syncd#SDK: [SAI_UTILS.WARNING] mlnx_sai_utils.c[1685]- check_attribs_metadata: Not implemented attribute SAI_SWITCH_ATTR_AVAILABLE_SNAT_ENTRY (vendor data not found)
swss#orchagent: :- NatOrch: Failed to get the SNAT available entry count, rv:-196608

Steps to reproduce the issue:

  1. sudo config nat feature enable
  2. sudo config nat add static basic -nat_type snat 192.168.0.1 192.168.1.1
  3. sudo sonic-db-cli COUNTERS_DB hgetall "COUNTERS_GLOBAL_NAT:Values"

Describe the results you received:

1. 
2. Max limit is reached for NAT entries, skipping adding the entry.
3. {'MAX_NAT_ENTRIES': '0', 'TIMEOUT': '600', 'UDP_TIMEOUT': '300', 'TCP_TIMEOUT': '86400'}

Describe the results you expected:

1. 
2. Static Nat Entry Added.
3. {'MAX_NAT_ENTRIES': '4096', 'TIMEOUT': '600', 'UDP_TIMEOUT': '300', 'TCP_TIMEOUT': '86400'}

@adyeung could you check if BRCM would be interested in maintaining NAT feature and fix this CLI

adyeung commented 12 months ago

@dgsudharsan since Spectrum 3 doc claims support for NAT, pls work the SAI team to implement SAI_SWITCH_ATTR_AVAILABLE_SNAT_ENTRY and SAI_SWITCH_ATTR_AVAILABLE_DNAT_ENTRY
