protocol based VLAN not working

protocol based VLAN not working

Configuration done to perform packet filter based on "Protocol Based VLAN", traffic was captured via mirroring and I see packets are not forwarding to correct VLAN.

Configuration for port 7:
Summit48si:18 # show port 7 vlan info
Name VID Protocol Addr Flags Proto Ports
Payload 333 10.10.20.130 /25 ------f------- mnet 11/20
OM_Node 332 10.10.20.50 /28 v-----f------- ANY 10/20
OM_RPP 192 192.168.0.2 /24 ------f------- mnet 11/20
Internal 46 ------------------ -------- p1 7/36

Mirror Results:
1) Using "enable mirror add port 7 vlan "Payload" I just see traffic to network 10.10.20.128/25. There is no traffic from network 10.10.20.128/25

2) Using "enable mirror add port 7 vlan OM_Node" I am able to see traffic from network 10.10.20.128/25, but traffic is been received by different VLAN than expected which proves mnet protocol based is not working for some reason!

Additional Information:
- It happens for swiches Summit 48si running EOS "7.8.4.1 patch1-r4" & EOS "7.8.4.1".
- "enable multinet" is configured
- "create protocol mnet" is configured

Someone can help me uinderstand what is wrong?
Thanks in advance,
Wanderley Benacchio Junior

Hi Wanderley, thanks for your confirmation. Just to confirm since tagged has more priority than protocol-based.

It seems to be related to the protocol filter configuration.

What does the configuration for the 'mnet' protocol filter look like?

Hi Wanderley,

Is the port receiving/sending that traffic configured as "tagged" to the protocol-based vlan?
