Tiara Routers
Routing with Tiara 1400 Router for NxT1
Troubleshooting
T1
A comprehensive view of an individual T1 can be viewed using the following command:
TIARA 1400> display module configuration t1 [t1 number]
T1 2 is ENABLED
Alarm Hierarchy: TRUE,
Yellow Alarm: DISABLE
Framing: ESF, LineCode:B8ZS, ClockSource:LINE, LineMode:CSU, LBO:0 db

The Tiara 7030 was able to initiate a remote loopback request to the Tiara 1400 in the lab environment. In the event this does not work an administrative T1 loopback can be configured from the command line.
TIARA 1400> test t1 [t1 number]
TIARA 1400/test/t1> loopback line
Sending Local Line Loop Up for T1 Interface 8.....
Local Loop State: Loop Up Loop Type: Line
To turn the loopback down use the keyword no:
TIARA 1400/test/t1> no loopback line
sending Local Line Loop Down for T1 Interface 8.....
local Loop State: Loop Down Loop Type: None

Frame Relay
A comprehensive diagnostic view of the operational state of a frame relay interface and the configured PVCs can be viewed using the following command:
TIARA 1400> display interface bundle [bundle name]
The sample output is suppressed due to the length. The output can be reduced by specifying an individual PVC on a frame relay interface.
TIARA 1400> display interface bundle [bundle name] pvc [dlci]
The command above would be most useful when checking the status of an individual PVC on the bundle.
LMI statistics for a particular frame relay interface can be viewed using the following command:
TIARA 1400> display fr lmistats [bundle name]

System
The Tiara 1400 has an event log that can be custom configured to filter specific events:
TIARA 1400> display event_logs
The event log stores up to 1000 events. Additonal events will force the oldest to be discarded.
The event logs can filter specific event types. All of the different filtering options will not be outlined in this document. However, the command syntax is noted below:
TIARA 1400> configure term
TIARA 1400/configure> event filter [options]
