Connection Management Problems
C.9.3.10 Connection Up/Down/Reroute Failed
Connection up/down/reroute diagnostics failures with switch error
Step 1 Query the connection information from the user_connection table for that connection
Step 2 Query the connection information from the switch CLI and verify the connection status (dspcon,
dspchan etc.)
Execute the up/down/reroute diagnostics from switch CLI and verify the results matches with what was
reported in Cisco MGM(upcon, dncon, rrtcon)
Defect Information
1. Capture selnd output
2. Copy all the cmsvr logs from /opt/svplus/logs directory
3. Capture the user_connection table query output from Cisco MGM DB for the given end point (if the
request is not an addition request)
4. Capture the switch CLI output for the up/down/reroute diagnostics on the same connection
Possible alternative workaround:
1. Check the status of the connection and clear any alarms due to line/port issues (adding loopback,
correcting the physical cable issues by verifying the physical port connections etc.). After the
connection comes up and is in clear state, rerun the up/down/reroute diagnostics again.
2. Verify the connection status to find if the connection is already down, when trying to do a down
operation or the connection is already up when trying to do an up operation.
3. Note that connection reroute might take the connection to FAIL state for a while, if it is rerouted.
C.9.3.11 Connection Trace Failures
Connection trace returns a failure.
Step 1 Make sure the connection is not in Fail state, connection trace does not work on failed connections,
Cisco MGM does not block this request as well.
Query the connection information from the user_connection table for that connection
Step 2 Query the connection information from the switch CLI and verify the connection status (dspcon,
dspchan etc.)
Execute the connection trace diagnostics from switch CLI and verify the results matches with what was
reported in Cisco MGM(conntrc, dsptrcbuffer)
Defect Information:
1. Capture selnd output
2. Copy all the cmsvr logs from /opt/svplus/logs directory
3. Copy all the cmgrd logs from /opt/svplus/logs directory
4. Capture the user_connection table query output from Cisco MGM DB for the given end point (if the
request is not an addition request)
5. Capture the switch CLI output for the trace diagnostics on the same connection
