I'm setting up a new 4900m running cat4500e-ipbase-mz.122-53.SG5.bin. I'm attempting to create Port-Channels as a Trunk for uplink to a 4503 running cat4500-ipbase-mz.122-37.SG1.bin.When I attempt the command "switchport trunk encapsulation dot1q" it errors out.

I have a Catalyst 4500 L3 Switch Software (cat4500e UNIVERSAL-M), Version 03.02.00.XO RELEASE SOFTWARE (fc2). So I just wanted to verify that the switch only does dot1q encapsulation because the switchport trunk encapsulation dot1q command does not work.
View 3 Replies View RelatedI've been studying my inter-vlan routing , mainly in this case routing on a stick. I noticed through packet tracer that the 2960 switch doesn't allow for the '(config-if)#switchport trunk encapsulation' command, but the L3 3560 switch will.I am very concerened about this since VLANs are a main topic. What perspective will Cisco be seeing this from for the CCNA exam, I test in 12 days. I have embedded a packet tracer screen shot for more information in case I didn't word this right (which happens all the time to everyone it seems like in NW'ing now and then if not alot).

I have typed:

I am looking at upgrading our 4503 to the 4507R+E. Just going through the configurations and a couple of commands seemed to have dropped off this release.
1. I can no longer specify encapsulation type on a trunk. Does the 4507 auto sence encapsulation and apply it dynamically?
2. I had dscp trust configuration as below on the 4503, whats the equivilent on the 4507?
we recently aquired a managed services job and have to do a overhaul of the vlan configs and have a whole dozen WC2948G's trunk between a set of ports as well as trunk out a LAG channel setup to non cisco equipment. the deal is the lacp-channel works properly on both ends but no routing of vlans between ports and between the lag trunk are working.
theres alot of settings in the config and im planning on clearing it and starting from scratch but before i do i want to know where my problem lies.

The last few days I've been exploring options in getting rid of some old routers accross a wan connections. I have a cat 3560 to play with and I thought I would try and use the no switchport command test out routing with switch. I've got some type of route issue and I tried a few things which I thought would fix the issue but had no effect. I'll post the config and a few commands so you can see what the basic setup is.
Here we can see in the arp that it knows about both 10.7.1.2 (PC unable to ping 10.3.3.254) as well as 10.3.3.254 (ASA).I tried adding in a ip route of 10.7.0.0 255.255.0.0 10.3.3.110 as well as 10.3.3.254. Neither produced the results I wanted allowing 10.7.1.2 (PC) to ping the ASA (10.3.3.254). [code]
I created new VDCs. Since I have done so, there is not switchport command under the interface configuration.
The interesting this is that it is available on the admin VDC, but not the new VDC I created. I cannot create a peer VPC Peer link between my 2 Nexus switches. I did allocate ports to the new VDC and I did verify the enabled feature are the same.
why the switchport command is not available?
I have Catalyst 3750 running IOS version c3750-ipservicesk9-mz.122-55.SE.bin. I have an access port that connects to a Redhat Linux version 5.4 64 bits machine. When I perform a "show mac address-table interface g1/0/3" where the redhat machine is connected to, I see two mac addresses on this access port. One of the mac addresses, 0025.9006.4898, belongs the the redhat machine. the other mac address, I have no idea where it comes from. I tried to perform clear mac address-table dynamic g1/0/3 several times but it does not work either.

View 3 Replies View RelatedIf you have a router with multiple direct vanilla FE (non trunked) interfaces on a switch trying to send QOS tagged packets to a wifi bridge several switches away does the trunking in the switched infrastructure mess with the qos tags if no qos is configured on the switches.
Does it depend on the switch? We have new 2960's running 12.2 and a few older 2950's running 12.1

View 3 Replies View RelatedI have a a hardware server running a VM hosting virtual servers which are all on different VLANs. My challenge now is to configure the switchport that the server is connected to, to see all the VLANs needed by this VM. The VM has an IP that is used for managing the server VMs which is on a different VLAN also.
My switch is a 2960 switch and it is presently trunked from the core switch.
I have a Cisco 2901 with the 4port gigabit ethernet switch module that I'm trying to get configured to have a seperate subnet for each port. So far I have it set up so each subnet is a vlan, then on each port I use the switchport access vlan command to tell it which subnet I want that port to be on. However, there is one port that I need to have 2 subnets on. The way I found to do that was to use switchport trunking on that port, but it doesn't seem to be working properly. how they would configure this? Right now I have vlan 101 as x.x.x.17/28 and vlan 103 as x.x.x.53/30. I think where I'm getting hung up is the proper association between the physical port and the vlan subnets.

View 2 Replies View RelatedI have a client whom has a 4900M switch as their SAN switch. They are getting ready to upgrade their SAN to use 10G.I had quoted them a price for an X2 module, but I am unclear based on pictures I have seen of the part number
X2-10GB-SR
whether or not the X2 module plugs into the X2 slot on the switch, AND then also has to have a transceiver put in it to receive the SC ends of the Fiber jumper, or whether the SC ends of the fiber jumper plug into the X2 module directly.

But it says "Upgrade software to IOS version 12.2(52)SG or later OR 12.2(50)SG4 or later. ". I'm already running 12.2(54), so why does this 3 line repeatedly show up in the log every minute.
First time user of cisco hardware and we just purchased the 4900m catalyst switch. My question is very general. I am simply hoping to network 3 servers together and I do not wish to do any fancy or advanced configuration. Can I simply use the web management interface for network administration and setup? I just downloaded the Catalyst 4500 Series Switch Cisco IOS software configuration guide and they talk about Cisco View network management system, is this my answer or is this what most people use for basic configuration and administration?
