May 6, 2013What is the preferred access switch for new deployment. Choosing between 3850 and 3750x. I have to say that the 3850 wireless features will not be used in this deployment and 4 switch for stack is enough... Looked and read everything that I found in the press, I can not make an informed choice. I bow to 3850, but I was apprehensive following circumstances:1) not too positive reviews2) to long list of open caveats3) to long list of features are not supported in Cisco IOS XE Release 3.2.0SE4) IOS XE : (With regard to the first three points - yes, I understand that the product is new and it has not gone further stage of "childhood diseases" ...Regarding the fourth point - I understand correctly that this is the direction to be moving Cisco Systems and soon all products migrate from classical IOS to IOS XE and so on?

May 16, 2013With my brand new Cisco 3850 Switch, I got it configured with a LAN IP. Then, on my PC I opened up Cisco Network Assistant (version 5.8.5.1 which supports the 3850). I went to add the 3850 to the community by discovering the device, and was prompted with the user/pass box. The password I set was not allowing me to connect, and I realized it's because a username was required and I had not set up a username on the switch. So, I then configured an admin user with level 15 privileges on the switch. However, now when in CNA I try to add the 3850 to the community, it doesn't even prompt me for user/pass, it just says "unable to connect".
What do I need to do to add this 3850 to my community?
Cisco Switching/Routing :: 3850 - Web GUI Stuck In Express Setup?
Jun 2, 2013I have configured my new 3850 using the command line and all works well. I logged into the web interface expecting to see device manager with a pretty image of the switch etc.
However I am presented with the Express Setup page and even if i fill in all of the details again and click submit then nothing happens and this is all I can get.
I have version 03.02.01SE software.
Cisco Switching/Routing :: Catalyst 3850 - Normal To See 30% Cpu Usage When Idle?
Apr 18, 2013We have a new stack of two Catalyst 3850-48T's running IOS XE 3.02.00 (we are upgrading to 3.02.01 this weekend.)We noticed the CPU usage is around 30% even when there is almost no traffic going through the switch. We haven't seen any indication that it is causing a problem, but is this considered a normal baseline?I attached my config (with passwords sanitized,) show ver, show controllers utilization, and show process cpu history.
I noticed this behavior is normal on 2900XL/3500XL switches, but I didn't find anything relating it to 3850 switches. Does the same thing apply to the 3850 switches? [code] url...
Cisco Switching/Routing :: 3850 - Link Light On But No Cable Connected?
May 8, 2013I just completed installation of a stacked pair of 3850s in my datacenter. While I was installing them, I noticed that the lights on ports 1-8 on one of the switches were on solid even though there were no cables connected to that switch. I don't see anything in the logs or anywhere else in the CLI that indicate a problem, however the lights remain on. This only happens on switch 1, not switch 2. Once I plugged the cable into port 1, it flashes normally with activity, but 2-8 remain on solid even though nothing is connected to them.
Before I put the switches in place, I had configured them at my desk with the console connection, and those lights were not lit up.
The indicators on the front of both switches are set in STAT mode. I thought initially I had hit the button and flipped it to a different mode, but that is not the case.
Cisco Switching/Routing :: Network Performance - 3850 Versus 2960
Jun 3, 2013I have a network coming up for a switch refresh. Management is pushing for 2960s and I would like 3850s. We are running Cisco Voice and Video over the network. I saw a few things that seemed to be in favor of a Layer 3 switch vs. a Layer 2 switch. Some items like better performance due to switching based on IP vs. switching based on MAC. Some information that will show the 3850 to be a better choice or that the 2960 is capable.
View 6 Replies View RelatedCisco Switching/Routing :: 3850 System LED Blinking Fast - Not Getting Past POST?
May 14, 2013I pulled a brand new Cisco 3850 Switch out of the box yesterday. Following the Quick Start Guide, I put in the power module, powered it on, and waited for it to complete POST. Then, I plugged in an Ethernet cable between a laptop and the switch on a port in the front, and went to the web interface at https://10.0.0.1. I got to the Express Setup, and attempted to change the IP address of the switch to an IP on my LAN, along with other options. When clicking submit, it didn't appear to take. Upon refreshing in the Express Setup, the IP config was blank, so I once again configured it. This time clicking submit brought up a message that it was changing the IP address. I waited for it to finish, and when it looked done, I powered the switch off and took it to a different room to hook it up to the LAN for further configuration.
When plugging in the power at that point, the switch starts through the normal light process (System LED blinks green slowly), and then eventually the System LED blinks green very fast and never stops. It doesn't get to the point of having the system loaded and ready to log into. There's no amber lights, just the System LED flashing green fast. On the back, the Power module and all bay lights are green, and the Console light is green, but the Management port light is off.
I've tried using the reset button on the back of the switch two different times to reset it to default configuration, thinking I hosed it somehow, but it never goes past the fast blinking System LED.
Cisco Switching/Routing :: Catalyst 3850 - Additional License To Enable Controller Functionality?
Feb 10, 2013Based on what i am reading on the Catalyst 3850 datasheet, the controller functionality comes by default if i have a IP Base of IP Services license on the switch.

Differences Between Two Models Of 3850 Switches?
Mar 4, 2013We are looking at doing some switch replacement. These switches will be in for ~7 years.We need POE for a VOIP phone system, and 10gb uplinks back to the core. We want to have the ability to go POE+ in the future.
We were quoted from our vendor for:WS-C3850-48P-S with 2x715w Power supplies. It looks like the data sheet says that to get POE+ you need 2x1100w or 1x1100w & 1x715w. Do we need to step up to the WS-C3850-48PF-S?
Cisco WAN :: Password Recovery On A Catalyst 3850 Switch
May 23, 2013I'm trying to do password recovery on a Catalyst 3850 switch..I've read the section in this: url...where it says that I need to have physical access to the switch (I do), and that I reset the password if I issue a break command and interrupt the boot procedure. I've tried to do that... it gives me the "switch:" prompt, so I think I've interrupted the boot procedure successfully, but, what do I do next?I've successfully done recoveries on Catalyst 2950s, 3550s & 3560s, but the procedure for this one, if I'm reading the link above right, sounds like it's completely different.

Mar 10, 2013I understand that Cisco *wants* the APs to be directly connected to the new 3850.I have a few questions. Unfortunately, I think I know the answers. I just want to confirm.
a. When MA/MC is enabled on the 3850, does the 3850 start intercepting *all* CAPWAP packets it sees (much like CDP)? Even non-Cisco CAPWAP packets?
b. If I have a WLC 5500 upstream from the 3850, would APs hanging off a downstream 2960 be able to register to the 5500 through the 3850 when the 3850 is NOT in MA/MC mode?
c. If I have a WLC 5500 upstream from the 3850, would APs hanging off a downstream 2960 be able to register to the 5500 through the 3850 when the 3850 IS in MA/MC mode?
What I'm afraid of is:
a. yes, yes
b. yes
c. no
From the Q&A page:Q. Does the Cisco Catalyst 3850 support indirectly connected access points?A. No. The Cisco Catalyst 3850 switch will always terminate the CAPWAP tunnel locally. Pass-through mode or indirectly connected access point is not supported at this time.
Cisco Switching/Routing :: N5K-C5548UP-FA - Switching / Routing Capacity?

How can I estimate it? What else should I consider?

Jan 11, 2012we've had an issue with our network, we have 2 6509 connected with redundancy, which are connected with 2 x 4900 Switches, from which are connected to a ESX Chassis for visualization, the thing is that the ESX stopped working, and the 4900 switches, and the main core were suffering from overload, they hang on it very well, in order to stop the overload, one of the links to the ESX Chassis were disconnected from one of the 4900 switches. The CPU usage from the 4900 and the core(6509) went down below 40%, and then they started to migrate the virtual servers from the chassis to another 2 chassis that were added right after. They were actually working well, but suddenly the 6509 changed to the other supervisor after everything was OK. We were wondering what could have been the cause of this, maybe the virtual servers migrations, maybe the overload from the ESX ? We also had a few question, is there any need to reload the cores every few months as a planned task ? Because the cores have been up for more than 1 year. And also is there any kind of of tool to monitor the CPU status, or the status overall from the cores or the switches ?
View 3 Replies View RelatedCisco Switching/Routing :: 7609 For Switching / Based On LAN (VRRP / HSRP) Feature
Oct 18, 2011I am facing an isssues with 7609 for LAN switching , based on LAN (VRRP/HSRP) feature.Actually we are having ES+ cards (on 7609) and we are using multiple groups(say 350 vrrp groups) running on the router . the routers are connected as router 1>>> mux(which is working as switches)>>> router2
my questing are
1. does their will be "multicast packets" (for VRRP/HSRP group) "from backup router to Master router", when in stable state( ie when Master and backup are already chosen) , or the packet from backup to master should be unicast.I know for sure, the packet from master to back is multicast packets denstination to Multicast IP packet and To MAC address.I am not sure but I think from backup to master it should be multicast
2. what is frequency of these packets( from backup to master)
3. As i have multiper group on a single interface ( we are using q-in-q), when the connectivity from router's is broken, then does all the groups will muticast their active roll in the lan sengment "at once" or it will be in a groups say 100 groups at once, and after few ms few 100's and sone ( as is on OSPF or RIP)
we are in between troubleshooting I hope we get the ans( Actul problem we are seeing in the router's that we have 2 ports on active routers and 2 ports on standby router , but we are not seeing muticast on 1 port on standby router where as all other 3 ports are seeing multicast packets) [code]

View 3 Replies View RelatedCisco Switching/Routing :: 2921 Process Of Switching Infrastructure Of Firewalls / VPNs
Jul 4, 2012We are in the process of switching our infrastructure of our routing/firewalls/vpns over to cisco. We are switching our first location and one of the issues I'm struggling with is windows authentication pass-through for internally hosted web pages. Meaning, user inside our network has the 2921 as their default gateway, they try to access a web page that is hosted on the internal network but is secured with windows authentication. In the past, because they are logged into the domain internally, the website authenticates and loads. After switching to the Cisco, it asks for a password even though they are logged in.
Because its the web server that actually authenticates I'm not sure why the router isn't allowing that to happen, but I can't think of anything else that could be causing this behavior.

View 7 Replies View RelatedCisco Switching/Routing :: Switching Redundancy For ESXi VMHosts Scenario
May 12, 2013I have the following devices :
-1 VM Host
-2 Layer 3 switches
I would like to provide full redundancy for all vlans being used by VM Guests on the VM Host as well as the management vlan being used by the VM Host.I have created two LACP etherchannel connections on the VM Host. Each etherchannel from the host consists of 4 ports spanning a single NIC. One etherchannel connection goes to a trunked etherchannel connection on switch 1, and the other etherchannel connection goes to a trunked etherchannel connection on switch 2.Switch 1 and switch 2 have an etherchannel connection between them that carries all of the vlans in the topology.Vlan 2 is the managment vlan. Vlans 3, 4, and 5 are vlans that VM guest systems will be using for normal data traffic.
I intend to use switch 1 as the VRRP active router and spanning-tree root bridge for vlans 2 and 3.I intend to use switch 2 as the VRRP active router and spanning-tree root bridge for vlans 4 and 5.The spanning-tree configuration is using multiple spanning-tree with two instances. Instance 1 has vlans 2 and 3 associated and Instance 2 has vlans 4 and 5 associated. I would like to have this topology be fault tolerant to the point where if one of the etherchannel links between the host and one of the switches goes down, (for example, if switch 1 was powered off) traffic will be automatically redirected through the other functional link. I believe that my VRRP configuration would allow for a fairly quick failover of layer 3 services, but I am not certain that my design will be functional at a layer 2 level.
What I am uncertain about is how spanning-tree will converge. I am assuming that the virtual switch on the VM host will not be forwarding any BPDUs being sent by either switch. Would either of the links connecting to the host be considered a redundant link by either switch?Would the link between switch 2 and the host be inactive for all vlans in MST instance 1 during normal operation?Conversely, would the link between switch 1 and the host be inactive for all vlans in MST instance 2 during normal operation? Would all links remain active for ALL vlans? Would this mean that some traffic may travel through switch 2 to reach switch 1 instead of going directly to switch 1?

Mar 21, 2012I got Two Distribution Switches of Cisco 3750G. Each Distribution have two 3750G switches stacked. I also have one Cisco 3750V2 Access Switch connected to both Distribution. When I am checking for redundancy, I can only get redundancy test pass for one link not atall for other. If I have a link up with Distribution 1 only then its fine; but disappointment with Distribution 2 link. I can see that the switch priorities of Dist 2 is not correct ie. Master's priority is 10 and Member's is 15.
My question is that due to misconfigured priorities on Distribution 2 stack switches I am failing with redundancy if ONLY Dist 2 is up and Dist 1 is down.
