'show mac' doesn't display the FDB entries learnt on VXLAN tunnel port

[praveenraja1]

Description

With VXLAN running in P2MP tunnel mode, the FDB entries that are learnt on tunnel ports are not displayed in the 'show mac' output.

They are present as BGP evpn entries and are present in ASIC H/W.

Also looking at the ASIC_DB and APPL_DB, we can see the FDB entries here as well, so its the case of CLI scripts not parsing and displaying the entries correctly.

ASIC_STATE:SAI_OBJECT_TYPE_FDB_ENTRY:{"bvid":"oid:0x260000000007b0","mac":"9C:2B:BF:02:02:89","switch_id":"oid:0x21000000000000"}

"VXLAN_FDB_TABLE:Vlan30:a8:17:56:53:33:b0":{"type":"hash","value":{"remote_vtep":"1.1.1.1","type":"dynamic","vni":"3000"}

Steps to reproduce the issue

1. Config VXLAN in P2MP mode
2. Send traffic over tunnel, so that FDBs are learnt on tunnel ports.
3. 'show mac' and see that entries are not displayed
