Hi Yes you have to add the command ip rsvp bandwidth 140 for example into the frame relay interface pointed to the branch that you will enable the cac and vice versa also are some extra config into the cucm for location cac Regards Chrysostomos From: ccie_voice-boun...@onlinestudylist.com [mailto:ccie_voice-boun...@onlinestudylist.com] On Behalf Of ie ravindra Sent: Τετάρτη, 30 Ιανουαρίου 2013 12:12 μμ To: CCIE Study Subject: [OSL | CCIE_Voice] [OSL | CCIE_VOICE] Location Based Call Admission Control Hi All, Do we need to enable ip rsvp bandwidth command when we configure location based CAC.

Re: [OSL | CCIE_Voice] [OSL | CCIE_VOICE] Location Based Call Admission Control
The two types of CAC are locations-based and RSVP-based. On CUCM they both have a configuration set on the location page, which may seem confusing at first. The key words to watch for in the scenario will be once bw is exceeded reroute call over PSTN means you need AAR, which could be either locations or RSVP. It they explicitly say use RSVP or if they say once bw is exceeded the call should proceed over WAN but get remarked down to [given DSCP] then this means you need to use RSVP. * * *When using RSVP, do not put a bandwidth on the location page in CUCM!* *Locations-based CAC setup:* -configure the location page with the bandwidth for the requested number of calls (24*Number of calls, do not add 16K for call setup) -that's it! CUCM will keep track of how many calls are going in/out of each location *RSVP-based CAC setup:* -first, you still go to the location page in CUCM, but DO NOT PUT A BANDWIDTH on the location -in the lower section of the locations page, select another location, use the reservation drop down box: - mandatory (video required) - not relevant for the lab, CUCM will try to setup audio and video and call will fail if not enough bw (then AAR will kick in if configured) - this *should* work the same as the next option since we're not using video phones, but I would suggest using the next option instead - mandatory (video desired) - use this option if you want out-of-bandwidth to reroute over PSTN (using AAR) - optional - use this option if you want the call to get remarked to a best-effort or CS1 and still go over the WAN - no reservation - this means RSVP is disabled -once the location is setup to use RSVP, you need to create an MTP for both sides of the RSVP call. For example, if using Site A to Site C, create an MTP for site A, add to MRG/MRGL and assign to site A phones, then create an MTP for Site C add to MRG/MRGL and assign to site C phones -now on to the routers, you will need to create an MTP on each router. go to the documentation site CUCM config examples and text notes ctrl+F to search for MTP and grab the IOS CLI from here. modify the sample CLI in notepad and make sure to add the rsvp command under the dspfarm profile # mtp. -finally, go to the serial sub-interface and assign the command ip rsvp bandwidth X. On this line the bw is 24*Number of calls + 16 (call setup for a single call -make sure the IOS MTP is registered in CUCM -when placing a call, use show ip rsvp reservation to watch the RSVP in progress. while ringing the output will show 40k, once connected it will show 24K.

Re: [OSL | CCIE_Voice] [OSL | CCIE_VOICE] Location Based Call Admission Control
One more comment on CAC, but for the real world not for the lab... Locations CAC is quick and easy to setup, you don't touch the routers at all. The downside is it is really designed for a hub and spoke topology and it does not account for multiple circuits. RSVP on the other hand is path-aware, meaning you can have redundant circuits with different bandwidths. If you have a primary WAN with an rsvp bandwidth 1000 and a backup link (cable, DSL, etc) with an rsvp bandwidth 100 then the specific routers in the path of the call setup will be used to either admit the call or reroute via AAR. During normal conditions you can admit a lot of calls, but during failover where only backup circuit is active you can only admit a few calls.
