Inconsitency check in N2K acces port

[josecardenas]

Hi

We have configured a Fex port as acces port but the port no up becouse appear in suspended state, i think the problem is a vlan mistmach as appear in the consistence-parameter information but i not found in what part allow the correct vlan, the N2K are connected to 2 N5K, and 5K are connected to2  N7K

%ETHPORT-3-IF_ERROR_VLANS_SUSPENDED: VLANs 41 on Interface Ethernet101/1/48 are being susp

ended. (Reason: Vlan is not configured on remote vPC interface)

show vpc consistency-parameters interface e101/1/48

    Legend:

        Type 1 : vPC will be suspended in case of mismatch

Hello Jose,

In order to activate the VLAN on your N2K host interface, you will need to implement the same configuration for port Ethernet101/1/48 on the Second N5k /peer (switchport access vlan 41….).

Indeed many configuration and operational parameters must be identical on BOTH Nexus N5k for the consistency (interface 101/1/48 config si one of those). It is very important to have this global consistency between the two N5K peers (confugurations of the VPC – Vpc peer-link – N2K host interfaces….)

This behaviour (vlan suspended for the interface) is the expected one : It is considered as Type 2 inconsistency mismatch to prevent undesired forwarding.         

A recent feature introduced in NXOS 5.0(2)N1(1) called configuration synchronization (config-sync) allows you to configure one switch profile and have the configuration be automatically synchronized to the peer switch.

Best regards.

Thanks Karim

Please recomend me a document to review the conf-syncoption.

Thanks and regards,

Hi José,

The link describing the config-sync feature is the following :  

http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/operations/n5k_config_sync_ops.html

You will find all the details (Guidelines, limitations, details per architectures, configuration example and so on..)

Hope that helps.

Best regards.

Kind regards.
