I have read in some documents that we should have one Ap for more or less 50 clients. But i also read for example in ap 2600 specs that it support maximum 200 connections per radio.So for example in a conference room (10mx5meter) for 150 users in theory can i have just on Ap2600 for web surfing or i should have 3?
View 14 RepliesI have a customer that in the past has been using 6506E chassis with Sup32 and the WS-X6196-21AF cards for their closet.With the End of Sale of this combination and the announced End of Sale of the Sup720-3B announced, this kind of pushes the configuration to a Sup 2T.BUT the SUP 2T does not support these low speed high density cards.
Is there a card coming that will address need? Customer generally has had dual sup32's and 3 to 4 cards of the 96port AF.They stock spares besides haveing smartnet on the boxes or moving to a different platform like the 4510R+ or stacks of switches will mess them up.

View 2 Replies View RelatedWe're looking for Cisco switches with the following attributes to serve as the core switches in a production network:1U (or close), fixed config20 or more 1GbE copper ports4 or more 1/10GbE fiber ports (SFP+)Not ridiculously expensive So far the closest fit we've found for these requirements is the SG500X-24. However, since the SG500X-24 is a "small business" switch we're concerned that the reliability may not be up to the levels of Cisco's enterprise switches, the support level may not be sufficient, the 12MB packet buffer may not be enough to support wire-speed operation (or efficient communication between hosts on 1GbE and 10GbE ports), and so on. But in looking through Cisco's entire current switch line (a daunting task...) this seems to be the switch that best fits the specifications above. So, some more appropriate switch that fits the listed requirements?s why the SG500X-24 would be a poor choice for a production network? Have you had positive experiences with using the SG500X-24 as a mission-critical switch?
View 3 Replies View RelatedI have 3560's in my current environment, operating in the core/distro/access layers. The switches are in a star configuration, performs only layer 2 switching, and utilizes copper (no plans on moving to fiber).
With a fairly limited budget, I've been contemplating on upgrading the central node to a stacked 3750X to eliminate that single point of failure, and trunk the rest of the 3560's to the stacked switch. I wanted to be sure that the 3750X switches will be right for my environment (90-100 hosts), and if what I explained above is a good solution.
I'm also looking like to upgrade 6-7 of my servers (and SAN) with 10GB network cards. Do the ports on the 3750X have port densities capable of 10GB? If not, what switches provide that capability?

I currently work for an enterprise that want to deploy wireless network (6AP for now) and I'm the one who will manage and install it.I had initially planed to deploy Ubiquiti network because I've heard lot of good thing about them. But they did not wait me and bought (crappy?) HP access point (MSM410)
What do you think about HP wireless network ? They did not yet buy the access point controller and I'm not sure they want to buy one.I can't find any review on the HP solutions it looks like no one is using it.
Do you recommend me to continue with the HP solution and buy a HP controller or go with Ubiquiti and rebuy the access points (no so much expensive in comparison with the price of the HP controller alone)

View 2 Replies View RelatedWe are starting to greatly increase our access point density throughout our floors and I am wondering if we are using the correct channel assignments. We are using LAP 1140's and 3500's. We have some locations that have have anywhere from 4 to 9 floors in one location. These are consecutive floors that have 8 to 11 APs per floor. There are also other businesses in these buildings that use wireless as well. We use 802.11a/n and 802.11b/g/n. Right now the channels are set to the default, (36, 40, 44, 48, 52, 56, 60, 64, 149, 153, 157, 161 for 802.11a) and (1, 6, 11 for 802.11b/g/n). I was wondering that since we are increasing our density whether we should enable other 802.11b/g/n channels outside of 1,6,11. I know the other channels can overlap but with correct placement I am wondering if it would improve our wireless coverage since we wouldn't have 8 to 11 APs fighting for only 3 channels. Any experience with enabling other 802.11b/g/n channels?
View 11 Replies View RelatedI want to install a pair of 5508 to manage the whole wireless solution and I have a few questions regarding deployment, Please refer to the topology. The management and ap manager interfaces are conifgured with the same ip address range and thus the same vlan which is 10.160.254.X/24 also all the APs(1,2,3) in that building have the same IP address range for management which will be manually conifgured. The AP's (4 and 5) on the other building have another range of IP address for management and here is the first question. Will the AP's 4 and 5 join the WLC if I manually configure them to point to it? I know I can group interfaces and use them with the same SSID BUT the WLAN vlan in both sides are different and are separated by a router and hence the next question: Can this be done even if they are separated? and if I can, how is this possible, should I configure a dynamic interface in the WLC with an IP of that network even if it doesn't exists on that side? I'm kind of confused with this.

Q: If i m going to do a Bonjour Gateway deployment, do i still need the vlan select feature on the wism's or is enabling multicast enough?
Details of the Q:
I m working with WISM s and WISM2;s, 1130 and 3602 ap;s. Cores are 6509-E's.
i m going to implement a Bonjour gateway (which is an Aerohive ap, no wifi enabled, its just a Bonjour gateway)
This ap is connected with a trunk port (to a 6509-E) and has the wifi client vlans on the trunk as allowed vlans. It also has an allowed vlan for AppleTV;s which will be wired devices.
The Aerohive gateway gets an ip address in every wifi subnet, so far so good.
I was thinking that if i enable multicast :
- globally on the wisms, with mcast-mcast distribution
- on the SVI's for the wifi client vlans
- on te SVI's of the vlans for cisco aps
- on the SVI for AppleTV
- SVI for wism management
- SVI for the Bonjour gateway
then do i still need vlan select? Maybe a stupid question, but i m not sure how to interpret some things in this document.

View 2 Replies View RelatedI am busy setting up a wireless backhaul.. I have the bridge setup using 2 x 3602's ( Root / mesh) configuration. The bridge is self is up. The main idea is to get older autonomous access point (1231) connected to the ethernet and pull that back in to a temporary building. I have groupped the bridge to only have one SSID on it.
The switch port on the pwr inj4 is currently connected to a laptop - Ethernet Bridging is enabled on the mesh port. Now the laptop does get an ip form the dhcp server. This is where my issue comes in. I can ping the mesh ap's IP address, but not past it.
My client would like to have a wireless deployment between several differented offices in the city. There is connectivity between the different sites...but my main issue is, is this option really feasible. I was thinking of a centralized WLC like the 2504 coz of price + 36 APs, 2 at each site. The main worry is the network setup considering the fact that the APs have to communicate with the WLC so unpredictable network issues i believe will have a very huge impact.

View 1 Replies View RelatedToday I've received reports of slow internet access/activity and have noticed myself that it seems a bit slow today. On the dashboard of our asa 5510 the "outside interface" traffic usage is running constantly high. It's at the top of the graph. How can I tell what is causing the spike in utilization. It usually runs at about 1500-2000 Kbps, and now it's up over 10,000.
View 6 Replies View RelatedWe installed a solution with 2 Cisco 2801, BGP multihomed failover.
1) The router which is currently getting all the traffic gets to 55% to 60% of CPU usage when handling 40 SIP/RTP streams . This equals 10Mbit up/10Mbit down and it showed around 5800 packets TX and around 5800 packets RX, with a majority of them CEF switched. As those figures are way less than the performance figures published by Cisco, we wonder if we made any mistake in setting up our router, or if we can do something to improve the router setup.
2) Does it have an impact on router performance if we increase/decrease RTP packet size, thus increasing or decreasing the pps relative to the consumed bandwidth?
3) If it is not possible to improve router configuration, we also wonder about possible replacement units for those routers. Would a 2901 do a good job? By how much would it rise the capacity? What other models would you recommend if we plan to rise the number of concurrent calls by a factor of 4 or even 8 times of what we have now (so up to 48000 pps and 80Mbit).
Here is what we tried:
- ip route-cache same-interface does not seem to improve anything
- ip flow ingress on or off makes no difference
- disabling the inbound ACL on fa0/0 seems to reduce load by 10%, although I don't understand why - a very high percentage is CPU interrupts, and ACLs are process switched, or not?
- we tried following the Cisco guide for high CPU due to high interrupts, with no success
Here are some usage statistics:
The graphs that we plot via SNMP show a propotional growth/increase of CPU and bandwidth (and thus pps) At the highest loads, we had a bit more than 55% CPU utilization with more than 50% interrupt CPU.

View 2 Replies View RelatedWe have recently deployed Cisco APs (2600 series) in our org. but we are facing alot of bandwidth/speed issues. when a single user is copying or pasting any data into the network, the speed seems ok, but when multiple-users start copying data , so the data-rate speed gets slower and slower as the users are increasing.
Can any one tell me what is the issue? Why the internal data rate speed gets shared between users? i think each user should bydefault get any specific data rate speed, but that is what not happening on our end.
I have a couple of 2600 APs (external antenna) which are getting PoE from my switch but no ethernet. This is happening on both APs. If I connect a laptop to the (cat5e) cable I get ethernet. If i move the AP to another patch lead adjacent to my switch I get ethernet connectivity too. So, change the cable is the answer I thought, however I have exactly the same issue on both APs and each ethernet cable has been reterminated a number of times (straight through). I wonder is the 2600 AP less tolerant to the actual ethernet cable ?
I just swap the cable, however the patch leads have been run (only 15m or so) and have been replaced once - relaying again is not an easy job. It's more a case of reterminating the cable that is already there and as I've already done this a few times on each patch lead and the results are the same each time I'm thinking I'm missing something obvious.
