Frame Relay Traffic Shaping [7:4777]
G'day All, I have recently been trying to tweak some FRTS parameters and playing around with Tc. The Cisco site states that Tc should be 125ms max, and I have found this to be a bit large for the majority of our installations. What I generally use as my defaults are Tc=60ms for normal data sites and Tc=10ms if I am setting up VoIP. What I have come across though is that sometimes the router overrides my setting with its own value for Tc say Tc=30ms. 3600 seires routers seem to be the ones that set Tc=30ms.The Cisco site did mention that a router will sometimes select a more appropriate Tc value, but it doesn't mention what criteria it uses for the override function. Does anybody know what the criteria is for a Cisco router to set its own Tc and override one set in a map-class frame-relay.

QOS for Citrix
G'day All, Currently got a problem with a WAN I support where they are getting time-outs with their Citrix Clients. Citrix Clients are connected via frame-relay edge routers 1700's to an ATM core router 7200VXR NPE-200 with ATM DS3 routing traffic between all sites. Can anybody suggest any QOS solutions to prioritize the Citrix traffic. So far I have reserched the following: Citrix Ports 1494/tcp ica 1494/udp ica (not sure which of these needs more priority) bandwidth ~ 20k per user (although I have heard that it can be a lot higher than this) average packet size 300 bytes delay sensitive I am looking at Priority queueing, but a little concerned about the warnings that it may starve other traffic if the Citrix queue is constantly full. If anyone has any suggestions, or played with this before it would much appreciated. Many Thanks Steve _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Radiator
Chan, You can get it from this site, but it is not free: http://www.open.com.au/radiator/ It is a very good Radius product and easy to modify/customize.

Re: VTP Protocal Cisco 5000 and 3com Superstack II 1100
I was looking into this Cisco/non-Cisco switch issue just recently and was told that the 802.1q standard stipulates only 1 x STP, and yet with Cisco's 802.1q implementation you can have per vlan STP (not quite matching the 802.1q standard). Perhaps someone in the group can clear this issue up for us. Steve "Piatnitchi Cristian" [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Hi Rico Take care ! I had many problems with set up a STP, trunking and 802.1q between Cisco 5000 and Bay Networks. I gave up because finally I used just 1 link between these devices. I was surprised to see that FastEtherChannel on Cisco means trunking on Bays'. This is what somebody from CISCO staff suggested to me. -Original Message- From: Washington Rico [mailto:[EMAIL PROTECTED]] Sent: Wednesday, January 10, 2001 4:56 AM To: [EMAIL PROTECTED] Subject: VTP Protocal Cisco 5000 and 3com Superstack II 1100 Dear all, I wonder if anyone knows if it is possible to trunk a 3com Superstack II 1100 with a Cisco 5000 serious switch. 3com switch is the client and recieving vlan info from Cisco5000?

Re: Bandwidth constraints for VoIP
IOS 12.1.2T has generally been the recommended one, but I believe 12.1.5T is now out. Steve "Priscilla Oppenheimer" [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I think the best IOS version to use for VoIP came up in an earlier thread, so you might want to search the archives or perhaps people can remind us. Cisco made quite a few updates and bug fixes in the QoS for voice about a year ago, but I can't recall the IOS version number. Help anyone?

(Oh my God, Priscilla has given an answer to my question!! this must be my big lucky day!! have taken a print out of the reply and kept it in my personal file, i will show it to my grand child someday!!) One last question though, and that is, if IOS 12.x is good enough to implement VoIP, or do I need to ask for additional features? Pardon for not adding the question in the first place (I am bit sluggish, as you may have noticed, in my thinking process!) Regards Ishtiaque From: Priscilla Oppenheimer [EMAIL PROTECTED] To: "Ishtiaque Mahbub" [EMAIL PROTECTED],[EMAIL PROTECTED] Subject: Re: Bandwidth constraints for VoIP Date: Tue, 09 Jan 2001 15:45:59 -0800 Each CODEC has different capabilities for compressing voice, so you'll have to know which CODEC you want to use first. The compressed voice is then put into an IP frame, so you will need to take into account the bandwidth used by headers of the following sizes: 20-byte IP header 8-byte UDP header 12-byte Real-Time Protocol (RTP) header On point-to-point links those headers can be compressed down to just a few bytes. Even the IP header can be compressed if it's a point to point link and IP addressing isn't needed for forwarding to the next hop. If you use Voice-Activity Detection (which uses no bandwidth during silence) you can further reduce bandwidth requirements. Finally, you need to take into account the data-link header, PPP, Frame Relay, whatever. According to a chart that I picked up at Networkers a couple years ago, here are a few examples: G.729 CODEC on PPP without compressed IP/UDP/RTP and without VAD uses 26.4Kbps. G.729 CODEC on PPP with compressed IP/UDP/RTP and without VAD uses 11.2 Kbps. G.729 CODEC on PPP with compressed IP/UDP/RTP and with VAD uses 5.6 Kbps. G.729 CODEC on Frame Relay without compressed IP/UDP/RTP and without VAD uses 25.6Kbps. G.729 CODEC on Frame Relay with compressed IP/UDP/RTP and without VAD uses 10.4Kbps. G.729 CODEC on Frame Relay with compressed IP/UDP/RTP and with VAD uses 5.2Kbps. I would copy and paste the whole chart but I only have hard copy. You should be able to find such a chart somewhere though. Priscilla At 11:47 AM 1/9/01, Ishtiaque Mahbub wrote: Hello Group! A very happy new year to you all!

Is 64kbps is too steep for 4 simultaneous voice operations? Suggestion, advices welcome.

Re: Radius support in cisco routers
Nezar, We needed to go to IP/Plus on a 1600 to get Radius support. This required more flash than the 4mb we originally purchased.

Is it a software version limitation ? For example do newer = releases support radius ? Or is it a hardware limitation ? If this was = the case which series supports radius ? Thanks for your help.

Re: Voice Over IP
12.0.7T at least, 12.1.2T even better. Steve "Amit Gupta" [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Hi everybody, I need assistance on the VoIP problem I am facing : We are planning to have a VoIP setup on the already existing data link between our local and remote office. Both sites have Cisco 3640 routers configured for it. The router on the local site has IOS 11.3(9)T and the remote router has 12.0(5)T1 on it. Is it necessary for the routers at both ends be running a similar version of IOS for the Voice calls to be successful. What kind of upgrade is required? Secondly the loopback test (hairpinning) was successful for the local site but a similar test at the remote site was unsuccessful. Could that be due to any signalling problems ?
