Troubleshooting Call Processing Alarms
Feature Server Both Links Down—Call Processing (12)
The Feature Server Both Links Down alarm (critical) indicates that both links to the feature server are
down. The primary cause of the alarm is that the link interface hardware is broken. To correct the
primary cause of the alarm, check the link interface hardware and, if necessary, reconnect or replace.
The secondary cause of the alarm is the that the link interface state is operationally down. To correct the
secondary cause of the alarm, check the operational state of the link.
To check the operational state of the interface links and the physical condition of the interface links,
proceed as follows:
Step 1
Check status of the interfaces using one of the methods below (If the
kstat
command in Example 1 does
not provide an output, try the ndd commands in example 2.):
Example 1:
mssol-ca0-a# kstat hme:0:hme0:link_up
module: hme instance: 0
name: hme0 class: net
link_up 1
mssol-ca0-a# kstat qfe:0:qfe0:link*
module: qfe instance: 0
name: qfe0 class: net
link_duplex 2
link_up 1
mssol-ca0-a# kstat qfe:0:qfe0:ifspe*
module: qfe instance: 0
name: qfe0 class: net
ifspeed 100000000
Example 2:
# ndd -set /dev/eri instance 0
# ndd -get /dev/eri link_status
1
# ndd -get /dev/eri link_mode
1
# ndd -get /dev/eri link_speed
1
Step 2
Verify the following settings:
•
Duplex should be 1 (full duplex)
•
Link_up or link_status should be 1 (operational)
•
Link mode should be 1 (no auto negotiation).
Step 3
Verify call agent and switch interfaces are both set to full duplex no auto negotiation.
Step 4
Verify link speed is hard-coded to the same value on both ends.
Step 5
Check for any errors pertaining to the interface in /var/adm/messages* file.
Step 6
Check operational status of ethernet interface(s) on switch side as follows:
admin up / line protocol up
