I have two sets of 3560 to do HSRP, the following connected more than 10 2950 or 2960 (each with two lines, one will be blocked by the spanning Tree Protocol), 3560 is zoned 3 VLAN1, 2, 3, the following 29 is not zoned VLAN, The interface between the two ends of the switch is set to access mode, and now the problem is that 29 of the 3560vlan1 are not reported, and 29 of VLAN2 and 3 are reporting similar%cdp-4-native_vlan_mismatch:native VLANs. Mismatch discovered on GIGABITETHERNET0/19 (2), with sw-m1402 GIGABITETHERNET0/23 (1). Such errors do not affect normal use. Supposedly both ports are designated as access mode should not be reported to the native VLAN mismatch wrong ah, do not have to manually change the port belongs to the Eigen VLAN? Ask in ...



You recall the concept of the native VLAN. What is a native VLAN? The native VLAN is a VLAN without tags. Do you recall that frame with the port configured for access has tag? No.. So switch port access is native VLAN 100. So you can understand why access port also reported native VLAN mismatch wrong?
