Known A switch to (24) 20 users share an account on the Internet, is now in A switch to connect A small switch B (12) unknown type has only two users to connect, now switch B problems, according to the Settings should only be connected to the switch B two users can't get to the Internet, but the background shows that connect the two switches of all users can't get to the Internet, realistic reason, how should I change the setting for A switch in B switch failure still can connect to the Internet?

CodePudding user response:

Take out your switch configuration to see

CodePudding user response:

S1526 switch another not clear, only this one is my Settings,

CodePudding user response:

How do you identify the B out of the problem rather than A switch of main lines connected switches or wrong?

CodePudding user response:

Because the problem of connecting two switches connecting cables, connect switch B interface has been drawn, switch B is offline, according to my previous Settings, switch on the switch B offline should be normal to the Internet, but now switch B A single offline, switches can't normal surfing the Internet, A

Thread it doesn't matter, should be the problem of setting, when they put the switch in b should be changed some Settings, now I can't find they changed the part set b

CodePudding user response:

Not the topology configuration, how do you know where we have a problem?

CodePudding user response:

Yes, the simplest is pulled out B swap to see if A normal

CodePudding user response:

Disconnect the connections between AB, restart the switch

Since the hub, the broadcast storm, if they meet their advice on the hub of excuses add loop detection, a loop down automatically

Suggest the local ping, first look for problems
