALM
three times each for more
than 10msec.
LOCALM (local oscillator alarm)
occurs if the local oscillator lost
synchronization. Synchronization is
recovered.
TRSELALM
(transmission/reception switchover
SW failure) occurs if the
transmission state continues for
more than 1sec. Only by a reset.
1 RFU failure Cleared
IFU-CPU detects a RFU-IFU
communication error (monitoring
response). IFU-CPU is cleared by a
single RFU-IFU
communication (monitoring
response).
Communication error among the
S-CPU, D-CPU and U-CPU.
No response to polling for 3sec Cleared by a single
response. 2 IFU failure Cleared
L2SW setting failure
If setting failed four times (once for
transmission and 3 times for
retransmission) No recovery
3 Communication error
between RFU and IFU
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) Cleared by a single
response.
4 ETHER 1 link down Issued PHY link down 3 times each for
100msec. Recovered from PHY link
down 3 times each for
100msec.
5 ETHER 2 link down Issued PHY link down 3 times each for
100msec. Recovered from PHY link
down 3 times each for
100msec.
