>how to incorporate all this information in freeradius directory >(configuration)?
Have a look at the dictionary.3com in freeradius distribution. If they are not there, ask 3com for an updated dictionary file and post it here. If it's OK it will be included in the distribution and you can replace dictionary.3com in your installation. >I don't understand what "26, 43, 2" mean. 26 means VSA attribute, 43 means that vendor is 3Com and 2 is the id of that attribute so 3Com device can know what attribute it is (name VLAN-Name or more likely 3Com-VLAN-Name, is for humans).
