[bdNOG] VLAN limitation in Nexus switch

Tue Oct 9 00:32:31 BDT 2018

Dear Mr Mahmood,

You need to be in MST mode to get the full 4000 by what it shows in doc
below

*3*
<http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus3000/sw/configuration_limits/503_u2_2/b_Nexus3K_Configuration_Limits_for_Cisco_NXOS_Release_503_u2_2.html#fnsrc_3>
507 VLANs in PVRST mode. 512 VLANs in RPVST mode where 507 are user-defined
VLANs, and 4,000 VLANs in MST mode

Hope it helps

Farhad
