Cisco Switching/Routing :: 4510R-E / Unable To Create A Port-channel And Apply Auto-qos For VOIP
Sep 15, 2011
I have a 4510R-E chassis with SUP7-E running IOS XE version 3.01.01.SG. I am unable to create a port-channel and apply auto-qos for VOIP.If I configure auto-qos on the physical interfaces, I get this message when I try adding them to the port channel:
"The attached policymap is not suitable for member either due to non-queuing actions or due to type of classmap filters."
Auto-qos is not an available command in the port-channel interface configuration, but if I try adding the service policies that were created by auto-qos to the port channel manually, it lets me apply the input policy but on the output policy I get this message:
"A service-policy with queuing actions can be attached in output direction only on physical ports."
With the input policy applied to the port-channel interface, I tried addign the output policy to the physical ports and I got this message:
"A service-policy with non-queuing actions should be attached to the port-channel associated with this physical port."
Is there a way to get the auot-qos policies applied to the port-channel properly?
We have a switch that, when configuring auto qos on and edge port facing video equipment, the upstream port channel drops. I was wondering if no auto qos would have to be configured on the member ports of the port channel prior to enabling auto qos on any other ports.
I am trying to create a port channel between HP servers (4 nic) and two nexus 2k. The server side its a single team with 803.2ad fault taulerence and on the nexus side it have created two port channel (port channel 1 for nexus 2k1 and port channel 2 for nexus 2k2) and made them ACTIVE (channel group mode active)
But when i add a another server on different ports and port channel them the same way as the above server on nexus 2k1 and nexus 2k2, the first server stops pinging. so i have to sht down the first port channel and reopen them - then it works, however it says NO NETWORK ACCESS on the servers (running windows 2008). the only way is to reboot the server i cant be doing this on a production network.
I have a router on which I would like to create a port channel that spans two different Nexus 2248TP switches, and then create a couple subinterfaces on the router's po interface. I've done this successfully on my primary router, but the config doesn't seem to work on the backup router. The primary is running IOS 15, while the backup is running 12.4.25d advanced IP. I do see the trunk come up from the switch side, and my router subinterfaces and po interface show up, however I'm not able to get anywhere from the router. It's not even able to reach other hosts on the same network. As soon as I remove the port channel config and use the physical interface and assign the same address used on the port channel interface, everything works as expected and I have connectivity.

Here is my configuration below , i have upgraded my C-3750 switch IOS from IPbase to IPservices , after upgrading i have tried to apply PBR on my Vlan 4 and failed , when i am tying to apply route-map to Vlan4 the command was taking but i am unable to see the route-map when sh run , i am giving the command as "ip policy route-map TTSL" in my Vlan4 , below is the configuration.
In Vlan2 i have connected one ISP and Vlan4 I have connected one ISP , my local subnets are 192.168.1.x and 192.168.2.x , now i want to route the 192.168.1.x traffic from Vlan2 and 192.168.2.x Traffic from Vlan4 .

We've been configuring our swtichports as follows for our 7945 and 6941 type VoIP Phones, but are having problems witht the 6901.
VLANS Vlan 900 is a VoIP VLAN Vlan 999 is a NULL VLAN and is shut down: interface g0/1 switchport access vlan 999 {VLAN to direct data traffic to the bit bucket becuase a PC shouldn't be connected to this port} switchport mode access switchport voice vlan 900 mls qos trust cos spanning-tree portfast
The 6901 phone doesn't support multiple VLANs, so our configuration above does not work unless vlan 999 is turned on (not good security wise). We got the phones to work also by removing vlan 999 and switchport mode access.
switchport voice vlan 900 mls qos trust cos spanning-tree portfast
solution that provides the discarding of data for the access VLAN, while supporting the VoIP vlan for this phone?
Nexus 5500 support auto negotiation on 1gig sfp port? There is an end device that only support auto negotiation and cannot be manually set speed/duplex.
I have 3750 core/distribution switches with routing enabled in two offices connected with copper link and L3 port channel interfaces. NewOffice#2 has moved about 5 miles farther away from office#1 and I have to deploy new core/distribution switch connect it to old core#2 via F.O and move all access switches with it. Old core will stay in old #2 offices as a bridge between office#1 and new office#2 Office#1core<->copper (Ethernet) <->oldoffice#2core<->f.o. <->new office#2core How I should configure port channels ports on oldoffice#2 core to act as bridge between office#1 core/dist and newoffice#2 core/dist without changing anything else (ip, etc) on whole network
I have 2 Cisco 6509 switches linked together via single Fibre as a trunk.I want to change this to a port channel where I will add another 3 fibre ports to the port channel but what order do I do this to minimise any disruption.
1-Configure PortChannel and add the 3 new ports, this will bring up the Port Channel but what effect will this have on traffic currently going over the single Trunk link? Will spanning tree go mad, how will switches react?
2-Convert existing Trunk link to Portchannel then add in new ports to PortChannel, I guess in doing this there will be a small hit on traffic as it changes to a port channel.
We have 2 6513's that are linked via 2 10 gig interfaces, using an LACP channel.I received an alert this aft stating that the far 6513 was unreachable and the port channel int PO3 had gone down, the 2 10 gig interfaces had also gone down on either side. 5 mins later PO3 had resestablished itself and has been fine since.

We are running nexus 5018 in our DC.What is the difference betwen "channel-group 214 mode active" and " channel-group 216" Any difference?.. because i have problem with this config we are going build a server config?
We have problem with porth channel down.

I have configured a SVI in my 4500 ( Sup 7-E 10GE,,,,,,and,,,,,cat4500e-universalk9.SPA.03.02.00.SG.150-2.SG.bin) switch and it is showing Down Down, because there were no active switch port in the vlan, I added one switch port to this vlan but this port also in the down state, so i added the SWITCH PORT AUTO STATE EXCLUDE command under this port, even after this also the SVI never came up, So i added one systen to the port so both the switch port and the SVI came up...So why SWITCH PORT AUTO STATE EXCLUDE command have no effect in this model of the switch..
I am building a new network and intended on using the min-link feature on my port-channels between a 3750-X series switch and Nexus 4k.
However reading further into this it seems this feature is only supported on higher end models. I cannot find any reference to the min-links feature in the 3750-X configuration guide. Is this an available feature?
The 3750-X model is WS-C3750X-24T-L running IOS 12.2(55)SE3 IP Services
My thoughts is that the is only an LACP supported feature so I may not see the command until I have entered an LACP specific command on the port-channel but unfortunately I do not have a 3750X to verify this on at present.
We have one 3825 router used as voice gateway. For redudancy, we want to connect it to two different switches which has STP and HSRP running. Can I create a port-channel with two Giga interfaces in 3825 and connect to two different switches? Should I configure port channel in switch with only one port in each port-channel? I know server can be connected to different switches with NIC teaming. I just want to mimic that kind of setup. I did one time for port-channel in 3825, but it was connected to a stacked 3750X. So it's different case now.
I am trying to configure port-channel from one switch to two switchs, and only one interface of each switches make part of the port channel.Cisco IOS Software, ME380x Software (ME380x-UNIVERSALK9-M), Version 12.2(52)EY4, RELEASE SOFTWARE (fc1) [code]
I have a pair of 6500's setup with VSS and there is currently only one link between then. However one end of the link is on Po10 and the other end is on Po25. If I move the Po25 over to Po10, will things break? It seems to be working fine now. I'm about to add a second link and I'm concerned about the current configuration. It makes more sense to me to have both ends of the same link on the same port-channel ID. I've seen documentation which states otherwise however.

I am using 3560.IP rouitng is being turned off on this.Curious to know if I will create etherchannel or port channel.I think etherchannel.Correct me if I am wrong.On connecting switches I have vlan10,20,30 to be allowed.I am sure I need to allow these all vlan in 10,20,30 which are on the trunk port on each side switch.Post that will add channel-port lacp and make it in active mode.Is that correct.This way traffic will be load-balanced/aggregated on minimum 2 ports who are the part of this.
Here's what I'm trying to do. We are having new storage servers installed that will be using NFS. I'm being told that they need to have their connections port channeled. Right now, the servers have connections to 2 different 3750s for HA. Is it possible to configure a port channel between these 2 connections?
I have an inquiry about a configuration I deploy in a C2960 switch. I have configured a ether channel with 8 ports, the load balanced method is source mac address. The bundling protocol is LACP.
I have found the ether channel is not balanced as I expect. One of the eight interfaces is congested.
I have a Cisco 6500 series switch with VS-C6509E-S720-10G ,I have two redundant supervisors between two chassis on the LAN with no add-on line cards ?
I need to know if I can use the redundant supervisor 10 Gb uplinks to form a layer-2 Port channel between the two 6500 switches as i do not want to use want to keep the port idle additionally I need more bandwidth between the two switches for my server farm?
I have 2 cisco 6500 in a VSS configuration , All of my Lan access switches are Stack switches and every Stack is connected to the VSS in a Port-channel so basically this is a loop free environment with no blocked ports .As a best practice I left STP in the Background (mstp)which enhanced cisco features to STP should I configure on the Aggregator (6500-VSS) and on the Access switches ?
Because of my topology I dont see the need in configuring most features like Uplink Fast and Backbone Fast but I have configured Loop Guard in addition to UDLD on the 6500 Aggregation Switches (on the port-channels).On the access ports I have configured portfast , bpduguard and guard root (seems a little pointless to configure the two...)
1.should I Leave UDLD on and get rid of LoopGuard and configure Guard root instead ? since LoopGuard cannot be configured with Guard Root.
2.should I configure GuardRoot on access ports if I already have BpduGuard on them ?
3.Is there anything I need to configure on the physicall interface or is everything configured on the port-channel since STP reguards port- channel as a single interface ?
Is it possible to use a 10GE interface on a sup720 and an interface from a 671610GE line card and create a port channel. I haven't found specific documentation on CCO stating you can. I have found the QOS queuing is differnet between the sup and line card.
I need adding a vlan to the trunks bundled in port channel. I know how to add v lans to a port channel with Cisco IOS but with CAT OS.
I have 2 ports bundled to form ether channel in switch which is running CAT OS. There are already few v lans allowed in the trunk of each interface. now I need to add one more v lan.
For Example:- v lan 135 needs to be added in addition to the existing v lans.
clear trunk1/2 1-112,115,117-134,136-4094 set trunk 1/2 on dot1q 113-114,116,135
and similarly on the 2nd interface
so if I add vlan135 to the trunk one after another will it cause any service disruption?
I am having hard time in understanding the hardware port channel resource concept in Nexus 5Ks. Which scenario is considered as a hardware port channel and which is not. According to Cisco documentation, 5548UP switch with layer 3 daughter card only supports 8 hardware port channels, does this mean we can connect only 8 dual homed Fex to those 5Ks.Will a dual homed fex consumes a hardware port channel?
I have two Core 6509E SUP2T configued as VSS and has two 48 ports fiber blades. I have two 3750s, I have two gig on each 3750 port-channle to po1 and connected to both the core, one link to each core.Now, I was asked ot add two more links on each 3750 switch to make it a total of 4 gigs on each 3750s (all 4 gig ports/uplinks will be in used an dtwo links to core one an dtwo links to core 2).when i added two additional links on 3750s and bundled them to po1, I created another port channel on core and bundeled the additional two gigs on each core to accomodate for the two additional links (ports on core switches are not consequtives).
adding these two additional ports makes the 3750 switches flap between managemnet vlan and po1.now, i am not sure if I must have added the two additional links on the core to teh current port-channel or core!? I have created another port-channel on core to accomodate for this currently!?
I am a bit confused by the output of 'show run' and 'show run switch-profile' that pertains to a port-channel interface configured in a switch-profile. My main gaol is to find out how can I add/remove the allowed vlans the port-channel (configured as trunk) carries. The setup is like this. I have 2 N5k in vPC domain and Etherner1/11 on both switches is configured as trunk vPC that connects to a core switch. When I issue ‘show run’ for the port-channel and physical interface I get the following output. [code] From above it seems the switch-profile configuration is missing the 'switchport trunk allowed vlan' in the port-channel interface. If want I to remove vlan 30 from the allowed vlan, should I go under the switch-profile mode and remove vlan 30 from the allowed list even though the switch-profile configuration seems to be missing this.
I configured the interfaces individually at L3 and could ping across each link Example:
4500 Switch 2: 6500 Switch 1 int t5/1 - int g3/17 1 Gig fiber link tore down config tried second set of interface int t6/1 - int g8/17 1 Gig fiber link Ping successful
