VDX6740 - PBR match interface Te 1/0/2(version 7.3.0)

Hello Experts,

I have created the below PBR but it is not working as per expectation.

Configuration :

===========

rbridge-id 1

route-map PBR_TEST permit 10

match interface te 1/0/3

set ip next-hop 192.168.31.2

exit

ip route 10.10.10.0/24 192.168.21.10

arp 192.168.21.10 0000.0000.2110 interface te 1/0/3

arp 192.168.31.2 0000.1234.5678 interface te 1/0/4

exit

interface te 1/0/2

ip address 192.168.11.1/24

ip policy route-map PBR_TEST

exit

interface te 1/0/3

ip address 192.168.21.1/24

exit

interface te 1/0/4

ip address 192.168.31.1/24

exit

Outputs:

=======

extreme01# show route-map PBR_TEST

Interface Te 1/0/2

ip policy route-map PBR_TEST permit 10

set ip next-hop 192.168.31.2

Policy routing matches: 0 packets Note: No counters available

extreme01# show ip route-map PBR_TEST

route-map PBR_TEST

seq 10

match interface Te 0/3

set ip next-hop 192.168.31.2

Above both outputs contradict as one shows a match condition and the other does not.

Packet test result :

==============

packet injected from Te 1/0/3 with ipv4_src 192.168.11.11 & ipv4_dst 10.10.10.1 , Packet coming out of the interface Te1/0/3 but as per PBR it should come out from Te 1/0/4

how does the switch check the Match condition here as Te 1/0/3 doesn’t have PBR on it, so when traffic ingress from Te 1/0/3 how it will go to PBR for Match validation?

so in this case match interface criteria is not supported?

As we are applying PBR at interface Te 1/0/2 and matching interface Te 1/0/3,
so how Te 1/0/3 will send the traffic for PBR inspection if it's not applied on it?
