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 :: Changing Native Vlan On 3550 Switch

Dec 22, 2012

I am having trouble after creating a management vlan (99) on a 3550 switch.I have configured the vlan (99) and given it an IP (192.168.1.100) and a default gateway (my router address - 192.168.1.99).I can ping to the switch from a PC and vice versa. The management VLAN IP is fine but now I cannot ping to the router from either the PC or the switch.It seems that just by adding VLAN 99 with it's own IP address has now prevented pings from the switch/ PC to the router ?Due to the fact that I have created a new switch management VLAN with an IP, does this mean I have set up the router as a 'router on a stick' scenario ?

Cisco Switching/Routing :: Determine VLAN Tagging On A 3550?

Jun 13, 2013

We are trying to replace the CSS between our firewall and DMZ with a BigIP.  Among it's other functions, it will act as the router between the firewall and the DMZ. To make this work, I need to assign vlan tags values for the vlans I create on the BigIP box and these must match the tags on the cisco switches (3550's)  How do I find this information on the switch?

Cisco Switching/Routing :: Manipulating VLAN Quickly On Catalyst 3550

Dec 12, 2011

I am attempting to create a mass upgrade server for some of our more standardized equipment since our vender cannot upgrade them pre-shipping for us, we've got to do them on our own. This means using a terribly organized wizard written in what appears to be Java...
 
I have an aversion to Windows and felt that I could accomplish the same thing using expect scripts and a Gentoo Linux server; now all I need is to set my Cisco 3550 (c3550-ipservicesk9-mz.122-44.SE6.bin) to have each port on it's own VLAN, except for fa0/1 which will be a trunk port to communicate with all ports as well as the server.

Cisco Switching/Routing :: SG200 / 3550 - Creating VLAN And Isolating PC On Network

Feb 12, 2013

I was given a task of creating a vlan and isolating one pc to access an internal website (192.168.90.15) on a specific port (port 8080)The pc is connected in the following manner:

PC--> HP Switch --> Cisco Small Business SG200 switch --> 3550 Catalyst 1, 3550 Catalyst 2 and 3550 Catalyst 3.

I have created a vlan 110 on the Main 3550 Catalyst switch and successfully added the pc to that vlan.However, that PC must be able to access the internet and an internal website on port 8080.I have placed an access-list on the main 3550 catalyst switch which is connected to our router as below:

Client ip address: 192.168.100.2
VLAN 110: 192.168.100.3
 
access-list 110 permit tcp host 192.168.100.2 host 192.168.90.15 eq 8080access-list 110 permit icmp host 192.168.100.2 anyaccess-list 110 deny ip 192.168.100.0 0.0.0.255 ? I was unable to access the webserver even after many attempts.

Cisco Switching/Routing :: GLC-GE-100FX - Connection To 3550 Switch Over MMF

May 21, 2012

i have an OM1 MMF fiber run between two switches, the first being a 3750 and the second being a 3550.
 
The link currently exceeds the maximum distance for OM1 @ 1000Mb/s (220m) so i would like to downgrade the link to 100FX using the necessary SFP's/GBIC's to extend the maximum distance to 550m and run the link @ 100Mb/s.
 
I have the part code for the 100FX SFP to install in the 3750 (GLC-GE-100FX) but cant find a 100FX GBIC for the 3550, can I use a 1000SX GBIC (WS-G5484) for the 3550 at one end and the 100FX SFP at the other? Any success with this configuration over MMF?

Cisco Switching/Routing :: Port Unreachable Messages On 3550 Switch?

Jan 24, 2012

While working at a client site today, I was troubleshooting some ICMP connectivity for a network we have created.I turned on 'debug ip icmp" on the 3550 switch int he middle, and was inundated with the following debug output:
 
Jan 25 11:01:14.641: ICMP: dst (172.16.1.7) port unreachable rcv from 172.16.1.5
Jan 25 11:01:14.641: ICMP: dst (172.16.1.7) port unreachable rcv from 172.16.1.5
Jan 25 11:01:14.641: ICMP: dst (172.16.1.7) port unreachable rcv from 172.16.1.5
Jan 25 11:01:14.641: ICMP: dst (172.16.1.7) port unreachable rcv from 172.16.1.5

[code]....
 
This output fires several times a second, and based on how often it is firing, I am curious if it may be a culprit with respect to the fact that the client has indicated that they have some slow internet.Should the next step be to look at the workstation at 172.16.1.5?

Cisco Switching/Routing :: Catalyst 3550 Switch - Dynamic QoS Setup

Mar 28, 2012

I live in a condo building that uses 3 Cisco Catalyst 3550 switches connected to a Comcast router with 100 Mbps download. Currently we regulate bandwidth by providing each user with 3 Mbps download. Even if only two people are active they still only get 3 Mbps download. I would like to set it up so if two people are using they each get 50 Mbps; a sort of 'dynamic qos. Is this possible with these switches? Would we have to purchase a Cisco router in order to provide this feature?

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 :: 3550 - Copy IOS To Switch In ROMmon Mode?

Jan 24, 2012

I have a 3550 switch that was replaced at a remote site with no IOS. This is a switch not a router so tftpdnld does not work.
 
[Code]...
 
The problem is the switches interface never comes up so try to connect to the tftp server. I read on google it can't be done on a switch to copy from tftp to flash in rommon mode on a switch and to use XMODEM. My problem is I do not have access to it, I ssh into a 3640 which is an access server for all devices and that is how I have console to it, how to use XMODEM over ssh.
 
But I'm fairly certain that there has to be a way to just copy it from tftp? I have a 3550 local and when I put it in rommon mode it stops the port check at port, port 1 goes from green when you plug it in to off then port 2 changes to amber and the rest green. So just by the look of this I would believe tftp would work; you just need to use port 1.

Cisco Switching/Routing :: 3550 Switch - Software Forced Crash Exception

Feb 7, 2013

Our switch had a little crash-fest this morning at 2:30 AM. I did find a web page about diagnosing Software Forced Crash Exceptions, but it did not look like ours was one of the more easily-identifiable ones.
 
It may be worth noting that we've only used this switch for about a month, everything seemed fine until now. When we got the switch it did not have any GigE modules, and this week we put 2 into it and have been using them for 2 servers.
 
It looks like the switch was crashing repeatedly over a period of 20 minutes, and then it stopped and normalized. In the logs of the router that this switch uplinks into, we could see the ethernet port flapping during the time that the switch wasn't reachable.
 
Here's the Show Stack on the switch:

Cisco Switching/Routing :: 3550 - Export Mac Address From Switch To Local Machine?

Jan 8, 2013

I am working on Cisco 3550 switch on a certain requirement. I have got an access point connected to the switch and few mobile phones connected to the access point. I get the list of mac addresses connected to the switch ( Both access point's mac address & the clients addresses) by "show mac-address table dynamic" command. However, i am unable/confused to get the output of the following scenarios:
 
1. I would require to export the mac address from the switch to the local machine in any format (May be by using an SNMP tool, if available) so that the same needs to be used in my C# for development.What would be the way for the same ?
 
2. The mac address in the mac address table doesn't get updated dynamically. (Eg Scenario: A wifi client gets connected to an access point which inturn is connected to the switch, the mac address of the client shows up in the switch table. However if the client is disconnected, the client's mac address would still be displayed in the switch table )

Cisco Switching/Routing :: Inter-VLan Routing On Catalyst 3750 Switch

Dec 17, 2011

I have been looking into this for a while and I can't seem to figure out why my 2nd vlan is not able to connect properly to the net.
 
My switch has 12 ports where my devices connects directly, they are all on Vlan 1 and they all work perfectly. on Port 12 I have a dlink router that is connected to a cable modem. the dlink router has an Ip address of 192.168.0.20
 
I created a second vlan (vlan2) and enabled dhcp relay on it. then I assigned port 9 on the switch to  (vlan2)my laptop which is connected to port 9 seems to get an ip address fine and able to ping only some devices on my network (vlan1) and is not able to go out to the internet.  I think it has to do with the routes.

Cisco Switching/Routing :: Inter-VLAN Routing Using 877 And SG300-10 Switch

Feb 5, 2012

I recently set up a small photography business and am trying to get a Cisco 877 and Cisco SG300-10 switch to talk to each other.
 
What I want is for the Cisco 877 to handle the internet and the SG300-10 to handle the local network,
 
I have set up 2 vlans in trunk mode on the switch and want vlan2 to manage local traffic and vlan3 to handle the internet.
 
I have got the 877 connecting to the internet what I dont have, traffic going to vlan2 on the switch from the 877
 
Look at the running configs for the switch and the router and tell me how to get the vlan on the router to pass traffic to the switch. In a nutshell I am inserting the internet into the switch but am not sure how to progress. I have the c870-advipservicesk9 image file on the router.

Cisco Switching/Routing :: 3560 VLAN Routing Between Switch And Router

May 8, 2012

I have an environment of 3 X 3560G of which I have 1st switch-CORE(f0/10) connecting to the VPN router(CE) interface-f0/0. Remaining 2 Cisco 3560's(Access) are connected to Gi0/1 and Gi0/2 on the 1st switch-CORE via gi0/1 . On all three switches I have created multiple VLANs and assigned ports to these VLAN. The switch to switch connection is trunk allowing all VLANs created on all these 3 switches. Now the issue is how I am going to have all these VLANs routed through single interface on the routeri-e f0/0, as all these subnets will communicating to remote site over VPN. What should be default gateway on the 2 Access switches and the CORE switch, also what static route should be on router to reach all subnets(VLANs) created on these 3 switches.
 
I have read inter-VLAN routing i-e creating sub interfaces on router but dont want to proceed with that and looking for any other way to have my VLANs talk on all three switches and then are accessible to remote site ove VPN?

Cisco Switching/Routing :: 3750 - Extending VLAN To Remote Switch That Already Has VLAN ID In Use

Jan 10, 2013

I have two networks at two sites with a dot1q trunk between the two L3 switches at both sites (no routers involved)
 
SITE A - Cisco 3750 L3 - VLAN ID 50
10.10.50.0/24
 
SITE B - Cisco 3750 L3 - VLAN ID 50
10.20.50.0/24
 
I would like to extend the SITE A VLAN to SITE B so that I can move hosts from SITE A to SITE B without needing to change their IP address but the vlan ID is already in use. Obviously the easy solution is to change the VLAN ID for one or other of the sites but both sites contain hosts that run 24/7. Is there a way to join two VLANs with different IDs together.So for example I create a new VLAN 60 at SITE B and associate it with VLAN 50 at SITE A.

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

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.

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?
