The question about gre protocol type supported by SONiC #1131
Description
Description
I have tested two gre protocol type (0x6558, 0x88be) in mirror session, and found that only 0x88be is passed and 0x6558 failed. The error message is due to SAI_STATUS_ATTR_NOT_SUPPORTED_0.
(Please see the detail attached to below section)
My question is that does SONiC support gre type 0x6558 or shoud use 0x88be in mirror?
I saw that the gre type 0x6558 is used in below link.
https://github.com/Azure/sonic-swss/blob/master/swssconfig/sample/mirror.json
PS:
- 0x6558: Trans Ether Bridging [RFC1701]
- 0x88be: Encapsulated Remote SPAN (ERSPAN)
- ASIC vendor: Broadcom
Steps to reproduce the issue:
- docker exec swss swssconfig /root/mirror.json (use gre_type 0x6558)
- ip route add 2.2.2.0/24 via 10.10.1.1 dev Ethernet0
- check syslog and orchagent process
