Redundant trunk ports

bramlermitte

Hi

I am new to Cisco. I am an audio engineer. I am trying to get 2 trunk ports in the same switch. So when one cable fails, the other port automatically takes over the trunk duties. I have two switches. the 2 cables would go to the same switch. 

 

How would I go about doing it? Maybe in the GUI?

You can do this

interface gigabitethernetX
channel-group 1 mode on

interface gigabitethernetY
channel-group 1 mode on


interface Port-channel1
description  "You channel name"
speed 1000
no negotiation
switchport mode trunk

Do it in both switches.  Then you are going to have a trunk between them with physical redundancy and 2gigabps capacity.

Hi

Would be interesting to know which switch model is it.

But, instead two interface in trunk, if you are seeking for physical redundancy, put those 2 interfaces in Channel. This way if one port fails the other will take over and you dont need to configure it independently and nor be waiting Spanning tree protocol to converge.

  Just tell which switch is it and we can provide further help.

HI 

Thanks for your reply. 

 

Its a Cisco SG300 switch, it's a fairly old model.

You can do this

interface gigabitethernetX
channel-group 1 mode on

interface gigabitethernetY
channel-group 1 mode on


interface Port-channel1
