Our WCM is reporting 'SIA invalid packets are detected in service-node' on one of our WAEs (8541).
This alarm appears in WCM for few minutes and then vanishes. When I check alarm's description on WCM it says the following:
| Details: |
The System Monitor indicates that invalid SIA packets are seen in service-node. |
| Action: |
Execute show statistics service-insertion data-path to verify the service-node SIA packet statistics. There can be a network issue involved. |
However, when I execute 'show statistics service-insertion data-path' command, I see that amount of 'Number of packets with invalid socket buffer' is increasing, not SIA related counters. Also, what's SIA for WAAS? It is not EIGRP's SIA, isn't it?
Number of invalid packets dropped : 24
Number of packets with invalid IP : 0
Number of packets with invalid SMC type : 0
Number of packets with invalid SMC version : 0
Number of packets with invalid SWIRE header : 0
Number of packets with invalid SIA opcode : 0
Number of packets with invalid IP checksum : 0
Number of packets with invalid socket buffer : 24
Number of packets with invalid IP header : 0
Can't find any information about it. What does 'invalid socket buffer' means from WAAS perspective?
Is there anyone to quickly comment on this or do I have to go back to TAC with this question?
Thanks
Tim
