I have a etherchannel defined between 2 L2 switches using LACP as shown below. The etherchannel works fine, however when I hard code speed/duplex on both ends the etherchannel fails. What is causing this behaviour?

interface Port-channel5
interface GigabitEthernet1/0/1
switchport mode trunk

The channel consist of two port on both side and is in trunk mode, encapsulation dot1q.Now i have the necessity to connect the 2950 to the other catalyst, 4506B. So, i copy the same configuration on the 4506B, but when I unplug the two rj45 cables from the catalyst 4506A to plug them in the 4506B the etherchannel doesn't go up in any way.

Im trying to determine the serial number of Gbics already installed and running on a Catalyst 2950 switch. Is there a specific command to do so? There is a command on Catalyst 4506 that gives all info regarding the Gbic ("show idprom interface gi 1/1") Is there something equivalent for 2950?
View 4 Replies View RelatedI used to be able to set an uplink port with the interface command "port network" so that it would not learn all the mac addresses that are being flooded down to the switch. It does not seem to be there on the 2950's or 35XX switches.
Where did it go and what is replacing it? Interface is a Trunk port as well.
My switches is still operating but when i ping the switch, there isn't any reply. No icmp reply from catalyst 2950 switch
View 6 Replies View RelatedIf I have two stackable switches one switch uplinks to one 6509 core switch and the other connection uplinks to another 6509 core switch, and also the other stackable switch does not connect to the core switches. Because I am using hsrp and also we are not using vss then one uplink to the core is not in used only ones is so then how does creating an etherchannel between does two uplinks to both core switches benefit me in anyway such as more bandwith and using both uplinks at the same time or I'm I wrong?

Is it possible to have ether-channel across 2 switches? As an example, having a server with 2 ports connect, 1 port to Switch-A and the other to Switch-B and then use those two links on the sepatate switches but to the same server to form an Etherchannel.
The Switch-A and Switch-B are 3560 series
I am wanting to etherchannel from a 3750 stack to core Layer 3 switches (also 3750) with a cable going to each core switch, I have put both core switches and the stack under a 28bit subnet mask, but I dont seem to be load balancing across both links.

interface FastEthernet0/1

interface FastEthernet0/2
channel-group 1 mode on
I thought the port-channel 1 would get automatically created but it didn't, should it? And under the port-channel interface should I set this as a trunk or do I do this on the 2 fa interfaces on each switch?
Is it possible to use two different load balancing methods at each end of a port-channel between two switches?
We have a Cisco 6509 at one end of the port-channel and a Cisco blade switch 3020 at the other end. Right now, we are using "src-dst-ip" at both end of the port-channel. We would like to change this. That is, we would like the #3020 switch to use "src-dst-ip" while the 6509 switch should use the "src-dst-port".
Why we want to do this, the reason is that we have FWSMs on the 6509. I've read that by configuring "src-dst-port" on the 6509, one can get a better performance of traffic going through the FWSM. However, the issue is that the 3020 switch does not support "src-dst-port".
What is the difference between the 2950 and 2950c switches? I tried finding it on the feature navigator but I couldn't. And I wasn't able to get anything from the Cisco website either. (I didn't really look through the long PDFs, I'm sure there is a more simple way to find the answer to this that I'm not aware of.)

View 1 Replies View RelatedI'm having some serious sound problem with some 2950 Cisco switches that I have in my CCNA lab these switches sound like a jet I've gone in and made sure the fans are clean and I even replaced one they still are too loud. So I have a few options I can run them without a fan which I really don't want to do but I want to look at two other options. The first option would be to put a heat sink on the chip that's producing heat I also thought about cutting a whole in the top and mounting a 120mm fan.

I have tried to allow all vlans or vlan 1 specifically and the output of the above doesn't seem to change. I am wondering if there is something in the config-register that is preventing trunking, but I don't really know enough yet!
The output of my second switch is identical to this one, the only difference is that I have it configured as a vtp client.
I am aware that private-vlans are not supported on edge switches like 2960 series - so my question is would it be possibel to ceate private vlans on say just the core switch which would be a 3570 or 4506 that supports private vlans and then just trunk these to the edge like normal vlans?what I need to achive is to have edge port not able to communicate to each other even across switches - which cannot be done using 'protected' port so need the private vlan feature?

View 7 Replies View RelatedI have a number of class-'c's as a hand-off from my data center fiber to my 2960, which then sprawls the racks with about many 2950 switches, mostly 20 machines per switch. To allow machines on one 2950 to push data to another 2950 without routing back to my ISP's router(which costs money for bandwidth) isn't is possible to trunk one port on each 2950 to another 2950 and adding a addititional vlan8 to them. Then data jumps from 2950 to 2950 without going back to the 2960 or mainly not going back to my ISP's router. Is this the correct way to accoplish this with extra vlan and trunking the 2950's to each other or am I looking at this all wrong?
View 1 Replies View RelatedI have more than 20 Cisco switches in my office which is basically a soap manufacturing factory. The switches include Cisco 2950, 2960, 3560, 3750 etc. We have routers also which include 2821, 2951 etc. We also have Cisco WLC 2125 and LAP 1262 series. Sometimes all these devices management comes very tough to us.
We need to log on to different devices for troubleshooting/network management which sometimes becomes very tough to us. So I wonder if there any Cisco applications or tools by which we can centrally manage all these devices.
I am looking into the possibility of using private vlan's for some dmz implementations however I do have what may be some very rudimentary questions. It seems straightforward how to configure the primary/secondary vlan configuration as well as associating them. However in my case I would be looking to configure the PVLAN on a 6500-vss platform acting as the router while all of the hosts which I would desire to have in the isolated vlan would be spread out across a number of older Cisco switches which only support "protected port" setup or Procurve switches all of which I do not have budget to replace with something newer. So in my scenario I would have a 6500 connected by trunk to multiple switches which only support a protected port setup such as a Procurve (top of rack) or a Cisco 2950. As the Procurve or 2950 would not support Private VLAN setup, do I then just configure the secondary vlan to be allowed across the trunk from the 6500, configure that vlan on the Procurve or 2950 (as vtp will not foward the info for the secondary vlan) and assign that vlan to the host port as well as setting it as a protected port and this will communicate just fine across the trunk to the router as well as stopping the protected port in top of rack switch 1 from being able to communicate to a protected port in top of rack 2,3,etc? If the above scenario is what needs to be done, do I just use a regular trunk or do I have to use a PVLAN trunk?

View 3 Replies View RelatedA customer is expanding their network into another wing, and they have a good number of existing Small Business switches (specifically the SGE-2010P - [URL] that they're interested in possibly deploying. They have a full-blown Cisco infrastructure and voice deployment (Cat 6500 core switches, 3750 switch stacks, Communications Manager w/ over 1,000 phones, etc.).
The general concern is whether there is ANY known issues or concerns with trying to mix/integrate the Small Business equipment with non-SMB infrastructure. Looking at the datasheet for this switch, it's clearly PoE, supports QoS, although it doesn't specifically indicate it can provide a voice/auxiliary VLAN for a phone detected by CDP - that would be a big deal. So basically, "a switch is a switch", and I'm just posing this question to make sure there's no reason (technically or from a support standpoint) that we would not recommend integrating these.
I am trying to test (if possible) the idea of having 2 6509-E switches connected directly to each other while using VRF-lite (Sup 2T). The idea is to have 3-4 separate networks. For example Net-A, Net-B,Net-C, Net-D. There is no PE router*, just these two switches. Also, there sin't any other access layer switches. All users connect directly to the 6509-E's via switch 48 port switch blades.
Net-A and Net-B on separate VRF's, but able to talk to each other. Net-C and Net-D* on separate VRF's without being able to talk to any other. Net-D* will have a PE since it comes from an external network. This is something I would like to test in a lab environment, but I am not familiar with VRF's.
I have a 100mbps internet connection from my ISP but once the connection hits the ASA the download speed gets reduced to 15mbps. My network is setup as follows: ISP Modem ---- Edge Switch ----- ASA --- Internal Cisco Switches
If I plug my computer into an extra port on the Edge Switch I get speeds around 92mbps with normal traffic still going to the ASA. But when I plug into the ASA and internal switches I have speeds of 15mbps.
I have made sure that duplex/speed match on the links. I have done packet captures and within two minutes I do have several dup acks and retransmissions. The retransmissions don't seem to match the dup acks. (The retransmission is not for the dup ack requested so the dup ack keeps being resent)
