Description: This object is the MAC information that learnt or removed in the monitored device. It can consists of more than one MAC information in the object. This object is in the format of '...'. Each cell consists of 14 octets in the format of ''. is the reason type of MAC address changed and have size of 1 octet. It only supports the following values. 1 - MAC learnt. 2 - MAC removed. is the vlan number that correspond to the MAC address in MAC address table and has size of 2 octet. is the MAC address and has size of 6 octets. is the MAC address type and has size of 1 octet. It only supports the following values. 0 - Unknown 1 - Learnt 2 - Config dynamic 3 - Config static 4 - Blackhole 5 - Security 6 - 802.1x 7 - MAC authentication 8 - Voice VLAN 9 - WAPI is the index of the interface where the MAC address is learnt or removed and has size of 4 octets.

What is hh3cMACInfoTrapMsgExt?

This object carries the MAC address change data for the extended trap, packed as one or more 14-octet cells each describing an operation type, VLAN, MAC address, MAC type, and interface index. It extends the original hh3cMACInfoTrapMsg cell format by widening the ifIndex field to 4 octets, letting it represent interface indexes beyond the 16-bit range the non-extended trap supports. For example, a management station decoding this field on a chassis switch with large ifIndex values relies on the extended 4-octet ifIndex to correctly identify which of many linecards' ports the MAC change occurred on.
