I have configured a VPC between a pair of Nexux 9Ks 93120TX Have enabled MST on both switches and now getting an inconsistency check error with global port type

 

Both switches are configured the same 

spanning-tree port type edge bpduguard default

Still getting mis-match on consistency check?

Hello Roger,

 

I recommend you to read this "We recommend that you set all the vPC peer link interfaces to the STP network port type so that Bridge Assurance is automatically enabled on all vPC peer links. We also recommend that you do not enable any of the STP enhancement features on VPC peer links." https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5000/sw/layer2/502_n1_1m/b_Cisco_n5k_layer2_config_gd_rel_502_N1_1/Cisco_n5k_layer2_config_gd_rel_502_N1_1_chapter8.pdf

Thank you for your reply

 

they are set as Network 


interface port-channel100
description VPC_PEER_LINK
switchport mode trunk
spanning-tree port type network
vpc peer-link

 

 

Try removing the "edge default" command and it should come up. Here is a link with more details.
