Cisco Switching/Routing :: Stacking Or 10GE Link Between Two 3750

Jan 22, 2013

We have two 3750 stackable switches in core layer.
 
1. We are planning to stack two 3750 for greater bandwidth to use
 
2. We could configure 10GE link (by Network module) between these two switches
 
which solution provides increased bandwidth and redundancy?

Cisco Switching/Routing :: Stacking 3750-X With Universal Image With 3750-G Running BIN Image?

Oct 10, 2011

I'm looking at adding a Cisco 3750-X switch running c3750e-universalk9-mz.122-55.SE1 (IP base license) into a stack of 3750-G switches running c3750-ipbasek9-mz.122-55.SE1.bin Given that the version and feature sets are the same I don't forsee any compatibility issues. Would there be any reason why a universal image wouldn't stack correctly with other switches running the single .bin file?

Cisco Switching/Routing :: How To Monitor 3750 Stacking Port In LMS

May 24, 2012

I would like to ask about 3750 stacking and some Cat6 stuff...
 
1) How do we monitor 3750 stacking port in LMS?
2) Let say if I stack 3 switches, middle switch should be Master. Uplink should be at Top and Bottom. Is best practice?
3) Can we mixed 3750G and 3750X and what is result internal BW - fallback to 32Gps?
4) is there any Qos difference between WS-X6816-10G-2T and WS-X6816-10G-2TXL?
5) is there any Qos difference between MSFC5 PFC4 and MSFC5 PFC4XL?
6) What is main difference between PFC4 and PFC4XL in Sup2T?
7) Pls share more about Central and Distributed Switching in Sup2T and which card support Distributed DFCXL?

Cisco Switching/Routing :: Build Improved Redundancy Into LAN By Stacking Two 3750

May 1, 2012

I plan to build improved redundancy in to my LAN by stacking two 3750s and teaming pairs of NICs on my Dell PowerEdge servers, with each cable of the pair going to a different switch.In my mind this provides redundancy for the NICs and the switches. Does this configuration will work, and also what type of teaming is supported, as I was planning to have one NIC active and one standby, but can I run this configuration with both NICs in the team as active with load balancing?

Cisco Switching/Routing :: 3750 EtherChannel / Stacking In Core Layer

Nov 23, 2011

As we know there are three layer in cisco Network Model:
 
-Core
-Distribution
-Access
 
So my question is  in Core / Distribution layer should i use Etherchannel between switches or use Stacking if switches are stackble.For ex: suppose I have two cisco 3750 switches . so should i use etherchannel between them or use stacking in core layer?What are the advantages and disadv of both.

Cisco Switching/Routing :: 3750-X Stacking Switch By Switch

Nov 18, 2012

I have two 3750-X configured to be a stack and I am planning to re-rack these somewhere else.  What I would like to know is what are the effects of having the master switch itself lose power?  Does it immediately just make the member take over master (there should be no election since there are only 2 switches??) and there would be no loss of connectivity?

Cisco Switching/Routing :: 4948 10GE Red Status LED?

Jun 5, 2013

We had to transport one of our 4948 10 GE to another Data Centre and when we got it there and tried to power up its System Status LED was red and we cannot even get console to the device.
 
We can try to see if the switch is completely dead and needs replacing or is there something we can do to get it back up and running again?

Cisco Switching/Routing :: 10Ge Between Catalysts 6500

Nov 18, 2012

I am in front of a choice what to select to deploy 10Ge in my datacenter to get four 6504e and two 3750x units connected to each other.All devices are located in 3-7 meters away from each other.The choice is whether to go for a multimode fiber and 10GBASE-SR X2 Modules OR cat7 UTP and 10GBASE-T X2 pluggable transceiver.Money wise it doesn't matter.Fiber looks less attractive since it's fragile and a bit harder to put in underfloor area.Cat7 is more attractive but there are 2 points:

1) I couldn't find ANY single photo of a 10GBASE-T (a module with a single RJ45 port). How does it look? Does it come with a cable or...??

2) How stable is it to run 10Ge over UTP?

Cisco Switching/Routing :: 4510R - SUP V-10GE Uplink

Jan 28, 2013

I have a two Cisco 4510R each with two sup V-10GE redundant. The code on these sup modules are 12.2(31r)SG3. I need some assistance in getting this setup worked out. I have all four of the 10GE populated with appropriate optics. I setup a link from one 4510R to the other using these interfaces. From the documentation I found I had to use Tengi1/1 and Tengi2/2 as the redundant pair. I plugged the up link into these ports. The Tengi1/1 (active supervisor) links up and works fine. But when I look at the ports port Tengi2/2 it isn't showing link or active. Now port 2/1 (nothing plugged into it) is showing as active.
 
Now is the redundancy supposed to be 1/1 and 2/1? If so, the switch is in production, when I move the connection over from 2/2 to 2/1 will it cause a outage? The reason for this is I now have a system with a 10G port and would like to utilize one of the other 10G ports. Is that possible? Or does it have to be a lag/redundant up link to work (say to another switch)?

Cisco Switching/Routing :: RP / Input Drops On 6500 Sup 720 10GE

Jun 17, 2012

What does RP drops entail? We are experiencing 0.23 % drops on an vlan int on one of our 6500. This interface is an L3 to a server-subnet. Doing a sh int vlan 238 switching shows 30935411 RP (Route Processing) drops.It was a bit unclear to me in the thread "Input queue drops on 6500 vlan interface" if RP drops was through the router, or to the router(mgmnt)?I can do a netdr to see what traffic goes to it. It should not generate CPU load, but I think I will wait until after hours before I try that command.

- do NETDR:
-- debug netdr cap rx vlan 238
-- show netdr cap

Cisco Switching/Routing :: Add WS-X6716-10GE Card In CAT6509

Sep 8, 2011

I will be adding two WS-X6716-10GE cards in a CAT6509 soon, and will create 4 port channels with 3 ports each in the new cards, but I do have a few questions:
 
1 - I will be adding cards in slots 3 and 8, can I mix and bundle ports from both modules into a single etherchannel, I mean, like two ports in slot 3 and 1 port in slot 8 to create a PortChannel ?! Or can I only bundle ports in the same card/port-group in a Etherchannel using this WS-X6716-10GE card?
 
2 - Do I need to issue the hw-module slot x oversubscription port-group y command in order to be able to bundle ports in the Etherchannel I need to create ?! I will be using 4 Etherchannels (LACP)  with 3 ports each, running in trunk mode. So I guess, I will be using something like:
 
int tengig 3/1
switchport mode trunk
switchport trunk encapsulation dot1q
logging event link-status
[Code] ....

Cisco Switching/Routing :: WS-X4516-10GE Works With WS-X4612-SFP-E?

Dec 4, 2011

Is it possible that catalyst 4500 Supervisor Engine V-10GE WS-X4516-10GE works with WS-X4612-SFP-E?I know suprtvisor engine V-10GE is not support E-serious linecard, but when I use the configuration tool, I can choose these two products together. Is it a bug?I need novell IPX in this case, I find supervisor 6E & 7E are already not support, so I have no choice to choose V-10GE.

Cisco Switching/Routing :: 4507 R-E With Sup 10GE Factory Reset

Jul 29, 2012

I have been trying to reset my Cisco 4507 R-E with sup 10GE engines, and I am not having any luck. I have followed the following document:
 
[URL]
 
I have tried "wr erase" and "erase startup-config." I cannot delete the vlan.dat file either. I am using the command "erase cat4000_flash:vlan.dat" and its not working either. I have done these commands several times with no success. When asked if I want to save the config changes, I am answering with a "no" I have not tried to depress the small "reset" button on the front of the sup engines as I read that this just restarts the switch.

Cisco Switching/Routing :: Setup Management VRF On 4948-10GE

Aug 3, 2011

I am trying to setup the management vrf on the 4948 10GE so that my TACACS requests will use that vrf for out-of-band purposes. The vrf is working properly because I can ping the TACACS server using the vrf but the logins do not work. I see this error in the tacacs debug:
 
TPLUS(00000016)/0: Connect Error No route to host
 
Looking at the release notes, it states that my version (12.2.54 SG1) does support vrf aware tacacs but the documentation seems to be a bit off because i do not get a server private command option as stated in the configuration doc after configuring a tacacs server group:

Here is my config:
 
ip vrf mgmtVrf
rd X:X
!
interface FastEthernet1
ip vrf forwarding mgmtVrf
ip address x.x.x.x

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.
