Connection Management Problems
C.9.4.4.3 Cmgrd—Addition/Modification Errors. Provisioning a Connection Results in a Switch Error "Requested cell rate
(lscr/lpcr or rpcr/rscr ) is too high"
Related key index entries: cmgrd, cell rate
During a connection Addition/Modification request it is possible that the port the connection is being
SET on, has no more resources available to accept the traffic parameters that the current Snmp SET is
requesting, at this point the Switch will reject the request with the above error.
Step 1 For the user endpoint check the user port on the CLI via the command "dsppnportrsrc" this will indicate
the resource available per port
Step 2 Check the Switch TSG EDCS-235791, section 1.3.4 for further information on how to debug this issue.
Step 3 If the failure is not happening on a user endpoint port, and instead on an Intermediate port (i.e. for
Multi-Segment connections) then find out the local and remote endpoint feeder trunk ports (This can be
done easily by using the Network Topology GUI). On the CLI check the "dsppnportrsrc" for these feeder
trunk ports.
Defect Information—If after checking that the ports have enough bandwidth to add these connections
and still the error is being returned then save the cmgrd.log.
Possible alternative workaround—Freeing up resources on the port which needs the bandwidth to add
the connection, or lowering the traffic parameters value in the connection request.
C.9.4.4.4 Cmgrd—Addition Errors. Provisioning a Connection Results in a Switch Error "SPVC is not allowed on this interface"
Related key index entries: cmgrd, interface
During a connection Addition request it is possible that the user endpoint port that the connection is
being SET on, has an incorrect signalling configured on it, the above error is indicative of this condition.
For non trunking ports the signalling on the port cannot be "pnni".
Step 1 For the user endpoint port check the CLI for the following:
a. Interface is pnni port or controller port, check interface using "dsppnport"
b. Change port to UNI port. Before doing this make sure that no calls are going through this interface.
dnpnport <portID>
cnfpnportsig <portID> -univer uni30
Step 2 After changing the configuration retry the connection request.
Defect Information—Not applicable, as the above error has to be a Switch Configuration issue.
Possible alternative workaround—Indicated in the Investigation part.
