I have a vlan that is used for ip cameras. This vlan is routed with other vlans on our Cat 4506-E. how can i implement multicast feature to improve performance?
View 1 RepliesI am configuring multicast in a environment where I have a 4506 at each site (4 total) and a 6506 as the core. Each 4506 is connected via layer 3 to the 6506. I have a mix of 3560s, 3548s, and 2960s connected to the 4506s and the 6506 via layer 2 trunk
I have multiple multicast sources and hosts communicating at a time (multiple cameras sending video / multiple computers receiving video). So this is not a scenario where there is 1 sender and many receivers. This would be many senders (~50) and some receivers (~10)

I configured ip multicast-routing on each of the 4506s and on the 6506. IGMP snooping is on by default on the 3560 and 2960 switches. CGMP is on by default on the 3548 switches.
I set up PIM sparse-dense mode and IGMP version 3 on each of the layer 3 interfaces for the 4506s and 6506 where they connect and on each VLAN that is sending or receiving multicast. Multicast is working throughout the network, however I am looking to verify the configuration as I scale this out to more clients on the network.
#1 - Is it correct to us sparse-dense mode in this configuration?
#2 - Do I need to configure a rendezvous points using AUTO-RP? (ip pim send-rp-announce INTERFACE scope TTL). Not sure here if I need to designate this and what to choose. Right now I do not have this and it is working, but documentation seems to infer that I need to designate this.
#3 - Is there any other configuration settings I should be considering? I hard to find real world configurations of multicast as examples or people that know multicast routing well.
I have a cisco851 and is currently configured this way.
1 .- This well configured?
2 .- the internet encourages me a little as I can improve
3. - how I can improve the performance
You are responsible for managing and configuring printers and print servers for your organization. You must determine what you can do to increase the performance of your print servers responding to client print requests. What options are likely to improve print server performance?
View 4 Replies View RelatedI read the sticky related to firmware updates. I have a DIR-655, that has been been giving me good service for quite a few years. I subscribe to the "if it ain't broke, don't fix it" philosophy as I have managed to keep my home network and computers running over the years, but I'm not knowledgable in these matters. I am still running firmware 1.10, and have not wanted to take a chance that if I upgraded I would find myself with numerous devices with no connectivity (running mix of Mac and PC desktops and laptops, XBox, Wii, Roku box, numerous iPhones and iPods, LG TV, and an iPad).
Recently I moved to the cable company phone, and they added a new modem. They have it set as a gateway (I think that is the terminology), and my network works basically as it did before. I have noticed though, that my Roku box, laptops, and skype on my Mac desktop seem to be having periods of slower download (Roku box), skype choppiness, and download that stop. I was thinking that perhaps if I upgraded the firmware, my performance might improve. After reading the sticky, it seems like firmware may not be the answer. This is a reliable but older piece of equipment, and now I'm thinking that I just need to upgrade to a newer and perhaps more advanced router.
I'm using a wireless g router (f5d7230-4) which for most purposes is fine? Specifically: 1. I can't seem to stream media content from my windows 7 pc to my lg tv (model 55 lw 6500), and wonder if the age of the router is part of the problem; 2. some iptv channels on my ps3 are slow to load menus, though programs run fine when I push play (I gather ps3 is restricted to wireless g but if I upgraded the router I would plug in the ps3 using cat6). When I speed test my internet connection I'll typically get results around 2.5-5 Mbps. I'm impressed that a router of this age performs so well it isn't obvious to me that upgrading will improve the setup.
View 1 Replies View RelatedI've recently acquired a Linksys E1200 router--which is more than a week old--from the recommendation of a friend of mine. The service is great and all, but the one thing that frequently bothers me is the seeming constant instability of my router's model. There are moments when the router performs smoothly, but there is as much an instance because the router doesn't seem to work at all even when the lights (and the accompanying connection) on my modem seem to be working in good order.
I know that a router will always have its problems, but this is really a constant problem with the E1200; and if so, if there's any way possible on how I can be able to "stabilize" the said router's performance.
We want to implement multicast on our network. We are going to use for online teaching purpose. I am very new at Multicast and not have much idea about it. We are not running any routing protocol in our network, only static route. The multicast server is located at One of our office and it is connected with L2 (Cisco 2960) switch, L2 switch is connected to L3 switch(Cisco 4948). L3(Cisco 4948) and Core Switch(Cisco 6509) with FWSM are connected with E-3 link with tunnel. Router 1 and Router 2 are connected with P2P ILL links which are terminated at serial interface. The Multicast Server IP is 192.168.2.131/25. The scenario of our network are mentioned below:
Multicast Server--->(L2 Switch)--->(L3 Switch)--->(Core Switch)--->(FWSM)--->(Router 1)---->(Router 2)--->(L2 Switch)--->(Multicast Client)
We have created a seprate vlan (i.e. vlan 102, interface IP is 192.168.2.129/25) for multicast at L3 switch, enable multicast routing, defined rp-address(i.e. 192.168.2.129/25), enable sparse-dense mode at multicast vlan as well as at some other vlan also for testing purpose and joined multicast group (i.e. Multicast IP is 224.3.3.5). At core switch we have also enabled multicast routing, defined rp-address (i.e. 19.268.2.129/25), enable sparse-dense mode at user vlan and inside vlan of FWSM and joined multicast group at user vlan and inside vlan. At FWSM we have enabled multicast routing, defined rp-address(192.168.2.129), doesn’t find any option to enable sparse-dense mode and joined Multicast group at inside vlan and router 1 vlan. At Router 1, we have configured the same thing. We have configured mroute at all the devices. We are able to ping from end to end. We are testing multicast by Multicast IP checker tool (provided by vendor). Multicast is working fine at L2 switch, L3 switch and Core Switch, but not from Router 1. Ping is reachable from Router 1. After doing mtrace at Router 1, the following output has come:
Router 1 (Mtrace with destination address 192.168.2.131)
mtrace 172.21.15.2 192.168.2.131 224.3.3.5
Type escape sequence to abort.
Mtrace from 172.21.254.50 to 192.168.2.131 via group 224.3.3.5
From source (?) to destination (?)
[Code] .....
If , we do mtrace from gateway IP address(i.e. 192.168.2.129) as destination address then mtrace is getting completed, but if mtrace is done from Mutlicast server IP address(192.168.2.131) as destination address, then mtrace is not getting completed.
We have connected one laptop at Router 1 vlan to test Multicast. The host, which is connected to Router 1 vlan is able to send multicast packet to other host and other host at different vlan are receiving it , but it’s unable to receive multicast packet send by other host of different vlan.
Do I need to enable igmp snooping at L2 switch, L3 switch and Core Switch ? I am not able to understand or can't figure out where i have configured wrong.
I have implemented in my company network recommended by cisco scheme with MEC etherchannel from some segment distribution layer (VSS) to core switches (legacy 650x) exactly as on picture: Core switches have rather old IOS (Version 12.2(33)SRB4 and i have reasons not to upgrade it now) which dont support many functions - like BFD over Etherchannels and Enhanced PAgP. And we run a OSPF/MP-BGP/MPLS bunch over those links with OSPF reference bandwidth configured to such values that failure of one link in etherchannel will not lead to link cost changes (we dont have a lot of traffic for now on those links and 1 link can handle it easily) and consequently will not trigger changes to RIB and BGP topology table.
Problem is that i am afraid that in case of one of link of portchannel will fail (but without port down event - unidirectional link or smth else) it will take rather long time to converge - and im talking about L2, not L3 protocols. Cos i cant implement BFD and ePaGP over this link - best i can do that improve 30 seconds PAgP hello timer to 1 second. But at least 3 seconds of possible traffic blackholed - is rather big problem.First time i considered 2 possible solutions:
1) BFD - but even i can use it, it will not improve much recovery time cos 750 ms for BFD over etherchannel not much better that 1 second PaGP fast timer.
2) ePAgP - as i understand this protocol have enhancements to discover failed link faster and improve recovery time, but all information i can find about it - is how to use it for dual active detection and none about timers improvements. So i cant be sure that i should upgrade IOS on Core switches and it will improve my failure detection time. ( if it possible adduce some links to description of this protocol enhancements in comparison with PAGP)
For now im already thinking about using four L3 links (instead of 2 portchannels) and BFD over those links with 50 ms hello timer. But in case of link failure reconvergence of OSPF will take some time, and BGP will react to this no immediately, so i am afraid that even using aggressive timers for routing processes and hellos i will not win much time.

I am implementing a guest wireless network to work alongside my internal network. The guest network will use the existing switching network and will be separated by VLANs. I have the ASA set so that traffic can get to it and out to the Internet. I can set up a workstation on the same VLAN as my guest network and can route inside my network (strictly doing this for testing purposes). Where I am having problems is with the Catalyst 4506 switches and the ip routing. I had two separate "ip route" statements defined on my switches.
ip route 10.200.2.0 255.255.255.0 10.200.2.254
ip route 0.0.0.0 0.0.0.0 10.100.100.254
I have discovered that the traffic is always following the default route despite the fact that my IP address on my test workstation falls in the 10.200.2.x network. I was looking at documentation and found that it is possible to set up policy-based routing on the core switches. Can you have two "ip route" statements defined like this to segreate traffic or do I have to use PBR for routing (or a combination) in this case? If I define PBR then how does that impact my existing routing? I need to make sure that I can still route the existing traffic while I'm configuring this change.
We have 2 sites, each with 2 x 4506 switches which will be connected togther using an etherchannel. The switches will provide access ports for client devices and will be configured with HSRP to provide gateway redundancy. SW1 will be HSRP active.2 metro ethernet links will be installed in each site which will connect back to our HQ sites. OSPF will be used over the backbone to provide resiliency and to allow shortest path routing to each HQ and to prevent traffic over the HQ to HQ link.
The 4506 will be trunked togther with an SVI for providing OSFP adjacency.For the traffic flow from SW2 to HQ2, traffic will hit SW1 and then route back to SW2 and then to HQ2. Is this the best way to do this? Should a second link be connected between switches just for routing or should something like GLBP be used?
I am trying to implement an etherchannel on a cisco 2901 (IOS 15.1). i have already created the port-channel but i cannot assign the gig interface to the channel group.
View 1 Replies View RelatedI have a 3560-48 switch running Cisco IOS Software, C3560 Software (C3560-ADVIPSERVICESK9-M), Version 12.2(44)SE3 and i need to implement basic QOS commands to the fast Ethernet interfaces as well as the gig interfaces and Also I need to create port channels on the switch and need what the port channel syntax are as well for that particular IOS version?

CiscoSwitch1(4506) has 3 VLANs(12,13,14) and Switch2(4948) has 3 different VLANs(22,23,24) and IP routing has been enabled in both switches with SVI interfaces for each vlan. intervlan routing is works fine.Now there is a requirement to connect these switches together. Vlan 12 on the Cisco switch 4506 has to be made available from vlan 22 from Switch2(4948). basically Vlan 12 is having a multicast source (225.0.0.0 & 226.0.0.0) which should be accessabile from vlan 22 of cisco switch 4948.I got 2 ideas
1) Create a trunk between these switches and configure L2 vlan(12) in cisco 4948...i know theoritically it should work but what my concern is Ip routing enabled in both switches will it create any issues? is it a gud solution to this requirement?
2) Create a separate IP network on the ports connecting to both switches and set up routes to the networks.ex- console(config)#ip route 192.168.10.10 255.255.255.0 192.168.20.1.
I'm trying to implement the UDLD protocol (Cisco-compatible), but face some problems. There is no enough information for implementing this protocol neither in RFC 5171 [URL] nor on [URL] How can I get a more detailed information regarding protocol state machines and timers?
View 2 Replies View RelatedI have attempted to implement DHCP snooping and have been having some strange issues. I have 5 3560s taht I use for my edge and when I attempt to implement on all five, the VLAN that houses my voice data appears to no longer be able to recieve DHCP lease renewals so after the 24 expiration all of my phones lose their configs. Once I roll back the changes the voice VLAN comes back. The other VLANs seem to function correctly as theya re able to renew their DHCP addresses.
The 3560s tie into each other using GIG Ports 1 & 2 and the top and bottom switches tie into our core switch, a 4507. The config that I use is below, failry simple and straightforward.
4 of the 5 switches feed our general office vlans for voice and data however the 5th switch is there for expansion and not in use. As such I have left the config changes in place on it and have tied myself and a colleague into it and have been operating fine for over a week now. So the config that I use seems sound in theory and should work on the other 4 switches with no issue.
I'm in the process of upgrading my 4507R core to a new 4507R-E. The old switch has Sup IV engines (WS-X4515) running IOS 12.2(40)SG and the new switch has Sup 6L-E engines running 15.1(2)SG. I'm trying to "move" my configuration from the old switch to the new. Below shows the commands configured in the old switch. I'm trying to determine how to implement the same configuration on the new switch since these commands are no longer available.

We are attempting to PXE boot from clients obtaining their DHCP lease information from DHCP pools configured on our 4506. The PXE server, and the client are configured in separate VLANs. We have configured option 66 to point to the PXE server IP address, and the bootfile option to point to the PXE boot configuration filename. On the client side SVI, we also have configured the ip helper-address command to point to the PXE server (which also acts as another DHCP server for redundancy).
The PXE boot continuously fails stating it is unable to find the configuration file. If we remove the DHCP pool from the 4506, and allow the client to receive their DHCP lease info from the secondary server (Windows 2k8 - same server as PXE server), they PXE boot with no issues.
We have no problem obtaining DHCP info, just completion of the PXE process.
Does SUP 7E is comatible with IOS? It came with IOS-XE preloaded and there are no IOS software listed under downloads.

When I'm rebooting the Device it is not taking the new IOS. It's booting with the OLD image. Even It's not showing any error message while rebooting (ACTIVITY FILE ATTACHED FOR YOUR REFERENCE) I can't take risk by deleting the old IOS.

some recommendations for product selection and overall infrastructure setup for our datacenter: We have an old, legacy setup, and are looking to replace equipment, improve performance, enhance security, and implement hardware redundancy (if cost effective).
1) We now have (2) IP blocks from our provider, and need to support both (because we have mailers on older IPs with a good reputation rating).
2) We have (2) aged Sonicwalls, one for each IP block, each connects to multiple internal subnets (some internal subnets need connectivity to eachother, some don't).
3) We have (mostly) public facing web servers (Linux/Apache), as well as database servers (with no external access).
Questions-
1) Should we implement a Cisco ASA 5520 w/ or w/o SSM modules for the new IP block (for webservers)?
1a) Should we implement a Cisco ASA 5510 or 5505 for the existing IP block (for mailers)?
1b) Or, can we have multiple public IP blocks connected to a single ASA 5520 (or 2 ASA's w/ failover)?
2) Can we connect both firewalls (5520 and 5510/5505) to a single Catalyst 3550 (or similar) using VLANs, and have 6 - 10 VLANs for webserver subnets, with ACLs controlling which subnets/servers can connect to eachother?
2a) Should we implement a second Catalyst 3550 (or similar) for redundancy (webservers have multiple network cards).
3) From our provider, we only have (1) dmark which both IP blocks connect through. Currently we have a switch connected to the dmark in order to 'splice' the connection, and have both existing firewalls connected. Is there a better approach to this?
4) We would like to implement SSL-VPN, and possibly site to site IPSec VPN, but only if there will not be significant performance degredation.
5) Other thoughts/recommendations for new features, enhanced security, or redundancy?
We have just purchased and installed a 4506-E chassis. It contains a supervisor, two POE blades and 3 non-poe blades. Version is 12.2(53)SG1. Anyhoo, one of the ports isn't providing power to an IP phone. We can plug the phone into any of the other POE ports and it works fine. Is there a way to test an idividual port for POE problems? What could the problem be? The port works for normal data but will not provide power.
