As a switchport must belong a VLAN (the default VLAN or a configured VLAN), all MACaddress learned on a switchport are associated with a VLAN. For this reason, the Q-Bridge MIB isused for MAC address query. Moreover, specific to MAC address query, the MAC address indexesdot1dTpFdbTable only for a single forwarding database, while dot1qTpFdbTable has two indices —VLAN ID and MAC address — to allow for multiple forwarding databases and considering that thesame MAC address is learned on multiple VLANs. The VLAN ID is added as the first index so thatMAC addresses are read by the VLAN, sorted lexicographically. The MAC address is part of the OIDinstance, so in this case, lexicographic order is according to the most significant octet.Table 55. MIB Objects for Fetching Dynamic MAC Entries in the Forwarding DatabaseMIB Object OID MIB Descriptiondot1dTpFdbTable .1.3.6.1.2.1.17.4.3 Q-BRIDGE MIB List the learned unicastMAC addresses on thedefault VLAN.dot1qTpFdbTable .1.3.6.1.2.1.17.7.1.2. 2 Q-BRIDGE MIB List the learned unicastMAC addresses on non-default VLANs.dot3aCurAggFdb Table .1.3.6.1.4.1.6027.3.2. 1.1.5 F10-LINK-AGGREGATION -MIBList the learned MACaddresses of aggregatedlinks (LAG).In the following example, R1 has one dynamic MAC address, learned off of port TenGigabitEthernet 1/21,which a member of the default VLAN, VLAN 1. The SNMP walk returns the values for dot1dTpFdbAddress,dot1dTpFdbPort, and dot1dTpFdbStatus.Each object comprises an OID concatenated with an instance number. In the case of these objects, theinstance number is the decimal equivalent of the MAC address; derive the instance number by convertingeach hex pair to its decimal equivalent. For example, the decimal equivalent of E8 is 232, and so theinstance number for MAC address 00:01:e8:06:95:ac is.0.1.232.6.149.172.The value of dot1dTpFdbPort is the port number of the port off which the system learns the MAC address.In this case, of TenGigabitEthernet 1/21, the manager returns the integer 118.Example of Fetching MAC Addresses Learned on the Default VLAN Using SNMP----------------MAC Addresses on Force10 System------------------Dell#show mac-address-tableVlanId Mac Address Type Interface StateSimple Network Management Protocol (SNMP) 801
