We have one 3750G, 12.2(35)SE5. I tried to configure "ip tacacs source-interface vlan2" but the swith won't take it. Even if I "write mem", it still doesn't show up in running configuration. The other same IOS switch does show up and tacacs works well. These two switches are trunked together. This is my first time to have this kind of issue. Is this a software bug? But the other same version switch doesn't have this issue.
Please help. Thanks in advance.
