Multiple trunk ports on switch

How many ports on a 2950 can be configured as dot1q trunks? I need to place an intermediary switch in my network to pass trunk data beween 10 other Cisco switches and therefore need to configure 10 ports as trunk ports. Is this possible or would a different switch work better for this purpose?

Hi Scott,

There's no limitation on the number of trunk ports you can configure. However, there is a switch-wide limitation of 64 instances of Spanning Tree. In other words, you can only have 64 active VLANs on the switch.

See:

HTH,

Re: Multiple trunk ports on switch

hello,

I dont see why you could not configure 10 trunk ports in your 2950 switch.

Anyway what is the 2950 you have?

But I would like to know if anyone found a problem like this?
