How to force "re-link" of all ports

Well, simulating manually without physically unplugging the cables:

Switch>enable
Switch#configure
Switch (Config)#interface 0/xx
Switch (Interface 0/xx)#shut
Switch (Interface 0/xx)#no shut
Switch (Interface 0/xx)#exit
 

ahah, I never thought of this one.

i'm sure it will work, i'll use this if I have to switch to redundancy while i'm at the office, but i've forget to ask something in my previous post.

this should be an automatic process, like "resync" every 10 minutes or less.

thanks

Hi thanks for your answer, I never thought of this one...

but I forget to add something in my previous post. This should be an automatical process. Like "resync" every 10 minutes.

Yup, that's why I set "manually" in bold, because I expected you were looking for something more automatically. :)

Would be interesting to see if killing the ARP table manually would also do the same as shutdown using

clear arp-switch

- or possibly the

clear arp-cache

commands.

You might also be interested in the

show arp

and

show arp-switch

commands.

Confirmed, the shut/no shut is working
the clear arp-switch and clear-arp cache do nothing to the unicast

here's th show arp result, but I dont see here any of the unicast feed, only the computers managing the switch.

i've forget to tell taht aI have Vlan1 for management in 192.168.1.0/24 and vlan102 for TV equipment in 10.0.0.0

maybe another clear "something" command will do the job.
