Diagnostic Tests
SCIP supports T1 diagnostics which can assist equipment installers in isolating T1 network
problems. Installers initiate diagnostic tests using CLI commands via a terminal connection to the
SCIP front panel Craft port or through a Telnet connection. Diagnostics consist of self-tests,
loopback tests and checks as follows:
•
T1 Network Line Loopback Test
•
T1 Self Test with Loopback
•
T1 Self Test
•
T1 Payload Loopback Test
Diagnostic Tools
•
SCIP supports the standard traceroute application which is used to determine the path an IP
packet follows through the network. It is a useful tool for diagnosing IP connectivity problems.
Traceroute is invoked by the
trace-rte
command.
•
System messages (SYS MSG) are useful in debugging failures. The last 100 system
messages can be viewed with the
show log sysmsg
command.
•
When the SCIP is configured for LAN-X mode, the
diags lanx
command can be used to
send different sized test packets to the remote SCIP which loops them back to the sender. This
diagnostic check is independent of IP and does not use ICMP (ping).
•
Network Statistics displays information about the current TCP socket connections, such as the
local or remote IP address, send and recieve window sizes, state, etc. To show the Network
Statistics, type:
show netstat
.
Alarms
SCIP supports standard T1 network alarm reporting which informs users about catastrophic or
impaired line conditions. Alarms can be enabled and configured to display at user-specified
intervals. Alarms disabled by the user will be masked and the front panel ALM led will not light
when the particular alarm event occurs. Supported T1 alarms are as follows:
•
Out Of Frame (OOF) alarm
•
Loss of Signal (LOS) alarm
•
Alarm Indication Signal (AIS)
•
Bipolar Violation (BPV) alarm
•
Cyclic Redundancy Check (CRC) error alarm
•
Received Yellow (RYEL) alarm event
•
Low Average Density (LAD) alarm
SNMP Traps
SCIP can generate SNMP traps on various events, and employs a more reliable method for sending
them to as many as four trap hosts. By storing traps and verifying connectivity before sending, trap
delivery is greatly improved in the event of temporary network outages. Supported traps are:
•
Cold Start trap
•
LinkUp/Down traps for ethernet0, serial0, serial1, and modem0 (if so equipped)
•
Up/Down traps for etherswitch port1 and etherswitch port2
•
Contact Sense trap for Start/Stop; Contact Sense trap for Active/Clear
•
MACL Violation trap; Authentication Failure trap
