Fibre link between switches

[Stormborn15]

Hi ,

Still trying to figure out inherited network...

So, one of the switches is linked to another cab via a fibre link.

My question is ...

can a fibre link port be a trunk port?

The fibre is currently down, and is being replaced soon. Meantime no voice vlan traffic is going through ..so is the fibre link acting as trunk?

Sorry if this is a silly question....

TIA

Any port can be a trunk port, you just change the link type in the config.

The above is correct.

 

A fibre port is nearly identical to a copper port.

 

I would say the vast majority of fibre ports are trunk ports.

Like you I inherited a rather interestingly? built network.

 

Fibre linked two switches accross adjacent buildings. Fibre to Ethernet convertors at each end.

 

Turned out one of the fibre to ethernet convertors was faulty, completly killing the connection.

Yep - fibre modules are prone to failure - especially the genuine badged high price ones. Buy a cheap Chinese one for £10 and it will last for ever (or seems to - for our netgear switches).

Currently my experience too. 4yr old Genuine Cisco ones have been replaced under warranty twice, FS.com generics in a Zyxel Switch, carrying on, carryin' on for the same amount of time.

Sure, just need to change the corresponding configuration.

It’s the port of the switch that is configured, so any port of a switch that supports the capability of VLAN traffic can be a trunk port.

If you switch supports it you can also configure a LAG to bind 2 or more ports together so the the link is made up of more than 1 physical connection, the main advantage is that if 1 link fails the other link will take over without downtime plus when all are working you have higher bandwidth across that link.
