Cisco Switching/Routing :: 3550 Wireless Access Points

Feb 11, 2013

what I can do to accomplish my end goal of safe public wifi and configuration.I have 2 domain controllers (for redundancy) with a split scope for DHCP and they both serve DNS. I have VLAN 2 (management), VLAN 3 (Servers), VLAN 4 (Wired Access), VLAN 6 (Wireless Access) and VLAN 480 (Outside Wireless). I have setup INT VLANs for all of these on my main router (Cisco 3550) with the ip-helper address to the DC for all but the VLAN 480. All of this works great, and the scopes are setup just like the VLANs. (ie 192.168.2.0 (management) .3 (servers) etc.)I was wondering if there is a way to have VLAN 480 get DHCP from the cisco 3550 as a random address say, 172.16.0.0 255.255.248.0?
 
On a side note, I have seperate Wireless Access Points for the outside. (From a guy before me) I understand you can have a guest wireless setup on the newer Access Points, and trunk (cisco term) the 2 VLANs and seperate them out with Access Control Lists so they don't talk to each other, but I would rather just give the VLAN 480 it's own DHCP from the router.

Cisco Switching/Routing :: Sharing Internet Access Through A 3550 With 2 Vlans?

Apr 27, 2013

They have a locked Cisco Router which is from the ISP and its confed on a fa 0/0 interface to share Internet access on the network. The ip on that interface is 195.198.11.217 255.255.255.252 and i tried it with a PC (set my personal ip to .218 and entered their dns info (195.67.199.27) and it is working. The question is now. My friend found a 3550 laying around and since the ISP wont let them conf their router he wants to use the 3550 to create 2 vlans with internet access and without access to eachother. Vlan 10 for the desktops and Vlan 20 for the wireless (Moving on to some netgear wireless switches) How would you configure the 3550 for this to work?

Cisco Switching/Routing :: 3550 / Access List - Block One Ip Or Port

Jan 9, 2012

I have a layer 3 switch, 3550.I have several vlans on there just for playing around with. One of the vlans, has a vonage linksys box attached to it with a UK number attached. From time to time telemarketers call at 03:00 in the morning, this as I'm sure you can imagine is not much fun. The linksys box gets 192.168.3.3 as it's ip.The switch is connected to a non cisco router at 192.168.0.1
 
interface FastEthernet0/24
no switchport
ip address 192.168.0.2 255.255.255.0
 
I was thinking a time based access list would work best I have tried several variations but the phone still rings. I have tried access-list 1 deny host 192.168.3.3 permit ..... and more extensive lists but the phone still rings. I have not applied the time-range yet, so that's not the problem.I have applied the list to the vlan interface and to fa0/24 but it's not working.

Cisco Switching/Routing :: Internet Access For 3550 Switch VLANs?

Feb 22, 2012

I have a small cisco switch cluster (seven different 2924, 3524cisco switches) with 3550 as a cluster control which does all the inter vlan routing that works fine.
 
This cluster is in semi production PBX interop testing lab. This is a closed network without internet access and not connected to our corporate network.However now I have to add this capability so some equipment in the lab can get Microsoft updates over the internet.
 
I've created a port on a 3550 (fa0/19) and connected it to another network that has internet access. It picked an ip address and when I'm logged in to the 3550 I can ping hosts on the outside network. However I can't ping any hosts on that network from any hosts that are connected to my vlans.I've tried a few different things, but still can't make it to work.
 
Here is a short version of my 3550 configuration:

!
version 12.2
no service pad
service timestamps debug uptime
service timestamps log datetime
no service password-encryption

Cisco Switching/Routing :: 2975 Not Handing Out PoE Power To Phones And Access Points At Random Times

Oct 22, 2012

We currently have around 150 2975 switches and have had problems with it them not handing out PoE power to the cisco phones and access points at random times.  There is plenty of power left for the switch to use.  We have at least 15 that will be running fine for about a week and then all of the devices that use PoE power will shut off and will not come back on until we reload the switch.  If you console in there aren't any messages that pop up and if you look at the port it just shows on connected or will show IeeePD in the power inline.  We have contacted Cisco TAC and they just RMA them.

I have multiple cisco 1130ag access point at one of my clients villa. The issue I am facing is when moving throughout the buildingthe laptop and smartphones will not switch between AP’s unless it loses its connection with its existing AP then it will see the other AP that is closer and connect to it.
 
For example, I start at one end of the building where it connects to AP#1 , if I then slowly go to another section of the villa, it it will not switch over to AP#2 until the signal is lost from AP1
 
I have following settings
 
AP's are Cisco 1130AG

Cisco Switching/Routing :: 3550 / Routing Protocol Neighbor Between SVI And Routed Port?

Apr 18, 2012

I have a collapsed core design with routed ports between all components. Access layer switches, data center switches, core/aggregation. All routed (no spanning-tree at all).Now...I have to add an IBM BladeCenter with a BNT layer 3 switch to my topology. However, those nasties don't seem to support routed ports.How can I have a routed port on my cisco switch and a standard access port on the BNT and still establish an adjacency with an SVI? I am running OSPF, but I am labbing this in my home lab with 2 x 3550s and EIGRP.
 
On SW2:

Cisco Switching/Routing :: 3550 - IP Routing In L3 Capable Switches?

Apr 11, 2012

Is L3 ip routing on by default in 3550s?  If so is the "ip routing" command visible in the config file?  If no - I assume that one would enable L3 routing with that config command.In general terms are there any IOS devices where ip routing is enabled and one would not see the "ip routing" command in config.  I.E. if that command is not visible in the config could you assume there is no L3 capablity in that device?

Cisco Switching/Routing :: Configure Routing Between 2800 And 3550

Sep 18, 2012

The layer 2 switches are connected to layer 3 Switch via trunks, and routing between layer 2 switch ports with configured SVI's on 3550. All working fine. Now I'm trying to configure routing between 2800 and 3550, I tried connecting both Straight Throught and Crossover cables to the 2800 Fa0/0 and Fa0/1 ports as well as the switchports on 3550
 
No switchport commands are configured however, the lights do not go on for both straight through or crossover cables. I tried connecting 1750 routers but same result. My goal is to have all the VLANS routed to the internet with configuring NAT translation the router.

Cisco Switching/Routing :: VLan Routing Same Switch 3550-12T?

Mar 10, 2013

I'm having some problems setting up vlans to talk to each other on a 3550-12T switch. Its quite a simple setup I have, but I need to split my network up.
 
Currently I have a network of 192.168.25.0 255.255.255.0 I want to create a new vlan network of 192.168.30.0 255.255.255.0 So I have configured my vlan1 (default vlan) to have an ip of 192.168.25.250 for getting to the management page
 
I have created a vlan2 of 192.168.30.1 255.255.255.0 ?I have a port 10 linked to one of my 3560G's?In port 9 which is on vlan2 I have my pc plugged in with a static ip of 192.168.30.50 from the router I can ping any device on 192.168.25.x.
 
I can not ping 192.168.30.1 (which is my vlan2) nor can i ping the PC.
 
I have enabled ip routing  But I dont have a default route, this is becase we don't have a router on the network.

Cisco Switching/Routing :: 2600 / 3550 - InterVLan Routing

Dec 2, 2011

I've been working with these two Cisco devices in my home off and on for several months now but I just can't take it anymore, I'm about to throw them away and go back to Linksys router.
 
I have a Cisco 2600 Router with only one Ethernet card in it so I have to trunk from my 3550 Switch to that device.  I'd like to have my ISP and all users plug into switch and all trunk back to the router's sub interfaces. Currently, I have started over...again, and am unable to simply get the router and switch to ping each other if I put sub-interfaces on the router.  See my configs:
 
2600 ROUTER:
Router#sho run
Building configuration...
Current configuration : 555 bytes
[code]......

3550 SWITCH:
Switch#sho run
Building configuration...
Current configuration : 2302 bytes
!
version 12.2
[code]..........
 
Port F0/24 is in VLAN 1, as are all ports but Port F0/1 which is my desktop PC. I mocked it up in Packet Tracer and it works just fine.  This is just a simple setup and I'm making sure I can ping between switch and router before I move to each next step.

Cisco Switching/Routing :: 3550 QOS For Voice Over IP

Oct 25, 2011

We'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?

Cisco Switching/Routing :: QOS Between 4510 And 3550?

I am having issues working on my QOS between 4510 and 3550 switch connecting on layer 3 through a service provider. I have class maps and policy map setup on both sides and then policy map attached to interfaces however i dont see any traffic matching in policy map on 3550 switch, i do see some traffic matching on 4510 but the speed with which its increasing has my doubts about it. When i make voip calls ( VOIP switches are sitting behind 3550 and are mainly 3550 pwr 24 port switches with phone ports configured for auto qos voip cisco-phone and trusting cos) i rarely see the RTP matching in class under policy map.

Cisco Switching/Routing :: Upgrading From Cat 3550 To 3750?

Aug 30, 2012

we 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?

Cisco Switching/Routing :: Policy Map On 3550 Not Working?

Sep 27, 2012

We 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.
 
!
class-map match-all REALTIME
match access-group name REALTIME

confirm whether the Catalyst 3550 with IOS Rel. 12.2(44)SE is compliant with POE IEEE 802.3af?   I see some conflicting informaiton on Cisco's web site. Before Release 12.1(22)EA2, Catalyst 3550 PoE-capable switches (without intelligent power management support) caused high-power powered devices that supported intelligent power management to operate in low-power mode. Devices in low-power mode are not fully functional.
 
IEEE 802.3af—The major features of this standard are powered-device discovery, power administration, disconnect detection, and optional powered-device power classification. For more information, see the standard.

Cisco Switching/Routing :: 3550 - Not Getting Internet As Well As Ping

Feb 19, 2012

We had re-arranged and purchased new public ips and changed with new modem. Following is the new network setup diag
  
I have started the configuration, but stucks at a point. Current configurations setup and ip assigment is as follows
 
ISP modem/router(192.168.3.254)-->(192.168.3.1)1811W Router(192.168.2.254)-->(192.168.2.1)3550(interface vlan 10 - 10.0.1.254, interface vlan 192 - 192.168.1.254)--trunk-->2950

1)Configured 3550 as layer 3 switch and create a default route to  192.168.2.254

2) Configured 2 static routes(for 2 vlan range traffic) and one default route to 192.168.3.254

3) ip pass through is not configured yet, still the public ip is configured at the isp router 
 
1811 static route configs
------------------------------------
Ip route 0.0.0.0 0.0.0.0 192.168.3.254
Ip route 192.168.1.0 255.255.255.0 192.168.2.1
Ip route 10.0.1.0 255.255.255.0 192.168.2.1 
3550 static route config
-------------------------------------- 
Ip route 0.0.0.0 0.0.0.0 192.168.2.254
 
Testing results 1)All  lan communications are working fine(inter vlan also), ping to all  servers from router is getting and ping to outside public ips are  getting from router,but not getting ping from switch 3550 to 192.168.3.254  and any of the public ips(internet).
