As shown in figure, the original SW1 and SW2 G1/0/1 for the Access and Access VLAN200 mouth, to increase the passthrough between SW1 and SW2 VLAN1, opening in SW1 and SW2 will VLAN1 has three layers and matches the IP address, first the SW2 G1/0/1 port from the Access port to the Trunk, so we won't be able to manage a SW2 network PC, then SW1 G1/0/1 port from the Access port to the Trunk port and the port Trunk permit vlan 1, 200, the last test in network management PC SSH192.168.1.2 or management SW2, ping ping also impassability, mouth to mouth Trunk but SW2 G1/0/1 after the default port Trunk permit vlan 1 ah, is this why?

CodePudding user response:

SW2 G1/0/1 modification for the trunk, the default is only allowed through vlan1 data, but your network PC belongs to vlan200, so can't connect to SW2,
You put the network PC's IP is modified to 192.168.1. X, then the G1/.two survivors to vlan1, to connect the SW2 vlan1 IP (192.168.1.2 instead),
Under test first,
