Hi Jason, Thanks for the explanation. So, I would like to understand another scenario.
Similarly, I have a 384K frame-relay WAN link, so I have: ! map-class frame-relay FRTS-384 frame-relay cir 364800 frame-relay bc 3648 frame-ralay be 0 frame-relay mincir 364800 frame-relay fragment 480 ! Now, for LLQ I want to configure to only prioritized 5 g729 calls: ! policy-map LLQ class media priority x class control bandwidth 16 class class-default fair-queue ! So, the x value is 5 g729 calls. How can I calculate the x value? Based on CCM bandwidth for a g729? x = 5 x 24 Please kindly advice. Thanks. ---------- Forwarded message ---------- From: jason sung <[EMAIL PROTECTED]> Date: Thu, Feb 14, 2008 at 11:26 PM Subject: Re: [OSL | CCIE_Voice] QoS question To: "boonchin .ng" <[EMAIL PROTECTED]> Cc: CCIE Maillist <[email protected]> When you have minCIR configured the LLQ picks 33% of that. If you do not have minCIR configured than the CIR divided by two is used in the calculation. In your example, since you have mincir configured. Priority bandwidth will be 364800 * .33 = about 120K LLQ will allow you to configure 75% of the total bandwidth. if you want to alter this, use the command max-reserved bandwidth xxx -Jason On Thu, Feb 14, 2008 at 5:45 AM, boonchin .ng <[EMAIL PROTECTED]> wrote: > Hi, > > I have a 384K frame-relay link.
