Hi , We have a Switch Extreme X670G2 that cant learn mac because of full table, it appears the next log:
29-Nov-2019 04:58:54 Failed to add vlan translation entry on port 1:12 oldvlanid: 2271 newvlanId: 2271
29-Nov-2019 04:58:54 Failed to add egress vlan translation entry on port 1:12 due to "Table full".
But the table is not full because it could learn more macs with other vlans, also the vlan doesnt have any translate configuration

Hi!
You may be experiencing a situation where the MAC address table (FDB) is full in some aspects. In most switches (not just Extreme), the FDB is populated using a “hash tree”. This means that for some MAC and VLAN combinations the tree can become congested even if the number of addresses is not at the max limit.
What does “show fdb stats” say?
