vPC Consistency Checks with Cisco NX-OS 5.0(2)N2(1): Graceful Consistency Check
Starting from Cisco NX-OS 5.0(2)N2(1), the Cisco Nexus 5000 Series implements the Graceful Consistency Check
feature (enabled by default). With this feature, in the presence of a Type 1 mismatch, vPC links stay up on the
primary switch. The secondary switch brings down its vPCs until the inconsistency is cleared, as shown in
Figure 16.
Figure 16. vPC Graceful Consistency Check Feature
Cisco NX-OS 5.0(2)N2(1) also implements per-VLAN consistency checks for the case in which spanning tree is
disabled on a specific VLAN. If the user disables spanning tree on a VLAN, this VLAN is suspended on all vPCs on
both the primary and secondary vPC peers. Other VLANs are not affected by this change.
