Our ISE server return VLAN names for various user vlans as based on user identity. Some of them doesn’t apply to certain area. On those switches, there is no corresponding vlan. We want a certain vlan host all users in such area. Say HR user log in to a switch in branch, the HR vlan doesn’t exist. I want switch put user in employees instead. How can I put a vlan with 2 name or merge 2 vlans?

Why change VLANs at all? What is the use-case? I don't think what you are describing is possible. If you must change VLANs, then I would put the NADs that do not have the HR VLAN into a separate NAD group and make policies accordingly so ISE doesn't push the HR VLAN to those switches.

hi @JianfengWang5009 , ISE is not capable of creating/merge vlans within a switch , the ISE is capable only to assign vlans with base on your authentications.

I agree with @ahollifield , I don't believe what you are trying to achieve is possible. End of the day, ISE just returns attributes via RADIUS, it doesn't really dictate anything on the switches in this case. One thing you can potentially do which is quite common is to configure a parking VLAN on all the switches, and then on ISE you associate that parking VLAN to the default authorization rule. By doing so if the user/machine does not match any of the specific authorization rules, they will hit the default rule and will be placed into the parking VLAN.

@JianfengWang5009 I agree with all responded.
Perhaps, you may use VLAN groups but you need to configure them on the switches. For example, on a switch, configure the following:
vlan 10
name Employees
vlan group HR vlan-list 10
vlan group Marketing vlan-list 10

@JianfengWang5009 As shown above, VLAN groups should help and most of Cisco catalyst switches will take the VLAN assignment from ISE and apply it as a VLAN group or a VLAN. Check out this blog -- 802.1x VLAN User Distribution (VLAN Group) -- the CCIE journey
