<br>
I have some VLANs configured between certain ports on MLXe box (MLXe-16, 5.7.0e).<br>
All ports are in 'no route-only' mode. For example:<br>
<br>
<a href="mailto:telnet@lsr1-gdr.ki" target="_blank">telnet@lsr1-gdr.ki</a>(config)#show vlan 720<br>
<br>
PORT-VLAN 720, Name V720, Priority Level 0, Priority Force 0, Creation Type STATIC<br>
Topo HW idx : 65535 Topo SW idx: 257 Topo next vlan: 0<br>
L2 protocols : NONE<br>
Statically tagged Ports : ethe 7/1 ethe 9/5 ethe 10/6 ethe 11/6 ethe 13/3<br>
Associated Virtual Interface Id: NONE<br>
----------------------------------------------------------<br>
Port Type Tag-Mode Protocol State<br>
7/1 TRUNK TAGGED NONE FORWARDING<br>
9/5 TRUNK TAGGED NONE FORWARDING<br>
10/6 TRUNK TAGGED NONE FORWARDING<br>
11/6 TRUNK TAGGED NONE FORWARDING<br>
13/3 PHYSICAL TAGGED NONE FORWARDING<br>
Arp Inspection: 0<br>
DHCP Snooping: 0<br>
IPv4 Multicast Snooping: Enabled - Passive<br>
IPv6 Multicast Snooping: Disabled<br>
<br>
No Virtual Interfaces configured for this vlan<br>
<br>
<br>
<br>
As you may notice, passive multicast snooping is enabled on that VLAN.<br>
The problem is that multicast traffic is being switched by LP CPU,<br>
causing high CPU utilization and packet loss.<br>
<br>
It is clearly seen on rconsole:<br>
<br>
LP-11#debug packet capture rx include src-port me/6 vlan-id 720 dst-address 233.191.133.96<br>

**********************************************************************<br>
<br>
As far as I understand documentation that should not happen.<br>
The situation remains the same if I disable IGMP snooping.<br>
<br>
Any ideas/suggestions is kindly appreciated!<br>
<br>
Thanks in advance.<br>
