We have two 3750-x stacked switches with IP base license. We need to upgrade them to IP services license. I read some where that it is possible to install IP serivces license to only management switch and no need to purchase/install same license to other switches on the stack. But, I could not find/recall where I read it and as far as I know it was not official cisco documentation.
View 1 RepliesI have a 4 member stack of 3750's. We would like to take advantage of wccp and we understand that we will need to upgrade our switch licensing from IPBase to IPServices. My question is do we need to pay for a license for each member in the stack or does one IPServices license upgrade cover the whole stack?

Im trying to stack 2 3750E-24PD-S and 2 3750X-12S-S. The 2 3750E finds eachother and stacks with one master as they should. The problem is that and the 3750X does the exact same thing instead of joining the 3750E stack.Both runs the same IOS (c3750e-ipbasek9-mz.122-58.SE2).The stackingcables are connected like following atm (I tried booting up the switches one at a time and all at once, no difference in the result).
View 8 Replies View RelatedI was wondering what general steps might be taken in order to "replace two(2) 3750 (stacked) with one (1) 3750X - Server Access". General steps and what I might have to do configuration wise. I know i'm copy pasting the existing configs into the new switch, but are there any caveats?

View 2 Replies View RelatedI will be start with the disclaimer that I am very technical, but a huge novice to the enterprise-grade Cisco swtiches.
How IOS software versions are licensed on a Catalyst 4507 switch? I am very confused at this point.
For example, if I buy IOS Enterprise Services for a new Catalyst 4507 switch, what form does the software license take? Is the license embedded on the switch? Does it come as an e-mail or certificate with a PAK? Does it come on a CD?
We sold a 4507 with Enterprise Services to a client, and they are saying they don't have the right IOS version installed. I assumed there must be some license key they needed, but the Cisco licensing help desk does not seem to indicate there are any licenesable items on our sales order number (even though IOS Enterprise Services is a line item on the sales order).
I know there was a disk that came with the switch with an Enterprise Services .BIN file on it, but I had assumed that was just a software version image, similar to the images I can download off the Cisco website. But is this actually the license key?
Since I can download image files off the Cisco website, I assumed there must be some other key needed to activate the license.
Switch is Catalyst WS-C4507R+E
Redundant Supervisors are WS-X45-SUP6-E (Supervisor 6-E)

View 12 Replies View RelatedI 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?

View 1 Replies View RelatedI currently have a stack of 3750G switches with a cross stack etherchannel connected to a 3750E stack in the distribution layer.The 3750G stack is running 15.0-2SE IP Base. I began noticing the Mac flap issue when I was Re-enabling dot1x on the switchports. As first I thought dot1x maybe have contributed to this so I removed it from the stack temporarily.I am still seeing Mac flap logs usually when a machine reboots or re-connects back to the network. These are all wired desktops.I started looking at the etherchannel configuration which is using LACP. The 3750E stack looks fine with all ports in mode active. On the problematic 3750G stack I noticed 3 of the ports in the etherchannel set to mode active and 1 port set to mode passive. The port shows as bundled but I can't imagine this is ok.The only other difference on this one port is there is no mls qos commands like on the other 3 interfaces in the port channel.I mainly need to know what the Mac flapping is about. Whether it is a bug or related to the current etherchannel configuration.

View 1 Replies View RelatedHow many Switches can be stacked with WS-C2960S-48FPD-L at a max..
As per my Knowledge it is 4 and as below..
Switch 1 to Switch 2
Switch 2 to Switch 3
Switch 3 to Switch 4
Switch 4 to Switch 1
If yes then, is it mandatory to do the "Switch 4 to Switch 1" stack. why am I asking this is because this stack requires a long cable and the cable which comes with the Switch is only 0.5M.
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. [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.
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

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 3 Replies View RelatedI'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.

My company is beginning to have a lot of sites were we are stacking 3 to 4 C2960S-48 switche.This is making "show running-config" very very long because of the 4 x 48 interfaces.I can’t find a CLI command that show me the running-config of a ranges of interfaces. If I for example would like to see running-config for switch 3 (interfaces 3/0/1-52)The Show Running-config will show all the interfaces (for the two first swtiche = 104 interfaces), which take a time before I reach to switch 3.I miss a CLI command like: show Running-config switch 3, or module 3, or show running-config interface range x/x/x-x ?I’m well aware of the CLI command show running-config interface x/x/x, but this will only show me one interface.
View 3 Replies View RelatedI have two 3750x stacked switches , both with the latest firmware on them. I enter the configuration onto one switch and it obviously copies over onto the other switch. Although in the configuration I have both a console username and password and an enable password, when I try to log onto the initial switch that I entered the configuration on, I am prompted for a username and password, which works fine, but when I try to enter enable mode i get an error stating that no password has been set. However when logging onto the other switch I am not prompted for a username or password but when I try to enter enable mode I am prompted for a password and can access it with no problems.

View 2 Replies View RelatedI 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.

View 3 Replies View RelatedThe 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.
