GTAC update:
-------------------------------------------------------------------------------------------------------------------
ln the L3 Hardware table, the multicast entries are reaching the hardware limit.
In this case you can choose one of the two options:
1. If you are not using multicast traffic you can disable IGMP snooping. If you disable it then it floods the multicast traffic like broadcast.
2. Change the forwarding mode to group-vlan mode.
The command is the following:
configure forwarding ipmc lookup-key group-vlan
configure forwarding ipmc compression group-table

I would recommend the second option. After that the Hardware L3 Table full logs should not appear.
