I have a 2960G that I keep on the bench as a work switch. I assigned an IP address to it. The techs have had trouble imaging workstations using GHOST. Do any config changes need to be made to enable multicast to work? Everything is in VLAN1 at this point and the GHOST server is also the DHCP server.
View 1 RepliesMulticasting. The configuration is I have a 6506 as my core switch receiving multicasts from an interface assigned to VLAN10. I have a monitor port setup with a PC running Observer which says multicasts are being received on the core switch. On a different interface on the core switch I have a 2960G switch connected to it and this interface is on VLAN 10. The 2960G switch has a workstation connected to it that needs to receive the multicasts. How do I configure the 6506 and/or the 2960G to process the multicast traffic?

one of our switches (WS-C2960G-24TC-L). When I try to turn on the lanbase-routing feature using sdm prefer lanbase-routing, it gives me an error (Unknown command). I tried "sdm prefer ?", and lanbase-routing wasn't there (only qos, default and dual IPv4 & IPv6). The switch is running on image C2960-LANBASEK9-M version 12.2(50)SE5.We have another switch (WS-C2960S-24TS-L), running on image C2960S-UNIVERSALK9-M version 12.2(55)SE5, and I can enable lanbase-routing feature. If I upgrade the WS-C2960G-24TC-L to version 12.2(55)SE5, will it be able to do inter-vlan routing? Or is the switch itself totally limited to VLAN configuration only?

I am now trying to upgrade those switches with the new release, 15.0(1)SE3, however I seem unable to do it, I have tried this on two switches so far, both have been upgraded to SE2 just a couple months ago or so, and both of them will not accept the SE3 upgrade, basically, I can select the tar file in the web browser and click "Upgrade" but when I do the status never changes from "Loading the tar file to the switch". I have tried multiple times from multiple computers using many different web browsers, including IE6 which is listed as supported. I have let it go for as long as 1.5 hours but to no avail.I also had a few idential switches here that had never been upgarded to SE2, I have had no problems loading SE3 onto them using the same method so it would seem that the tar file I have downloaded is valid.

I recently changed jobs and at the new location we are primarily running Catalyst 2960G series switches with the exception of one 3750. All of the switches are setup in a cluster with the 3750 being the cluster master. My question is what is the benefit of switch clustering? The entire network seems to be a bit over engineered for the our needs and I am hoping to scale it back a bit. For example, the the network was setup with VOIP QoS when there were no plans to even use VOIP. Also what procedures would I want to follow to disable the cluster to avoid any major outages? Assuming there is no real need for a cluster.
View 1 Replies View RelatedI'm trying to decide what switch to use as a core for 500 users. I'm currently looking at either 2 x 3750X stacks or 2 x 4500s with dual SUPs and PSUs, both options will provide the number of switchports required without the need for additonal access layer swiches. Which switch option is best to go for here? All of our services will be located in our data centre which will be connected using 2 1000Mbps MPLS circuits. I wont need any advanced L3 features and we are not likley to scale over 450 users. Also is it ok to use the dual switch stacks or chassis to provide the collapsed core/access layer or is it best to have a dedicated core (using one of the above options with less switchports) and having a dedicated accesss layer using 2960Gs for example. Our structured cabling terminates in a single comms room so we wont need to distribute switches throughout the office.

I am unable to configure an interface using the "ip igmp filter <profile #>" command on a 2960G running 12.2(58)SE2. The switch allows me to create a profile using the "ip igmp profile <profile #>" global configuration command. It also lets me enable filtering with the global "ip igmp filter" command (which I didn't see in the documentation). But, the command is not accepted when configuring an interface. "ip igmp ?" does not even show "filter" as a valid auto-complete when in configure interface mode, and the command is rejected if I try to enter it.
I verified the command worked on a much earlier version of IOS, so it must have broken somewhere along the line. I'm wary of moving up to 15.0(1)SE. Is that a major IOS change?

View 2 Replies View RelatedI have a requirement to monitor downstream data feed from a remote site and feed it to multiple destination devices for recording. The source data will be fed into a port on a Cisco 2960G switch then, using the monitor function, be forwarded to multiple interfaces. This works fine for normal Etherent II traffic. We tried a test using a device that generates IEEE 802.3 Raw packets ('type' field is used as a 'length' field) but found that while the traffic appeared to be accepted by the input port with no errors it was not forwarded to the destination ports, even when using the monitor function. I did try the 'encapsulation replicate' feature with no luck. It does not forward these packets even if I set all the ports into a common VLAN and let the switch just perform a normal switch function (non monitor).
if it is possible to get the IEEE 802.3 raw packets to pass through the switch and if it is, how to or what I need to do to make it work?

View 6 Replies View RelatedWe run a network of several 2960G and 3650G switches in a network with a number of VLANs. One one particular VLAN (let's call it VLAN 10) it appears that non-broadcast traffic (i.e. normal unicast traffic) is being copied to every port in VLAN 10 only on one switch . The traffic is not crossing trunk ports and does not appear on other switches that have ports in VLAN 10. We first spotted this by noticing that a UPS port had an unusual amount of activity on our port througput graphs:
This traffic at 4 am is not expected and this profile is repeated across all ports in VLAN 10 on this switch (a WS-C2960S-48TD-L stack running IOS 15.0(1)SE3)\iffed one port using local SPAN (the UPS port) and discovered that this traffic was not broadcast, which was running at a normal low rate at all times. The traffic appeared to be unicast traffic from other ports of the sort you might see on a hub. It was from various hosts that live on VLAN 10, most (not all) of the conversations had one end station homed on the 'problem' switch. There are about 800 non-broadcast packets per hour and this is a busy VLAN so it does not account for all the traffic on the VLAN.
I am unable to access a series of switches connected together through a management vlan. I receive the message "The server xx.xx.xx.xx at level_15_access requires a username and password." Entering the username and password fails and the same username and password message returns.

How can I check the username and password for access with the browser?

I just got a Cisco 2960G 24-port gigabit switch so that our HP servers can have a Gigabit connection to the network. I moved 2 servers to it (HP Proliant DL380's) but they don't actually seem to be able to achieve even close to 1000Gbps. I ran same some LAN bandwidth tests and it was showing only around 200-300 Mbps between all of them. I also ran a network stress test utility, LAN Tornado, and it was showing packet loss as high as 60% when on gigabit, and only .07% when on 100Mbps.
-Both the NIC's and the switch ports are set to 1000/Full
-Currently using Cat5e cabling no more than 25Ft in length (I know Cat6 would be better but Cat5e is supposed to support Gigabit)
-All servers are on the same VLAN
Here are the port statistics when running just a stress test @ 10Mbps that had a 45% packet loss. What's odd though is when I set the servers and switches to 100Mbps, I get less than 1% packet loss.

I’m having issues with enabling Apple’s AirPlay services on a relatively simple network consisting of a Cisco 881 (Advanced IP Services) and an autonomous Cisco 1142 AP. I’ve attached a diagram explaining the connectivity. I believe I have to enable IP Multicast at the router, but I’m not really sure the best/right way to do it. Also I’m not sure what/if any commands would be needed at the AP.All of the wireless clients are confirmed to be in the same subnet, so no real routing is happening etc. Also regular Internet connectivity/routing from the wireless clients is fine.
View 5 Replies View RelatedI start configuring Cisco 2821 router for multicast . First short description and attached sheme explanation. Let we say I have small network with 100 users. One router and Cisco switch 3560. Two VLAN’s, one for data another for multicast. Data from internet works fine but now I want to connect multicast servers (or source of more multicast streams) from another subnet. Router have three interfaces.I expect there should be no problems with multicast configuration, but unfortunately it is not like I expect. What I did ?
First step: enable multicast routing
Second step: on both interfaces (Fe 0/1 and Fe 0/2) - ip pim sparse-mode
Third step: configure switch that users are connected to access port in VLAN 222 (temporary to see if multicast work)
When I start VLC on computer nothing happend. If I try to connect computer on same subnet where is source of multicast streams it works fine.What I am doing wrong ? Is there anything about routing ? All subnets are directly connected. RP is not needed if I have one router or ?
I have a problem on my catalyst 6509 on which I would like to do the following things :
I have some Vlans in which multicast is enabled.
In tose Vlan theres is a router which is default router for equipements.
I had enabled multicast routing because some Vlan needs to exchange multicast informations, but I wolud like to make difference between Multicast traffic. For example I have 5 vlans:
Vlan 1 and 2 need to exchange Multicast informations but the don't need multicast information from Vlan 3 and 4
Vlan 3 and 5 need to exchange Multicast informations but the don't need multicast information from Vlan 1 and 2
Vlan 5 is independant Vlan but doesn't need to have multicast information from all others vlan.
Last problem, equipement on differents vlan can use the same Mulkticast group address. In this case, Multicast routing is not working between Vlan 1 to Vlan 2 and Vlan 3 to Vlan 4.
I 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)
Sample Diagram:
->3560
|
6506 --> 4506 --> 3548
| |
| --> 2960
|
4506 --> 2960

-->3548
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.
