Hi Netpro

Just got 4506 including SFP Module,GigaEthernet Module and need guidance to get it properly configured.

All Hardware Installed by Vendor, I will connect 5 Switches and 10 Server to the box. All Server under One VLAN

All switches are cisco 2960,3550


what config is required to connect switches and server on 4506 and on switches 2960,3550


Vlan 3

name Server

ip address 172.20.1.0 255.255.255.0


Each Server has Two NIC for redundancy



4506 is a new box, do I need any license key or serial to activate the box.



cheers

TOM

Ganesh,


Thankz mate, can you share Routing Protocol document from cisco academy



Native VLAN is configured for Managment VLAN or User VLAN.

Considering 4506 is BackBone


SW1 Giga 0/0 connects to 4506

SW1 Giga 0/1 connects to SW2 Giga0/1

SW2 Giga 0/0 connects to 4506


Can this could cause a loop, if so how to overcome it.


Do I need STP config on my setup

Native vlan should be neither the management vlan nor the user vlan(s). You should choose an unused vlan for the native vlan and allocate no ports into it.


Yes you will have a loop with your above setup. You could connect the switches differently but bear in mind STP will take care of the loop and block one of the links. Your switches will run STP by default. A lot of L2 networks do have L2 loops to provide for redundancy so there is nothing inherently wrong with a L2 loop as long as you run STP.

What is the other option of connecting the switches to avoid loop.

2960 you dont need to configure "encapsulation dot1q" command on trunk ports, is this true.


Improper config of STP can cause serious issues, can you guide what is needed for STP config on BackBone sw and user SW



All Server have more than one network card, teaming option is available on server,what is needed on switch as config.

Hi Tom,


For stp configurtation check out the below links about understanding of STP operation and commands to configure STP in switched network.


http://www.at2.com/downloads/documents/adtran/adtran_span_tree_config_guide.pdf


http://www.cisco.com/en/US/docs/switches/lan/catalyst2960/software/release/12.2_25_fx/command/reference/cli3.html#wp1946050


and for etherchannel configuration as you need to do for server to switch communication for making a bundle port at switch port for increasing the bandwidth pipe for server check out the below link for etherchannel configuration at switch end.


http://www.cisco.com/en/US/tech/tk389/tk213/technologies_configuration_example09186a008014edfa.shtml


Bundling need to be done by LACP protocol or you can make hardcode etherchannel on at switch end to have bundling between switch and server.


Hope that clear out your query !!


If helpful kindly rate the useful post.

Ganesh,


Document you shared is CATOS and not IOS for Etherchannel


Can EtherChannel be performed with

Server NIC#1 connected to SW1

Server NIC#2 connected to SW2

Hi Tom,


But there is not much difference in cat os and cisco ios check out the below link for cisco ios for ether channel configuration.


http://www.cisco.com/en/US/tech/tk389/tk213/technologies_configuration_example09186a0080094647.shtml


and server both the nic needs to be connected to same switch in order to have ether channel between the switch and server check out the below link hope this clears out your query !!
