Personal Notes on Qos on Cisco 2960

November 13, 2020December 25, 2015 by Joost van der Made

I wanted to see what happens when you configure egress Qos with SRR. To accomplish this, I create a policy-map which set the DSCP 40 for WWW traffic.

ip access-list extended ACL_HTTP
 permit tcp any any eq www

class-map match-all CM_HTTP
 match access-group name ACL_HTTP
!
!
policy-map PM_QOS
 class CM_HTTP
 set dscp cs5

interface FastEthernet0/1
 description laptop
 mls qos trust device cisco-phone
 service-policy input PM_QOS

I got a PC and Laptop connected via a Cisco 2960. On the PC I run iperf.exe on the default port and on port 80. On the laptop I have also 2 client iperf running.

Cisco Unified IP Phone Firmware Distribution Methods

Table 1. Summary of Distribution Models

	Peer Firmware Sharing	Load Server	Traditional TFTP
Advantages	• Hierarchy is automatic • One download per phone model on a subnet • Uses TCP • Fails back to TFTP • Speeds up LAN upgrades • Reduces TFTP CPU load during upgrade	• Has same download time as LAN image distribution • Distributes TFTP load over multiple TFTP servers	• Proven distribution • Default behavior
Disadvantages	• Must be enabled on each phone • Hierarchy is formed for each phone model • Hierarchy is limited to subnet	• IP must be set on each phone • Administrator must manually file copy to load server • No failback to TFTP on error • More prone to user error	• High-bandwidth requirements • Multiple requests for same file • High CPU usage on TFTP server
