Configuration Parameters That Should Be Identical; Viewing Type-1 Inconsistency Check - Cisco Nexus 3548 Configuration Manual

Configuration Parameters That Should Be Identical

Configuration Parameters That Should Be Identical
When any of the following parameters are not configured identically on both vPC peer switches, a
misconfiguration might cause undesirable behavior in the traffic flow:
• MAC aging timers
• Static MAC entries
• VLAN interface—Each switch on the end of the vPC peer link must have a VLAN interface configured
• All ACL configurations and parameters
• Quality of service (QoS) configuration and parameters—Local parameters; global parameters must be
• STP interface settings:
To ensure that all the configuration parameters are compatible, we recommend that you display the
configurations for each vPC peer switch once you configure the vPC.

Viewing Type-1 Inconsistency Check

After you have configured the Virtual Port Channels (vPC) peer link on both vPC peer switches, check that
the configurations are consistent on all vPC interfaces. Cisco NX-OS Release 9.x supports vPC in warp mode.
Note You must ensure that both the vPC peers are in the same forwarding mode. In case of a forwarding mode
mismatch, vPCs are suspended.
This example shows how to check that the required configurations are compatible across all the vPC interfaces:

for the same VLAN on both ends and they must be in the same administrative and operational mode.
Those VLANs configured on only one switch of the peer link do not pass traffic using the vPC or peer
link. You must create all VLANs on both the primary and secondary vPC switches, or the VLAN will
be suspended.
