My question is about WS-C3750E-48TD-S and WS-C3750E-24TD-S Switches
What are the limitations of the mapping of VLANs on this device? Is it limited by number or by interface? Does the configuration of an interface has spread all interfaces ?
I have two Switches which i need to put in a same stack - WS-C3750E-48TD and WS-C3750G-48TS . Possible to do so and also which IOS to put in both the switches as WS-C3750G-48TS is having lower RAM and flash.Whether can i put following IOS in these switches and connect them in a stack as i have read that IOS -- 15.0.1. SE are compatible with both the switches.
a . c3750e-ipbasek9-mz.150-1.SE.bin in switch - WS-C3750E-48TD
b. c3750-ipbasek9-mz.150-1.SE.bin in switch -- WS-C3750G-48TS
Is that possible add WS-C3750-48TS-E to ws-c3750e-48td stack?

I checked and found two registered bug id: CSCtq86186 / CSCso81660.I would like to know what is the best IOS version to update my switch, IOS 15.0.2 SE2 or 12.2.58 SE2, by the way, my environment is very critical (data center) and the version 15.0.2 SE2 is very recent, but its stable ?In both versions the problem are fixed?
7x stack WS-C3750E-48TD-E orignal code 12.2.35...i wanted to get it to 15.0.1 so as a test i disconnected top switch (not the master ) and installed via archive download-sw /allow upgrade 15.0.1.tar. and it worked away fine...
so i moved onto the stack, issued the same command, image loaded rebooted and stack hung..Consoled in and switch was unable to boot..looping on trying to load flash. [code]
I was wondering if I can stack WS-C3750E-48TD with WS-C3750G-12S together to created a single logical switch.

I want to connect WS-C2960S-48TD-L switch to WS-X6708-10G-3CXL module in Cisco WS-C6503-E switch. WS-X6708-10G-3CXL is C6K 8 port 10 Gigabit Ethernet module with DFC3CXL which requires X2 module. on the otherhand, WS-C2960S-48TD-L requires SFP+. Now is it possible to interconnect these two switch interfaces if I use LIU in between. or does WS-X6708-10G-3CXL module supports CVR-X2-SFP+ to use SFP+ transceivers.

View 9 Replies View Relatedthe incoming fiber on ports 9 and 10 are on different subnets. I need to map the subnet on port 9 to ethernet ports 1-9 and port 10 is on its own. I have the device IPv4 address set to a static address on the same subnet as port 9. I don't know if there's an easier approach, but I attempted to map the ports using vlans (See the attached screenshots). We don't yet have the fiber link established for port 10, so I haven't had a chance to test, but I wanted to confirm that my configuration is sound. I used the default vlan for ports 1-9, because I need to manage through that subnet. I added vlan 10 for port 10, but I don't know if I have it configured correctly.

I'd like to create about 10 vlans for the different departments and then configure intervlan routing as needed. Currently we have all unmanaged switches and it's just a huge broadcast storm on the network. We are upgrading our Cisco 800 router to an ASA5505 sec. Plus license. I need some recommendations on switches. Of course, this needs to be done as cheap as possible.... Is there a way to use the ASA to configure all the vlans and intervlan routing and access lists and use a cheaper switch to provide the access layer to hosts?

Laptops on each port with 10.10.10.2 and 10.10.11.2 configured on them. I can ping from 10.10.10.2 to 10.10.11.1, but not to 10.10.11.2.What do I have to configure to be able to get the 2 laptops to talk to each other?
I am setting up a vm environment for a customer in my lab off site. I have two stacked 3750-x switches, a san, and threes UCS c220 M3S servers for hosts. I am trying to separate the lan traffic, san iscsi traffic, and san management traffic using vlans. The problem is i'm unable to communicate cross vlan with my current config, which I have attached to this post. The only noteworthy things in my conifg is that the ip route 0.0.0.0 0.0.0.0 192.168.83.6 is referring to a switch stack they have on site, that I will connect this stack to using the first two trunk ports on each switch, that I do not have here in the lab. I don't want to cause any confusion in why I have things set a certain way.

I have tried to test copy tftp: numerous time with no success.

I can ping from laptop to gateway) and I can ping from the switch to my laptop using ping vrf production x.x.x.254.

View 2 Replies View RelatedI recently set up a Cisco 881 to cover a small business network. The router is currently set up and working as expected. We recently decided to move to VoIP phones and here is where I'm running into some issues.
First an overview: We run a network with a cable internet WAN connection, this connection is DHCP, however we have a static IP through our ISP. We also have a block of 30 additional IP addresses for one to one mapping as we need them. The new VoIP system is being run over T1 lines throughout the township (we are a municipal organization) and the VoIP system is being run to about 5 buildings in the township.
This brings me to the topic of VLANs. As the phone engineer explained it to me, there is a network set up over the T1 that allows the VoIP equipment to talk to one another and operates all of the VoIP phones on one network. The equipment that is being installed at our building connects to the network over the T1 and "talks" to the other equipment on the network. The engineer wants to create a VLAN and run it on ports fa1 and fa2, with the fa2 port being connected to the actual "MPLS" (their term) that connects to the T1 and into the cloud, and the fa1 port connected to the internal phone switch.
TLDR; The problem is this: When we attempt to set up the VLAN on ports fa1 and fa2, we have no connectivity with the other units in the external VoIP cloud. Pinging while directly connected to the "MPLS" yields successful pings, while pinging from the router with the "MPLS" connected to fa2 yields failures. I'm going to post the running config below, I feel like what we're doing should be working. I asked around about subinterfacing, but others seemed to think this was not necessary.

Scenario:
vlan10

vlan20

vlan10 needs internet.
I have a static ip internet which is 200.33.22.11 gateway: 200.33.22.10 I have a router configured working as gateway, It has ip 192.168.2.1.
I have configured two vlans. But when I try to check if vlan has internet, it doesn't work.
I have the need to filter multicast between vlans as described below. PIM Sparse-Mode is being utilized for this multicast network and changing any Vlan to PIM Dense mode is not an option.
- Vlan 217 and Vlan 4 should not be communicating on mcast with any other vlan, including eachother (each vlan isolated).
-Vlan 64 and Vlan 80 are able to communicate witch each other on mcast but not with any other vlans (isolated vlan group).
-All other vlans can communicate mcast freely.
What I've created thus far is below. It does not appear to be the most elegant solution and would be difficult for the administrators to adjust as new requirements come along. Yes, I will be adding the appropriate link-local multicast addresses so as to not break routing and other dependent technologies.
ip access-list ext ANY_CONN
permit ip any any
ip access-list ext MCAST_INTRA_217

We have the need to create a large number of VLANs on one of our networks. We're talking about 60! These will all terminate on a pair of 6509-E switches (building core). We use MSTP as a standard on our network so I'm going to stick with that so that we can dramatically reduce the number of STP instances needed. However, regarding the SVIs (default gateways) is there any reason why creating 60 of these guys would be considerd a big no-no? Or would you expect the 6509s to deal with them like a boss?

I need to set up a VLAN. We just bought the SG500x switches and we need to create several VLANs.
So for example:
192.168.1.x --> Vlan 1
192.168.2.x --> Vlan 2
192.168.3.x --> Vlan 3
What I would like to know is how do I come about setting this up and do I have to do something with my DHCP server to allow this to happen?
Is is correct that vlan's exceeding 128 runs without spanning-tree.?

Is this supported on a 3750X ?? A router has two VRFs and its lan interface is a trunk with 2 VLAN IDs, let say VLAN 10 and VLAN 20. The ip address subnet of these two vlans is the same (therefore , they are in different VRFs)
fa0/1
VLAN 10 = 10.15.4.9 (VRF A)
VLAN 20 = 10.15.4.10 (VRF B)
This router is connected on a 3750X switch. There is a firewall connected to this switch also, which is default gateway for several VLANs including VLAN 10 (10.15.4.1)
The goal is that VRF B ip can talk to 10.15.4.1 and VRF A can talk to 10.15.4.1 but VRF B can't talk to VRF A (10.15.4.9 <-> 10.15.4.10)
FW |--- TRUNK VLANs 1,2,3,4,10 ---------| SWITCH |----- TRUNK VLAN 10,20 -----| ROUTER (vlan 10 = VRF A, vlan 20 = VRF B)
I think this is not supported on the C3750, as my promiscuous port is located on a trunk.
