Cisco Switching/Routing :: Created Load Balancing Between Two Catalyst 3550 On Couple Of Vlans
Feb 24, 2012I am testing on lab equipment (2 Catalyst 3550 and 1 Catalyst 3560) HSRP version 1 and 2.I successfully created a load balancing between the two Catalyst 3550 on a couple of vlans (11 and 12) on ver 1
now, just adding the command "standby xx version 2" my hosts on the 2 vlans are completely unable to ping the virtual IP def. gw on debugging i checked that msgs are exchangedthe two cat 3550 are seeing each other on HSRP (active / standby roles)the real ip addresses are pingable rebooted the swiches (just as a last resort try)deleted arp chache on hostsremoved the auth on hsrp all of this no effect.
i also tried to modify the priority on the cat 3560 (before he was on both vlans in standby) to make it the active one and with the same config it worked flawlessly.
My only idea is that there is a bug on CATs 3550 (IOS: c3550-ipservicesk9-mz.122-55.SE4.bin) [code]

Nov 28, 2012We have approximately 150 1142 LWAPP's deployed in our facility. Recently we started getting complaints about speed issues (90% are using G 10% N). Upon investigating we found that the speeds are fluctuating rapidly. Everything from 54Mbps down to 1Mbps and back up again. I've confirmed that this will happen while standing next to an AP (and confirming connectivity to it), however I cannot find anything wrong or anything that has changed with our configuration. We are a large facility and it is happening all over the campus, so I'm fairly certain it isn't any type of 'normal' interference.

Jun 17, 2012Purchased my dell XPS-17 laptop five days ago. When i connect to Wire less and test my download speed it keeps varying ranging from 1Mbps to 40 Mbps. Where the Wire connecting gives a constant speed of 58-62 Mbps. Checked with my Internet service provider. The analysed the issue, logged into my computer in safe mode and the wireless was giving a speed around 55-60 Mbps consistently. They say some application is causing the speed fluctuation. Can you suggest if any of the Dell Pre installed apps can cause this. I have just installed gtalk/yahoo messenger and Winamp from my side , and they are not in the startup menu and not even launched when i test the speed.

Feb 26, 2012My new e3200 setup just fine with Cisco Connect. I have consistently good speeds with a direct ethernet connection, but the wireless speeds fluctuate widely. When I power cycle the router, I'll have perfect speeds for a few minutes and then it'll slow to a crawl (approx 0.5Mbps). Then for no apparent reason, it will speed back up to normal, and then back down to a crawl. I'm using the latest firmware and have allowed Cisco Connect to manage the router so far.This is actually my 2nd router, as Tech Support told me when I experienced this with the first router that it was defective, but I'm seeing the same problem with the 2nd router, so I know something isn't quite right.

Mar 24, 2013I have a Catalyst 3550 switch and 2610XM router connected with an ethernet cable. Currently I cannot get the port on the switch to open (lights are dark.) I run 'no shut' on the port (#13) but nothing happens. If I unplug the cable to the cisco router and plug in a Netgear router (that leads to the internet) into the same port, the port flickers amber for a while, then flickers green from then on.) I switched the cables, both work fine when connected between the switch and the Netgear router.
This was working at one point a couple of days ago. I had the Netgear router plugged into another port on the switch and could ping from the cisco router through the switch to the Netgear router. I thought I had figured things out, but a reboot disavailed me of that notion. (I know, I guess I didn't save my configuration, but I obviously still need to understand more, so its better that I didn't.) (I guess.)
When the problem is occuring, the below is what I am seeing on the two devices.

May 30, 2011I have 802.1x configured on a 3550 switch with ACS 5.1 acting as the AAA policy server.
My problem is this. When my computer boots up, ACS authenticates the machine to AD slapping me in a guest VLAN with limited access to the network. Once I login though, I reauthenticate to AD via ACS which then puts me into an employee VLAN but my IP address doesn't refresh automatically. I have to run ipconfig /renew to get my IP in the correct VLAN or write a logon script that does the same thing everytime I log in.
Is there anyway for this to be done automatically outside of writing a logon script?

3550 Find At Least Two More Switches
Jan 22, 2012I finished the CCNA and CCNP classes last year but due to wife/school/excuse I did'nt have time to buckle down and study for the tests. So since time is flying buy and I got my new desk set up I figured I would set my lab up and get cracking.
On top I have a a Pix 506 and a 1900 switch. I need to find at least two more switches, hopefully 3550's or something close.Then I have 5 2600's with an assortment of cards, but I would like to replace most of them to either WIC 2T or HWIC 2FE's.
Not shown on the bottom are 2 2500's that will be configured as Frame Relay switches. I have a 3600 sitting on my bench in the shop and I was hoping to get something I could configure as a terminal server as well. I have GNS3 on my lab box and was planning on getting another network card and tying it into the hardware lab.

Cisco Switching/Routing :: 3550 QOS For Voice Over IP
Oct 25, 2011We're looking at implementing a new phone system which will use voice over ip. Currently we have a mixture of Cisco 3750 and Cisco 3550 switches which don't support power over ethernet. Its been suggested we could continue using the current switches and power the new phones using power adapters.
Int terms of implementing qos (we don't have any at the moment) for the voice will a Cisco 3550 be OK and will having a mixture of different models using 3550 and 3750 pose any challenges with the qos policy for the voice. I believe there are differences in that the Cisco 3550 doesn't support srr-queues but having little experience with qos I'm not sure what impact this will have if any?

View 1 Replies View RelatedCisco :: 3550 Vlan Settings With Dlink 3200AP?
Dec 5, 2012I currently own 3 Dlink DWL-3200AP that are setup on MultiSSiD with Vlans 1 and 2. I just picked up 3 Cisco 3550 layer 3 switches. I also own a Cisco ASA 5505 (acting as a router) which is connected to the internet. The 3 switches are connected using the GiBi connectors to each other. They are across the campus from each other, one switch is in the room of the router. Each switch has 1 of the Access points on them.
What I am trying to do is setup the switches to take SSiD 1(Vlan1) to have access for the entire network and have SSiD 2(Vlan2) just hit the router for internet.
I have all static IP's setup on the SSiD 1(Vlan1) connections, and I want to have a DCHP server for the SSid 2(Vlan2).I setup in the Cisco Network Assistant, for the 3550's to have VLAN 1 be port 48 and VLan 2 be port 47 going to the router.
What is currently happening is that if I connect to the SSiD1(Vlan1) I can access all of the switches and the router no problem. When I connect to SSiD2(Vlan2) I cannot connect to anything, ping or otherwise. I figure it might be something in the Access Point but at this point I am hitting my head on a wall trying to figure out what is going on.
Cisco :: Can't Get My 3550 To Save 115500 Baud Rate
Jan 27, 2013I've configured all my devices in the lab to use 115200 baud rate, so I can speed things up a little at the console. For whatever reason, I can't get my 3550 to save the 115500 baud rate. I power on the switch, hold the mode button, at the switch: prompt I type 'set BAUD 115200' followed by a reset. I power the cycle the switch once more, yet it still holds at 9600. I did the same process on my 3560's and it worked like a charm.

Aug 30, 2012we have two core swiches 6506 and around 55 cat 3550 switches. currently we are on the process of replacing the cat 3550 switches to 3750 switches.We need 10/1000/1000 speed, ip base image with upgrade options. Our up links from cat 3550s(sfps) are single mode and dual mode fiber mode with 1 gbps ports on core switch.
At present we are not upgrading to 10 gb modules on core. Spread over 15 floors each floor needs 2 up links(single mode , and dual mode). since cat 3750 sfps are smaller in size existing gibics cannot be used. Looking for the best option of cat 3750 switches with 1 gb up links which can be upgraded to 10 gb later when we replace the modle on core. Requirements:
1- Cat 3750 switches 55 in no with sfps for 1 gb up link (dual mode fiber and single mode fiber)
2- stacking option
3- 10/100/1000 speed
4- ip base image upgradable to ip service image
5- ipv6 compatibaility. Network is spread over 15 floors so from each floor we need two sfp up links 1 gbps using dual mode and single mode
-6-Should be upgradable to 10 gb in future when we upgrade the core modules
Or is it better to go for 10 gb module in core as well as edge switches ? if so what should be the modules?

Sep 27, 2012We have a metro Ethernet service, basically our WAN connection, that we use to connect 4 sites. This MOE service has a CIR of 200 Mbps, connected to a port on a 3550-12T running Version 12.1(22)EA5 at 1000 Mbps. We are exceeding our CIR at times during the day for short bursts which is causing the MOE switch to drop packets, which I suspect I am seeing manifest itself in some choppy VoIP conversations and dropped ICMP packets from our network monitoring software. I implemented policy maps to apply an outbound service policy to the interface connected to the MOE service, but I am not seeing any matches to the access lists or the service policy. I’m not sure if I am missing something or perhaps the IOS is not capable?
Below is the config for the service policy and some command output. Notice that there are hits on a statndard access list that is used for other purposes, but the extended access lists used for the class maps have no matches.
