Hi,
I would like to ask about vlan 4094 in nexus, as far I know that vlan is belong to internal usage of nexus. I have change the internal usage vlan to another range, but after I rebooted the nexus I still saw vlan 4094 in internal usage. Is there another way I could use vlan 4094? because in my current production environment I am using vlan 4094.
Thank you

The changes you mentioned should have helped convert vlan 4094 into a regular vlan.
Can you please post the following outputs-
show accounting log
show logging log
show vlan internal usage
show version

Rajesh,
Just to add on I just tried the above test on my pod for this issue and issue is seen.
Here are the steps I did:-
http://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/5_x/nx-os/layer2/configuration/guide/Cisco_Nexus_7000_Series_NX-OS_Layer_2_Switching_Configuration_Guide_Release_5-x_chapter4.html
N7K-1#
1-system vlan reserve changed to different range:-
N7K-1# conf t
N7K-1# system vlan 2000 reserve
This will delete all configs on vlans 2000-2127. Continue anyway? (y/n) [no] y
N7K-1# Copy run to start and rebooted the box.
2- After the box was rebooted:-
show system vlan reserved
system current running vlan reservation: 2000-2127 >> its updated.
3-
N7K-1# show vlan internal us
VLANs DESCRIPTION
------------------- -----------------
2048-2111 Multicast
2000-2015 Online Diagnostic
2016-2047 ERSPAN
2112 Satellite
2113 Fabric scale
2000-2127,4094 Current >> dont know why it is still showing here.
4- Not able to create the vlan 4094.
N7K-1(config)# vlan 4094
^
invalid vlans (reserved values) at '^' marker.
N7K-1(config)# vlan ?
<1-1999,2128-4093> VLAN ID 1-3967 or range(s): 1-5, 10 or 2-5,7-19
Might be something I am missing here ....

Thanks Inayath for testing it in the lab. I see that 4094 is always going to be reserved as per some internal notes. I will file a documentation bug to have the L2 switching config guide updated to indicate that 4094 will not be available for customer use.

Updated an older bug CSCtz64509 to track this. Bug may not be visible in the public domain yet but just FYI that we will be tracking it.
