I got 10 Catalysts 3750 (all of them identical) and I got the IOS Update. Anyway I only have service contract for 4 of them.
Am I allowed to update all of them? Or only the four devices which have the service contract?
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.
I am working at a client site today on a routing issue. I am currently working on an issue where a 3750 switch running EIGRP will not update its neighbor router when a network statement is added to the eigrp instance.The neighbor is a 3825 router.
Both the switch and the router have a common network which is 192.168.36.0/24.
Both the switch and the router are in a neighbor adjacency.
Both boxes have "no auto-summ" in the routing configuration instance.
I can run debugs on both routers (debug eigrp packets) and then I can watch queries and updates when I issue "auto-summ" or "no auto-summ". Also I see a "graceful restart" for the peers when this is done.I had an expectation that when I added the network (this is just an arbitrary network for testing, which is 172.16.69.0/24). I wanted to watch this network being sent in an update to the neighbor router.When I add the above mentioned network, there are no updates packets sent from the 3750 to the 3845. I have not had success to this point trying to resolve. I have followed the Cisco document "Troubleshooting EIGRP Flow Chart", but have exhausted all it has to offer and now it is at the point where it is telling me to contact TAC.
Do I need the Universal image to perform stftp on a 3750 or 3750-X?

Would there be any reason why a universal image wouldn't stack correctly with other switches running the single .bin file?

I bought a secondhand small business router (model 1941 Integrated Services Router) for personal use. It runs version IOS 15.0(1)M1 software, which seems to work well, but I'd like to download a firmware update that addresess some of the security flaws in this software. When I tried the download process it told me I need to buy a service contract first? Is this right, or am I doing something wrong?

I've recently tried to update the modem firmware on an 887M that is actually using an Annex M service and after rebooting to kick in the new modem firmware, the router loses sync. I've tried this with various other 877, 877M, 887 and 887Ms on normal Annex A services with no problems, but this Annex M service doesn't like it at all.
View 2 Replies View Relatedyou can update your ios for free within the 90 day warranty.e.g. a customer bought a asa 5510 and installed was a old version of the ios. now our customer complains that he wants to have the current version.but as far as i know he would need a smartnet in order to get the current ios.
but i think to remember that someone told me that you can update your ios device withthin the 90 day warranty. true?

This feature doesn't work as advertised on the Release Notes and other documentation. After 12 hrs of lab work and a tlwo day support call to TAC, they finally came back to me that:
IOS Upgrade works well if you use the command force-reload, without force-reload, it won't work. --"of course with this command the complete stack will go down and the purpose of RSU will not serve"

We 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?
Basically I have netflow which i'm trying to use to export to a netflow collector. I'm pretty sure that the 3750-X does support netflow. I've recently updated IOS on the 3750-X to support flexi netflow.For some reason the netflow packets are not being exported to the server. I'm using Opmanager which should present the netflow stats in the form of a graph. I'm using a universal IOS image. (C3750E-UNIVERSALK9-M), Version 12.2(58)SE2 3750-X WS-C3750X-24T-S

View 5 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.

DFM 3.2.0, part of LMS 3.2;
I tried to reinitalize the DFM database, but that caused all sorts of other issues like my ANIServer not running anymore etc. I have a ticket open with TAC for that issue though.
I 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?
In 3750 switch,I have configured intervlan routing.I have three vlans Vlan 10,vlan 20,Vlan 30 and I have assigned IP address for that Vlan.In vlan 10,I have connected one systen gigabitethernet 0/1 interface.From my system I am able to ping vlan 10 ip address but I can't able to ping other vlan ip address (vlan 20,vlan 30).Is it possible to up the protocol for all that time.

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)
