HI, Has anyone successfully implemented auto-vlan with 3Com switch 4500G? I am using the following tunneling attributes: ATTRIBUTE Tunnel-Type 64 integer has_tag ATTRIBUTE Tunnel-Medium-Type 65 integer has_tag ATTRIBUTE Tunnel-Private-Group-Id 81 string has_tag VALUE Tunnel-Type VLAN 13 VALUE Tunnel-Medium-Type TMT802 6 The node is declared as followed: ##IT Dell Inspiron 4000 laptop -- DHCP 00-09-5b-61-52-0d Auth-Type := Local, User-Password == "00-09-5b-61-52-0d" Tunnel-Medium-Type = TMT802, Tunnel-Private-Group-id = 2, Tunnel-Type = VLAN, Although my radius access request shows that the access has been granted and the VLAN 2 assigned, the switch 4500G does not open its port on VLAN 2. I changed the tunnel-medium-type between TMT802 and 802, but that did not change anything. I am currently doing auto-vlan with 3com 4400 with the same configuration and it is working like a charm. Any idea why the switch does automatically adjust? Any beginning of information is welcome.
