Slow dhcp with ESW 520

Hi ,

it's probably a setting to do on ESW 520 but all my DHCP is slow when I use ESW 520.

With an other switch, I haev no problem.

Any Idea?

Thanks

Wrong forum, post in "small business - switches". You can move your post using the actions panel on the right.

Hi Thibaud, 2 things to ensure. First, make sure you have defined the port role using the smart port wizard.Second, ensure the spanning tree port fast negotiated.

Hi Thomas,

I have already define the Profile type (Desktop, Switch,...) with the VLAN for all the port.

But before make something wrong with the spanning tree configuration, I have one question, I learn that port fast negotiation shouln't be use with Switch Port Role but Only with Desktop Port Role. Can you say me if it's right?

Thanks for your answer.

Thibaud, that is correct. Portfast should not be applied to device roles - such as switch, router, etc.
