Computing voice bandwidth is usually required for scenarios where you provision LLQ queue based on the number of calls and VoIP codec used. You need to account for codec rate, Layer 3 overhead (IP, RTP and UDP headers) and Layer 2 overhead (Frame-Relay, Ethernet, HDLC etc. headers). Accounting for Layer 2 overhead is important, since the LLQ policer takes this overhead in account when enforcing maximum rate.... [Read the rest of this entry -->]
People are often confused with per-VLAN classification, policing and marking features in the Catalyst 3550 and 3560 models. The biggest problem is lack of comprehensive examples in the Documentation CD. Let’s quickly review and compare traffic policing features available on both platforms. The material below is a condensed excerpt of several Catalyst QoS topics covered in the “QoS” section of our IEWB VOL1 V5. You will find more in-depth explanations and large number of simulation-based verifications in the upcoming section of the workbook.... [Read the rest of this entry -->]
