SAI_HOSTIF_TRAP_TYPE_ISIS is not supported

[odd22]

Hello,

We would activate IS-IS routing protocol on a Mellanox Spectrum switch. For that purpose, wee need to configure ISIS trap to get the ISIS packets instead let the switch forward them.
For that purpose, SAI defined the SAI_HOSTIF_TRAP_TYPE_ISIS to be able to configure trap action instead of default forward action.

Unfortunately, we got an error telling that SAI_HOSTIF_TRAP_TYPE_ISIS is not supported.

After looking to the code, it seems that SAI_HOSTIF_TRAP_TYPE_ISIS is defined, but no action are defined for ISIS, compared to LLDP or OSPF for example.

Can you add ISIS TRAP support ? ISIS packets are similar to LLDP (carry over Ethernet L2) and uses these mac addresses:

• L1 IS: 01:80:c2:00:00:14, All Level 1 Intermediate Systems Address
• L2 IS: 01:80:c2:00:00:15, All Level 2 Intermediate Systems Address
• All IS: 09:00:2b:00:00:05, All Intermediate System Network Entities address

Best Regards

Olivier
