Home Lab!

Well today I decided to get back into the lab at home and tidy up on some core UC skills and tasks. This is what I have achieved this weekend…

  • ESXi build
  • Layer 3 switch configuration to create networks for HQ Voice Servers + Voice VLAN/ESX Mgmt and also added my home PC to the switch so I can see all networks..
  • CUCM 10.5 Publisher build
  • Windows DNS Server (Lab.local forward look up zone)
  • 2 IP Phones registered (1 SCCP and 1 SIP)
  • RTMT for CUCM installed
  • Traces enabled
  • Played with CUCM traces and Translator X (Way cool!)
  • Real time traces with RTMT
  • CUC 10.5 Single Node Build
  • Integration with CUCM (Both SIP + SCCP methods)
  • MWI + Voicemail working (Had some issues with this and turned out just to be an issue with MWI not being enabled on the extension!! Doh!)

Note to self – This is the 1st time I have ever installed CUC. Was pretty much the same as CUCM…

One thing that I always notice in home labs…. installing CUCM and CUC is not a quick process. Also the time it takes for Tomcat to fully kick in is painful!

QoS Practice Lab – LLQ

Ok so I have started some of the practice questions for me QoS exam at the end of Feb. I came across a good lab style question which I decided to answer using Cisco Packet Tracer.

Here is the requirement:

LLQ_LAB

I set this  up in Packet Tracer itself and here is my config on R1:

class-map match-all BULK
class-map match-all INTERACTIVE
class-map match-all VOICE
!
policy-map LLQ-POLICY
 class INTERACTIVE
 bandwidth 30
 class BULK
 bandwidth 16
 shape average 24000
 class VOICE
 priority 168
 class class-default
 fair-queue 
interface Serial0/0
 bandwidth 10000000
 ip address 10.1.1.5 255.255.255.252
 service-policy output LLQ-POLICY

Which I believe is correct for the requirement. One of the key points was the question specifies a ‘strict priority queue’ for voice. Therefore you must use the priority command in the policy to enable LLQ. Everything else was fairly straight forward.

Verify:
