The default setting of AGETIME_LOW/HIGH provides 300 seconds aging time. Aging time is based on the
following equation:
{AGETIME_HIGH,AGETIME_LOW} X (# of MAC entries in the memory X 800 µsec). Number of MAC entries = 4 K.

SE_OPMODE – Search Engine Operation Mode
Protocol filtering mode
0 – Inclusive (Default)
1 – Exclusive
1 – Disable report MAC address deletion
0 – Report MAC address deletion (MAC address is deleted from MCT after
aging time) (Default)
1 – Disable aging logic from removing MAC during aging
0 – MAC address entry is removed when it is old enough to be aged (Default)
However, a report is still sent to the CPU in both cases, when bit [2] = 0
1- Enable RSVP Packet trapping. IP Multicast also needs to be enabled for
this function.
0- Disable RSVP Packet trapping. (Default)
1 - Report ARP packet to CPU
0 - No ARP packet reporting (Default)
Disable MCT speed-up aging
1 – Disable speed-up aging when MCT resource is low.
0 – Enable speed-up aging when MCT resource is low. (Default)
Slow Learning
1– Enable slow learning. Learning is temporary disabled when search
demand is high
0 – Learning is performed independent of search demand (Default)
Reserved. Must be 0.
