Cisco WAN :: 2911 - Configuring Priority Queuing In Gigabit Interface
Jun 10, 2011
I have configured Priority Queueing in my Cisco 2911 Router. I have set queue list high, medium, normal and Low. But when I put show interface gi0/2, it is showing the queueing strategy is priority queueing but it is not showing the (size/max/drops) values.
I need to get some low volume, interactive data, prioritized on frame relay PVCs across our network. I have followed the CBWFQ examples from cisco.com, but my test packets are still showing latency over 1 second. My lab set up has a corporate connected gateway router linked via FE to testrouter 50. TR51 has a T1 frame relay loop to another router acting as a frame relay switch. The other side of the FR switch has a 56k link to testrouter51. I am sourcing test pings from my desktop PC, that are marked as AF43, and leave at a rate of 1/second, when the response comes back in time. I am using a Smartbits to generate some default class traffic at a rate of about 56Kbps only in the 'outbound' direction, toward TR51, as this emulates a file copy from corporate to remote sites, that is causing the AF43 traffic to suffer. Here is the relevant config on the TR50 device:
class-map match-all rtu-data match ip dscp af43 ! policy-map frame-56 class rtu-data priority percent 20 class network-mgt-data bandwidth percent 5(code)
I have an Ethernet Loopback Plug (4 Pairs) made and trying to test the Gigabit Interface on a 3845 Router with a fail result. The interface will show up/up only if I set the interface to 100M/Full Duplex when I plug-in the Ethernet Loopback Plug (4 Pairs). I don't see this Gigabit Interface @ 3845 router has any option to set it to internal or external loopback.
i have a 3560 connecting to a sp with limited bandwidth. i have one interface on the switch whose traffic i do not want to drop. i want this traffic to go into the high priority queue. i am not sure how this should be configured, but here is my best guess and my current qos configuration on the switch:
I am trying to configure Crypto PKI in ciscio 2911, Once i configured the root certificate for the router , i can see the validity date wrongly but the same certificate is fine in the other devices . [code]e when i am trying to configure the local certificate.
I had purchased a HWIC-8A in an effort to provide terminal server capabilities into multiple routers. I had found a document that I thought would take me through the configuration but it doesn't appear that the command syntax is the same on the 2911's as it is in the document. Does any know how I would need to get this configured on the 2911 router?
I have 1x Cisco 6509 with Sup2 and MSFC2 and it is running on IOS (c6k222-jk9sv-mz.122-17d.SXB11). I have following policy map :
Policy Map VOIP Class IP PHONE priority percent 75
and the following command on each interface: service-policy output VOIP those configuration are working fine on SUP2 with MSFC2 but last week I tried to upgrade the SUP2 to SUP32 on the switch and upgrade the IOS to the latest version (s3223-adventerprisek9-mz.122-33.SXJ4) but when I try to put service-policy output VOIP on each physical interface I am getting the following error:
"Priority command is not supported in output direction for this interface" and when I try to add service-policy output VOIP on a V LAN interface I am getting following error:
MQC features are not supported in output direction for this interface. Will I need to change something after upgrading to SUP32..
I am trying to configure a shdsl port on a 2911 router for CO mode of operation.The dsl-group auto command does not seem to change the port to operate in CO mode and the link will not come up to a remote router that has a card installed operating in CPE mode.The configuration I have applied for the shdsl controller is.
controller SHDSL 0/1/0 dsl-group auto ! !
Do I need to use a HWIC-4SHDSL card for the CO mode operation?
I have a 2911 router where I was configuring the device to allow remote desktops connections. Everything is working properly, but for some reason my ACL has disappeared.
I am using a Cisco ME 3800 switch with 24 Gig and 2 Tengigabit interface. But after configuring the Tengig int with ip add and negotiation it is no know visible in the switch. Instead TenGig I am seeing two (Gi0/1 and G0/2). Not even showing the Tengig in the running config.
I've got Cisco 7609 with WS-X6708-10GE (8x10Ge)And one port (te9/4) from it have zero bit rate counters, but all the rest of it are very good.I can see traffic if read it by SNMP. [code]
We have a number of 3845 routers, some running IOS 12.4(22)T2 and earlier and some running 12.4(24)T4. On the ones with 12.4(22)T2 and earlier, gigabit interface g0/1 shows interface down/line protocol down when there is no cable connected to the interface and the interface is not in shutdown state. On the ones with 12.4(24)T4, gigabit interface g0/1 shows interface up/line protocol down when there is no cable connected to the interface and the interface is not in shutdown state. Interestingly in both cases, the "show controller g0/1" command shows " network link is down (NO CARRIER)" when there is no cable attached. It makes sense to us that the interface status would be down/down when there is no cable attached. It does not makes sense to us that the interace would be up/down. Did Cisco at some point change their philosophy on whether an interface should show down/down or up/down when there is no cable attached, or is this a bug?
i'd like to force the speed/duplex of the integrated Gigabit interface on a LAP1042N, managed by a 4402 running software version 7.0.98 but I cannot find the command either by command line or on the GUI.
I want to connect 2 ISP links into one Gigabit-interface on my Router 2921, can any one tell me how to do that ? sub-interface creation is not possible on cisco 2921
I need a interface v.35 on 2911 router, but it does not have WIC slot, it has EHWIC. Could some one told me if there are a card with V.35 interface that I can install in this model of router?
I have a question about speed negotiation process between interfaces. I have 3650X Sw and 2960S-48port. All ports of two are GigabitEthernet, however the link between them is only 100Mb/s, Full duplex. I try to set the speed 1000 Mb/s manually in the interface then the interface never up. Its status is down/down. I must set back to speed auto. I show interface Gigabit0/24 in Sw 3650-X and figure out that there are many output drop (over 600000). I clear counter then after two days the output drop is over 70000. This link is trunk link between two switches, all ports of access SW are Gigabit and connect to PC. First, I thinks the 3650X is throttled somewhere in output direction of trunk link. But there is another trunk link (Gi0/23) to another 2960S-48port and no output drop number in this interface. This Giga 0/23 speed is 1000 Mb/s (auto speed, auto duplex)
Does any outside things impact the speed negotiation process between 2 interfaces? And output drop number may caused by abnormal speed between two Gigabit interface?
We bought a cisoc 2911 Router with an EHWIC-VA-DSL-A Card. I did the Dialer Setup without any problem but if i set the ATM interface with the commands: [code]The Router crashes after some seconds. I didn't connceted the phone line to the DSL card. [code]
having some issues with a configuration using a Dialer interface. The interface comes up and the VPN tunnel comes up, but cannot access any network resources or the Internet.
The things that concern me most are my access lists as I have the static IP address that we are assigned via PPPOE - the IP never changes, but not sure if I can define it in the ACL or if I should be using an ANY tag.
Note: I've changed some IPs and username for security reasons.
During WAN troubleshooting, I did a "clear interface ser0/0/0" on a branch router. It has two WAN links. I lost ssh/telnet connectivity but both WAN links were still replying to pings. We did a manual power off of the router to regain connectivity.Is there a known issue with this command on this IOS version? We're using Cisco 2911 platform with IOS 15.1-1.T2 version.
have been tasked with completing a Cisco config update on an ISR.Client is running a Cisco 2911 running IOS version is 15.0(1)M6.They have added a new WAN interface to GigabitEthernet0/2 and are looking to setup a basic failover configuration to augment their current 0/0 Fiber connection.
We have a 2911 Router running 15.0(1)M4. G 0/0 is our LAN interface, and it has three subinterfacesG0/0.1 is our data LAN, and the gateway for our Windows machines. This is the interface this question concerns.G0/0.23 is a separate LAN for various equipmentG0/0.192 is another LAN for equipmentG 0/1 is connected to the internet, and has a public address.S 0/0/0 is a T1 PPP, connected to our core data centerS 0/1/0 is a backup T1 PPP, again, connected to our core data center.There are three static routes entered:ip route 0.0.0.0 0.0.0.0 10.12.1.1 100 This is the first PPPip route 0.0.0.0 0.0.0.0 10.13.1.1 200 This is the secondary PPPip route 0.0.0.0 0.0.0.0 xxx.xxx.xxx.xxx 255 It currently has a cost of 255 while i figure this one out. xxx.xxx.xxx.xxx represents the cable company gateway, which I can ping properly. I've also used "gigabitethernet 0/1" in place of the next hop ip with the same results. The public interface is properly connected, and can ping it's next hop (the cable company gateway). When I change the static route for gigabitethernet 0/1 to a cost of "0", the router can properly ping DNS names, such as google.com through the public interface.
However, devices on the data LAN cannot reach any public addresses except for the router's public interface, let alone DNS names (I am using 8.8.8.8 as my test IP). If I revert the cost back to 255, making the PPP the gateway of last resort, these devices can again connect. (they travel through the PPP to our Data center's internet)
This confuses me. If our server, on the same LAN as the router can ping the public interface (it's definitley not leaving the 2911, as latency is less than 1ms), and the router itself can ping outside addresses, what is preventing the router's public interface from passing traffic to the internet from any source other than itself? I have attached our running config in the hopes that there is something obvious I'm missing (the public ip addresses have been changed so they are not exposed). I simply want clients on our 10.23.0.0 LAN to get to the internet via the public interface of the local router, and still connect to corporate resources using the PPP links. MAS_2911#sho run

I have a 2911 router connected to two different ISP. Is it posible to route traffic based on what interface the traffic came first?Lets say I have the deault route to use interface gig0/0(ISP1), but a certain ip packet reach the router by interface gig0/1(ISP2). Is there any way (if possible without using source NAT) that I could route traffic back to that ip address using interface gig0/1. The source Ip addresses are not fixed, so I can not use Policy Based Routing.
I need to configure a Cisco 2911. I need to give an interface in this module (VWIC3 - 4MFT-T1/E1) an IP address. My question is, how to assign an IP to an interface in this module.
My purpose is to get connectivity via T1 line to another router.
I am trying to configure a loop back interface like so: [URL], on the following device:
C3550 Software (C3550-IPSERVICESK9-M), Version 12.2(50)SE, RELEASE SOFTWARE (fc1on port gig0/1 which is using a 1000Base-SX adapter. This is for troubleshooting purposes and it does not appear to be a feasible option. Is there another way to accomplish in the IOS?
I have a Cisco 2911 router and a Cisco RV 120W router and i would like to establish a VPN tunnel between theese two. I have defined the settings on the Cisco RV 120W router and i just want the Cisco 2911 to follow those. setting up a connection with Cisco IOS.
I have configured multicast (ip pim dense-mode) on two 2911 routers that are connected by a Multilink (3Mbps) Wan connection.The configuration work fine for awhile and sometimes all day but at some point one of the Multilink interfaces stop passing multicast traffic.I perform a sh multilink 1 on the interfaces and one interfaces show the multicast packets incrementing and the other does not, it just stops.The only fix for this is to hard reboot both routers and the multicast traffic begins to flow once again.
I have been having following situation on my WAN facing interface on Cisco2911 where the same number of broadcast, multicast and unknown protocol drops is happening. Not sure but some applications are struggling to run over on the WAN.
