hirmaAddrBTBlock

Module: PRIVAT-MultiLAN-Switch-MIB

OID (symbolic): PRIVAT-MultiLAN-Switch-MIB::hirmaAddrBTBlock

OID (numeric): 1.3.6.1.4.1.248.2.1.1.4.2

Node type: OBJECT-TYPE

Description: Offers a block of address information.
This list of the address entries is not
lexicographically ordered.

Byte (n*10)  m |     State
****************************************
Byte m=0        | reserved
Byte m=1        |
    Bit 0..2; 4 | reserved
    Bit 3       | MultiLAN Switch MAC address
    Bit 5       | static, entered by mgmt
    Bit 6       | aged out
    Bit 7       | valid
Byte m=2        | interface card, where the
                | address appeared.
Byte m=3        | reserved
Byte m=4..m=9   | MAC address

Where n is the number of address
entries. So, each address block is
aligned to n*10 Bytes.

What is hirmaAddrBTBlock?

Returns a block of learned MAC address entries in a fixed 10-byte-per-entry binary format, encoding flags (static, aged-out, valid) and the interface card where each address was seen. Network management tools use this alongside hirmaAddrBTAddr to bulk-retrieve the switch's full address table rather than polling one entry at a time.
