If i try to ssh to a 3750 switch on our 4th floor, it ask's me for a username and password.
After entering the password, it doesnt connect. It shows a blank screen with a flashing cursor.
If i connect to the switch directly via console port, i can see port uplink and downlinks but still cant do anything more.
my screen goes blank if not used after about 10 mins how do i extend time?

I am trying to change the name of my wireless network but when I go to the 192.168.1.1 and type in my password, it just goes to a blank screen. I've accessed my router a lot of times before this way. It is a lisksys router.

View 1 Replies View RelatedI'm running a new RV042 with the latest firmware (4.1.1.01). I set it up about 2 weeks ago and have been running it without an issue. Today I tried to go in to the web utility to make some changes. I was prompted for the userid/password, which it appeared to accept (if I typed in the wrong ones it rejected it), and then the screen went blank (normally I would get the status screen now.) Instead the screen I get is the light blue of the log-in screen, but there is nothing on it. The router has switched to the page https://192.168.1.1/home.htm I have tried different browsers and accessing it from different computers - the situation is always the same. I have power cycled the router, and there is no change. I suspect the next step is a manual reset to factory defaults - but of course I would rather not (as I didn't save all my settings of course!)

View 1 Replies View RelatedWe have a new building where we added 3 network closets with 3750x stacks.We have 2 fiber gig ports connected to 2 microwave units and etherchanneled the to ports
We have the same setup at the corporate office except the connection is 2 fiber gig ports on a 6509. The 6509 is doing the routing
Now the problem is that we lost the connection to the management interface on only one of the three closets after a few days running. But some workstations at the corp office could reach it... others could not. The workstation were on the same VLAN. We solved the problem for a few days by shutting on of the fiber ports on the etherchannel. But is started happening again... now with PCs being installed at the new location.
The PC that was not working on the 3750x side could ping across to the 6509 but no further then that. It seems like an arp issue not routing because some devices are reachable and fully operational throughout the network.

When I plug the phones into the switch they power up just fine but the phones will not dial out as they have little x's by the line. I have also tried going through the set up of the 3550 but get stuck in one place. When I go to the 10.0.0.0, the screen will not allow me to enter the telnet page or allow me to enter any information.

View 1 Replies View RelatedWe have a stack of switches that is at the max number of members allowed in the stack. Problem is we are running out of port density and need to add more ports. So instead of adding a whole new stack I would rather replace 2 of the 24-port swicthes with 48-port switches.
If the two 24-port swicthes we are removing are stack members and neither of them are the stack master, I should be able to replace the 24-port switches with the 48-port switches without bringing the master offline? If the new 48-port switches are running the same IOS version as the current 24-port swicthes, they should add themselves to the stack?Would I have to tell the new 48-port swicthes what switch numbers they are replacing in order for them to be added to the stack since we are at the max number of members?Also since the 48-port swicthes are replacing 24-port switches will the master give the 48-port switches the configuration for only the 24-ports?
I'm running Windows 7. As stated in the title, once I see the screen blink, I know I have a few moments of connectivity left. The screen will continue to blink, then the wireless network connection icon goes red with an "x" through it. The computer continues to work (albeit with the screen blinking), but with no connection to the Internet. Checking Device Manager indicates no conflicts. Manually pressing the "wireless connectivity button" on this Compaq, which shows green=connected, only turns it red for a second, then back to green as if the adapter is enabled. Doing this prior to the blink-failure cuts the wireless connection as it should. I added iTunes about a month ago, the problem started about two weeks ago.
View 2 Replies View Relatedsome of our switches have the switchport mode trunk command configured between the 3750 switches but other 3750 switches connected to our 6509 core switch do not have the switchport mode trunk command to permit Vlans from going across the swtiches instead it has an ip address and says no switchport what is the difference between does two. Is trunking used only for Layer 2 and L3 is used to route interface vlans?
View 2 Replies View RelatedI have a network with a Catalyst 3750 as the main switch and then some Catalyst 2960 switches that are plugged in to that. I have a server running windows server 2008 with a couple of virtual machines running in Hyper-V. I created 4 VLANS listed below and gave the 3750 the following IP Address.I would like the 3750 to only be configurable from VLAN 40 but currently every VLAN can connect to it, I noticed in the standard web page settings there was a setting for "Management VLAN" but it was set to 1 and would not let me change it, I kinda assumed that was for the management port in the back.-Now the tricky part, I was trying to set up routing between the VLANs and so far I have only been able to get a sort of "all or nothing" routing to work. I can turn IP routing on and add two or more VLANs to the routing and it works fine. But what I was hoping to do is create a couple of "junction vlans" that would only route to one or two other vlans. For instance, I wanted to create a VLAN 100 that routed to VLAN 20 and 30 but nothing else. I also want to route VLAN 1 just to VLAN 30, and so on. I am able to do each one of the cases but only one, it seems like the switch only supports one "routing table" am I missing something or is this just a limitation of the switch?

View 2 Replies View RelatedI have a network with several catalyst 2960 switches and one catalyst 3750. I have created two VLAN and set up the proper routing and everything is working fine there. I have a client/server application that used multicast in the initial start up for the client to determine available servers, the issue is one of my clients is on a different VLAN then the server. I am able to route the multicast using MVR as long as both the server and the client are plugged into the 3750 by creating a static route, making the server a source port and the client a receive port. Unfortunately I need the client and the server plugged in to different 2960s. My question is how do I establish multicast routing between the two and perferably do it dynamically (always route multicast traffic from one VLAN to another).
View 2 Replies View RelatedI 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. [code]
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.

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?

View 1 Replies View RelatedI am using a 3750 as a default gateway for multiple Vlans on a few 2960 switches. The trunk lines are configured and working and I have assigned ip addresses to each of the Vlan interfaces on the 3750. My issue is that I can only ping the ip address on the Vlan interface of the 3750 if I have a working computer plugged directly into the Vlan on the 3750. I only have 3 vlans on the 3750 that have hosts directly connected (vlans 2, 10 and 40) the other vlans ( 20 and 70) don't have any clients plugged into them on the 3750 but the hosts reside on 2 different 2960s that connect via trunk ports. How do I keep the vlan interface on the 3750 switch pingable when I don't have hosts directly connected in that vlan on the 3750? (yes, I have enabled ip routing on the 3750)

Created access list to identify traffic:
access-list 10 permit 10.2.3.59 (test workstation on vlan 3)
Created policy:
route-map TestASA permit 10
match ip address 10
set ip next-hop 10.2.0.3
Assigned policy to the user vlan3:
ip policy route-map TestASA
Results:It changed the default gateway to the above gateway but i could not access any resources on any other vlan, could not access resouces accross wan.
