Cisco Switching/Routing :: 3560x - Lan Base 4900M Can Take Load Of 18 Access Switches
Feb 6, 2012
We are using 18 numbers of 3560X -Lan base series switches in our network(Access layer). We have 400 users and created vlans in access switches. we are planning to purchase Two numbers of 4900 M as Core layer switch and for redundancy. The uplink would be on 10 gig copper cable (CAT 7) between the access layer switches and core switches. I like to know whether 4900M can take the load of 18 access switches.

why Cisco make 3560x switches with Lan Base(no routing functions)? What happen if I load an Image L3, previously downloaded? my device lost the warranty? or it doesn matter?

We have to cisco WS-C4900M with Cisco IOS Software, Catalyst 4500 L3 Switch Software (cat4500e-IPBASE-M), Version 12.2(53)SG5, RELEASE SOFTWARE (fc1).We have four gigabit link connected between those two switches.We have create a LACP port channel with those four ports on both switches. Ether-channel is up and running and defined with a load-balancing method of src-dst-ip.But when we test the load-balancing, it's not using the src-dst-ip rule with the XOR: [code]

I'd like to know if is it possible to load lan base image on Cisco Switch 2960 TC-S. This model (WS-C2960-48TC-S) come with lan lite image and it's the same (phisically) of the 2960 TC-L (lan base image).If I try to upload the lan base image on flash of 2960 TC-S will works?? ..or the switch goes damaged?

I have an issue with couple of Cisco 4900M switches. We just got them and tried to use the TwinGig Converter on the 4 ports 10G module.
The problem is that the switches sees the new module in slot 2 and when we are inserting the TwinGig Converters we are getting the error message and when we are trying to type the command this command it does not work."hw-module module <slot> port-group <group> select gigabitethernet",When we go to config T, the only thing we can type is "hw-module module <slot> and if we do a ? the only thing is available is logging and power and we can't type
Port-Group or anything else. Is this a hidden command or we have to something else?

There are two Cisco 4900M L3 switches and two Cisco 2960 L2 switches. I need to configure the two L3 switches to operate as a redundant pair, as the servers connecting to them are connecting using bonded interfaces, which can only have one default gateway. So these two L3 switches need to have the same Vlan interface 1, 2 and 3 IP's set onto them.How are the two L3 switches made aware of each other? via a normal trunk? Is there some special configration for configuring a mated/redundant pair of switches? or are they both just configured as though they were the same switch, but linked?

I'm building a wired closet to aggregate user's connections, Im planning to have 5x 3750X stacked switches and there is a need to run EIGRP, I'm thinking to order one switch with IP service image while the rest will run IP base image, is it workable scenario and what are the drawbacks of such combination of images ?

My management has tasked me to give them a high level overview of the different switching we can choose for our new building.
This is what I know so far.4 Closets, each closet has 450 ports,One MDF room that is will contain one UCS Chassis and a Nimble iSCSI SAN.
I am working on the spreadsheet and it looks like this (Not totally filled):
2960s3560x3750x45064510Approx cost (Each, 48PORT, POE+, 10G uplink, Dual PS, IP BASE)

Layer 3 optDual SupsDual SupsConExpensiveExpensiveConNo Dual PSConLayer 2 OnlyCannot stack more than 4
For the MDF I would like to use 2 Nexus 5548's with FEX's, and the layer 3 daughter board. For the IDF's I was thinking of two 4010's.

1)For 3650X I found some contradiction in the Q&A about feature set LAN Base vs IP Base:
LAN Base: Can I do static IP routing ?
LAN Base: SVI => is this for intervlan routing ?
2)For 2960, there are 2 flavors (LAN lite and LAN BASE) Q: Can I do static routing on one of these flavors ?

I have a WS-C3750X-12S-S (IP Services) that I THINK I'd like to downgrade to LAN Base so I can stack it with a WS-C3750X-48T-L that is already LAN Base..

I'm planning to use 2 3560X (access switch) on two different locations connected over two 2921 routers in small ring. 3560Xs are directly connected via fiber. Each 3560X is conected to its own 2921, and 2921s are connected together with GRE over IPSec. So they are creating ring.I'm planning to use small area 0 in this scenario. There are less then 200 routes in the network. Will 12.2(55) IP Base on 3560X support this scenario or I will need IP Services image? "OSPF for routed access" is still little vague to me, there are only tipical case study scenarios.

I've got a bunch of 3750-X switches all running IP Base and acting as a routed access layer. They run OSPF in a totally stubby area with the distribution layer (Nexus 7K) as the ABR. We also have a physically separate management network into which the fa0 management interface of the 3750-X is connected. The management network itself runs OSPF and has multiple subnets and external access.
On the 3750-X, I'd ideally like to be able to run some sort of separate OSPF process for the management network or at the very least have a static default route for management traffic pointing out the fa0 interface, but clearly not have it interfere with the main default route for data traffic coming from the N7K ABR. Normally I'd just create a management VRF, sling the fa0 interface into it and run a separate OSPF process in that VRF. The problem is you can't create VRFs in IP Base! Surely there must be a way to do this? Cisco don't really expect customers to upgrade to IP Services just to have a working OOB Management network, do they?!

The best option for load balancing between 2 X Cisco nexus 5548UP switches located at one site and connecting to 2 X Cisco nexus 5548UP switches located at another site.
The sites are connected via a 1GB fibre connection. I am unable to use GLBP until GLBP is supported in further software releases.

I am trying to understand what load balancing method is used on a port channel on a Nexus switch . I have a server connected by a VPC to two Nexus switches. The nexus switches are only acting as layer 2 switches. I have a 6509 connected via a upstream link that does all of the routing for my VLANS. If have a server connected to the Nexus switches and it talks to a server on my 6509 what load balancing happens on the Nexus going across VPC 27 which is a layer 2 trunk going up to my 6509. Is it done on layer 2 or layer 3 flows?
My Nexus shows the default load balancing configurations
Port Channel Load-Balancing Configuration:System: source-dest-ip
Port Channel Load-Balancing Addresses Used Per-Protocol:Non-IP: source-dest-macIP: source-dest-ip source-dest-mac

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".

I 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.

I have this 4900M running version 12.2(54)SG1. I the log I get this 3 lines:

They seems to be coming on regular basis, repeating every minute. I've tried Google and the most relevant info I can find is this {URL}. 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?
