Hi Jon Many thanks I'm using vlan based QOS because later I'll add more vlans to the configuration, this is just initially to see how to use the QOS function on the 6500 - later we'll use this with more vlans. Essentially the port that is currently gi1/1 may later be a truck port with 10+ vlan's bound to it (with associated vlan interfaces on the 6500). Data arriving from the Server to the 6500 most likely won't have any or valid dscp markings, allvoip is currently simplified just for icmp traffic for testing - so it's looking like this: class-map match-all allvoip match access-group 100 access-list 100 permit icmp any any What is just concerning me is that when I have a continuous ping running I'm getting deltas in the ping times when I have other data downloading off gi1/1 (which makes me think the strict priority queue isn't quite right). -- If I can ask, if I wanted to rate limit the data on vlan6 (say limit the data to 10Mbit) and still also do marking in dscp to enable allocation to the differnet egress queues do you have any suggestions? I can use a police statement classes on the policy-map but I don't really want to police each class seperately kind of like vlan 6 entire capacity policed to 10mbit then inside that allvoip marked EF (and then assigned COS 5 and 1P) etc etc cheers Mark

Hi Jon Many thanks for that reply. I agree the inability to see the counters ticking over on each queue on the ports is a bit of a frustration. Based on what you've said I'm going to have a play further with it and see. However can I ask one more question regards this (for now atleast) - if I place ICMP Into that allvoip class then would you expect the 1p strict priority queue to keep that data perfectly "clean" - from my reading any data in the priority queue would be processed before any data in the remaining queues (which are then wrr). cheers Mark

Hi Jon I meant to ask this as part of my post. Is there any method to actually see the counters on the queues on the egree on the 6500 line cards, show queueing int gix/y shows the queueing configuration but it doesn't show any active counters on the 1p3q8t etc. So as data traverses the port I can't see a way to interogate the switch to get that information. regards Mark

Hi Jon Sorry it may be my drawing of it . Source is server 10.0.3.2 sending data to clientpc 10.0.2.10 the clientpc has a gateway of 10.0.2.149 (vlan 6 interface IP on the 6500). I think all is wired right however the egress queueing doesn't seem to be right. does my configuration look like we've missed something with the QOS? cheers MArk

hi Jon Another vlan another port (sorry should have added that configuration to my original post) (10.0.3.0/24 network) connected to vlan 2 on gi1/2. so testpc (10.0.2.10) <-> cisco 6500 on port gi1/1 (vlan6) <-> port gi1/2 (vlan2) <-> Server (10.0.3.2) As data comes from the server to the testpc the allvoip class is being used and the packets are definately marked EF by the 6500, however when I "aggitate" the link between teh testpc and cisco 6500 the allvoip traffic gets impacted. Am I right to assume if the traffic is being assigned the way it should DSCP=EF -> COS 5 and COS 5 associated with the 1p queue on the egress of the 6748 line card) then that traffic should always "go first" and get the strict priority that the queue should provide? ! interface GigabitEthernet1/2 description Uplink to Core switchport switchport trunk encapsulation dot1q switchport trunk allowed vlan 2,99 switchport mode trunk mls qos vlan-based mls qos trust dscp interface Vlan2 ip address 10.0.3.1 255.255.255.0 mpls ip Kind regards Mark

hi all We have a test setup in our lab that we are working with and we believe we must be missing something. The kit is a 6500, Sup 720B, WS-X6748-48-GE-TX line cards. We are attempting to implement PFC QOS to ensure uninterupted throughput of real time data (dscp=EF). Our basic configuration mls qos map cos-dscp 0 8 16 24 32 46 48 56 m ls qos policy-map QosVoice class allvoip set ip dscp ef class class-default set ip dscp af21 interface GigabitEthernet1/1 switchport switchport access vlan 6 switchport mode access mls qos vlan-based mls qos trust dscp interface Vlan6 ip address 10.0.2.149 255.255.255.0 service-policy input QosVoice In our setup we are passing data from a far end interface into the 6500 and through to vlan internface 6 (and out port gi1/1). If what I believe is correct then data coming to the switch from vlan6 and out via gi1/1 will pass through QosVoice (and I confirm using wireshark that this is happening), the allvoip class is marking dscp=ef (from the packet capture). My concern though is that this data is not being placed into the strict priority egress queue on the 6748 line card. "show queueing interface gi1/1" suggests it is (see end of post). However when I do some "real world" testing I truely don't believe that traffic in class "allvoip" is really getting strict priority how I would expect. I for example temporarily placed icmp data into this class and when doing large downloads the ping times would be impacted (changing from <1ms to between 3 and 6 ms) - with a strict queue I woudl expect those ping packets to stay totally stable independant of traffic in other queues. Can I get any input or feedback on our setup? regards Mark Interface GigabitEthernet1/1 queueing strategy: Weighted Round-Robin Port QoS is enabled Trust boundary disabled Trust state: trust DSCP Extend trust state: not trusted [COS = 0] Default COS is 0 Queueing Mode In Tx direction: mode-cos Transmit queues [type = 1p3q8t]: Queue Id Scheduling Num of thresholds ----------------------------------------- 01 WRR 08 02 WRR 08 03 WRR 08 04 Priority 01 queue thresh cos-map --------------------------------------- 1 1 0 1 2 1 1 3 1 4 1 5 1 6 1 7 1 8 2 1 2 2 2 3 4 2 3 2 4 2 5 2 6 2 7 2 8 3 1 6 7 3 2 3 3 3 4 3 5 3 6 3 7 3 8 4 1 5

Almost wish we had more 508's and not 504's for some extra buttons. - Are you across at all if the SPA phones can be pushed a notice via a SIP message. We'd be happy using PSK toggles if we could push a status notice down to the phone from the switch - atleast the state could be asserted back to the phone visually "DND and CFWD Active" for example.? It's a little frustrating, the SPA series is so close to being exceptional and just falls 1% short. I'd be curious if anyone uses the Annc services on these phones, given that they are 1 way and possibly prone to failure and yet they've invested so much into their firmware for all that guff and then dropped the ball on some simple stuff that would really be useful!

Hi Dan I'm curious what you did for the bi-directional signalisation system? We were considering using a line key with blf+sd to illuminate and toggle. Then remove the dnd softkey. Atleast then it can be set on phone or on server (and pushed back to the phone to ensure 100% synchronisation). The only problem we have is that uses a line key which I'm not really happy about. I wish you could use a BLF in combination with a PSK then it would be perfect (to toggle between psk ext1/nme1 and ext2/nme2 (Cisco hint!) Like all this stuff nothing is perfect, it's somewhat a compromise. We've got the same issue with regards cfwdall, we'd like to have cfwd set at the server (so it can be controlled from phone or from our portal applications), but clients tend to like the the softkey approach, again if the phone loses it's connection or is powered down all bets are off. Keen for any feedback you may be able to add! cheers and thanks! Mark

Hi Guys I think I answered this elsewhere: Hi All One way to achieve this works fine (I think): 1) In Regional Tab note down the DND Act Code and DND Deact Code (ie *09 for act and *10 for deact) 2) In Regional Tab Enter the Virtacal Service Announcement Code section * Service Annc Base Number as the prefix to dial (on your PBX) * In Service Annc Extension Code add DDT:x;DDT:y where x and y are the suffixes appended to the prefix you dial to enable and disable DND on the server, IE use something like 9998 for the prefix and 1 and 2 for the suffix, so 99981 enables DND and 99982 disables DND. 3) Now for some reason Cisco don't send these codes when you press the generic dnd/-dnd Softkeys so you need to remove these and program your own to replace them. Luckily as of firmwere 7.5.3 cisco support dual states on psk's so you can have a + and - version of the same key: 4) Phone tab. Programable softkeys enable = yes PSK 1: fnc=sd;ext=*09;nme=DND;ext2=*10; nme2=-DND (note the *09 and *10 are from the regional tab on the DND Act and DND Deact code) Under the Idle key list find the dnd|8 and replace it with psk1|8 to get rid of the generic internal dnd softkey. save and reboot. Now you still have DND on your idle soft keys, press it, your phone should both set DND, change the soft key to "-DND" and add "Do Not Disturb" across the screen panel. Most importantly the phone will now auto dial 99981@$proxy and the switch now knows the DND state. Press the -DND softkey and the phone will disable DND locally and also dial the switch telling it dnd is now off. I'm 99% this is what people have been asking for? Essentially local dnd support with server notification not having to dial the crazy *codes to make it all work? Cheers Mark
