Re: Best IOS version for 3750 switch

martyvandeveerdonk · ‎08-11-2005

I have just received 2 3750 switches, but both have a different IOS version.

One has -> IOS version 12.1(19)EA1d

and the other has -> IOS version 12.2(25)SEB2.

I just want to use the switches as Gb collectors for a serverfarm seperatly (so no stack configuration) with a redundant uplink to my distribution layer.

Can someone advise my which IOS is the best for my network?

Thanx, Marty

Your switch 1 is with the standard image which is a layer 2 image with some basic routing features only RIP and static routing.It doesnot have advance feature set.

Switch 2 has enhanced multilayer image which has all the advanced feature like routing protocols RIP, IGRP,EIGRP, OSPF, multicast routing, QOS, PBR etc.

So featurewise EMI is the best but it depends on your requiremnt. If you dont need adavnced features SMI works OK otherwise EMI.

In order to upgrade the SMI switch to EMI you need to have additional licence for this.

I would not upgrade the EMI one. That version is great and already has IPv6 support in it. To enable IPv6 on your switch just do:

conf t

sdm prefer dual-ipv4-and-ipv6 [default|vlan]

exit
