Cisco Switching/Routing :: Access Layer Switching With 2960 / 3560x / 3750x And 4506

Jan 17, 2013

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):

Cisco Switching/Routing :: 3750X Static Routing When Running LAN Base?

Dec 27, 2012

I have a stack of 2 x 3750X switches these are running 12.2(55)SE5. I needed to add some static IP routes and found that the ‘ip routing’ command is not supported. I came across a document that stated “On switches running the LAN base feature, static routing on VLANs is supported only with Cisco IOS Release 12.2(58)SE and later.” So I have upgraded to 12.2(58)SE2, but ‘ip routing’ is still not a valid command.
 
The release notes state:“On the Cisco Catalyst 3560-X and 3750-X Series, it adds support for 16 static IPv4 routes in the LAN Base image.”
 
I have read other posts that talk about running the ‘sdm prefer routing’ command which I have done, but I am still unable to add any routes or run the ‘ip routing’ command.

Cisco Switching/Routing :: Moving Routing From Perimeter Router To 3750x?

Dec 9, 2012

I have an 1811 with several subnets connected to it.I recently installed a 3750x plant and want to bring my interior routing back to it.
 
All the routing is handled by the 1811 via secondary interfaces on vlan1?
 
I have 192 ports, and subnets show up on almost all of them.  None of the ports are assigned to any specific vlans.  Most ports have several subnets on them.
 
What is the best approach to getting the 3750x to handle the routing?

Cisco Switching/Routing :: Routing Between Vlans On 3750x

Jan 24, 2013

I am setting up a vm environment for a customer in my lab off site. I have two stacked 3750-x switches, a san, and threes UCS c220 M3S servers for hosts. I am trying to separate the lan traffic, san iscsi traffic, and san management traffic using vlans. The problem is i'm unable to communicate cross vlan with my current config, which I have attached to this post. The only noteworthy things in my conifg is that the ip route 0.0.0.0 0.0.0.0 192.168.83.6 is referring to a switch stack they have on site, that I will connect this stack to using the first two trunk ports on each switch, that I do not have here in the lab. I don't want to cause any confusion in why I have things set a certain way.

Cisco Switching/Routing :: Stacking With 3750X?

Jan 1, 2013

There seems to be a lot of conflicting information on what can and can't stack together in the 3750X range.
 
I know that LAN Base can only stack with other LAN Base switches.
 
Can IP Base stack with IP services in 3750X? I have also heard that the 15.x.x IOS restricts mixed feature set stacks?
 
I know that Cisco recommends that all switches in a stack have the same IOS and feature set but having all IP Services in a stack can get too expensive.

Cisco Switching/Routing :: QoS On 3750X Stack

May 7, 2013

I'm trying to review a QoS setup, and I'd like to make sure I fully understand the current setup before I change anything. I'm seeing output drops on two different queue-thresholds, but not sure how packets are making it to one of the queues.
 
Switch Version
CORE#show ver
Cisco IOS Software, C3750E Software (C3750E-UNIVERSALK9-M), Version 15.0(2)SE, RELEASE SOFTWARE (fc1)
System image file is "flash:/c3750e-universalk9-mz.150-2.SE/c3750e-universalk9-mz.150-2.SE.bin"
cisco WS-C3750X-24 (PowerPC405) processor (revision A0) with 262144K bytes of memory.
Switch Ports Model              SW Version(code)

I can find queue4-threshold3 in the mappings, but how are packets getting mapped to queue2-threshold1? The priority queue is disabled for this interface, so I'm not sure how this queue is dropping packets, according to the maps nothing is mapped to 02-01.

Cisco Switching/Routing :: 3750X Power Needs For PoE

Mar 21, 2013

I am building a switch stack using 4 48 port 3750X switches that will also have the power stacked.  If I install a single 715W power supply in each switch will the stack support 802.3af accross all 48 ports on each switch?  My calculations are 48 ports x 15.4W which gives me almost 740W needed which is over hte 715W power supply.  I was reading somewhere were it mentioned that in a powerstack additional power can be drawn from the stack.  I know this will not work if you are trying to support power on all switches accross all ports but would it if say 2 of the 4 switches are needing to provide PoE accross all 48 ports?  If I say we can only use 24 ports per switch for PoE that drops the power need down to 370W which I believe should work.  Just trying to get a better understanding of PoE consumption.  Would the best solution be to just add a second power supply to each switch?

Cisco Switching/Routing :: L2 Vs L3 Between 1002 And 3750X Core?

Feb 4, 2013

we are replacing network equipment at one of our sites. The network will have 12, 3750X switches(6 stacks) - one stack will be the core. A 1002 will be the WAN router to the Main campus. The 1002 will connect to the core via 2 ethernet cables. I'm debating whether to use L3 or L2 between the router and Core. I've heard that routing is more efficient if L3 is used and also I will be able to create an L3 etherchannel  between the 1002 and Core switch. See the attached doc.

Cisco Switching/Routing :: Multicast In A 3750x Stack

Jan 31, 2012

I recently created a stack using (2) 3750x switches. I have three vlans on the stack (1,105,241) Vlan 105 is configured on 6509 core switches with multicasting and are connected to the stack via gigabit fiber. It is working well with clients on the Master or SW1, however clients on SW2 do not participate in multicasting Any client pc that is connected to SW2 vlan 105 does not show up in the "sh ip igmp snooping group" command. I can statically assign a client on SW2 to the mcast groups but but they fail to register on their own. I can take the cable connection from SW2 and plug it into an SW1 Vlan 105 port and it immediately becomes a member of the groups. I can then connect it back to the SW2 port and it disappears from the group membership. IGMP and PIM are configured with the defaults.

Cisco Switching/Routing :: 3750X - Basic Configuration

Jul 19, 2012

We currently have 7 Cisco 3524-XL switches (10-12+ yrs old) which are 10/100.  We purchased a handful of Cisco 3750X switches to replace them going with the whole stackwise and redundant power supplies.  Our current configuration on the old 3524 switches is that they have hardset all the ports on them to 100MB/FULL since devices would auto-neg to 100/Half. Since we're going from 10/100 to 10/100/1000 switches, I want things to auto-neg as I have heard in the past and experienced that things work better when it auto-neg to gigabit.  My upper management is afraid since the old switches wouldn't auto-neg correctly that we should hard set all the ports on the new switches, which would be a nightmare since some ports would be hard set to 100/FULL others to 1000/FULL, etc..  We've tested just about all of our devices at auto with the switches and they've all auto-neg to the correct speed. In short, is Auto-Negotiation the way to go with the newer switches or is it still better practice to hard set your ports?
