Cisco Switching/Routing :: Internet Connection With Linksys SRW2048 Switch?

Jan 2, 2013

I have a problem with my switch. The model no. of the switch is as follows:

Linksys SRW2048 10/100/1000 48 Ports
Serial No: RJT00GC00395 GGR2906 MM

1. I am creating a home computer lab. I do have 3 servers HP ProLiant DL 385 G1. Two of them have 6 gigabit ports where as the third server has 2 gigabit ports.

2. Installed ESXi 5.1 on two servers where as installed FreeNAS on the third server and configured it as iSCSI storage and NFS storage.

Problem:

1. Every port works perfectly fine. However, when I keep connecting the ports of the switch to the ports of servers, internet gets disconnected.

2. Interestingly, my wireless internet also gets disconnected, the ports of the switch does not have any internet now.

3. This happens till I connect above 8-9 ports of the switch  to the servers.

3. However, when I remove the connection between the switch and the servers, internet comes, wireless internet starts working; and the port of the switch also gets internet connection when I check the internet connection of the individual ports one at a time.

Some more information:i do have internet service provided by Time Warner Cable. My internet speed is as follows:

Download Speed: Up to 15 Mbps
Upload Speed: Up to 1 Mbps

I do have a modem *** router by Motorola which has 4 gigabit ports.Model no: Motorola SURFboard SBG6580 i am assuming it is some thing related to bandwidth of the internet.

Cisco Switching/Routing :: 3560CG Switch Terminate On Internet Modem

Feb 4, 2013

I am facing with Cisco 3560CG Switch. We have a Cisco WS-C3560CG-8PC-S (Cisco Catalyst 3560-C Switch, 8 GE PoE, 2 dual-purpose uplinks, IP Base image) switch which will be a core switch and the internet link from the ISP is terminated on a Modem. The ISP configured the internet modem and provided the details such as Gateway IP, Subnet Mask, DNS IP address, Usable IP Address Block,  to configure the switch, where ew have connacted the Modem. When, I verified the details, there were only 4 IP addresses available under Usable IP address block. Spoke with the ISP and they confirmed that they cannot increase the IP Addresses (some limitation on the Modem) in the pool and we have to do NATing at the switching (Which we can't do, because of IP Base image limitation). About the network, it will be a flat network with only one VLAN which is used for Wireless Guest Access.

Cisco Switching/Routing :: 3750-X Stacking Switch By Switch

Nov 18, 2012

I have two 3750-X configured to be a stack and I am planning to re-rack these somewhere else.  What I would like to know is what are the effects of having the master switch itself lose power?  Does it immediately just make the member take over master (there should be no election since there are only 2 switches??) and there would be no loss of connectivity?

Cisco Switching/Routing :: 2 Internet Connection Connected To Same Core Switch 6509

Jan 25, 2012

i'm already has one internet connection is conecting directily to the Core Switch 6509, and the Switch is route any internet request with default route:
 
SW6509-conf)# ip route 0.0.0.0 0.0.0.0 10.170.10.10
 
10.170.10.10 is --> Next hop for the DSL router internal IP, and it's working fine.
 
We have a new internet connection with another ISP/ with another DSL router, how to connect both of them to exit from the Core Switch 6509.
 
is it ok if i make another default route to the Next hop to the new DSL router as:
 
SW6509-conf)# ip route 0.0.0.0 0.0.0.0 10.80.10.10
 
10.80.10.10 is --> Next hop for the new DSL router internal IP.

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 :: 3825 / Replacing Routing Function With 3750 Switch?

Jul 27, 2012

I have the task of replicating the router config on a 3825 router on a 3750 switch. Reason is we are taking out the router and replacing it with the switch to make use of the router for other functions.
 
Below is main part of the router config:
 
!
ip source-route
ip cef
!
!
multilink bundle-name authenticated
!
license udi pid CISCO3825 sn FCZxxxxxxx
!
vlan internal allocation policy ascending

[code].....
 
The 3750 switch I have runs C3750E-UNIVERSALK9-M, Version 12.2(55)SE3 on a LAN BASE license.
 
The first thing I have done is to order for a license upgrade to IP BASE which would give the support for OSPF routing.I do not see much of an issue with the Interface configs, however, I am not too sure about replicating the routing config on the switch.
 
My question is can I run the commands as shown for the OSPF routing on the switch? If not, can I get suggestions on how best to set this up on the switch?

Cisco Switching/Routing :: Cannot Reach Gateway Through Routing Switch (3750)

Mar 11, 2012

I'm running into what seems a basic ip routing config problem with a Catalyst 3750 (IP Base) switch. I have several VLANS configured on the switch with IP routing enabled, and the switch is connected to the inside interace of a new ASA 5520 as follows:
 
ASA5520 IP (Default gateway): 192.168.1.1Switchport Gi1/0/1 is configured as a routed port, IP address 192.168.1.3 255.255.255.0Example VLAN is VLAN 100, IP address 192.168.100.1 255.255.252.0 From the switch CLI, I can ping all VLAN addresses, as well as the ASA5520, and the client laptop I'm testing with from VLAN 100.
 
From the client laptop on VLAN 100, I can ping all switch interface and VLAN addresses (inter-VLAN routing is working), including 192.168.1.3, but I CANNOT ping the default gateway at 192.168.1.1.
 
Here is the relevant configuration information on the 3750:
 
!
no aaa new-model
switch 1 provision ws-c3750x-24
system mtu routing 1500

Cisco Switching/Routing :: Switch 3750-X Vulnerability

Jul 19, 2012

I had a bad expirience with Switch 3750-X. Because of an auditing security processess, my customer ran a software called "Nessus" to do a scanning of vulnerability on the network. When this software is point to switch, the process of the switch will next to 100% and reset. The software only do a listening on the ports to see what ports are opened and the switch should not reset because this. Bellow is the log os switch on the moment of test; we note that the processess 'HTTP' rise moments before the switch reset. I disable the HTTP service on switch but the problem persist. The test was made only one machine connected to switch.

Cisco Switching/Routing :: Setting MTU On A 3750 Switch?

Dec 12, 2010

The question is: Will a 3750 switch route Jumbo frame sizes (e.g. 9000 MTU)?
 
We know that we can change the System MTU to 9000, and someone on a previous thread said that we can change the Routing MTU to 9000 as well, although I couldn't figure out how to do that.  However, regardless of how we configure the System MTU and Routing MTU, I don't think we're able to adjust the MTU on L3 VLAN interfaces, so if we want to actually "route" between VLANs on the switch, we're limited to 1500 MTU.
 
Our situation is that we have a customer connecting to our 3750 switch, and this customer wants to use Jumbo frames.  The customer connects to our 3750 switch via their own VLAN, with their own L3 VLAN interface configured on the switch.  The customer will point their traffic towards the L3 VLAN interface, then we want to route them onto another VLAN, via a different L3 VLAN interface, before forwarding their traffic.  Because of the limitations noted above, specificially regarding the routing between these VLANs via L3 interfaces, I do not think we'll be able to support 9000 MTU frames on this 3750 switch.  I think the L3 VLAN interfaces will limit us to 1500 MTU, regardless of what we configured via the global System MTU and Routing MTU settings.

Networking :: Zywall USG200 Internet Connection If Modem And Switch Got Switched In

Nov 25, 2012

I got a retired Zyxel Zywall USG200 from work. Its working just subs ran out. Was thinking of putting it on my home network, any reason not to? I'm a sys admin, not network engineer, so while I'm capable I'm not an ace with this type of equipment.. Which is why I want to mess with it. I'm currently RTFM and it seems pretty straight forward. If it seems like a viable piece of equipment I'd like to use it full time.
How bad can I break the internets and subject myself to the wrath of my wife's downed internet connection =D if I plug it in between modem and the switch?

Cisco Switching/Routing :: 3750-X Switch Freezes After IOS Update?

Mar 27, 2013

I have a 2 member 3750-x switch stack that was upgraded to 15.2 today via CNA. All the files were transfered and expanded correctly and it got to the step where the switches needed to be reloaded but on reload they froze.
 
I connected a console cable and power cycled the stack. I see the flash initialize and then the IOS image start to load. Lots of @ symbols and then nothing. It just sits there. The system light on the switches, while flashing green during the load, is now off. No light at all. But fans are running and the process will repeat itself if power cycled.

Cisco Switching/Routing :: Stack Behaviour Of 3750 Switch

Nov 17, 2012

I configured 3750 A  switch with vlan 20 and its IP address 192.168.20.41Its default gateway was 192.168.20.3Then i configured 3750 B  switch with same default gateway and vlan 20 IP   192.168.20.43My question is now when we stack it becomes single switch and now vlan 20 ip address is 192.168.20.43 thats only IP i can see.So how does stack switch choose vlan 20 IP?Does it choose highest IP address between two switches if they have same vlan 20 as in my case?Also when i go to switch 3750 b by session command and do sh ip route  it does not show ip default gateway .Also it shows vlan 20 as admin down .
