Egress Shaping on 3750-Gigabit Ethernet Port

Unanswered Question
Oct 16th, 2008

Our customer bought 10 Mbps Metro Ethernet services from the SP on a Gigabit Ethernet port and they are running into issues when they try shaping the Gigabit Ethernet port to 10Mbps.

Has anyone encountered a similar problem ?

Any feedback would be appreciated

Thanks Edison for your response. I looked at these configuration documents. Actually the Customer is seeing a specific problem where on a 1000 Mbps port he is able to shape to say 100/ 500 Mbps but when he tries to shape that port to very low values like -- 10 Mbps etc that he is running into issues.

I was wondering if there is a lower limit on a Gig pot to what value can it be shaped

Normal 3750 ports only support shaping in tiers (multiples of 6?), although the shape command allows 1% increments. I.e. you can't actually obtain the exact percentage you shape for.


If possible, hard code the port for 10 or 100, and then shape.
