A router or a switch?

In my small office I use an Airport Extreme base station to provide our internet connections. Currently we have a cable connection from Comcast. Comcast has supplied a SMC8014 gateway which right now plugs into my airport to provide the wireless connection.
We are going to add wired connections throughout our office and I'm wondering what piece of equipment I need to do this because the Airport doesn't have enough ports (just 4). I prolly need about 8-10 ports for wired connections. Do I need to get a switch or router to provide the wired connections I'll be adding? Also what is a good brand or model to get? Will I just run a cable from my AEBS to this new device and then plug all my new wired connections into it?

I've used a 5 port Netgear Gigibit switch (retired, but worked fine), a pair of 5 port TrendNet Gigibit switches, and an 8 port Netgear Gigibit switch.
One of the TrendNet and the 8 port Netgear I use at home, one downstairs attached to the router, and one upstairs (cascading from the Netgear) servicing the back room office.
The other TrendNet is in my office at work servicing my PowerMac G5, my MacBook, and an HP desktop running Linux.
They have all worked fine at 10 mbits/sec, 100 mbits/sec and 1000 mbit/sec.
The only warning is that to get Gigibit transfer speeds you need to use good cables. I used a bad cable for awhile and was pulling my hair out trying to figure out why my transfer speeds were so bad

Is it possible to sort or filter the switch routes under the switching tab?

In Teststand 3.1, is it possible to filter the switch routes under the switching tab in Action Properties? Since I have a large amount of routes that have been created in Switch Executive, how can I filter out some of the routes from the "Routes to Connect" section?

The TestStand Switching does not provide any inherent filtering capabilities. You do have a couple of options, however.
(1) NI-Switch provides the ability to set up route connections in
different groups. The Switch Page in TestStand allows you to
select Routing groups as well as specific Routes. It may be
easier for you to organize your Connections as groups and choose
between different groups.
(2) The Property page also allows you to build route connection
string and use that string for your Switching actions. It
may be easier for you to build a Route string and easily change that
string rather than selecting your routes everytime from within the
TestStand window.
Good Luck!

A "Router" or a "Switch"..which is best?

I've got to connect my old G4 Powermac to the internet with a Wired connection instead of Wireless.
I plan to connect the G4 to my iMac that has a modem and is already connected to the internet.
The iMac modem has only ONE ethernet port which is already being used by the iMac.
I have been advised to use a router to connect, and another person says use a "switch" to connect.
So, I'm confused as to which one to buy. I figure, since I'm connecting to the internet "Wired" this should probably be an easy internet installation for me.
I"m ready to get this wired internet connection going as soon as I get some informatiion as to wether I should buy the "Router" or the "Switch".
Thanks.....

Those terms are often used interchangeably and may refer to the same product; it doesn't really matter which you purchase as long as it's compatible with your setup.

Trying to connect a wireless router to a switch

We have an 8 port router in the closet(linksys) with the cable connection and in our main room we have a five port 10/100 (By linksys) switch that connects to the system just fine all hardwired, and we have internet already working off of that.
We tried to connect the WRT54G wireless router to the switch because we asked at the store and they said if we had a switch already that's what we'd want. I changed the ip address on the new router to the 192.168.2.1, saved the settings and then tried to plug it into the switch. As soon as we plugged into the switch, anything else connected to the switch stopped getting internet. I also tried to just leave it at the default and same problem. I tried the 'change the IP address to 192.168.1.2 and disable DHCP server and then going into advanced and changing gateway to router and again, same problem. Regardless of what I do anytime I plug that wireless into the switch everything on the switch stops working.
How would we get both the switch and the router to work?

I assume that you want your wireless and your wired computers to all share the same network, and all connect to the Internet through your 8 port router in the closet. And the 8 port router uses the 192.168.1.x address space. --- is that all correct?
If so, disconnect the WRT54G from the rest of your network, then using a computer wired to the WRT54G, do the following:
a) set the "Local IP address" (not the "Internet Connection Type" address) to 192.168.1.2 I am assuming that you are not using this fixed adddress elsewhere in your network.
b) Leave the DHCP server set to "disabled".
c) Wire any port from your 8 port router or switch, to any numbered port on the WRT54G. Do not connect anything to the "Internet" port on the WRT54G.
Note that with this setup, your 8 port router will control your router settings (port forwarding, DHCP server, firewall, etc.). Your WRT54G will only contol your wireless settings.
If you need more help, please state the model of your 8 port router and switch.

No 'ip routing' command on switch and yet intervlan routing.

Hi,
In my companies 4500 switch I see there is intervlan routing configured for the 4 Vlans it has but I do not see any 'ip routing' command on it
to enable routing on the switch. Can a switch route even though the command isnt there?

Ran the 'show run all' command and it was there. Thought '
sh run | i ip' would display it but didn't.
Thanks for the command.
We just turned enterprise. I keep forgetting that.

RV042G (router), SG200-26 (switch) vpn vlan issue

HI,
I have a RV042G (router), SG200-26 (switch)
ISP Modem on cable have dual wan static ip
Switch have 4 Vlan
vlan1 default
vlan2 networkA
vlan3 networkB
vlan5 Modem
port (1UP,2T) management port
port 2-12 (2UP) Network A
port 13 (5UP,2T,3T) wan cable plug
port 14 (5UP,2T) go back to router wan port assign IP to network A
port 18 (5UP,3T)
port 19-26 (3UP) Network B
port25 (2UP,1T) router lan1 port connect to the switch port 25
it can separate 2 different network, if i plug a cable to port1 i can manage the switch
but if i use vpn to connect the router i wont able to ping or see the switch, but i can ping the router and all other computers are on vlan2, and vlan2 not able to go to manage the switch too or ping it
what should i change to let vpn can access to vlan1 to manage the switch, thanks

Hello Gianluca,
In order for this setup to work, you will have to have a router that supports multiple vlans. You did not mention the model of the router or if it does this so I wanted to first mention that.
I understand your setup to be as follows- Internet -> Router -> Switch 1 -> Switch 2
On each port that connects a network device you will want to set the following-
Trunk port
Vlan settings of 1U, 2T, 3T
This allows default vlan of 1 and also other vlans
On other ports (1-4 , 7-9) you want to set them as follows-
Access port
Vlan of 2U OR 3U
This puts that port into the vlan of your choice
This will be the configuration needed, but again, you must have a router that will support vlans or multiple subnets.

Home security installations: additional router vs managed switch?

I had the basic home security installed this week. I had no existing hard-wired security system. The installer attached a second router to the cable modem and went about his install and all internet traffic crawled to a 30 cps dail-up mode. The installer's opinion was "this should not happer/affect your current internet speed"; it obviously did. I had him attach the new Home router to the existing router, shut everything down, rebooted, used the iPad to complete the installation, and somehow, eventually, internet speed seemed to come back up to what it was. My current router was max'd out, re: ethernet wire connections. I would have expected the install to handle that via an unmanaged switch instead of a second modem. Questions: 1) Why a second router vs a switch? 2) If a second router is required, doesn't that require modifying settings in the routers? The second router, given what I know, creates a subnet, and the degradation of internet speed seems to have been caused by the routers competing against each other.

Xfinity Home Secure 300 System was recently installed by Xfinity Rep. He installed their Netgear WNR 1000 Router (only capable of 10/100) in FRONT of my Cisco Linksys Smart Gigabit (10/100/1000) Router. I have Extreme 150 Internet Service. Connections are: Their Netgear 10/100 Router Internet WAN Port--------to my Gigabit DOCIS 3 Telephony Modem Ethernet LAN Port Their Netgear 10/100 Router Ethernet LAN Port-------to my Cisco 10/100/1000 Router Internet WAN PortMy computers are Ethernet connected to my Cisco Gigabit Router Ethernet PortsDoesn't their FRONT (Primary) 10/100 Router attached to my Cisco Gigabit Router (Secondary) limit the speeds of my Etherne Ports attached to my computers to just 10/100 Mgb?The Xfinity site shows no detailed Netgear User Manual.

How do I route multiple SB302 switches at different sites and their VLANs?

Hello Cisco Support Community,
First thank you for any replies.
The video posted today on 302's and multiple VLAN's on one switch was nice.
Thank you, I have that working but it's not really what I need.
Though pictures are worth a 1000 words so I hope someone will post something similar to my question.
I have 7 - SB 302-08 switches with the most recent firmware. (updated firmware today, thanks to the video, and TG for the CLI)
All 302's are configured for layer 3.
This is my first experience with the SMB line of switches.
I have a main office and several satellite branch offices.
All locations are connected back with a "Q to Q" circuit on individual ports to a vendor supplied switch at the main office.
I need to link all branch office 302 switches back to the main office 302 switch and allow traffic amongst them.
Mainly traffic between each branch office and the main office.
There maybe a future need to incorporate VoIP on them as well, but that is a back burner issue.
These locations will have an individual VLAN and 302 switch but need to receive data from the main VLAN and possibly others.
I have a "core" SB 302 setup at the main office with its own VLAN.
Each branch switch has its own VLAN.
I would also like to have a centralized management VLAN for the switches.
In trying to configure the core 302 I keep losing connectivity and having to reset it.
On the branch switches I end up getting them to only link to themselves with different IP's and not the core.
I'm assuming this is caused by my not configuring interconnectivity using ACL.
Please let me know if you need additional information.
Thanks

Alllan,
Well first you want to make sure you are running latest firmware 1.1.1.8 I do believe
Next either console into the switch or you can turn on SSH/Telnet under Web gui (Security••àTCP/UDP services and make sure SSH/Telent is enabled)
Now we configure the switch via Cli
We need to enter global configuration mode.
Configure Terminal
(next add our vlans)
Vlan database
Vlan 10
Vlan 20
Vlan 30
Exit
(you can run show command to see your vlans)
do show vlan
(Now configure the port how you would like)
Interface GE1
Switchport mode access (this is making Gigabit port 1 an access port)
Switchport access vlan 20 (this command is changing access port vlan from 1 to 20)
(less configure a trunk port)
Interface GE2
Switchport mode trunk (this makes port 2 for trunking)
(Now less add our Vlans)
Switchport trunk native vlan 1
Switchport trunk allowed vlan add 10,20,30
Exit global configuration
(Use this command to copy your settings to startup)
Copy running-config startup-config
(Some screen shots attached)
I see you have a WRT54G router which i don't think support vlans unless you have 3rd party OS installed.
So currently is the SG300 swtich operating in layer 2 or layer 3 , guessing this is why you choose to move up to 300 series switch?
If the switch is not in layer 3 mode but in layer2 when setting it to layer3 the switch will default all pervious settings.
If the switch is set in layer 3 mode you might have forgot your default route
(Command setting default route)
configure terminal
ip route 0.0.0.0 0.0.0.0 192.168.1.1 (192.168.1.1 being address of your WRT54G)
Now you would need to set up ACL's to deny and allow what traffic you wanted to filter on the SG300
Also reading your post we would need you to call into support center SBSC @ 1-866-606-1866
This way we could get a better idea of your current configuration and assist with fixing or finding a solution for you.
you have 1 year phone support with this product
Thanks,
Jasbryan

Do I need a router or a switch

I have an adsl (UK) modem and it is linked to an Airport extreme giving a wireless network all works fine. I now need to take a fixed wire internet connection to a separate component of the electrical system for web based security monitoring. Clearly I could take the connection from the AE lan connection BUT the positioning and wiring in the house does not really allow this easily - so I wondering could I insert a router or is it a switch afetr the modem with one connection to the AE feeding the wireless network and a second wire to the security system?
Any thoughts ?

A router would be the best bet as it could run both at once. If you only need to monitor the connection once in a while a switch would be OK but a cheap router would be a better investment.

Wireless Router (BEFW11S4) not Switched on

I have a link sys wireless router. When i plugged in to the power, its not switched on. None of the Lights were glowing. Could you please let me know what could be the problem? i Tried in different sockets, its not getting switched on? Let me know what should i do?
Thanks in Advance
Nagakumar

I tried with diferent adapters, its not working. It is dead in the sense, failure of the router? how this could happened? Is this due to voltage fluctuations?I need to buy a new router?
Please let me know.

Router ea2700 and switch se2800

Good evening,
I have a router connected ea2700 on the Internet port to a switch se2800.
e switch is connected and everything is gigabit nas.
if I try to transfer a file from PC, gigabit ethernet, the transfer rate does not exceed 8 MB/s.
if I transfer a file from the NAS to the PC speed is 15 MB/s.
the support advised me to change MTU manufacturer parameters,to disable protection,and clone the mac address.
the situation has not changed.
if I configure the router in bridge mode, the speed is 22MB/s and 45MB/s.
it happened to someone?
thanks.
Francesco

good morning,
thanks for the reply.
the configuration that I've reported,does not allow the use of nat router function.
now after the switch off and on again, the situation seems to have improved.
is it possible?
thanks
Francesco

3750 as a router and a switch. sub-optimal routing problem

Objective: To limit the traffic on Vlan8. We are seeing traces from K1 or T1 to 192.168.1.4 like this:
1- 10.10.10.5
2- 10.10.20.1
3- 192.168.1.4
then
1- 10.10.10.4
2- 10.10.30.1
3- 192.168.1.4
or
1- 10.10.10.5
2- 10.10.200.1
3- 192.168.1.4
this causes the packets to travers vlan8 once to get routed by P61B then switched back across to reach the next hop 20.1 or vice versa.
How can we avoid this behavior?
Study the attached drawing carefully. Vlan 8 has 4 routers on it and the 3750s have routes to the 4 networks above them. packets are not routed between the 3750's

Hello Todd,
Could set up a debug ip icmp on the router 192.168.1.4 and ping it from both T-1 and K-1, I think this problem would be more clear to everyone.
If not mabybe you could provide the output of "show ip route" on the routes on this issue,at least on the routers/switch 192.168.1.2 , 192.168.1.3 and 10.10.10.4 and 10.10.10.5 and T-1, K-1.
for routes like 192.168.1.4, 10.10.10.2-5 and 20.20.20.2-3
Hope thats not to much info.
Thanks,
Vlad

Which way to enforce policy for endpoint from gateway router instead of switch

Dear team,
I am proposing ISE to customer. They want to deploy ISE as central authentication and policy point for users in branches. I would like to ask if this scenario is possible or not:
- When user client is plugged into access switch, the switch will use 802.1x or MAB in switch port
- After authentication, as normal method, we will push a dACL or VLAN change from ISE to switch in authorization statements. But customer dont want to apply port ACL on switch. They want to enforce policy from the gateway Router.
So is there any way to do that? I'm thinking about SGT but I dont have any experience on it. Please help to solve this problem. Thank you very much.
Kind regards,
Hiep Nguyen.

Hiep,
You can use authentication proxy to push ACLs for users on the router. However the port based ACL is your best approach because you can determine authorization at the port level and if the user moves so does the policy.
thanks,
Tarik Admani

Trying to add a Wireless router as a switch on an existing Wired network

Hi,
I'm having a lot of trouble with my WRT54GS v.2.0
I'm trying to add wireless access to my existing network here at work. I think the main network is using Dlink 40+ node switches.
I've been reading around and I've tried to turn off DHCP on the router, but when my computer tries to find a connection, it times out. I'm not even trying to get the wireless to work, just LAN for now.
The router will get an ip address assigned by the main network, so it's connected, but I can't get the computer through to the main network.
Is there anything I need to be setting up on the computer? Can this even be done?
Thanks,
Alex

please make sure that you dont use the internet port on the router, use the local ports...(1,2,3,4)

Intervlan Routing with 6500 switch

I am designing an upgrade to our current network that will contain a 6500 switch and i wanted to setup vlans with the switch. I know that this switch has the ability to perform routing on its own so i do not need an external router to route between the vlans but if that is the case what default gateway do i give each vlan? Do i give the vlan ip address as the default gateway for the end devices or do i use an IP address in the switch somehow as the default gateway?
Thanks.
Pete

Hi,
Think of the MSFC as a router with many different interfaces. Your router itself would only have one default gateway for all those interfaces. For the clients, they will sit in each VLAN that you create. The clients default gateway will be the VLAN IP address (or HSRP address) on the 6500 that they sit. So, if you create vlan100 and put an IP address of 10.10.10.1 on the vlan100 interface..the 10.10.10.1 address would be the gateway for the clients in vlan 100. If you create a vlan200 and put an IP address of 10.11.11.1 on that interface..all the clients that are in vlan200 would have the gateway address of 10.11.11.1.
Hope that helps.

Router power supply: Switch mode or linear?

I need to replace a failed power supply for a router - which model doesn't really matter but the router is a WRT54GS (12V 1000mA). Which is best - a switch mode or a linear power supply? Will either be just as good? Please only answer if you DEFINITELY know the answer. Cheers, Mike

Power adapter uses External, 12V DC, and 0.5A...
