there the reserved vlan range for nx-os
3968 to 4047 and 4094 |
Internally allocated |
These 80 VLANs and VLAN 4094 are allocated for internal device use. You cannot create, delete, or modify any VLANs within the block reserved for internal use. |
does it show up in your show vlan or show int trunk anywhere ?
system maybe using it for something

Thank you for you answer.
I see this vlan only in command "sh mac adress table". Any else i can't found him. Mac address cross with active vlan:
# sh mac address-table address 002a.6xx.xxxx
Legend:
* - primary entry, G - Gateway MAC, (R) - Routed MAC, O - Overlay MAC
age - seconds since last seen,+ - primary entry using vPC Peer-Link
VLAN MAC Address Type age Secure NTFY Ports/SWID.SSID.LID
---------+-----------------+--------+---------+------+----+------------------
* 802 002a.xxxx.xxxx static 0 F F Router
* 4040 002a.xxxx.xxxx static 0 F F Router

I see that same VLAN (4040) but I see it in the "sh vpc consistency-parameters global" output under the "Allowed VLANs" section. It is on one side of the vPC but not the other and i think that is what is causing the Type 2 inconsistency status.
Type-2 consistency status : failed
Type-2 inconsistency reason : SVI type-2 configuration incompatible
I realize the "reason " states 'SVI config incompatible" but all of my SVI's are consistent across the two vdc's. Could this mystery VLAN be causing the Type 2 inconsistency?
