While creating the master end of a cross connect between a RPM_PR & AXSM I am getting the following error:


addcon 8 0 50 5 1 -slave 4700918100000000016444472000000107730100.0.50 -lpcr 4000 -rpcr 4000 -lscr 4

000 -rscr 4000

ERR: Error in traffic parameters (dcmp)


The RPM sub interface configuration is:


interface Switch1.1 point-to-point

description Cross connect to AXSM

ip address 192.168.1.1 255.255.255.252

no ip route-cache

pvc 0/50

oam-pvc manage

encapsulation aal5snap

!

switch connection vcc 0 50 master remote

pcr 4000

scr 4000

rpcr 4000

rscr 4000


I am not sure why I am getting this error, can anyone help with this?

It appears that the PNNI and AXSM DBs are out of synch. Could you please do ----- "dspcon 12:2.1:9 15 148" , on the PXM

and check if this connection exists ?

I am not sure which connection you are referring to, but the problem I was having was a result of a missing statement.


interface Switch1.1 point-to-point

description Cross connect to AXSM

ip address 192.168.1.1 255.255.255.252

no ip route-cache

pvc 0/50

vbr-nrt 1696 1696 100 <-- was missing

oam-pvc manage

encapsulation aal5mux ip

!

switch connection vcc 0 50 master local raddr xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

pcr 4000

scr 4000

rpcr 4000

rscr 4000

rmbs 100


The question I have now is: what PVC encapsulation type should I use on this subinterface to terminate a PVC coming from FRSM configured for frame forwarding?


I am currently using aal5mux ip but the PVC is showing failed.

A couple of things...


On the AXSM you set the Service Type = 5 nrt-VBR.1, however on the RPM you have not set the corresponding parameter. Example IOS command in PVC config mode is:

vbr-nrt


If you do not set the QoS param on the RPM, it will default to UBR with 100% PCR bandwidth, hence "error in traffic parameters" which refers to both the QoS value and the Cell Rates.


If you select vbr-nrt on the RPM the corresponding AXSM QoS is nrt-vbr.3 - option 7.


Be sure to match the cell rates exactly. Cell rates entered in PVC config mode are Kbps for output-PCR and output-SCR and cells for output-MBS.


Values entered in switch conn config mode are cells!
