Default behavior of Extreme switch when MAC table is full

[zeeshan_qadir]

Hi everybody

Let say we have a switch with mac table max address =45 . Assume mac table is full, let say another frame comes into the switch whose source mac-address and destination mac are not in the table.

1)Will switch overwrite the oldest mac entry with the source mac?
2) Will switch flood the frame out of all ports except for the port the frame was initially received because switch does not have the destination mac in its MAC table ?

Thanks,

Hi,

it will flood in hardware within that VLAN. Space in the MAC table is freed when a port goes down, a manual clear is performed in CLI or aging happens (no traffic seen for that MAC for the last aging period timer configured - 300sec by default).
