Description of the problem

OSN3500 Configuration New Low Order Service Reporting Error

failed!cmd:0x802f error:0x97e2 NSERR_CFG_NO_PATH_TO_ALLOC

Processing

1. Issue the command :cfg-get-lowxc-capacity to query the current cross-board low-order resource utilization.

#0x90258:cfg-get-lowxc-capacity:9;.

Explanation of the meaning of the field:

MAX-CAPACITY: Low-order cross-capacity of the current cross-board in G. The low-order cross-capacity here is 5G.

MAX-VC4-NUM: The number of VC4s of the source and the host of the low-order chip of the current crossover board. The number of VC4s here is 32.

LEFT-SRC-VC4-NUM: The number of source VC4s remaining for the current cross-single board low-order chip. The source VC4 remaining here is 3.

LEFT-DST-VC4-NUM: the number of remaining host VC4s for the current cross-single board low price chip. Here, there are 3 remaining host VC4s.

LEFT-DST-VC12-NUM: The number of remaining host VC12s for the current cross-single low price chip. Here, there are 548 remaining host VC12s. Since the service configuration will only go from 1 to N (1 <= N <= MaxVc12Num), all commands do not need to list the number of remaining source VC12s.

LEFT-DST-VC3-NUM: The number of remaining host VC3s for the current cross-single board low cost chip. Here, there are 3 remaining host VC3s. Since the service configuration will only go from 1 to N (1 <= N <= MaxVc3Num), all commands do not need to list the number of remaining source VC3s.

To configure the VC12 service, ensure that the number of remaining source VC4s and remaining host VC12s is not 0.

To configure the VC3 service, ensure that the number of remaining source VC4s and remaining host VC3s is not 0.

2. Through the query result, you can know that the number of low-order chip-out VC4 (LEFT-DST-VC4-NUM) are all occupied. If you configure another host for a low-order service that is not the same as the host (slot-optical-port-VC4) of any currently configured low-order service, an error is reported.

3. How to verify that the remaining source VC4s are really all used?

To count all the cross-services and SNCP-configured services of this network element, count how many VC4s are used by each single board and optical port, and the sum is the number of VC4s used.

4. you can refer to 3 for how to verify the remaining host VC3 and the remaining host VC12 usage.

Root Cause

Insufficient low-order resources

Solutions

Optimize services or replace high-capacity low-order cross-capacity cross veneers.
