We 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?
I am trying to decipher the differences between the two models of the 1921 router. One has an IP Base IOS and the other has a Security IOS. I have an ASA so I don't think I need all the Security IOS bells and whistles on an internal router. Although, does the IP Base IOS allow for trunking and sub interfaces? I definitely need that and on CDW's website it says that the 1921-Sec/K9 w/ Security IOS includes 802.1Q and that spec is not listed on the 1921/K9 IP Base IOS model.

View 2 Replies View RelatedWe are considering order the AP541N for our network. A few questions...
1). Are there multiple models of the AP541N? or just one cisco part number?
2). I am assuming the basic antenna comes with it. If this is something that I need to buy seperate.
3). Are there part numbers for the POE injector? Need to know part numbers on the AP541N and the poe injectors?
4). We would buy a couple of these and run them in cluster mode. My understanding is that I won't need a controller. Do I need to buy a certain model to use the clustering or is that available on all the AP541N?
5). Can I have this talk to active directory to authenticate users? Is that tough to do? Do I need install some kind of agent on a domain controller? I have configured the ASA to use Active Directory for authentications. Should it be any more difficult that that?

View 5 Replies View RelatedACE 4710 deployment model. We'll be doing an eval later in the year, but I'm just looking to understand the architecture.We have a stack of 3750 switches with a single VLAN (10.1.1.0/24). Connected to that stack is a pair of web servers (10.1.1.5 and 6) that we want to provide load balancing/failover for. Some of the clients are located right there on that same VLAN. Other clients may be coming from other spots in the infrastructure.It sounds like I could put a pair of 4710s connected to that stack of switches, in a single arm deployment? And then the virtual IP and the real servers would all be 10.1.1.0/24. Maybe use an etherchanel to connect each 4710 to two 3750s?

Am I correct in thinking that doing this will allow wireless clients to 'roam' seamlessly between the two APs?
APs must be directly connected to the 3850 for it to work in MA or MC mode. But if we add some switches and configure it to work transparently (without CDP/ VLAN tagging /LDP ) ? Do you think this is really not possible to make it? What impact CAPWAP tunnel gets from this transparent switch ?

so what exactly this mean the two controllers are L2/L3 adjacent to each other , what is the different between them.

I'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.

View 8 Replies View RelatedI 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.
With 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?
I 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.
I'm adding some additional AP's (3502s) to an environment that is all 1131AG AP's. The DHCP is configured for DHCP option 43 for remote sites for layer 3 discovery. Since only one AP mode can use option 43, I've added a DNS entry for cisco-lwapp-controller in my local domain.My assumption here is that the new 3502's will be able to use DNS for discovery, while any additional 1131AG would continue to use DHCP option 43. will this work in a mixed environment?The new AP briefly showed up on my controller, but then disappeared. The LED is cycling red, green, off - indicating it is still in the discovery process. Could I effectively remove the option 43 in DHCP and have all AP's use DNS? Is this as reliable as option 43? What is the best practice for discovery?
View 6 Replies View RelatedWe 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...
I 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.
I 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 RelatedI 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.
Does Ethernet mean a cable is needed?
Does WiFi mean no cable is needed?
